Hi @Ajith_143
Use DateTime.ParseExact(“Columnname” ,“mm-dd-yyyy”,System.Globalization.InvariantCulture.CultureInfo)
(or)
CDate(row(“ColumnName”).ToString

Hi @Ajith_143

Use for each row in Dt
Use Assign and pass the query as DateVar=CDate(row(“ColumnName”).ToString

Use for each row in Dt —Okay
Use Assign and pass the query as DateVar=CDate(row(“ColumnName”).ToString
in Assign
LHS has to be a varaible where did i create the variable. You said its a date type , you are saying to put a Type in LHS or create a variable of type date and put it in LHS

Hi @SyedShabaz03

in LHS give it as DateVar and in Variable Panel change the data type as DateTime

Thanks
