pg_send_query Sends asynchronous query &reftitle.description; intboolpg_send_query PgSql\Connectionconnection stringquery pg_send_query sends a query or queries asynchronously to the connection. Unlike pg_query, it can send multiple queries at once to PostgreSQL and get the results one by one using pg_get_result. Script execution is not blocked while the queries are executing. Use pg_connection_busy to check if the connection is busy (i.e. the query is executing). Queries may be cancelled using pg_cancel_query. Although the user can send multiple queries at once, multiple queries cannot be sent over a busy connection. If a query is sent while the connection is busy, it waits until the last query is finished and discards all its results. &reftitle.parameters; connection &pgsql.parameter.connection; query The SQL statement or statements to be executed. Data inside the query should be properly escaped. &reftitle.returnvalues; Returns &true; on success, &false; or 0 on failure. Use pg_get_result to determine the query result. &reftitle.changelog; &Version; &Description; &pgsql.changelog.connection-object; &reftitle.examples; ]]> &example.outputs; &reftitle.seealso; pg_query pg_cancel_query pg_get_result pg_connection_busy
