It's only for the hours? No minutes?
If so you can try this:
SELECT REPLICATE('0', 2-LEN(CAST(ColumName AS VARCHAR(4))))+CAST(ColumName AS VARCHAR(4)) + '00'
FROM TableName

If it is just the hours then:

select right('0' + cast((colname * 100) as nvarchar(2)), 4)

Open in new window


Basically multiply by 100 and prefix with a 0 and return the right 4 chars

Victor,

Yes it's only for the hours.  I'm using a stored procedure that uses:
SET @8hrfirstshiftstart = 7
SET @8hrfirstshiftend = 15
ect....

to find the start and end of shifts.   But I want to return the  7 or other values from the stored procedure to use as labels in crystal reports.

Like this...

0700 - 1500

Pawan,

Unfortunately that won't work for time values like

7    =    0700
1    =    0100

----
7000

(1 row(s) affected)


----
1900

(1 row(s) affected)


----
2300

(1 row(s) affected)


----
1000

So use this in your SP:
DECLARE @8hrfirstshiftstart INT = 7
DECLARE @8hrfirstshiftend INT = 15

SELECT REPLICATE('0', 2-LEN(CAST(@8hrfirstshiftstart AS VARCHAR(4))))+CAST(@8hrfirstshiftstart AS VARCHAR(4)) + '00 - '
     + REPLICATE('0', 2-LEN(CAST(@8hrfirstshiftend AS VARCHAR(4))))+CAST(@8hrfirstshiftend AS VARCHAR(4)) + '00' 

Open in new window


Result:
--------------------------------
0700 - 1500

(1 row(s) affected)
0
