pg_exec
Name
pg_exec -- send a command string to the server
Synopsis
pg_exec dbHandle queryString
Inputs
- dbHandle
- Specifies a valid database handle. 
- queryString
- Specifies a valid SQL query. 
Outputs
- resultHandle
- 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_resultto obtain the results of the query.
 
Description
pg_exec submits a query to the PostgreSQL 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.
