Question

assume we have to collect data from 2 rows of a table

for example :

select * from table where userid=24

and it returns for example 3 rows of data with different id of row ( auto increment ) , 3 ,35 ,68

I want to know what’s the id of the row before the row with id 35 ( which is 3 ) of about 68 it is 35.

how can I find it by mysql queries?

thank you

Using mysql_insert_id()
Here is a reference to what you need

EDITED

Perhaps you would like to use a query like this

SELECT * FROM table WHERE rowID < (SELECT rowId FROM table WHERE userid=24)
ORDER BY rowId DESC
LIMIT 1
