MySQL IN condition limit
Hey, I have to use IN condition in my MySQL statement with a large set of ids.
Example
SELECT * FROM users WHERE id IN (1,2,3,4...100000)
Is there a limit if items the IN statement can have?
No there isn't, check the manual about the IN function:
The number of values in the
INlist is only limited by the max_allowed_packet value.
As far as I know in mysql, there is no limit for items in the IN statement.
In oracle altough, there is a limit of 1000 items in the IN statement.
But more the items in IN, your query performance will slow down unless that column is indexed.
