Re: Bad data in JDBC ResultSet

Keith_McCully@wunderman.co.uk schrieb:

I've tried :

BigDecimal  bd = rs.getBigDecimal(j) //- rs is ResultSet and j column index.

followed by catch SQLException.

Case 1. DECIMAL length 4 scale 2.
File Data = Hex D5E8D5 (YNY)
Is caught by above and handled OK by setting to zero.

Case 2. DECIMAL length 8 scale 2.
File Data = Hex 4040404040 (Blank)
No exception thrown.

I am looking for a test for case 2 that can identify blank so I can set the
result  to zero.

Any suggestions much appreciated.

Use s = rs.getString(j) and test it for blank and then
bd = new BigDecimal(s) and check for a NumberFormatException
