存储过程

sp_msforeachtable: Runs a command with '?' replaced with each table name (v6.5 and up) sp_msforeachdb: Runs a command with '?' replaced with each database name (v7 and up) sp_who2: just like sp_who, but with a lot more info for troubleshooting blocks (v7 and up) sp_helptext: If you want the code of a stored procedure, view & UDF sp_tables: return a list of all tables and views of database in scope. sp_stored_procedures: return a list of all stored procedures xp_sscanf: Reads data from the string into the argument locations specified by each format argument. xp_fixeddrives:: Find the fixed drive with largest free space sp_help: If you want to know the table structure, indexes and constraints of a table.

我发现这个小脚本非常方便地查看已经部署到服务器上的过程的文本:

DECLARE @procedureName NVARCHAR( MAX ), @procedureText NVARCHAR( MAX )

SET @procedureName = 'myproc_Proc1'

SET @procedureText =    (
                            SELECT  OBJECT_DEFINITION( object_id )
                            FROM    sys.procedures 
                            WHERE   Name = @procedureName
                        )

PRINT @procedureText

在恢复数据库用于测试或其他用途时非常有用。正确地重新映射登录ID:

EXEC sp_change_users_login 'Auto_Fix', 'Mary', NULL, 'B3r12-36'

存储过程的一个技巧是可以从INSERT语句调用它们。当我在SQL Server数据库上工作时，我发现这非常有用。

CREATE TABLE #toto (v1 int, v2 int, v3 char(4), status char(6))
INSERT #toto (v1, v2, v3, status) EXEC dbo.sp_fulubulu(sp_param1)
SELECT * FROM #toto
DROP TABLE #toto
