I have a Procedure which returns MobileAreaCode+Mobile if they are not null
I just want to add to it support for empty strings as well I tried(without the handle for empty string it works)
ALTER PROCEDURE PROC_NAME
#Identification INT
AS
BEGIN
SELECT
CASE WHEN MobileAreaCode is NOT NULL OR Mobile is NOT NULL
OR MobileAreaCode<>'' OR Mobile<>''
THEN
MobileAreaCode+Mobile
END
FROM
TABLE_NAME
WHERE
id = 123456789
END
GO
which doesn't work and results the following error:
Incorrect syntax near the keyword 'FROM'.
You can use Use NULLIF (Transact-SQL).
select nullif(MobileAreaCode, '')+nullif(Mobile, '') as MobileAreaCodeMobile
from YourTable
SQL Fiddle
ALTER PROCEDURE PROC_NAME
#Identification INT
AS
BEGIN
SELECT
CASE WHEN (MobileAreaCode is NOT NULL) AND (Mobile is NOT NULL)
AND (len(MobileAreaCode)>0) AND (len(Mobile)>0)
THEN
MobileAreaCode+Mobile
END
FROM
TABLE_NAME
WHERE
id = 123456789
END
GO

Need help in filtering bad xml data from the column which is blob format. Using the below query to achieve this and facing the below error.
Query:
SELECT COLUMN1 AS NAME, CASE WHEN COLUMN2 = '' THEN XMLCAST( XMLQUERY( '$file/*:value' PASSING XMLPARSE( DOCUMENT TABLE."DATA" ) AS "file" ) AS VARCHAR(10)) ELSE COLUMN2 END AS INFO FROM TABLE

I am creating a procedure for a split string in MariaDB but it is giving error

In MariaDB/MySQL statements are terminated with semicolons ;. Add semicolon after each statement.
You might also want to reconsider to use temporary table instead of normal table as you might run into trouble when multiple users are running the procedure at same time.
Quick question on Coalesce:
clw.ClawbackPercent = Coalesce(#ClawbackPercent, clw.ClawbackPercent)
Lets say for column 'ClawbackPercent' I have a value of 100.
If I execute a proc and set parameter #ClawbackPercent to have the value NULL, it keeps the value 100 in the row for that column which is great.
However, if I want to set 100 to actually be NULL, what do I need to write in the exec proc statement or what do I need to add in the Coalesce statement?
Thank you
It sounds like you want 100 to be the Default value of a stored proc parameter, not necessarily to replace all NULLs with this value. If this is the case, you don't want a COALESCE but you do need to provide a default value for the parameter on the proc definition.
e.g.
CREATE PROC dbo.MyProc (
#MyParam INT = 100
)
AS
-- My code here
If somebody executes this proc without specifying a value for #MyParam, the default of 100 will be assigned. If they explicitly specify #MyParam = NULL then NULL will be assigned..
Then probably you should not use coalesce, instead you can use case statement as below:
clw.ClawbackPercent = CASE WHEN #ClawbackPercent = 100
THEN NULL
ELSE
#ClawbackPercent END
in the select statement
You have to write in the following way:
CREATE PROCEDURE sp_test(
#ClawbackPercent VARCHAR(30)
) AS
BEGIN
SELECT COALESCE(#ClawbackPercent, '100')
END
--call as below and if you want to return second value then, EXEC sp_test NULL
--if your second, thirds... parameters are in INTEGER then simply CAST to VARCHAR
EXEC sp_test 'NULL'
My Table Contains
Id(int) name(nvarchar(300)) path(nvarchar(3000))

my Query:
select * from tbl1 where Path = 'વસૂલાત/SubUnit/!##$%^&*()_+{}|:"<>?,.;''[]\-='
I am Getting Empty Table.backslash and single quotes are used.
Use N prefix in your search string something like this...
select * from tbl1
where Path = N'વસૂલાત/SubUnit/!##$%^&*()_+{}|:"<>?,.;''[]\-='
Because you have these unicode characters in your strings, you need to tell sql server explicitly that string may contain some unicode character by prefixing it with N.
Same is true when you are inserting, updating unicode data in sql server.

I've created a table valued function:
CREATE FUNCTION TestFunction
(
#username VARCHAR(80)
)
RETURNS TABLE
AS
RETURN
(
SELECT 0 AS TestValue
)
Then try to call it as so:
SELECT TestValue
FROM dbo.TestFunction(SYSTEM_USER)
but get the error:
Incorrect syntax near the keyword 'SYSTEM_USER'
I've even tried making this a table valued function which is not inline, but I get the same error.
Am I missing something? Why am I getting this error?
On my 2k8 server I can only reproduce that with SQL Server 2000 (80) Compatibility level set, check the level of your 2005 database.
Meantime you can;
declare #su varchar(30) = SYSTEM_USER
select * from dbo.TestFunction(#su)
