Hello List, I have acquired the task of maintaining and existing application that uses postgresql. I am only lightly versed in sql and have the following problem I need to solve. I have a table in which each row has a column - row_number. The row_numbers need to be sequential. Everything is fine until a row in the middle of the table gets deleted, now I need to renumber the remaining rows so they are sequential again. The table is small, typically less than a 100 rows. Is there a simple way to do this in sql. I know I can dump the table to an external file and then use 'C' or a bash script to fix up the row_numbers and then reload the table - but it seems there is probably a more elegant way to do this in sql. Anyway thanks for any tips. Steve
