I tried to use your solution but while creating sp for inserting rows, I ran into a problem, My table has more columns so when I say
"Insert into table1 (col1,col2,col3) values (@Nextstr)"
the sp compiler gives me error that column list has more items than value list. So just to trick that I created a columnstr and passed @Columnstr into Insert statement so now it looks like
"Insert into table1 (@Columnstr) values (@Nextstr)"
now it compiles ok, but runtime it gives error 'table1 object not found'

any idea ? any help is deeply appreciated.

thanks in advance.
