I would like to have access to the Seconds_Behind_Master field, (as returned by SHOW SLAVE STATUS) from inside a stored procedure.
I can’t figure out how to get its value inside a variable. None of the usual SET/SELECT syntax seems to work.
Is there a way to do that?
Just for the record: it has turned out to be possible to open a cursor for SHOW statements. This allows to parse the output and work with it inside a stored procedure.
