From 1a321fea71db878755a4a2c00d45b98e10842a92 Mon Sep 17 00:00:00 2001 From: Michael Meskes Date: Wed, 11 Feb 2015 11:13:11 +0100 Subject: Fixed array handling in ecpg. When ecpg was rewritten to the new protocol version not all variable types were corrected. This patch rewrites the code for these types to fix that. It also fixes the documentation to correctly tell the status of array handling. --- doc/src/sgml/ecpg.sgml | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) (limited to 'doc/src/sgml') diff --git a/doc/src/sgml/ecpg.sgml b/doc/src/sgml/ecpg.sgml index d081ed66625..3ce5f66f4ea 100644 --- a/doc/src/sgml/ecpg.sgml +++ b/doc/src/sgml/ecpg.sgml @@ -1375,10 +1375,13 @@ EXEC SQL END DECLARE SECTION; Arrays - SQL-level arrays are not directly supported in ECPG.
