Question

Comparing two sql values that are almost the same.

I know this is simple but I can’t think how to do it

I want to do a join or a “select where = ” on two values in two tables.
Problem is one table has a filname with an extension and the other has the filename without the extension. I want to ignore the extension and just do my compare.
How would I do that?

I have something simple like this.

select thing1, thing2
where tableName.filename=tableName2.fileName
from tableName,tableName2

Answer 1

Please don’t use a multi-part from clause. Use the join syntax instead.

Assuming tableName has the extension and tableName2 does not:

select
    thing1,
    thing2

from tableName tn

join tableName2 tn2 on tn.fileName like tn2.fileName + '.%'
