odbc driver doesn't support SQL_DECIMAL
Hi, when using the odbc driver with an Oracle database my program crashed with an exception ("Type 3 not supported"). I could fix this by adding a case to the switch statement in line: 922 of file drivers/odbcddbc.d:
case SQL_DECIMAL: return readValue!(char[]);
I'm not experienced with SQL (i want to use ddbc for a sql course at my university) so maybe i miss some subtle issue with this. It also works to convert it to double like this,
case SQL_DECIMAL: return readValue!double;
but in my case the decimal type is used to store user IDs and converting to a floating point type would make no sense...
DECIMAL can be various types depending on the precision that was used:
| Precision | Storage bytes |
|---|---|
| 1 – 9 | 5 |
| 10-19 | 9 |
| 20-28 | 13 |
| 29-38 | 17 |
So it should probably attempt to convert to whichever number type the user is using and error if the data cannot convert correctly.
