Ok, i think i've found my/sqlite problem sqlite_column_decltype and sqlite_column_type are both returning null, so zeos (and presumably sql express) don't know which type to request from http://www.sqlite.org/c3ref/column_decltype.html <http://www.sqlite.org/c3ref/column_decltype.html>"If this statement is a SELECT statement and the Nth column of the returned result set of that SELECT is a table column (not an expression or subquery) then the declared type of the table column is returned. If the Nth column of the result set is an expression or subquery, then a NULL pointer is returned. "
both count(1) and cast(count(1) as integer) return null type using above functions On 6 January 2011 03:43, Richard Hipp <d...@sqlite.org> wrote: > On Wed, Jan 5, 2011 at 10:27 PM, Vannus <van...@gmail.com> wrote: > > > I know sqlite stores data as text, > > > No it doesn't, unless the value really is text. > > > > but why does > > count(1) and cast(count(1) as integer) give a text result? > > > > It will give you the result in any format you ask it to.
