Example of adding a data stored procedure after SQL clears table data _mssql

Copy Code code as follows:

ALTER PROCEDURE [dbo]. [Sp_add_jurisdiction]
@CTableName varchar (20),--current table to be deleted, new
@filedkeyValue varchar (20),--value of the field to be deleted
@filedName varchar (20),--Name of the field to be deleted
@filedNameAdd1 varchar (20),--New field name 1
@filedNameAdd2 varchar (20),--New field name 2
@sql varchar (6000)--new value-added strings, such as: 25,30;25,31

Begin
DECLARE @strSQL_1 varchar (6000)--delete
