Hi,

Is it possible to include an IF statement into a select query??

I am trying to include "IF (CONVERT(VARCHAR(10),GETDATE(),108) > '09:00:00')" into a select query but am receving several errors when I do.

Thanks
SELECT  INCI.INCIDENT_CODE,

		INCI.INCIDENT_TITLE,

		INCI.INCIDENT_MESSAGE,

		U.USER_NAME  AS OWNER,

		C.FIRST_NAME + ' ' + C.LAST_NAME AS CONTACT_REQUESTER,

		L1.LIST_VALUE AS INCIDENT_STATUS,

		L2.LIST_VALUE AS INCIDEND_PRIORITY,

		INCI.CREATE_DATETIME,
 

--IF (CONVERT(VARCHAR(10),GETDATE(),108) > '09:00:00')

	

		

		--CASE STATEMENT TO IDENTIFY SLA FIX DATETIME COLOUR

		CASE 	

		WHEN DATEDIFF(MI, CONVERT(DATETIME, GETDATE(), 103), CONVERT(DATETIME, INCIS.FIELD_VALUE, 103) ) > (SLA.SLA_TIME / 2) THEN (SELECT LIST_VALUE FROM TBL_LIST WHERE LIST_CODE = 'LIST00000000361')

		WHEN DATEDIFF(MI, CONVERT(DATETIME, GETDATE(), 103), CONVERT(DATETIME, INCIS.FIELD_VALUE, 103) ) <= (SLA.SLA_TIME / 2) AND DATEDIFF(MI, CONVERT(DATETIME, GETDATE(), 103), CONVERT(DATETIME, INCIS.FIELD_VALUE, 103) ) > (SLA.SLA_TIME / 3) THEN (SELECT LIST_VALUE FROM TBL_LIST WHERE LIST_CODE = 'LIST00000000362')

what do you mean if?
what are you trying to achieve?
it is not possible to determine using an if the number of columns that will be selected, since each row must have the exact same columns

you can use a case statement in order to decide if you wish to return a value or just a null for a certain column

you cannot place the IF inside the query but you can do :
DECLARE @VAR VARCHAR(10)

SET @Var=CONVERT(VARCHAR(10),GETDATE(),108)

IF @Var>''09:00:00'
SELECT ..........
ELSE
SELECT .........

WHat are you trying to achieve ?

Looking at your example it would be something for monitoring SLA's; I do something similar with our Support Centre; but I use in the where clause:

DATEPART(HH, YourField) BETWEEN '8' AND '18'

Ok, basically I only want to use the two case statements if the current time is greater than 09:00:00.

If is before 09:00:00 then I dont want the two case statements to run

Hope this helps

The example above will help as you're saying your criteria is between set hours.

This IF too u can avoid... by bringing the condition in where clause
