From 5231c26a82a7056f98d99643850754d4e1ebe417 Mon Sep 17 00:00:00 2001 From: Christian Ehrlicher Date: Sat, 7 Dec 2019 20:39:12 +0100 Subject: tst_QSqlQuery: fix some tests Fix some tests in tst_QSqlQuery: - make sure to use QSql::HighPrecision in tst_QSqlQuery::precision() (needed for psql) - remove outdated stuff for mysql 3.x - psql_bindWithDoubleColonCastOperator: the placeholder are stored as named placeholders in psql - avoid some useless old-style casts Change-Id: I54d29a7e24f17d853cce6baa09a67d9278098810 Reviewed-by: Robert Szefner Reviewed-by: Andy Shaw --- tests/auto/sql/kernel/qsqlquery/tst_qsqlquery.cpp | 75 +++++++++++------------ 1 file changed, 36 insertions(+), 39 deletions(-) (limited to 'tests/auto') diff --git a/tests/auto/sql/kernel/qsqlquery/tst_qsqlquery.cpp b/tests/auto/sql/kernel/qsqlquery/tst_qsqlquery.cpp index c75767a513..3b127b7e74 100644 --- a/tests/auto/sql/kernel/qsqlquery/tst_qsqlquery.cpp +++ b/tests/auto/sql/kernel/qsqlquery/tst_qsqlquery.cpp @@ -972,9 +972,7 @@ void tst_QSqlQuery::blob() //don' make it too big otherwise sybase and mysql will complain QByteArray ba( BLOBSIZE, 0 );
