Question

I’ve been trying to do the same thing as in How can I tell when a MySQL table was last updated? but for multiple table names. I can’t seem to get it right. I want to retrieve the update_time for five tables and I assumed I had to do something like

WHERE TABLE_NAME = 'Table1' AND TABLE_NAME = 'Table2' AND TABLE_NAME = 'Table3'

but this doesn’t seem to work as it just picks up one name all the time. I’d appreciate any advice you can give me.

Notice the difference between the AND and OR logical operators:

WHERE TABLE_NAME = 'Table1' OR TABLE_NAME = 'Table2' OR TABLE_NAME = 'Table3'
