T-SQL:  Leading Zeroes

Hello:

Below is a T-SQL field that I programmed called "ytdhours".

As you can see, it needs to be a total of six digits--four to the left of the decimal place and two to the right.

But, I need leading zeroes to dynamically appear to the left of the decimal.  For example, the result that was derived from running this was "429.75".  I need the result to be "0429.75".  Or, if the result had been "29.75", I would need it to actually be "0029.75".

How can I accomplish this?

Thanks!

Try the following:

SELECT RIGHT('0000'+ CONVERT(VARCHAR, xxxx ),4)

Replacing the 'xxxx' with your query above.

>I need the result to be "0429.75".
Then you need to display it as a character value, as no numeric data types support leading zeros.   Copy-paste the below T-SQL into your SSMS, execute it to verify it's what you need, then modify to meet your needs.

Declare @val numeric(7,2) = 429.75

SELECT RIGHT('0000000' + CAST(@val as varchar(7)), 7)

Thank you, for both responses!

@JEaston:  That worked!  I had to use 7 zeroes and a "7" at the end.  I'm not sure why that worked instead of "6".  But, it did.

Thank you!
