MArk writes "I had a table of 2 columns already filled. I later decided to add a third column which will be my unique key, and auto increments after I have filled it. The table currently has over 300 rows. I want to do a for loop (or alternative) in which I have a variable initialize to 1, and auto increment by 1 and insert into the sid (my unique field) row by row so that it increases as the rows increase. Here is an algorithm for what I am trying to do.
i = 1;
while not end of rows
{
update table
set sid = i for current row
move to next row
i++
}
I would like to know how to do this in SQL, or if possible, I would like the code to do this. I am using MSSQL 7.0. I assume you would need to use transact sql to do this." |
