OP replaced original content and title ca 20100302.
So the replies make sense, here's the original (2009) content (with markup added):
I have connected to SQL DB and i want to execute two queried at a time. For single query i execute it works fine but when i execute another query it gives error
"DBD::ODBC::st execute failed: [Microsoft][ODBC SQL Server Driver]Conn
+ection is busy with result
Use of uninitialized value in concatenation (.) or string at Y:\read_m
+dt.pl line 26, <> line 1."
Please let me know if i am doing something wrong.
