Hi, I'm a novel developer of MySql and now I am trying to create a mysql query to detect
I query a database table every X seconds, and i want to get only the different rows in
the table. The result that I want to have is simply
TABLE (t = now) - TABLE (t = X second ago)
Every time that i query the database I store the table situation in another table, called
TABLE_TEMP, so the operation of difference detection is
TABLE_DIFERENCE = TABLE - TABLE_TEMP.
How can I do this query? The problem that I have is that I don't know the structure of
the table and I want to create a program with can be used for all types of data and
Please help me.
