Hi Igor, thank you very much.
i follow the documents for sqlite function and change the sql to: ----------- SELECT t.variable, t.value, ifnull(d.value, group_concat(substr(t.value,1,0),'off')) state FROM globals t LEFT JOIN globals d ON (substr(t.variable,5) = substr( d.variable,12) and t.variable LIKE 'OUT\_%' ESCAPE '\' and d.variable LIKE 'OUTDISABLE\_%' ESCAPE '\') ORDER BY t.variable; --------- always get SQL error: no such function: group_concat, but the sqlite documents have this function! thanks 2008/2/12, Igor Tandetnik <[EMAIL PROTECTED]>: > > "li yuqian" <[EMAIL PROTECTED]> wrote in > message > news:[EMAIL PROTECTED] > > > > i tried your sql, but get a error: > > --------- > > SQL error: no such function: substring > > -------- > > In SQLite, it's named substr.
