RE: joining 3 files

What about creating an SQL View which joins all 3 tables and then using this
view in Query/400

I dont believe WRKQRY has a way of joining fields having different types.
Did you try SQL? Not sure if SQL CAST AS will fix your issue, but its worth
a try.

Hi,

I m trying to match records of 3 files s using WRKQRY but the problem
is happening for the data type in second file for example


Field TEST Field
T01.fld1 EQ T02.fld2

TO1.fld2 EQ T03.fld3


So after declaring primary and two other files in this WRKQRY and
then specifying how to join them ( here fld2 and fld3 fields of file2
and file3 respectively just for example ) giving me error ' Field used
to test field T01.fld1 must be numeric' and that
T02.fld2 is getting highlighted in green color and at bottom of this
screen getting this mentioned error.

If the field in file2 ,fld2 is defined as character and field1 in
file1 is defined as Decimal then what could be done to get the
matching results from these fields and files in this WRKQRY?

Also can the same matching records based on above conditions be
obtained ( where this error should not come for data types of the
fields like here in WRKQRY Example) using a single SQL query,if yes then

how?

Thanks
