Description:
Good afternoon

I would like "SQL_CALC_FOUND_ROWS" to return ZERO if the select query returns a NULL

select SQL_CALC_FOUND_ROWS *
from tABLE X
where ID = 1

If FOUND_ROWS() >1 then

ELSE

END IF;

At the moment it SEEMS that when "FOUND_ROWS()" is performed on a NULL it errors and thus my "ELSE" statement does NOT get called.

I would prefer "FOUND_ROWS()" to return ZERO.

Just like it would have if I had used the "Count()" function.

Peter

How to repeat:
Perform FOUND_ROWS()  on a row where the records returned is NULL

Nothing is returned
