存储过程(Stored Procedure)是在大型数据库系统中,一组为了完成特定功能的SQL 语句集,存储在数据库中,经过第一次编译后再次调用不需要再次编译,用户通过指定存储过程的名字并给出参数(如果该存储过程带有参数)来执行它。存储过程是数据库中的一个重要对象。 语法 create or replace procedure <过程名>[参数名 参数模...
The first stored procedure (SPSingleRefCur) will be executed by using the generic OpenAccessContext.Execute<T> method. Because you are using an Oracle specific type in the stored procedures, you need to pass an OracleParameter to the context. You need to set the OracleDbType property of the...

When you invoke a stored procedure on an Oracle server, the following limitations apply: OUT parameters aren't supported. The return value isn't available because the stored procedure doesn't return any results. The response size limit is 8MB. The request size limit is 2MB. Oracle native quer...

The Oracle JDBC driver supports bind variables of type REFCURSOR. A REFCURSOR is represented by a JDBC ResultSet. Use the getCursor method of the CallableStatement to convert a REFCURSOR value returned by a PL/SQL block into a ResultSet. JDBC lets you call a stored procedure that executes a ...
