dblink_exec

DBLINK_EXEC(3)						  PostgreSQL 9.2.7 Documentation					    DBLINK_EXEC(3)

NAME

       dblink_exec - executes a command in a remote database

SYNOPSIS

       dblink_exec(text connname, text sql [, bool fail_on_error]) returns text
       dblink_exec(text connstr, text sql [, bool fail_on_error]) returns text
       dblink_exec(text sql [, bool fail_on_error]) returns text

DESCRIPTION

       dblink_exec executes a command (that is, any SQL statement that doesn't return rows) in a remote database.

       When two text arguments are given, the first one is first looked up as a persistent connection's name; if found, the command is executed on
       that connection. If not found, the first argument is treated as a connection info string as for dblink_connect, and the indicated
       connection is made just for the duration of this command.

ARGUMENTS

       conname
	   Name of the connection to use; omit this parameter to use the unnamed connection.

       connstr
	   A connection info string, as previously described for dblink_connect.

       sql
	   The SQL command that you wish to execute in the remote database, for example insert into foo values(0,'a','{"a0","b0","c0"}').

       fail_on_error
	   If true (the default when omitted) then an error thrown on the remote side of the connection causes an error to also be thrown locally.
	   If false, the remote error is locally reported as a NOTICE, and the function's return value is set to ERROR.

RETURN VALUE

       Returns status, either the command's status string or ERROR.

EXAMPLES

	   SELECT dblink_connect('dbname=dblink_test_standby');
	    dblink_connect
	   ----------------
	    OK
	   (1 row)

	   SELECT dblink_exec('insert into foo values(21,''z'',''{"a0","b0","c0"}'');');
	      dblink_exec
	   -----------------
	    INSERT 943366 1
	   (1 row)

	   SELECT dblink_connect('myconn', 'dbname=regression');
	    dblink_connect
	   ----------------
	    OK
	   (1 row)

	   SELECT dblink_exec('myconn', 'insert into foo values(21,''z'',''{"a0","b0","c0"}'');');
	      dblink_exec
	   ------------------
	    INSERT 6432584 1
	   (1 row)

	   SELECT dblink_exec('myconn', 'insert into pg_class values (''foo'')',false);
	   NOTICE:  sql error
	   DETAIL:  ERROR:  null value in column "relnamespace" violates not-null constraint

	    dblink_exec
	   -------------
	    ERROR
	   (1 row)
