Do you want to get the number of rows   SELECT columnName  COUNT    AS row count FROM eventsTable WHERE columnName    Business  GROUP BY columnName

Assuming there is a column named business   SELECT Business  COUNT    FROM eventsTable GROUP BY Business

User · Answer

This is probably the easiest way  not the prettiest though   SELECT         SELECT Count    FROM eventsTable WHERE columnName    Business   as RowCount     FROM eventsTable     WHERE columnName    Business    This will also work without having to use a group by  SELECT    COUNT    OVER    as RowCount     FROM eventsTables     WHERE columnName    Business
