You should probably turn this into a UNION and put an index on each column: SELECT f_tag_ch_y_bottom AS ftag FROM data_cst WHERE f_tag_ch_y_bottom = 'E-CD7' UNION ALL SELECT f_tag_ch_x_bottom AS ftag FROM data_cst WHERE f_tag_ch_x_bottom = 'E-CD7' UNION ALL SELECT f_tag_bottom_minor_axis AS ftag F

I know I cannot use an alias in a where clause, but I am trying to figure out how to achieve what I need. If I could have an alias in a where clause my sql would look like this: SELECT IFNULL(f_tag_bottom, IFNULL(f_tag_bottom_major_axis, IFNULL(f_tag_bottom_minor_
