Daniel,

PMFJI, I do chain/batch commands with SQLExec() all the time, and I never use the semicolon to "chain" the commands.

This is the way I would have done it.
TEXT TO lcSQL TEXTMERGE NOSHOW
update table set x = y where <<condition>>
select @@rowcount as rowcount
ENDTEXT
*&
= sqlexec(liConnection, lcSQL, curResults)
And my question is, are we doing to same thing? Or they're different?

Hope you understand my question.

TIA.
