With the below query I generate a datable whose diagram is as below:-
SELECT *
FROM (SELECT DISTINCT sv.mkey, vehicle_no,
CASE
WHEN sv.audit_flag = 'N'
THEN 'REJECTED'
ELSE 'PENDING APPROVAL'
END isnullcheck,
TO_CHAR (date_in,
'dd-MM-yyyy'
)
|| ' & '
|| time_in vehicleindate_time,
TO_CHAR (date_out,
'dd-MM-yyyy'
)
|| ' & '
|| time_out vehicleoutdate_time,
gate_no_in || ' & ' || gate_no_out ingate_outgateno,
remark_in remarkin, NULL receipt_no, date_in,
CASE
WHEN sv.audit_flag = 'N'
THEN 'Y'
ELSE 'N'
END hod
FROM xxcus.xxgid_audit_entry sv
WHERE sv.project_id = '1365'
AND (sv.audit_flag IS NULL OR sv.audit_flag = 'N')
UNION
SELECT NULL, NULL, 'PENDING APPROVAL', NULL, 'PENDING APPROVAL',
NULL, NULL, NULL, NULL, NULL
FROM DUAL
UNION
SELECT NULL, NULL, 'REJECTED', NULL, 'REJECTED', NULL, NULL, NULL,
NULL, NULL
FROM DUAL) qq
ORDER BY isnullcheck DESC
the generated datable is as below
[![Datatable][1]][1]
Now what, I want is.
The query will fetch result into two headings
ie. 1. REJECTED or 2. PENDING APPROVAL
but what happening here is it is going other than both the heading also. It should not go.

Also see the html of grid
How to make that under two headings ?? is there any issue with query ?
Order by something else as well, and used NULLS FIRST on that:
ORDER BY isnullcheck DESC, mkey NULLS FIRST
V_SQL4 := 'UPDATE EMP_TABLE m
Set m.name = mft.name,
m.age = mft.age,
m.dept = mft.dept,
Where m.id = mft.id and
(m.name != mft.name Or
m.age != mft.age Or
m.dept != mft.dept )';
DBMS_OUTPUT.PUT_LINE(V_SQL4);
EXECUTE IMMEDIATE V_SQL4;
How and where to declare the temporary table EMP_TMPas mft in the statement?
If i look into the requirement i dont see requirment of PL/SQL in
this. A better approach woould be using Merge. I have illuistrated an
example below. If Dynamic SQL is not hard and bound you can use this
too. Let me know if this helps.
MERGE INTO EMP_TABLE m USING EMP_TMP mft
ON (m.id = mft.id AND (m.name != mft.name OR m.age != mft.age OR m.dept != mft.dept))
WHEN MATCHED THEN
UPDATE SET
m.name = mft.name,
m.age = mft.age,
m.dept = mft.dept;
This SO post has an answer to a similar question.
In your case, the query would transform as below
V_SQL4 := 'UPDATE EMP_TABLE m
SET (name, age, dept) = (SELECT mft.name
,mft.age
,mft.dept
FROM EMP_TMP mft
WHERE m.id = mft.id
AND m.name != mft.name Or
AND m.age != mft.age Or
AND m.dept != mft.dept
)
WHERE EXISTS (
SELECT 1
FROM EMP_TMP mft
WHERE m.id = mft.id
)';
I have a checkboxlist. The selected (checked) items are stored in List<string> selected.
For example, value selected is monday,tuesday,thursday out of 7 days
I am converting List<> to a comma-separated string, i.e.
string a= "monday,tuesday,thursday"
Now, I am passing this value to a stored procedure as a string. I want to fire query like:
Select *
from tblx
where days = 'Monday' or days = 'Tuesday' or days = 'Thursday'`
My question is: how to separate string in the stored procedure?
If you pass the comma separated (any separator) string to store procedure and use in query so must need to spit that string and then you will use it.
Below have example:
DECLARE #str VARCHAR(500) = 'monday,tuesday,thursday'
CREATE TABLE #Temp (tDay VARCHAR(100))
WHILE LEN(#str) > 0
BEGIN
DECLARE #TDay VARCHAR(100)
IF CHARINDEX(',',#str) > 0
SET #TDay = SUBSTRING(#str,0,CHARINDEX(',',#str))
ELSE
BEGIN
SET #TDay = #str
SET #str = ''
END
INSERT INTO #Temp VALUES (#TDay)
SET #str = REPLACE(#str,#TDay + ',' , '')
END
SELECT *
FROM tblx
WHERE days IN (SELECT tDay FROM #Temp)
Try this:
CREATE FUNCTION [dbo].[ufnSplit] (#string NVARCHAR(MAX))
RETURNS #parsedString TABLE (id NVARCHAR(MAX))
AS
BEGIN
DECLARE #separator NCHAR(1)
SET #separator=','
DECLARE #position int
SET #position = 1
SET #string = #string + #separator
WHILE charindex(#separator,#string,#position) <> 0
BEGIN
INSERT into #parsedString
SELECT substring(#string, #position, charindex(#separator,#string,#position) - #position)
SET #position = charindex(#separator,#string,#position) + 1
END
RETURN
END
Then use this function,
Select *
from tblx
where days IN (SELECT id FROM [dbo].[ufnSplit]('monday,tuesday,thursday'))
try this
CREATE FUNCTION Split
(
#delimited nvarchar(max),
#delimiter nvarchar(100)
) RETURNS #t TABLE
(
-- Id column can be commented out, not required for sql splitting string
id int identity(1,1), -- I use this column for numbering splitted parts
val nvarchar(max)
)
AS
BEGIN
declare #xml xml
set #xml = N'<root><r>' + replace(#delimited,#delimiter,'</r><r>') + '</r></root>'
insert into #t(val)
select
r.value('.','varchar(max)') as item
from #xml.nodes('//root/r') as records(r)
RETURN
END
GO
usage:
select * from tblx where days in (select val from dbo.split('monday,tuesday,thursday',','))
I think you want this
SELECT * FROM tblx where days in ('Monday','Tuesday','Thursday')
you can get it like this:
var a = "monday,tuesday,thursday";
var sql = string.Format("Select * from tblx where days IN ('{0}')", string.Join("','",a.Split(new[] {','})));
I face the same problem, and i try all the way but not get expected solution. Finally i did like follow. Try it hope it will work...
create Function [dbo].[Split]
(
#RowData NVARCHAR(MAX),
#SplitOn NVARCHAR(5)
)
RETURNS #RtnValue TABLE
(
Id INT IDENTITY(1,1),
Data NVARCHAR(100)
)
AS
BEGIN
DECLARE #Cnt INT
SET #Cnt = 1
WHILE (Charindex(#SplitOn,#RowData)>0)
BEGIN
INSERT INTO #RtnValue (data)
SELECT Data = ltrim(rtrim(Substring(#RowData,1,Charindex(#SplitOn,#RowData)-1)))
SET #RowData = Substring(#RowData,Charindex(#SplitOn,#RowData)+1,len(#RowData))
SET #Cnt = #Cnt + 1
END
INSERT INTO #RtnValue (data)
SELECT Data = ltrim(rtrim(#RowData))
RETURN
END
And in the store procedure put the code like that.
select #ActualTarget= count(*) from UpdateVisitDetails where CreatedBy IN (SELECT [DATA] FROM [dbo].[Split](#AllDATS,',' ))
I have same problem. I tried this.. and this was properly run
ALTER FUNCTION [dbo].[Split]
(
#List varchar(max),
#SplitOn nvarchar(5)
)
RETURNS #RtnValue table
(
Id int identity(1,1),
Value nvarchar(max)
)
AS
BEGIN
IF (len(#List) <=0)
Begin
Return
End
While (Charindex(#SplitOn,#List)>0)
Begin
Insert Into #RtnValue (value)
Select
Value = ltrim(rtrim(Substring(#List,1,Charindex(#SplitOn,#List)-1)))
Set #List = Substring(#List,Charindex(#SplitOn,#List)+len(#SplitOn),len(#List))
End
Insert Into #RtnValue (Value)
Select Value = ltrim(rtrim(#List))
Return
END
Run :
SELECT * FROM dbo.Split('Apple,Banana,Mango',',')
Output:
I have 2 queries and calling a function 2 times I need call the function one time only based on msg_sys_no count and msg_trans_type.
please find the queries mentioned below and provide me the solution for merging into single.
SELECT COUNT(DISTINCT b1.msg_sys_no) INTO A
FROM tra_message b1
WHERE TO_CHAR(b1.msg_when_created,'YYYY-MM-DD') = in_start_date
AND b1.msg_service_provider = in_svc_provider
AND b1.msg_trans_type = 'TRADE1'
AND get_transaction_status_func(b1.msg_sys_no, b1.msg_trans_type) = 'S';
SELECT COUNT(DISTINCT b1.msg_sys_no) INTO B
FROM tra_message b1
WHERE TO_CHAR(b1.msg_when_created,'YYYY-MM-DD') = in_start_date
AND b1.msg_service_provider = in_svc_provider
AND b1.msg_trans_type = 'TRADE2'
AND get_transaction_status_func(b1.msg_sys_no, b1.msg_trans_type) = 'S';
What about something like this:
WITH tra_data
AS (SELECT *
FROM tra_message
WHERE TO_CHAR (msg_when_created, 'YYYY-MM-DD') = in_start_date
AND msg_service_provider = in_svc_provider
AND get_transaction_status_func (msg_sys_no, msg_trans_type) =
'S')
SELECT COUNT (*)
FROM tra_data
WHERE msg_trans_type = 'TRADE1'
UNION
SELECT COUNT (*)
FROM tra_data
WHERE msg_trans_type = 'TRADE2'
The problem is your AND b1.msg_trans_type IN ('TRADE1','TRADE2') condition.
Try something like this:
select COUNT(DISTINCT a) TRADE1,
COUNT(DISTINCT b) TRADE2
into A,B
from (
select case when b1.msg_trans_type = 'TRADE1'
then b1.msg_sys_no
else null end as a,
case when b1.msg_trans_type = 'TRADE2'
then b1.msg_sys_no
else null end as b
FROM tra_message b1
WHERE TO_CHAR(b1.msg_when_created,'YYYY-MM-DD') = in_start_date
AND b1.msg_service_provider = in_svc_provider
AND b1.msg_trans_type IN ('TRADE1','TRADE2')
AND get_transaction_status_func(b1.msg_sys_no, b1.msg_trans_type) = 'S'
);
Ok, I have a complex recursion problem. I want to get a dependecy installation sequence of all of my objcts (all_objects table) in my Oracle 11g database.
First I have created a view holding all dependencies
create or replace
view REALLY_ALL_DEPENDENCIES as
select *
from ALL_DEPENDENCIES
union
select owner, index_name, 'INDEX', table_owner, table_name, table_type, null, null
from all_indexes
union
select p.owner, p.table_name, 'TABLE', f.owner, f.table_name, 'TABLE', null, null
from all_constraints p
join all_constraints f
on F.R_CONSTRAINT_NAME = P.CONSTRAINT_NAME
and F.CONSTRAINT_TYPE = 'R'
and p.constraint_type='P'
;
/
EDIT
I have tried do concate all dependencies by using this function:
create
or replace
function dependency(
i_name varchar2
,i_type varchar2
,i_owner varchar2
,i_level number := 0
,i_token clob := ' ') return clob
is
l_token clob := i_token;
l_exist number := 0;
begin
select count(*) into l_exist
from all_objects
where object_name = i_name
and object_type = i_type
and owner = i_owner;
if l_exist > 0 then
l_token := l_token || ';' || i_level || ';' ||
i_name || ':' || i_type || ':' || i_owner;
else
-- if not exist function recursion is finished
return l_token;
end if;
for tupl in (
select distinct
referenced_name
,referenced_type
,referenced_owner
from REALLY_ALL_DEPENDENCIES
where name = i_name
and type = i_type
and owner = i_owner
)
loop
-- if cyclic dependency stop and shout!
if i_token like '%' || tupl.referenced_name || ':' || tupl.referenced_type || ':' || tupl.referenced_owner || '%' then
select count(*) into l_exist
from REALLY_ALL_DEPENDENCIES
where name = tupl.referenced_name
and type = tupl.referenced_type
and owner = tupl.referenced_owner;
if l_exist > 0 then
return '!!!CYCLIC!!! (' || i_level || ';' || tupl.referenced_name || ':' || tupl.referenced_type || ':' || tupl.referenced_owner || '):' || l_token;
end if;
end if;
-- go into recursion
l_token := dependency(
tupl.referenced_name
,tupl.referenced_type
,i_owner /* I just want my own sources */
,i_level +1
,l_token);
end loop;
-- no cyclic condition and loop is finished
return l_token;
end;
/
And I can query through
select
object_name
,object_type
,owner
,to_char(dependency(object_name, object_type, owner)) as dependecy
from all_objects
where owner = 'SYSTEM'
;
Ok, maybe it is something like "cheating" but you can not do cyclic dependencies at creation time. So at least as a human beeing I am only able to create one object after another :-) And this sequence should be "reverse engineer able".
Now I am more interested in a solution than before ;-) And it is still about the tricky part ... "How can I select all soures from a schema orderd by its installation sequence (dependent objects list prior the using object)"?
It is just some kind of sorting problem, insn't it?
Usually you "cheat" by creating the objects in a particular order. For example, you might make sequences first (they have zero dependencies). Then you might do tables. After that, package specs, then package bodies, and so on.
Keep in mind that it is possible to have cyclic dependencies between packages, so there are cases where it will be impossible to satisfy all dependencies at creation anyway.
What's the business case here? Is there a real "problem" or just an exercise?
EDIT
The export tool we use exports objects in the following order:
Database Links
Sequences
Types
Tables
Views
Primary Keys
Indexes
Foreign Keys
Constraints
Triggers
Materialized Views
Materialized View Logs
Package Specs
Package Bodies
Procedures
Functions
At the end, we run the dbms_utility.compile_schema procedure to make sure everything is valid and no dependencies are missed. If you use other object types than these, I'm not sure where they'd go in this sequence.
Ok, I had some time to look at the job again and I want to share the results. Maybe anotherone comes across this thread searching for a solution. First of all I did the SQLs as SYS but I think you can do it in every schema using public synonyms.
The Procedure "exec obj_install_seq.make_install('SCOTT');" makes a clob containing a sql+ compatible sql file, assuming your sources are called "object_name.object_type.sql". Just spool it out.
