我希望有一种方法可以将存储过程的副本复制到存储过程中,其名称类似于sp_oldprocedureName_yyyymmddhhmiss,编程方式如下:
(以下代码是我的“内涵”代码)
declare @DateExtension char(14)
select @DateExtension = substring(CONVERT(varchar(30), getdate(), 120), 1,4) + substring(CONVERT(varchar(30), getdate(), 120), 6, 2)+ substring(CONVERT(varchar(30), getdate(), 120), 9, 2)+ substring(CONVERT(varchar(30), getdate(), 120), 12, 2)+ substring(CONVERT(varchar(30), getdate(), 120), 15, 2)+ substring(CONVERT(varchar(30), getdate(), 120), 18, 2)
declare @OldName, @NewName varchar(255)
set @OldName = 'sp_OldProcedureName'
set @NewName = @OldName + '_' + @DateExtension
sp_copy(@OldName, @NewName) --This sp_copy does not exist, but I'm looking for an equivalent.
那么,是否有类似上述“sp_copy”的程序?

好的 - 尝试以下方法。该过程应该按照您的指定工作。它将从sql_modules获取procs定义并使用新名称执行它。可能需要进行一些调试。
CREATE PROCEDURE spCopy @OLDNAME NVARCHAR(255), @NEWNAME NVARCHAR(255)
AS
BEGIN
DECLARE @SQL NVARCHAR(MAX)
SELECT @SQL = REPLACE(definition,@OLDNAME,@NEWNAME)
FROM sys.sql_modules
WHERE object_ID(@OLDNAME) = object_id
EXEC @SQL
END

您可以创建以下存储过程:
CREATE PROCEDURE sp_copy
(@OldName VARCHAR(255),
@NewName VARCHAR(255))
AS BEGIN
BEGIN TRY
DECLARE @definition NVARCHAR(MAX), @sql NVARCHAR(MAX);
SELECT @definition = m.definition
FROM sys.procedures p
JOIN sys.sql_modules m ON p.OBJECT_ID = m.OBJECT_ID
WHERE name LIKE @OldName;
IF @definition IS NULL
BEGIN
PRINT 'There is no stored procedure with name: ''' + @OldName + '''';
END;
ELSE
BEGIN
SET @definition = REPLACE(@definition, @OldName,@NewName);
SET @definition = REPLACE(@definition, '''','''''');
SET @sql = 'EXEC(''' + @definition + ''')';
EXEC(@sql);
PRINT 'Stored procedure duplicated successfully.';
END;
END TRY
BEGIN CATCH
PRINT 'There was an issue copying the stored procedure.';
END CATCH;
END;
GO
然后执行如下代码:
DECLARE @OldName VARCHAR(255) , @NewName VARCHAR(255);
DECLARE @DateExtension CHAR(14);
SELECT @DateExtension = SUBSTRING(CONVERT(VARCHAR(30), GETDATE(), 120), 1,4) + SUBSTRING(CONVERT(VARCHAR(30), GETDATE(), 120), 6, 2)+ SUBSTRING(CONVERT(VARCHAR(30), GETDATE(), 120), 9, 2)+ SUBSTRING(CONVERT(VARCHAR(30), GETDATE(), 120), 12, 2)+ SUBSTRING(CONVERT(VARCHAR(30), GETDATE(), 120), 15, 2)+ SUBSTRING(CONVERT(VARCHAR(30), GETDATE(), 120), 18, 2);
SET @OldName = 'sp_OldProcedureName';
SET @NewName = @OldName + '_' + @DateExtension;
EXEC dbo.sp_copy @OldName, @NewName;
