Hi! I am trying to do an inner join of two tables using a char(3) key. The field I am joining by contains integers with sometimes leading zeros.
If it is a char(3) field it contains characters, not integers.
The inner join works when the field is a full 3 character field, with for example 566, but when it starts with a 0, it does not work anymore. Why is this?
If you are joining a CHAR(3) field to a INT(3) field, the INT(3) becomes a "CHAR(3)' for the join.
'013' is not equal to '13'.
Try casting the CHAR(3) to an int.
I would appreciate some help, thanx. /Camilla
