I’ve got a table in MySQL that has a Primary Key Column.
ID | Value 1 | One 2 | Two 6 | Three 8 | Four 9 | Five
How do I get it to be:
ID | Value 1 | One 2 | Two 3 | Three 4 | Four 5 | Five
There are no other tables. Just the one.
I just want the ID to be in a proper series.
A Query perhaps.. 🙂

There is even a simple way to accomplish the result by writing this query
SET @newid=0; UPDATE tablename SET primary_key_id=(@newid:<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6d502d03081a0409">[email protected]</a>+1) ORDER BY primary_key_id;
This query will reindex the primary key starts from
Seems to me you have two options.
1) create a new table and copy the existing data over.
2) add another autoincrement field to the existing table, then delete the original column.
ALTER TABLE tableName ADD NewIdn INT NOT NULL AUTO_INCREMENT KEY
I did this in phpmyadmin by unchecking the A_I box (Auto Increment setting), clicking save, and then checking it again, and clicking save again.
