Question

JDBC或Hibernate在调用存储过程时显示奇怪的行为。

以下是示例代码：

return session.createSQLQuery("select * from pr_ss_coo_10x('31748','NEWRX',null,'5053')")
    ..
    ....tolist();

投掷错误

但是，当我通过SQL Anywhere客户端触发相同的查询时，它正常工作。 Sybase错误代码文档说

“您没有提供足够数量的主机变量绑定变量，或语句，或SELECT列表项的数量。“

我检查过两次，结果集与Pojo正确映射。 此问题可能的根本原因是什么？

Answer 1

绕过Hibernate事务管理使用PreparedStatement完成了技巧和获取结果集。

Connection con = DriverManager.getConnection(url, user, password); PreparedStatement ps = con.prepareStatement( "select * from pr_ss_coo_10x(@param1=?,@param2=?, @param3=?, @param4=? )"); ResultSet rs = ps.executeQuery();

这不是解决方案，只是一种解决方法。
