| Guys, need your opinion. I need to change the length of a field from char(2) to char(3). The table contains 50 million records. Can i just issue an alter table statement, or is it recommended that i create another table, and copy all the data to the new table...then switch references to the new table..I cannot have more that 1 hour downtime for the system |
