Simpler one. It's like PADL.

SELECT REPLICATE('0', 10-PATINDEX('%[^0-9]%', @StreetNumber + 'A')) + @StreetNumber

>I have a StreetNumber column that is CHAR(8). It needs to be character, because you can have alpha in a street number, ie: 102A First St. The problem is that I need to provide the capability to search on a range of street numbers.

>Simply using

>WHERE StreetNumber >= '300' and StreetNumber < '500'

>won't work, because of the fact that it returns numbers like 35, 42, etc.

>But, because of the possibility of alpha characters, I cannot use CAST or CONVERT to compare numerically. I thought the answer would be to pad with leading zeros and continue to do a string comparison ... but how does one do that with T-SQL? There is no PADL statement.
