iphone - Get total number of filled row in table in SQLite -
my question similar mysql, count number of "filled" fields in table
but can not got proper solution. how possible in sqlite?
i know using loop. want query.
please me on issue.
thanks in advance.
a query work:
select count(*) raw rawdata <> '' , rawdata not null
this assumes there table called "raw" , column you're checking against "rawdata"
