OUT parameters in PREPARE

    XMLWordPrintable

    Details

      Description

      Current — 10.1.1 — implementation of OUT parameters in PREPARE is as follows:

      PREPARE .... "SELECT ... INTO ?, ?, ...";
      EXECUTE .... USING @var1, @var2, ...

      It is non-standard. And it's not strictly necessary, as there are easy workarounds.

      Standard syntax is

      PREPARE .... "SELECT ... ";
      EXECUTE ... INTO @var1, @var2, ...

      The workaround is:

      PREPARE .... "SELECT ... INTO @var1, @var2, ...";
      EXECUTE ....

      We should consider changing the syntax to be standard or removing this feature completely.
