| | 28 | // |
| | 29 | // For each database object created which uses this wxDb pointer |
| | 30 | // connection to the database, when a CommitTrans() or RollBackTrans() |
| | 31 | // will commit or rollback EVERY object which uses this wxDb pointer. |
| | 32 | // |
| | 33 | // To allow each table object (those derived from wxDbTable) to be |
| | 34 | // individually committed or rolled back, you MUST use a different |
| | 35 | // instance of wxDb in the constructor of the table. Doing so creates |
| | 36 | // more overhead, and will use more database connections (some DBs have |
| | 37 | // connection limits...), so use connections sparringly. |

| | 40 | // the entire program to use for READ-ONLY database accesses, but for each |
| | 41 | // table object which will do a CommitTrans() or RollbackTrans() that a |
| | 42 | // new wxDb object be created and used for it. |
