存储过程(Stored Procedure),是一组为了完成特定功能的SQL 语句,类似一门程序设计语言,也包括了数据类型、流程控制、输入和输出和它自己的函数库。存储过程可以说是一个记录集,它是由一些T-SQL语句组成的代码块,这些T-SQL语句代码像一个方法一样实现一些功能(对单表或多表的增删改查),然后再给这个代码块取一个...
A procedure can have a maximum of 2100 parameters; each assigned a name, data type, and direction. Optionally, parameters can be assigned default values.The following section provides information about passing values into parameters and about how each of the parameter attributes is used during a ...

When a parameter of the function has a default value, the keyword DEFAULT must be specified when the function is called to retrieve the default value. This behavior is different from using parameters with default values in stored procedures in which omitting the parameter also implies the default...

If the query is inside a stored procedure, the current values passed to any parameters. RECOMPILE is a useful alternative to creating a stored procedure. RECOMPILE uses the WITH RECOMPILE clause when only a subset of queries inside the stored procedure, instead of the whole stored procedure, ...

default 参数的默认值。 如果为参数定义了默认值,则无需指定此参数的值即可执行过程。 默认值必须是常量或 NULL。 该常量值可以采用通配符的形式,这使其可以在将该参数传递到过程时使用 LIKE 关键字。 只有CLR 过程的默认值记录在 sys.parameters.default 列中。 对于 Transact-SQL 过程参数,该列将为 NULL。 OUT...
