Bryan Bende commented on NIFI-1841:
-----------------------------------
In JdbcCommon we have this code:
{code}
else if (javaSqlType == BINARY || javaSqlType == VARBINARY || javaSqlType ==
LONGVARBINARY || javaSqlType == ARRAY || javaSqlType == BLOB || javaSqlType ==
CLOB) {
// bytes requires little bit different handling
byte[] bytes = rs.getBytes(i);
ByteBuffer bb = ByteBuffer.wrap(bytes);
rec.put(i - 1, bb);
}
{code}
I think we have to consider breaking out some of these cases, at least blob and
clob, so that they use rs.getBlob() and rs.getClob().
