From 7c4d3fe272f3ab62b36f21e3fa6ae00751f00e31 Mon Sep 17 00:00:00 2001 From: Fujii Masao Date: Tue, 22 Oct 2024 23:56:37 +0900 Subject: [PATCH] ecpg: Refactor ecpg_log() to skip unnecessary calls to ECPGget_sqlca(). Previously, ecpg_log() always called ECPGget_sqlca() to retrieve sqlca, even though it was only needed for debug logging. This commit updates ecpg_log() to call ECPGget_sqlca() only when debug logging is enabled.
