SQL server use in pdd working kaisay karay ga

[@monday6740]

1:30 DELETE causes redo, TRUNCATE does not, if I am correct (on Oracle at least), because DELETE is part of INSERT/UPDATE/DELETE set, and TRUNCATE is not

[@rahulkherde]

Correct.. delete do a log entry..

[@ak6877]

Those are DML including SELECT

[@athiraprabhakaran7281]

Truncate is a DDL command and all DDLs are auto commit.. where as Delete is a DML command.. so u can roll back after performing delete .

[@mohammedmujtabaahmed8337]
