If v.3.23+, it's a one-step, along the lines of:
ALTER TABLE tablename ADD columnname INT UNSIGNED NOT
NULL PRIMARY KEY AUTO_INCREMENT = 1000
Prior to 3.23, it's a three-step:
1st, alter the table to include the key:
ALTER TABLE tablename ADD columnname INT UNSIGNED NOT
NULL PRIMARY KEY AUTO_INCREMENT
Then, 'trick' the column by--
INSERT INTO tablename (col1, col2, [etc.] columnname)
VALUE ('value1','value2','999')
Then, after inserting your first true record,
DELETE FROM tablename WHERE columnname = '999'
And you're good to go...
