Sql decimal to crystal big decimal

[nfesselet]

Here is my go at issue #3.

While testing I also found a bug triggered when reading data after a NULL value.

Nice work 👍 . Handling Nermics is a bit tricky as different vendors and drivers either support or ignore it. SQL Server ignores scale on input params and output columns, Oracle handling of this is totally weired, as it inserts group separators (commas in US, periods in some countries).

Some database vendors supports a money type which also inserts currency symbols. So keeping track of all these different treatments by different vendors is quite difficult and heavy.

I believe BigDecimal is going to blow with these scenarios, best bet would be to manually parse the String and ignore all specials characters, just keep digits, decimal point, negtive signs and then pass it to BigDecimal for conversion.

While testing I also found a bug triggered when reading data after a NULL value.

Can you please be more specific on what error you encountered? and is that re-producible?

Please also run the specs to ensure that code still passing the db api specs.
