new ADO functions

Postby lucasdebeltran » Thu Jul 18, 2013 8:41 am

Hello,

Continuing with great and very usefull ADO functions created by Mr. Nages, it would be very interesting to have also the following:

- Optimice table.
- Backup table.


Thank you very much.
Muchas gracias. Many thanks.

Un saludo, Best regards,

Harbour 3.2.0dev, Borland C++ 5.82 y FWH 13.06 [producción]

Implementando MSVC 2010, FWH64 y ADO.

Abandonando uso xHarbour y SQLRDD.

- Optimice table.
- Backup table.


Both of your requests are have different answers depending on your Database. With MS Access you can 'compact and repair' as well as just copying the .mdb or .accDb using code .. however, Sql Server and Oracle are not that simple and require a Data Base Administrator to perform those tasks.

From my notes I recall the parameters defined as ??

Code: Select all  Expand view

cConnectionString1 := "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=MyDatabase.mdb"
cConnectionString2 := "Provider=Microsoft.Jet.OLEDB.4.0;ataSource=MyCompactedDatabase.mdb"
 



Thanks

cConnectionString1 is the ConnectionString of the current .mdb
cConnectionString2 is the ConnectionString of the new ( repaired ) .mdb

Very exciting funcions.

MySQL has the command OPTIMIZE TABLE.
