Insert Rows Generator

This stored proc is used to generate INSERT STATEMENTS for inserting rows into a Table:

CREATE PROC sp_InsertGenerator

DECLARE @dataType nvarchar(1000) --data types returned for respective columns
SET @string='INSERT '+@tableName+'('
SET @stringData=''
DECLARE @colName nvarchar(50)
FETCH NEXT FROM cursCol INTO @colName,@dataType
