如何在SQL Server数据库中一次删除所有存储过程？

Question

目前，我们在脚本文件中为每个存储过程使用单独的drop语句：

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[MySP]')   
  AND type in (N'P', N'PC'))  
DROP PROCEDURE [dbo].[MySP] 

有没有办法一次性将它们全部丢弃，或者可能在一个循环中？

Answer 1

我更喜欢这样做：

• 首先通过检查系统目录视图生成要删除的存储过程列表：

   SELECT 'DROP PROCEDURE [' + SCHEMA_NAME(p.schema_id) + '].[' + p.NAME + '];' FROM sys.procedures p 

  这将在SSMS输出窗口中生成DROP PROCEDURE语句列表。

• 将该列表复制到新的查询窗口中，并可能对其进行调整/更改然后执行它

没有杂乱和缓慢的游标，使您能够检查并仔细检查您的实际删除之前要删除的过程列表

Answer 2

类似于（ 使用SQL Server中的存储过程从数据库中删除所有过程 ）。

顺便说一句，这似乎是一件非常危险的事情，只是一个想法......

declare @procName varchar(500)
declare cur cursor 

for select [name] from sys.objects where type = 'p'
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec('drop procedure [' + @procName + ']')
    fetch next from cur into @procName
end
close cur
deallocate cur

Answer 3

1. 单击“存储过程”选项卡
2. 按f7显示所有存储过程
3. 按系统表除 Ctrl + A选择所有过程
4. 按删除按钮，然后单击确定。

您可以以相同的方式删除表格和视图。

Answer 4

在db中创建下面的存储过程（从中你想删除sp的db）

然后右键单击该过程 - 单击执行存储过程..

然后单击确定。

create Procedure [dbo].[DeleteAllProcedures]
As 
declare @schemaName varchar(500)    
declare @procName varchar(500)
declare cur cursor
for select s.Name, p.Name from sys.procedures p
INNER JOIN sys.schemas s ON p.schema_id = s.schema_id
WHERE p.type = 'P' and is_ms_shipped = 0 and p.name not like 'sp[_]%diagram%'
ORDER BY s.Name, p.Name
open cur

fetch next from cur into @schemaName,@procName
while @@fetch_status = 0
begin
if @procName <> 'DeleteAllProcedures'
exec('drop procedure ' + @schemaName + '.' + @procName)
fetch next from cur into @schemaName,@procName
end
close cur
deallocate cur

Answer 5

获取数据库中所有存储过程的drop语句SELECT'DROP PROCEDURE'+''+ F.NAME +';' 来自SYS.objects AS F，其中type ='P'

Answer 6

我认为这是最简单的方法：

DECLARE @sql VARCHAR(MAX)='';

SELECT @sql=@sql+'drop procedure ['+name +'];' FROM sys.objects 
WHERE type = 'p' AND  is_ms_shipped = 0

exec(@sql);

Answer 7

DECLARE @sql VARCHAR(MAX)
SET @sql=''
SELECT @sql=@sql+'drop procedure ['+name +'];' FROM sys.objects
WHERE type = 'p' AND  is_ms_shipped = 0
exec(@sql);

Answer 8

试试这个，它对我有用

DECLARE @spname sysname;
DECLARE SPCursor CURSOR FOR
SELECT SCHEMA_NAME(schema_id) + '.' + name
FROM sys.objects
WHERE type = 'P';
OPEN SPCursor;
FETCH NEXT FROM SPCursor INTO @spname;
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC('DROP PROCEDURE ' + @spname);
FETCH NEXT FROM SPCursor INTO @spname;
END
CLOSE SPCursor;
DEALLOCATE SPCursor;

Answer 9

DECLARE @DeleteProcCommand NVARCHAR(500)

DECLARE Syntax_Cursor CURSOR
FOR
SELECT 'DROP PROCEDURE ' + p.NAME
FROM sys.procedures p

OPEN Syntax_Cursor

FETCH NEXT FROM Syntax_Cursor

INTO @DeleteProcCommand

WHILE (@@FETCH_STATUS = 0)
BEGIN

EXEC (@DeleteProcCommand)

FETCH NEXT FROM Syntax_Cursor
INTO @DeleteProcCommand

END

CLOSE Syntax_Cursor

DEALLOCATE Syntax_Cursor

Answer 10

试试这个：

DECLARE @sql NVARCHAR(MAX) = N'';

SELECT @sql += N'DROP PROCEDURE dbo.'
  + QUOTENAME(name) + ';
' FROM sys.procedures
WHERE name LIKE N'spname%'
AND SCHEMA_NAME(schema_id) = N'dbo';

EXEC sp_executesql @sql;

Answer 11

符合ANSI标准，无光标

DECLARE @SQL national character varying(MAX) 
SET @SQL= ''

SELECT @SQL= @SQL+ N'DROP PROCEDURE "' + REPLACE(SPECIFIC_SCHEMA, N'"', N'""') + N'"."' + REPLACE(SPECIFIC_NAME, N'"', N'""') + N'"; '
FROM INFORMATION_SCHEMA.ROUTINES 

WHERE (1=1) 
AND ROUTINE_TYPE = 'PROCEDURE' 
AND ROUTINE_NAME NOT IN 
(
     'dt_adduserobject'
    ,'dt_droppropertiesbyid'
    ,'dt_dropuserobjectbyid'
    ,'dt_generateansiname'
    ,'dt_getobjwithprop'
    ,'dt_getobjwithprop_u'
    ,'dt_getpropertiesbyid'
    ,'dt_getpropertiesbyid_u'
    ,'dt_setpropertybyid'
    ,'dt_setpropertybyid_u'
    ,'dt_verstamp006'
    ,'dt_verstamp007'

    ,'sp_helpdiagrams'
    ,'sp_creatediagram'
    ,'sp_alterdiagram'
    ,'sp_renamediagram'
    ,'sp_dropdiagram'

    ,'sp_helpdiagramdefinition'
    ,'fn_diagramobjects'
    ,'sp_upgraddiagrams'
) 


ORDER BY SPECIFIC_NAME 


-- PRINT @SQL
EXEC(@SQL) 

没有游标，非ansi兼容：

DECLARE @sql NVARCHAR(MAX) = N''
, @lineFeed NVARCHAR(2) = CHAR(13) + CHAR(10) ;

SELECT @sql = @sql + N'DROP PROCEDURE ' + QUOTENAME(SPECIFIC_SCHEMA) + N'.' + QUOTENAME(SPECIFIC_NAME) + N';' + @lineFeed
FROM INFORMATION_SCHEMA.ROUTINES 
WHERE ROUTINE_TYPE = 'PROCEDURE' 
-- AND SPECIFIC_NAME LIKE 'sp[_]RPT[_]%'


AND ROUTINE_NAME NOT IN 
( 
    SELECT name FROM sys.procedures WHERE is_ms_shipped <> 0 
) 


ORDER BY SPECIFIC_NAME 


-- PRINT @sql 
EXECUTE(@sql)

Answer 12

通过混合游标和系统过程，我们将有一个优化的解决方案，如下所示：

DECLARE DelAllProcedures CURSOR
FOR
    SELECT name AS procedure_name 
    FROM sys.procedures;
OPEN DelAllProcedures
DECLARE @ProcName VARCHAR(100)
FETCH NEXT 
FROM DelAllProcedures
INTO @ProcName
WHILE @@FETCH_STATUS!=-1
BEGIN 
    DECLARE @command VARCHAR(100)
    SET @command=''
    SET @command=@command+'DROP PROCEDURE '+@ProcName
    --DROP PROCEDURE  @ProcName
    EXECUTE (@command)
    FETCH NEXT 
    FROM DelAllProcedures
    INTO @ProcName
END
CLOSE DelAllProcedures
DEALLOCATE DelAllProcedures

Answer 13

符合ANSI标准，无光标

PRINT ('1.a. Delete stored procedures ' + CONVERT( VARCHAR(19), GETDATE(), 121));
GO
DECLARE @procedure NVARCHAR(max)
DECLARE @n CHAR(1)
SET @n = CHAR(10)
SELECT @procedure = isnull( @procedure + @n, '' ) +
'DROP PROCEDURE [' + schema_name(schema_id) + '].[' + name + ']'
FROM sys.procedures

EXEC sp_executesql @procedure
PRINT ('1.b. Stored procedures deleted ' + CONVERT( VARCHAR(19), GETDATE(), 121));
GO

Answer 14

试试这个：

declare @procName varchar(500)
declare cur cursor 

for SELECT 'DROP PROCEDURE [' + SCHEMA_NAME(p.schema_id) + '].[' + p.NAME + ']'
FROM sys.procedures p 
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec( @procName )
    fetch next from cur into @procName
end
close cur
deallocate cur
