Question

Is it possible to use SUM(FIND_IN_SET("f",ftype)).

Note: type is a varchar type in MYSQL table column.And the possible value are ‘f’, ‘v’, ‘g’.

I want to count the total value of f in a column.

Answer 1

For MySQL:

select sum(FIND_IN_SET('f',ftype) > 0) as total
from your_table

For MSSQL:

select SUM(
           case when CHARINDEX('f', ftype) > 0 
                then 1 
                else 0 
           end
           ) 
       AS total
from your_table
