| I have three columns I'd like to concat in a fourth column.col1 is a varchar(10)col2 is an intcol3 is the pk(int)When I use this formula:([col1] + '' + [col2] + '' + [col3])it changes the column to an int, and it won't let me use the two Letter code in col1. And it won't let me change the type to a varchar. I've tried deleting the col and trying again, but no dice. Even ditched the table and still no luck.any ideas? |

| How did you try to change the datatype? Did you use CAST or CONVERT? That should work.e4 d5 xd5 Nf6 |

| Bonus round - the last column I have is an incrementing value, but I'd like to have the concatted value have the same length regardless. Is there a way to put an if statement that looks at the length of the pk and tacks on 0's?col1 - PScol2 - 07col3 - 1concat value is PS070001 Thought of using an IF, but I'm wondering if I can in SQL formula |
