Below we have listed down some of the differences between stored procedure and function in PL/SQL:Stored ProcedureFunction May or may not returns a value to the calling part of program. Returns a value to the calling part of the program. Uses IN, OUT, IN OUT parameter. Uses only IN ...
procedure:存储过程 eg: create or replace procedure p --这儿是和plsql的区别 is cursor c is select * from emp2 for update; --v_temp c%rowtype; begin for v_temp in c loop if(v_temp.sal< 2000) then update emp2 set sal=sal*2 where current of c ; elsif(v_temp.sal = 5000) the...
1.1.1调用存储过程 在sql工作表中直接调用: exec account_number; 1.1.2存储过程的參数 比如: create or replace procedure proc1 (p_c1 varchar2,p_c2 out varchar2,p_c3 in out varchar2) ls v_c1 varchar(10); begin --p_c1 :=p_c1 || ‘d’; --不能做复制的目标 v_c1:=P_c1; p_c2 ...
SQL> set serverout on; SQL> exec xjyp; test PL/SQL procedure successfully completed ---not in screen SQL> set serverout off; SQL> exec xjyp; PL/SQL procedure successfully completed --- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15...
Let us look at the example that demonstrates how the cursor can be used in PL/ SQL to retrieve the information about a particular entry in the table. Consider that we have a table called customer details which stores the details of the customers. To check the contents of the table, we ...
简介:过程化SQL语言(Procedural Language/SQL)是Oracle数据库对SQL语句的扩展:在普通SQL语句的使用上增加了编程语言的特点,把数据操作和查询语句组织在PL/SQL代码的过程性单元中,通过逻辑判断、循环等操作实现复杂的功能或者计算的程序语言。 引言 过程化SQL语言(Procedural Language/SQL)是Oracle数据库对SQL语句的扩展:...
SQL>BEGIN 2 3 --打印hello world 4 5 DBMS OUTPUT.PUT_LINE( "hello world '); 6 7 END; 8 / PL/SQL过程已执行完成。 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. sqlplus中执行plsql程序,需要在程序最后添加一个 / 标识程序的结束。
package_name:包的名字。 private type and item declarations:声明私有的变量、常量、游标、异常和数据类型。 subprogram bodies :定义公有和私有的PL/SQL子程序。创建包体 CREATE OR REPLACE PACKAGE BODY comm_package ISFUNCTION validate_comm (p_comm IN NUMBER) RETURN BOOLEAN (包中创建函数) IS v_max_comm...
创建PL/SQL Procedure 在Oracle数据库中,可以使用CREATE PROCEDURE语句创建PL/SQL Procedure。下面是一个创建简单PL/SQL Procedure的示例: CREATEORREPLACEPROCEDUREcalculate_salary (emp_idINNUMBER) AS salaryNUMBER; BEGIN -- 根据员工ID查询薪水 SELECTsalaryINTOsalaryFROMemployeesWHEREemployee_id=emp_id; -- 输出...
总库实时库存表; WZGL_JCWZSSKC_CHECK:分库实时库存表; 打开PL Developer 用户登录后,打开“文件-新建->程序窗口->Procedure” 拷贝程序到代码窗口,按F8键执行,如果编译没有通过,修改相应的代码,直至编译通过,。 PLSQL的调试过程简单介绍到这,其它的需要你慢慢去摸索。 发布于 2023-06-12 10:24・ Android...
