| Method | Returns | Purpose |
|---|---|---|
SQL | TStrings | Writable SQL text (DAO writes before Open/ExecSQL) |
Params | TParams | Query parameters (DAO writes before Open/ExecSQL) |
ExecSQL | Self | Executes INSERT/UPDATE/DELETE |
DataSet | TDataSet | Query result after Open |
Open(aSQL) | Self | Sets SQL and opens in one call |
Open | Self | Opens with SQL already set |
StartTransaction | Self | Begins transaction (check InTransaction first) |
Commit | Self | Commits active transaction |
Rollback | Self | Rolls back active transaction |
&EndTransaction | Self | Delegates to Commit |
InTransaction | Boolean | True if transaction is active |
SQLType | TSQLType | Database type (Firebird, MySQL, SQLite, Oracle) |
