Delete many rows from a table using id in Mysql

if you need to keep only a few rows, consider

DELETE FROM tablename WHERE id NOT IN (5,124,221);

This will keep only some records and discard others.

how about using IN

DELETE FROM tableName
WHERE ID IN (1,2) -- add as many ID as you want.

The best way is to use IN statement :

DELETE from tablename WHERE id IN (1,2,3,...,254);

You can also use BETWEEN if you have consecutive IDs :

DELETE from tablename WHERE id BETWEEN 1 AND 254;

You can of course limit for some IDs using other WHERE clause :

DELETE from tablename WHERE id BETWEEN 1 AND 254 AND id<>10;
