26 // pointer would normally be used for doing things as database lookups
27 // for user login names and passwords, getting workstation settings, etc.
28 // ---> IMPORTANT <---
29 //
30 // For each database object created which uses this wxDb pointer
31 // connection to the database, when a CommitTrans() or RollBackTrans()
32 // will commit or rollback EVERY object which uses this wxDb pointer.
33 //
34 // To allow each table object (those derived from wxDbTable) to be
35 // individually committed or rolled back, you MUST use a different
36 // instance of wxDb in the constructor of the table. Doing so creates
37 // more overhead, and will use more database connections (some DBs have
38 // connection limits...), so use connections sparringly.
39 //
40 // It is recommended that one "main" database connection be created for
41 // the entire program to use for READ-ONLY database accesses, but for each
42 // table object which will do a CommitTrans() or RollbackTrans() that a
43 // new wxDb object be created and used for it.
