mysql> call sp_demo_in_parameter(@p_in) 略 mysql> select @p_in; 略 以上可以看出,p_in虽然在存储过程中被修改,但并不影响@p_id的值 OUT参数例子 创建: mysql> CREATE PROCEDURE sp_demo_out_parameter(OUT p_out INT) BEGIN SELECT p_out;/*查看输出参数*/ SET p_out=2;/*修改参数值*/ SEL...
DELIMITER 是分隔符的意思,因为MySQL默认是以“;”为分隔符的,如果我们没有声明分隔符的话,那么编译器会把存储过程当成SQL语句进行处理,则存储过程的编译过程就会报错,所以要事先用DELIMITER关键字声明当前段分割符,这样MySQL才会将“;”当做存储过程中的代码,不会执行这些代码,用完之后就把分隔符还原 <7>.存储过程...
The first segments the declarations based on the input parameter and only functionally declares the cursors and fields needed. The second declares all possibly needed fields and cursors, even if it will not use them. DELIMITER $$ /* Declare only what we are using as we need it ...

在sql语句中加入�变量。 declare @local_variable data_type 声明时须要指定变量的类型, 能够使用set和select对变量进行赋值, 在sql语句中就能够使用@local_variable来调用变量 声明中能够提供值,否则声明之后全部变量将初始化为NULL。 比如:declare @id int ...
IF 1=1 BEGIN DECLARE @test VARCHAR SET @test=’1′ PRINT ‘in if:’+@test END GO PRINT ‘out if:’+@test 这下对了,检查语法后SQL报错“必须声明标量变量”@test”” 注:GO就是用于一个sql语句的结束 比如说一个批处理语句是这样的 select *from ,b select *from a 在后一个select后面加上...

This method uses the define() function to define a global variable in PHP. The function takes two parameters. The first parameter is the constant name, and the second is the value of the constant. The constant is case-insensitive by default. We can access the constant from anywhere in the...
