I have 2 xml documents that I need to reference in a nested FLWOR statement.
MJH source.xml
<data-set>
<record>
<table>CONTACT</table>
<column>AGGREGATE_REPORT</column>
<change>Dropped</change>
<logic>Related to agCenter</logic>
</record>
<record>
<table>QNR_DESIGN_TEMPLATE</table>
<column>LOGO1</column>
<change>Dropped</change>
<logic>Related to agCenter</logic>
</record>
</data-set>
This is the outer document and I need to extract the 'table' and 'column' values per row.
MVReport - a collection of report documents that contain SQL statements.
....
<xml-property name="queryText"><![CDATA[select v.*
from poi_visit_details_v v
where v.site_id=?
and v.std_code_id in ('15', 'TelephoneMonitoringVisit')
and to_char(v.actual_visit_date, 'yyyy-mm-dd') = substr(?, 0, 10)
and (reports_access_pk.site_access(v.SITE_ID, ?) = 'Y'
or reports_access_pk.superuser_access(?) = 'Y')
]]></xml-property>
<xml-property name="queryText"><![CDATA[select v.*
from poi_visit_details_v v
where v.site_id=?
and v.std_code_id in ('15', 'TelephoneMonitoringVisit')
and to_char(v.actual_visit_date, 'yyyy-mm-dd') = substr(?, 0, 10)
and (reports_access_pk.site_access(v.SITE_ID, ?) = 'Y'
or reports_access_pk.superuser_access(?) = 'Y')
]]></xml-property>
....
This collection is the inner loop where I need to find all SQL statements that contain the word "select" and the 'table', 'column' values returned from the outer loop.
Here is my xquery.
The issue I have is how to reference the outer 'table','column' values in the inner loop's "where ... and ..." clauses?
for $target in doc("H:\MJH source.xml")/data-set/record
let $tTable := $target/table
let $tColumn := $target/column
for $sql in collection("MVReport") //*:xml-property[#name = "queryText"]
where $sql contains text "select"
and $sql contains $tTable
and $sql contains $tColumn
let $report := base-uri()
return <report><name>{$sql/base-uri()}</name><sql>{$sql}</sql></report>
Thanks for your help.

So i have a query and it need to return a JSON object but the DISTINCT doesn't work no matter what I try. I've been trying a series of other tests and no matter what the 'WBS' always shows up with 3 or more duplicated columns. Anyone got any ideas?
I am working in Asp.net 6 MVC
PROCEDURE GET_BASELINE_RPT (in_WBS_LEVEL_ID IN NUMBER, in_FISCAL_YEAR IN VARCHAR2,
in_FISCAL_MONTH IN VARCHAR2, RET OUT CLOB) AS
BEGIN
WITH cte AS (
SELECT /*+MATERIALIZE*/ DISTINCT L.WBS_LEVEL_ID
FROM
WBS_LEVEL L
)
SELECT
JSON_ARRAYAGG (
JSON_OBJECT (
'WBS' VALUE L.WBS_LEVEL_NAME,
'Title' VALUE W.DESCRIPTION,
'Rev' VALUE B.REV_NUMBER,
'ScopeStatus' VALUE W.STATUS,
'BCP' VALUE CASE WHEN BC.FISCAL_YEAR = 0 THEN '' ELSE
SUBSTR(BC.FISCAL_YEAR,3,2)||'-'||LPAD(BC.BCP_FISCAL_ID, 3, '0') END,
'BCPApprovalDate' VALUE BC.APPROVAL_DATE,
'Manager' VALUE P1.NICK_NAME,
'ProjectControlManager' VALUE P2.NICK_NAME,
'ProjectControlEngineer' VALUE P3.NICK_NAME,
'FiscalYear' VALUE W.FISCAL_YEAR,
'FiscalMonth' VALUE W.FISCAL_MONTH,
'WBSNumber' VALUE L.WBS_LEVEL_ID
)RETURNING CLOB)
INTO RET
FROM WBS_LEVEL L
LEFT OUTER JOIN BASELINE_RPT B ON L.WBS_LEVEL_ID = B.WBS_LEVEL_ID
JOIN BCP BC ON BC.BCP_ID = B.BCP_ID
LEFT OUTER JOIN WBS_TREE_MOD W ON L.WBS_LEVEL_ID = W.WBS_LEVEL_ID
LEFT OUTER JOIN VW_SITEPEOPLE P1 ON W.WBS_MANAGER_SNUMBER = P1.SNUMBER
LEFT OUTER JOIN VW_SITEPEOPLE P2 ON W.PCM_SNUMBER = P2.SNUMBER
LEFT OUTER JOIN VW_SITEPEOPLE P3 ON W.PCE_SNUMBER = P3.SNUMBER
ORDER BY L.WBS_LEVEL_NAME, B.REV_NUMBER DESC;
END GET_BASELINE_RPT;
so it turns out I wasn't getting duplicates at all. There were differences in the data but there were so many columns that had the same data that I didn't notice the differences until another review. I will try to restart my query but to be honest I may just put in a filter in my C#.
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.
I would like to do this in teradata SQL/ MACRO or PROCEDURE :
CREATE MACRO insertloop ( val1 VARCHAR( 1000)) AS
(
sublist_i = ' SELECT sublist from table3 '
FOR sublist_i in sublist :
INSERT INTO table5
SELECT t.id, t.address, sum(t.amount)
FROM table2 AS t
WHERE
t.id in sublist_i
AND t.address = :val1
GROUP BY t.id t.address
);
Explanation:
table3 contains list of id (by block of 1000 id)
(12, 546, 999)
(45,789)
(970, 990, 123)
Main reason :
table2 is very huge (1 billion record).
A full join requires too much memory, we need
to create a table table3 containing disjoint list of id
and iterate on this list.
But, am not sure how to correct this MACRO to be make correct.
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
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;
