Metadata (Numeric precision)

Hi,
for small numeric columns, the ResultSetMetaData-Class seems to return wrong information for getPrecision and getColumnDisplaySize:
real precision getprecision getColumnDisplaySize
1 1 3
2 1 3
3 1 3
4 2 4
5 3 5
So the values for NUMERIC(1) and NUMERIC(2) seems to be wrong (we use the getColumnDisplaySize to get the precision for numeric and char columns).
Any ideas?
Thanks.

Sorry for missing that thread.

It's a special process. Because DBF's NUMERIC(1) and NUMERIC(2) can be used to stor e decimal point and sign, so that their precision limited to 1.

... OK, so it is programatically not possible to get the precision
with which the column was created? Or is there another API or function?
Thanks in advance.

Yeah. It's a confusion for us too, because DBF numeric format won't consider store space for the decimal point and sign, so that it will result issue when convert to other database format.
