i have tried data type unicode string [dt_wstr], string [dt_str], unicode text stream [dt_ntext]. in sql server have changed column data type varchar, char, nvarchar also.

in above sample data, col1, col2 composite key, row 2, row 4, duplicated want records deleted.

kindly me in this.

sam ponna.

 

hi sam,

your error messages state string compose long. maximum length ntext is  (i believe) 230 characters, if combine col1 col2 row 7 exceed value. try [dt_wstr] adequate length have max string length ccombinging col2 , col2..

cees

please remember mark replies answers or @ least vote helpfull if , unmark them if provide no help.
