Are the fields you are usiong varchar or char.

If they are char fields they will be getting padded if you do not have the
exact amount in the field. i.e.

char(5)

da will be padded da and 0s on the end up to the sizeof the char field.

If varchar then you will be ok.

If you do have a char then use the trim function to do the selects
