Hi There,

I have a field in my database that contain comma seperated values these values are numbers, and I am trying to do a search and count the number of times that a number appears in that column throughout the column,

$sql = "SELECT sector_id_csv, COUNT(sector_id_csv) as count FROM cv WHERE sector_id_csv LIKE '$sectorId'";

This seems slow and does not return any results, and I know the sector_id it is search exsists in the table.
