The process D2000 DBManager was tested and should work with these databases:
- Oracle Database (versions 9i, 10g, 11g, 12c, 18c, 19c)
Note: We recommend applying available patches of the Oracle client as well as the Oracle ODBC driver - older versions of the Oracle client/driver suffered from various errors (handle leaks, instability, etc.). - Microsoft SQL Server (versions 2000 - 2005)
Note: in a specific situation, the UPDATE trigger was able to affect the DB(S)_UPDATE action so that it failed because the ODBC function SQLRowCount returned 0 (even though the data was updated). This case can be diagnosed by turning on the debugging category RTM.DBMANAGER.UPDATE.MSSQL.0 (if the category is active, it is ignored that SQLRowCount returns 0 changed rows). - Microsoft Access (versions 2000 - XP)
- PostgreSQL (versions 9.x and above). D2000 Dbmanager supports the /NQ startup parameter to better support PostgreSQL (case sensitivity in table and column names).
Note 1: in the configuration of ODBC drivers for PostgreSQL, we recommend setting the "Level of rollback on errors" parameter to Statement. The Nop setting makes the database connection unusable after any error. The Transaction setting will cause some actions to behave non-standardly (e.g. a DB(S)_INSUPD action inserting several rows will not insert anything if an error occurs while inserting any of the rows).
Note 2: in the ODBC driver configuration for PostgreSQL, we recommend setting the "Max Varchar" parameter to a large enough value (larger than the maximum size of VARCHAR columns), otherwise the data may be truncated during page access. Similarly, we recommend setting the "Max LongVarchar" parameter to a sufficiently large value (larger than the maximum VARCHAR data size used in columns whose size is not explicitly specified).
Note 3: in the configuration of ODBC drivers for PostgreSQL, we recommend leaving the "bytea as LO" parameter checked for correct work with BLOBs (DB_READ_BLOB, DB_UPDATE_BLOB). - Sybase Anywhere (versions 6 - 12)
- Informix (driver version 4.10.00.16554, check a Scrollable Cursors option on the Advanced tab and set Cursor Behavior to value "1 - Preserve" on the Environment tab)
- Firebird (version 2.0.4, native ODBC driver or driver from GM - Software)
Note 1: Native ODBC driver (version 2.0.0.148) doesn't enable editing in paged mode (browser in HI, actions PG*). Seemingly editing works but no data are modified in the database.
Note 2: ODBC driver from GM - Software supports editing and inserting rows in paged mode, but it displays only the first row of the table.

- RTM.DBMANAGER.UPSERT - On the PostgreSQL platform when inserting data with the DB(S)_INSUPD action, UPSERT (INSERT ... ON CONFLICT (...) DO UPDATE ) is used. This syntax is supported by PostgreSQL since version 9.5.
- RTM.DBMANAGER.UPDATE.MSSQL.0 - On the Microsoft SQL Server when updating data with DB(S)_UPDATE, DB(S)_INSUPD actions, an erroneously returned 0 affected rows (as a result of the UPDATE trigger on a table) is ignored.
