ERROR: Teradata row not delivered (trget): Numeric overflow occurred during computation.
I have ~300 variables in this data, at least one of them is causing this error. Without pulling one by one, or something like that, how can I identify which variable is the one causing this problem?
It's a teradata database, being read with proc sql in EG 9.4

Examine the variables in the Teradata source for characteristics that indicate large or small values like DOUBLE precision, extended precision or some such (I don't speak Teradata).
You apparently are doing something with a computation. Look for computations involving any of those variables. Perhaps either use pass through code an execute in Teradata then move the results to SAS or move the data to SAS prior to the computations.

The surprising thing to me was that simple counts can cause that error, depending on whether you are using TERADATA or ANSI mode.
We needed to use explicit passthru and cast the count as BIGINT, or better for working with SAS as FLOAT.
proc sql ; connect .... ; select * from connection to teradata (select cast(count(*) as float) as nobs from mydb.mytable ); quit;
