Change phone number format - asp.net

I have phone number field in database. It has already data.
I want to change my phone number format to "XXX-XXX-XXXX"
Current database has no any phone format.
So there may be garbage data. I have already applied validation for new records but now I want to change my existing data also.
Is there any specific way through that I can change my existing data. And make all phone numbers to follow this format.
Please advice.

Create function to remove the non-numeric data and do the formatting
CREATE FUNCTION [UDF_STRIP_NONNUMERIC_DATA](#str VARCHAR(8000))
RETURNS VARCHAR(8000)
AS
BEGIN
WHILE Patindex('%[^0-9]%', #str) > 0
BEGIN
SET #str = Stuff(#str, Patindex('%[^0-9]%', #str), 1, '')
END
RETURN #str
END
You can use STUFF function to inset the - between phone number
Select left(Stuff(Stuff(dbo.[UDF_STRIP_NONNUMERIC_DATA](Phone),4,0,'-'),8,0,'-'),12)
From yourtable
If you are using SQL SERVER 2012+ use can use FORMAT function (thanks to LukStorms, who mentioned it in comment)
SELECT Format(Cast(dbo.[Udf_strip_nonnumeric_data](Phone) AS BIGINT), '###-###-####')
FROM yourtable
To update
Update yourtable
SET phone = left(Stuff(Stuff(dbo.[UDF_STRIP_NONNUMERIC_DATA](Phone),4,0,'-'),8,0,'-'),12)
Demo
declare #str varchar(100)= '9225-123-4567'
select left(Stuff(Stuff(dbo.[UDF_STRIP_NONNUMERIC_DATA](#str),4,0,'-'),8,0,'-'),12)
Result : 922-512-3456

declare #phone varchar(24)
set #phone = '(334)789-4532'
--set #phone = '314789-4532'
--set #phone = '3457894532'
--set #phone = '534-789-4532'
SELECT
LEFT(N,3) + '-' + SUBSTRING(N,4,3) + '-' + RIGHT(N,4)
FROM
(SELECT CAST(CAST((
SELECT SUBSTRING(#phone, Number, 1)
FROM master..spt_values
WHERE Type='p' AND Number <= LEN(#phone) AND
SUBSTRING(#phone, Number, 1) LIKE '[0-9]' FOR XML Path(''))
AS xml) AS varchar(MAX)) as N) as N

Ok, to replace all non-numeric characters, look at this.
Here is a sample script (copied from that link) to show you how it works (You'll need to modify this to fit your table name and column names:
-- Step 1: creates table to use to hold every char in every phone number
if object_id('dbo.tally') is not null drop table dbo.tally
select top 10000 --change to fit max length of phone number
identity(int,1,1) as n
into dbo.tally
from master.dbo.syscolumns sc1,
master.dbo.syscolumns sc2
-- add pk to maximize performance
alter table dbo.tally
add constraint pk_tally_n
primary key clustered (n) with fillfactor = 100
-- Step 2: Create temporary table holding three bad phone numbers
declare #phonetable table
(uniqueid int identity(1,1),
phone_number varchar(500))
insert into #phonetable (phone_number)
select '01234-567-890' union
select '012345 6789ext' union
select 'n/a' union select '...12345.....';
-- Step 3: identify, for every character, whether it is a number or not,
and remove the non-numeric ones
with cte (uniqueid, phone_number, goodchar, badchar) as
( select uniqueid, phone_number,
case when substring(phone_number,N,1) not like '%[^0-9]%'
then substring(phone_number,N,1) end as goodchar,
case when substring(phone_number,N,1) like '%[^0-9]%'
then substring(phone_number,N,1) end as badchar
from #phonetable , Tally
where phone_number like '%[^0-9]%' and N <= len(phone_number) )
select distinct phone_number,
isnull( stuff (
( SELECT '' + goodchar
FROM cte t1
where t1.UniqueID = t2.UniqueID
FOR XML PATH ( '' ) ) , 1 , 0 , '' ) ,'')
as clean_phone_number from cte t2
to display the numbers with formatting, just extract the appropriate pieces and re-concatenate them with the dashes.
Select case len(phone)
When 10 then left(phone, 3) + '-' +
substring(phone, 4,3) + '-' +
substring(phone, 7,4)`
When 7 then left(phone, 3) + '-' +
substring(phone, 4,4)
Else '' end
To create a computed column
Alter table Add Column FormattedPhone as
case len(phone)
When 10 then left(phone, 3) + '-' +
substring(phone, 4,3) + '-' +
substring(phone, 7,4)`
When 7 then left(phone, 3) + '-' +
substring(phone, 4,4)
Else '' end

If you don't mind a UDF
Select [dbo].[udf-Str-Format-Phone]('334)789-4532')
Returns
334-789-4532
The UDF
CREATE FUNCTION [dbo].[udf-Str-Format-Phone] (#S varchar(max))
Returns varchar(25)
AS
Begin
Declare #Return varchar(25)
;with cte0(N) As (Select 1 From (Values(1),(1),(1),(1),(1)) N(N))
, cteN(N) As (Select Top (Len(#S)) Row_Number() over (Order By (Select NULL)) From cte0 N1, cte0 N2)
, cteS(S) As (Select Substring(#S,N,1) From cteN Where Substring(#S, N, 1) LIKE '[0-9]' FOR XML Path(''))
Select #Return = IIf(Len(S)>=10,Stuff(stuff(S,4,0,'-'),8,0,'-'),Stuff(S,4,0,'-')) From cteS
Return #Return
End
-- Syntax : Select [dbo].[udf-Str-Format-Phone]('(334)789-4532') -- Returns 334-789-4532
-- Syntax : Select [dbo].[udf-Str-Format-Phone]('Phone:7894532') -- Returns 789-4532

Error in concatenation of `LISTAGG` function[Not a duplicate question] [duplicate]

I have the following table TEMP
I want to create a pivot view using SQL, Ordered by CATEGORY ASC ,by LEVEL DESC and SET ASC and fill in the value .
Expected output:
I have tried the following code but unable to get a workaround the aggregate part which is throwing an error:
SELECT *
FROM
(SELECT
SET, LEVEL, CATEGORY, VALUE
FROM
TEMP
ORDER BY
CATEGORY ASC, LEVEL DESC, SET ASC) x
PIVOT
(value(VALUE) FOR RISK_LEVEL IN ('X','Y','Z') AND CATEGORY IN ('ABC', 'DEF', 'GHI', 'JKL')) p
Furthermore I want to know if there can be any method for dynamically adding the columns and arriving at this view for any table having the same columns (so that hardcoding can be avoided).
I know we can do this in Excel and transpose it, but I want the data to be stored in the db in this format.
A stored function(or procedure) might be created in order to create a SQL for Dynamic Pivoting, and the result set is loaded into a variable of type SYS_REFCURSOR :
CREATE OR REPLACE FUNCTION Get_Categories_RS RETURN SYS_REFCURSOR IS
v_recordset SYS_REFCURSOR;
v_sql VARCHAR2(32767);
v_cols_1 VARCHAR2(32767);
v_cols_2 VARCHAR2(32767);
BEGIN
SELECT LISTAGG( ''''||"level"||''' AS "'||"level"||'"' , ',' )
WITHIN GROUP ( ORDER BY "level" DESC )
INTO v_cols_1
FROM (
SELECT DISTINCT "level"
FROM temp
);
SELECT LISTAGG( 'MAX(CASE WHEN category = '''||category||''' THEN "'||"level"||'" END) AS "'||"level"||'_'||category||'"' , ',' )
WITHIN GROUP ( ORDER BY category, "level" DESC )
INTO v_cols_2
FROM (
SELECT DISTINCT "level", category
FROM temp
);
v_sql :=
'SELECT "set", '|| v_cols_2 ||'
FROM
(
SELECT *
FROM temp
PIVOT
(
MAX(value) FOR "level" IN ( '|| v_cols_1 ||' )
)
)
GROUP BY "set"
ORDER BY "set"';
OPEN v_recordset FOR v_sql;
RETURN v_recordset;
END;
in which I used two levels of pivoting : the first is within the inner query involving PIVOT Clause, and the second is in the outer query having the conditional aggregation logic. Notice that the order of levels should be in the descending order( Z, Y, X ) within the expected result as conforming to the description.
And then invoke
VAR rc REFCURSOR
EXEC :rc := Get_Categories_RS;
PRINT rc
from SQL Developer's Command Line in order to get the result set
Btw, avoid using reserved keywords such as set and level as in your case. I needed to quote them in order to be able to use.

SQLite insert select result multiple times

I have a database with three tables 'contacts', 'names', and 'contact_names'.
create table contacts(id integer, gid integer, sid integer);
create table names(id integer primary key, name text);
create table contact_names(fullname text);
insert into names(name) values ('Eberhard');
insert into names(name) values ('Esche');
insert into contacts values(1, (select id from names where name='Eberhard'), (select id from names where name='Esche'));
Now I want to insert the pair 'given name+surname' twice, once as 'given name+surname' and once as 'surname+given name'. What I currently have is a statment like this to generate these names:
SELECT gTable.name || ' ' || sTable.name AS name1, sTable.name || ' ' || gTable.name AS name2 FROM
(
SELECT name FROM names WHERE id=2
) AS gTable,
(
SELECT name FROM names WHERE id=1
) AS sTable;
What I am not able to perform is to insert these names now to table 'contact_names' using something like this:
INSERT INTO contact_names VALUES (name1), (name2) WITH
SELECT gTable.name || ' ' || sTable.name AS name1, sTable.name || ' ' || gTable.name AS name2 FROM
(
SELECT name FROM names WHERE id=2
) AS gTable,
(
SELECT name FROM names WHERE id=1
) AS sTable;
As result table 'contact_names' shall contain the two entries (rows) "Esche Eberhard" and "Eberhard Esche". Does anyone have a clue how to achieve this? Of course I could do the select statement twice, but I would prefer to do this with one select.
BR, Udo
PS: Maybe it is useful to explain why I want to do that. The INSERT statement for 'contact_names' shall be performed by a trigger that is called on removal of entries from 'contacts'. If I remove a row for instance with
DELETE FROM contacts WHERE id=1;
then the two name combination of that contact shall be inserted into 'contact_names' (for further handling of these names). The table will be cleared regularily after handling the removed names.
You have one row with two columns, but you want two rows with one column.
In the general case, this can be done with a common table expression and a compound query:
WITH TwoColumns(a, b) AS (
SELECT a, b FROM ... -- the original two-column query
)
INSERT INTO ...(x)
SELECT a FROM TwoColumns
UNION ALL
SELECT b FROM TwoColumns;
In this case, we don't need so many subqueries and can simplify a little:
WITH gs(gName, sName) AS (
SELECT g.name,
s.name
FROM names AS g,
names AS s
WHERE g.id = 2
AND s.id = 1
)
INSERT INTO contact_names(fullname)
SELECT gName || ' ' || sName FROM gs
UNION ALL
SELECT sName || ' ' || gName FROM gs;

Simple Split function in SQL Server 2012 with explanation pls

I have two tables Procedures and ProcedureTypes.
Procedures has a column Type which is a varchar with the values (1, 2), (3, 4), (4, 5) etc...
ProcedureType has a primary key 'ID' 1 to 9.
ID Description
1 Drug
2 Other-Drug
etc...
ID is an integer value and Type is varchar value.
Now I need to join these two tables to show the values
ID in the Procedures table
ProcedureType in the Procedures table
Description in the ProceduresType table with the value separated by a "-".
For example if he value in Type is (1,2) the new table after join should show values in the description like (Drug-Other Drug)
I have used this query bot to no avail
SELECT * FROM dbo.[Split]((select RequestType from GPsProcedures), ',')
Can anyone tell me how to do it and why the above query is not working
with Procedures as (
select 1 as ID, '1,2,3' as Typ
),
ProcedureTypes as (
select 1 as TypeID, 'Drug' as Name
union select 2 , 'Other-Drug'
union select 3 , 'Test 3'
)
/*Get one extra column of type xml*/
,Procedures_xml as (
select id,CONVERT(xml,' <root> <s>' + REPLACE(Typ,',','</s> <s>') + '</s> </root> ') as Typ_xml
from Procedures
)
/*Convert the field string to multiple rows then join to procedure types*/
, Procdure_With_Type as (
select ID,T.c.value('.','varchar(20)') as TypeID,
ProcedureTypes.Name
from Procedures_xml
CROSS APPLY Typ_xml.nodes('/root/s') T(c)
INNER JOIN ProcedureTypes ON T.c.value('.','varchar(20)') = ProcedureTypes.TypeID
)
/*Finally, group the procedures type names by procedure id*/
select id,
STUFF((
SELECT ', ' + [Name]
FROM Procdure_With_Type inn
WHERE (Procdure_With_Type.ID = inn.ID)
FOR XML PATH(''),TYPE).value('(./text())[1]','VARCHAR(MAX)')
,1,2,'') AS NameValues
from Procdure_With_Type
group by ID
You can't have a select statement as a parameter for a function, so instead of this:
SELECT * FROM dbo.[Split]((select RequestType from GPsProcedures), ',')
Use this:
select S.*
from GPsProcedures P
cross apply dbo.[Split](P.RequestType, ',') S

Result in Pivot Structure

I am sending you the details that i am in mess.
below I am describing.
Original Table Structure.
ID Date TimeLogged(Hrs) UserName
1 10/8/2012 5.50 Bubai
2 11/8/2012 2.30 Bubai
3 10/8/2012 3.30 Bhanu
4 11/8/2012 7.30 Bhanu
I want result like below. User Name should be dynamic. May be lot of
users. User name will come from Database table.
I want to show details in Gridview(Front End).explain broadly as I am very new in development.
Date Bubai Bhanu Total
10/8/2012 5.30 3 8. 30
11/8/2012 2.30 7.30 10
Total 8 10.30 18.30
You can use a PIVOT for this, either a Static or Dynamic. You can place this code in a stored procedure and populate your datagrid with it.
Static Pivot (See SQL Fiddle with Demo) This means you will hard code all values:
select convert(char(10), dt, 101), [Bubai], [Bhanu], ([Bubai] + [Bhanu]) total
from
(
select dt, timelogged, username
from test
)x
pivot
(
sum(timelogged)
for username in ([Bubai], [Bhanu])
)p
union all
select 'total', sum([Bubai]), sum([Bhanu]), sum([Bubai] +[Bhanu])
from
(
select dt, timelogged, username
from test
)x
pivot
(
sum(timelogged)
for username in ([Bubai], [Bhanu])
)p
Dynamic Pivot (See SQL Fiddle with Demo), this will get the list of fields to transform at run-time:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX),
#totalCol AS NVARCHAR(MAX),
#totalRow AS NVARCHAR(MAX)
SET #cols = STUFF((SELECT distinct ',' + QUOTENAME(c.username)
FROM test c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #totalCol = STUFF((SELECT distinct '+' + QUOTENAME(c.username)
FROM test c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #totalRow = STUFF((SELECT distinct ',Sum(' + QUOTENAME(c.username) + ')'
FROM test c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT convert(char(10), dt, 101), ' + #cols + ', '+#totalCol +' total from
(
select dt, timelogged, username
from test
) x
pivot
(
sum(timelogged)
for username in (' + #cols + ')
) p
union all
select ''total'', '+ #totalRow +', sum('+#totalCol+')
from
(
select dt, timelogged, username
from test
)x
pivot
(
sum(timelogged)
for username in (' + #cols + ')
)p'
execute(#query)
Both of these will produce the same results.
#NikolaMarkovinović is right, you should get the results you need using a pivot query, the problem is you have to know the values in the column you want to pivot
SELECT Date , [Bunbai] , [Bhanu] , ..., /* This names have to be known, the same as in the IN part of the PIVOT */
/* You can even do this */
[Bunbai]+[Bhanu] AS Total
FROM ( <SELECT query that produces the data> ) AS T
PIVOT ( SUM( TimeLoggedHours ) FOR UserName
IN ( [Bunbai] , [Bhanu] , ... )
/* You can't write some subquery inside the IN, columns names have to be known */
) AS pvt
, you will need to write a Dinamic Query Method in you code to, first get the names of the columns, then add them in the headers of the query and the IN part of the PIVOT.
To add the totals at the bottom just write the same query but in the query that produces the data, instead of the date select 'Total' and use UNION ALL
Hope this helps.

passing list of name/value pairs to stored procedure

I have a name/value pair in a List<T> and needing to find the best way to pass these to a stored procedure.
Id Name
1 abc
2 bbc
3 cnn
....
...
What is the best way to accomplish this?
One way to handle this in SQL Server 2005 (prior to the availability of table valued parameters) was to pass a delimited list and use a Split function. If you are using a two-column array, you would want to use two different delimiters:
Declare #Values varchar(max)
Set #Values = '1,abc|2,bbc|3,cnn'
With SplitItems As
(
Select S.Value As [Key]
, S2.Value
, Row_Number() Over ( Partition By S.Position Order By S2.Position ) As ElementNum
From dbo.Split(#Values,'|') As S
Outer Apply dbo.Split(S.Value, ',') As S2
)
Select [Key]
, Min( Case When S.ElementNum = 1 Then S.Value End ) As ListKey
, Min( Case When S.ElementNum = 2 Then S.Value End ) As ListValue
From SplitItems As S
Group By [Key]
Create Function [dbo].[Split]
(
#DelimitedList nvarchar(max)
, #Delimiter nvarchar(2) = ','
)
RETURNS TABLE
AS
RETURN
(
With CorrectedList As
(
Select Case When Left(#DelimitedList, Len(#Delimiter)) <> #Delimiter Then #Delimiter Else '' End
+ #DelimitedList
+ Case When Right(#DelimitedList, Len(#Delimiter)) <> #Delimiter Then #Delimiter Else '' End
As List
, Len(#Delimiter) As DelimiterLen
)
, Numbers As
(
Select Row_Number() Over ( Order By c1.object_id ) As Value
From sys.columns As c1
Cross Join sys.columns As c2
)
Select CharIndex(#Delimiter, CL.list, N.Value) + CL.DelimiterLen As Position
, Substring (
CL.List
, CharIndex(#Delimiter, CL.list, N.Value) + CL.DelimiterLen
, CharIndex(#Delimiter, CL.list, N.Value + 1)
- ( CharIndex(#Delimiter, CL.list, N.Value) + CL.DelimiterLen )
) As Value
From CorrectedList As CL
Cross Join Numbers As N
Where N.Value < Len(CL.List)
And Substring(CL.List, N.Value, CL.DelimiterLen) = #Delimiter
)
Another way to handle this without table-valued parameters is to pass Xml as an nvarchar(max):
Declare #Values nvarchar(max)
Set #Values = '<root><Item Key="1" Value="abc"/>
<Item Key="2" Value="bbc"/>
<Item Key="3" Value="cnn"/></root>'
Declare #docHandle int
exec sp_xml_preparedocument #docHandle output, #Values
Select *
From OpenXml(#docHandle, N'/root/Item', 1)
With( [Key] int, Value varchar(10) )
Take a look at Arrays and Lists in SQL Server 2008 to get some ideas
SQL Server 2008 also supports this multi row values syntax
create table #bla (id int, somename varchar(50))
insert #bla values(1,'test1'),(2,'Test2')
select * from #bla
i endup using foreach <insert>
This could done through three ways.
User Defined Table Type
Json Object Parsing
XML Parsing
I tried with the first option and passed a list of pairs in User Defined Table Type. This works for me. I am posting here, it might help someone else.
The first challenge for me was to pass the list of key value pair data structure and second to loop through the list and insert the record in a table.
Step 1 : Create a User Defined Table Type. I have created with a name 'TypeMetadata'. As it is custom type, I created two attributes of type nvarchar. You can create one of type integer and second of type nvarchar.
-- Type: metadata ---
IF EXISTS(SELECT * FROM SYS.TYPES WHERE NAME = 'TypeMetadata')
DROP TYPE TypeMetadata
GO
CREATE TYPE TypeMetadata AS TABLE (
mkey nvarchar (50),
mvalue nvarchar (50)
);
GO
Step 2 : Then I created a stored procedure with name 'createfiled'
-- Procedure: createtext --
CREATE PROCEDURE [dbo].[createfield]
#name nvarchar(50),
#text nvarchar(50),
#order int,
#type nvarchar(50),
#column_id int ,
#tid int,
#metadataList TypeMetadata readonly
AS
BEGIN
--loop through metadata and insert records --
DECLARE #mkey nvarchar(max);
DECLARE #mvalue nvarchar(max);
DECLARE mCursor CURSOR LOCAL FAST_FORWARD
FOR
SELECT mkey, mvalue
FROM #metadataList;
OPEN mCursor;
FETCH NEXT FROM mCursor INTO #mkey, #mvalue; -- Initial fetch attempt
WHILE ##FETCH_STATUS = 0
BEGIN
INSERT INTO template_field_metadata (name, value, template_field_id, isProperty) values (#mkey, #mvalue, 1, 0)
PRINT 'A new metadata created with id : ' + cast(SCOPE_IDENTITY() as nvarchar);
FETCH NEXT FROM mCursor INTO #mkey, #mvalue; -- Attempt to fetch next row from cursor
END;
CLOSE mCursor;
DEALLOCATE mCursor;
END
GO
Step 3: finally I executed the stored procedure like;
DECLARE #metadataToInsert TypeMetadata;
INSERT INTO #metadataToInsert VALUES ('value', 'callVariable2');
INSERT INTO #metadataToInsert VALUES ('maxlength', '30');
DECLARE #fid INT;
EXEC [dbo].[createfield] #name = 'prefagent', #text = 'Pref Agent', #order = 1 , #type= 'prefagent', #column_id = 0, #tid = 49, #metadataList =#metadataToInsert;
