Datatype missmatch between two tables

I want to do an inner join from the TRN_FACT table PST50_ACCT_NUM to the ACCT_NBR in the T_SESS table.  At issue is that the PST50_ACCT_NUM is numeric and the ACCT_NBR is char.  Currently I bring in both datasets separately however both are quite huge and I get timeout errors.

In the TRN_FACT table I defined the PST50_ACCT_NUM as a character.(put(PST50_ACCT_NUM,z17.) as pst50_acct_nbr)

Is there a way to define and use it to join the T_Sess table within the same pass through routine.

Since your using SQL Passthrough convert it within the passthrough and do the join here. There is the CAST() and CONVERT() functions so you can modify whichever field you choose. If you have example's of the fields it would be easier to show you.

So you would basically do:

join b on a.charfield = cast(b.numericvar as varchar(17));
