Sql Hibernate抱怨双单报价

我正在尝试使用Hibernate选择一些数据
查询结果如下所示

"select mystuff from mytable where upper(mystuff)=upper('a''c')"

（a'c来自用户输入，由

StringEscapeUtils.escapeSql（）

）转义

Hibernate给了我一个SQLGrammarException。我把那句话漏掉了吗？

我认为

'

漏掉

'

很好。我想Hibernate+某些RDBMS可能会在转义这些引号时出错。您应该尝试使用

preparedStatement

或

Query

。要使用如下方法向您注入数据：

String selectSQL = "select mystuff from mytable where upper(mystuff)=upper(?)";
PreparedStatement preparedStatement = dbConnection.prepareStatement(selectSQL);
preparedStatement.setString(1, "a'c");
ResultSet rs = preparedStatement.executeQuery(selectSQL);
while (rs.next()) {
    String mystuff = rs.getString("mystuff");
}

Query query = session.createQuery("from mytable where upper(mystuff)=upper(:mystuff)");
query.setString("mystuff", "a'c");
List<?> list = query.list();

或者像这样：

String selectSQL = "select mystuff from mytable where upper(mystuff)=upper(?)";
PreparedStatement preparedStatement = dbConnection.prepareStatement(selectSQL);
preparedStatement.setString(1, "a'c");
ResultSet rs = preparedStatement.executeQuery(selectSQL);
while (rs.next()) {
    String mystuff = rs.getString("mystuff");
}

Query query = session.createQuery("from mytable where upper(mystuff)=upper(:mystuff)");
query.setString("mystuff", "a'c");
List<?> list = query.list();

Query Query=session.createQuery（“来自mytable，其中upper（mystuff）=upper（：mystuff）”；
query.setString（“mystuff”、“a'c”）；
List=query.List（）；

所以hibernate将能够处理它

希望有帮助：）
