Xailer & OZ Software

Hello,
I need in code to identify - is TDataField is BlobField (contain a binary
data) or not. How can I do it in Xailer-syntax? Something like:
for x := 1 to oDataSet:FieldCount()
if oDataSet:aFields[x] ...is BlobField //??
........
else
........
endif
next

In my working exampes it seems such code works ok:
for x := 1 to oDataSet:FieldCount()
if oDataSet:aFields[x]:nSQLType = 205
But I am not sure that it's common case. Where is the list of all possible
values for :nSQLType placed?
