If you reset it in the config window, the query result will take effect in all the opened windows right now. However, If you reset the separator between SQL, it will take effect in the new opened SQL edit window.

       The default Char Fields Seperator is none which means nary a character will be added to the char fields.

 

 

 

5    How to generate the SQL statement to fetch certain record

       How to fetch records that listno are these bellow ?

ListNo
