How to write my own sdbc driver
Pre implementation steps
- search all occurances of skeleton and replace them to a name which you prefer
1. Implement a class called driver or modify the existing skeleton -> have a look at SDriver.?xx
2. Implement a class called connection -> have a look at SConnection.?xx
3. Have a look at the DatabaseMetaData -> see SDatabaseMetaData.cxx
The methods which should be implemented at least are
- getTableTypes
- getTables
- getTypeInfo
- getColumns
4. You need a statement to show/access some data -> have a look at SStatement.cxx
-> especially executeQuery()
5. The ResultSet: without you see nothing -> look at SResultSet.cxx
6. The ResultSetMetaData needed to get some information about what are waiting for us
-> look at SResultSetMetaData.cxx
7. The prepared statement is the last class we have to implement now
-> you have to allow statements like "SELECT * FROM table WHERE id = ?"
8. congratulations you have now implement your own driver :-)
