Detailed Description
Efficiently pull data directly out of a table.
A TableReader provides efficient read access to a database table. This is not as flexible as a normal query using the Result class however:
- Can only dump tables, not views or arbitrary queries
- Has no knowledge of metadata
- Is unable to reorder, rename, omit or enrich fields
- Does not support filtering of records
On the other hand, it can read rows of data and transform them into any container or container-like object that supports STL back-inserters. Since the TableReader has no knowledge of the types of data expected, it treats all fields as strings.
