pg_getresult

Name

pg_getresult -- Wait for and return result from asynchronous query

Synopsis

pg_getresult conn

Description

pg_getresult waits for the database server to complete a pending asynchronous query, and returns a result handle for the query.

Arguments

conn

The handle of the connection to get a result from.

Return Value

A result handle from the execution of pg_sendquery.

There are no error conditions. This command will block until a result is available. If no asynchronous query is pending, it returns an empty string.

Notes

Caution

This command is part of a new Tcl interface to asynchronous query processing capabilities, and should be considered experimental. The command may change and backwards compatibility is not assured.
