server| Scripts | Data uses SQL Server 2000 's own build SQL Scripts tool to generate SQL scripts to create tables, views, stored procedures, and so on. So can the data in the table also be generated as SQL scripts that automatically import data into SQL Server after executing the scripts in Query Analyzer? The answer is yes. The following stored procedure is written by an expert, and the man's surname is no longer known, but this monumental work is occasionally seen in the SQL Server community. CREATE PROCEDURE dbo. Outputdata
@tablename sysname
As
DECLARE @column varchar (1000)
DECLARE @columndata varchar (1000)
DECLARE @sql varchar (4000)
DECLARE @xtype tinyint
declare @name sysname
DECLARE @objectId int
declare @objectname sysname
DECLARE @ident int

SET NOCOUNT ON
Set @objectId =object_id (@tablename)
If @objectId is null--Determines whether an object exists
Begin
Print @tablename + ' object does not exist '
Return
End Set @objectname =rtrim (object_name (@objectId))
If @objectname is null or CHARINDEX (@objectname, @tablename) =0
Begin
Print @tablename + ' object not in current database '
Return
End If OBJECTPROPERTY (@objectId, ' istable ') < > 1--Determine if the object is a table
Begin
Print @tablename + ' object is not a table '
Return
End Select @ident =status&0x80 from syscolumns where id= @objectid and status&0x80=0x80 If @ident is not null
print ' SET identity_insert ' + @TableName + ' on '--defines a cursor, iterates through the data, and generates an INSERT statement
DECLARE syscolumns_cursor cursor FOR

Set @column = '

FETCH NEXT from Syscolumns_cursor into @name, @xtype
