addcond :: (Storable k, Storable v) => TDBQRY -> k -> Condition -> v -> IO ()Source
Add a narrowing condition to a query object.
setlimit :: TDBQRY -> Int -> Int -> IO ()Source
Set the limit number of records of the result of a query object.
search :: (Storable k, Sequence q) => TDBQRY -> IO (q k)Source
Execute the search of a query object. The return value is a list object of the primary keys of the corresponding records.
Arguments
| :: (Storable k, Storable v, Associative m) | |
| => TDBQRY | Query object. |
| -> (v -> m k v -> IO (PostTreatment m k v)) | the iterator function called for each record. |
| -> IO Bool | If successful, the return value is true, else, it is false. |
Process each record corresponding to a query object.
