pg_exec dbHandle queryString
Specifies a valid database handle.
Specifies a valid SQL query.
A Tcl error will be returned if Pgtcl was unable to obtain a backend response. Otherwise, a query result object is created and a handle for it is returned. This handle can be passed to pg_result to obtain the results of the query.
pg_exec submits a query to the Postgres backend and returns a result. Query result handles start with the connection handle and add a period and a result number.
Note that lack of a Tcl error is not proof that the query succeeded! An error message returned by the backend will be processed as a query result with failure status, not by generating a Tcl error in pg_exec.
