1、定义 所谓存储过程(Stored Procedure),就是一组用于完成特定数据库功能的SQL语句集,该SQL语句集经过编译后存储在数据库系统中。在使用时候,用户通过指定已经定义的存储过程名字并给出相应的存储过程参数来调用并执行它,从而完成一个或一系列的数据库操作。 2、存储过
在Oracle数据库中,存储过程(Stored Procedure)是一种预先编译好的PL/SQL代码块,可以接收参数、执行特定任务并返回结果。要执行Oracle存储过程,您需要遵循以下步骤: 1...
Oracle long objects can be passed to and from stored procedures in pretty much the same way as you would with native SQL.The following example demonstrates a call to the blog.edit_entry procedure using a CLOB. In this example no value is assigned to the id parameter so it will correspond...
To do so, you define a function activity that makes a server-side call to the appropriate WF_DIRECTORY API and include that function activity in your process diagram. See: Standard API for PL/SQL Procedures Called by Function Activities and Workflow Directory Service APIs, Oracle Workflow API ...
To implement a referential integrity check, create a PL/SQL stored procedure which takes the table unique key(s) as its argument(s) and raises an exception if deleting the row would cause a referential integrity error. See: Integrity Checking LONG, LONG RAW and RAW Datatypes Avoid creating ta...
PL/SQL procedure successfully completed. SQL> call dbms_output.put_line('called'); 调用完成。 SQL> select sql_text 2 from v$session 3 join v$mystat 4 using (sid) 5 join v$sql 6 on (v$sql.sql_id = v$session.prev_sql_id)
3.stored procedure can be used many times to reduce database developer work task. 4.high safety,set a user to use specify stored procedure )可设定只有某用户才具有对指定存储过程的使用权。 1.basic syntax create [or replace] procedure pro_name [parameter1[,parameter2]] is|as ...
1.PLS-00306: wrong number or types of arguments in call to ‘QUERYUSER’ ORA-06550: line 1, column 7: PL/SQL: Statement ignored 原因:这个问题是少参数,或者类型不对,我的原因是函数的返回值没有接收,也就是没有设置函数返回值的参数;
