From 330864fcda68a90995194576d4ad1ebec1b955e1 Mon Sep 17 00:00:00 2001 From: Staale Smedseng Date: Wed, 12 May 2010 13:19:12 +0200 Subject: Bug #49756 Rows_examined is always 0 in the slow query log for update statements Only SELECT statements report any examined rows in the slow log. Slow UPDATE, DELETE and INSERT statements report 0 rows examined, unless the statement has a condition including a SELECT substatement. This patch adds counting of examined rows for the UPDATE and DELETE statements. An INSERT ... VALUES statement will still not report any rows as examined. sql/sql_class.h: Added more docs for THD::examined_row_count. sql/sql_delete.cc: Add incrementing thd->examined_row_count. sql/sql_update.cc: Add incrementing thd->examined_row_count. --- sql/sql_delete.cc | 2 ++ 1 file changed, 2 insertions(+) (limited to 'sql/sql_delete.cc') diff --git a/sql/sql_delete.cc b/sql/sql_delete.cc index 7e91a37257b..cc29b6f1b6b 100644 --- a/sql/sql_delete.cc +++ b/sql/sql_delete.cc @@ -248,6 +248,7 @@ bool mysql_delete(THD *thd, TABLE_LIST *table_list, COND *conds, free_underlaid_joins(thd, &thd->lex->select_lex); DBUG_RETURN(TRUE); } + thd->examined_row_count+= examined_rows; /* Filesort has already found and selected the rows we want to delete, so we don't need the where clause @@ -304,6 +305,7 @@ bool mysql_delete(THD *thd, TABLE_LIST *table_list, COND *conds, while (!(error=info.read_record(&info)) && !thd->killed && ! thd->is_error()) { + thd->examined_row_count++; // thd->is_error() is tested to disallow delete row on error if (!(select && select->skip_record())&& ! thd->is_error() ) { -- cgit v1.2.1
