Hi there,
I am fetching raw rows. Most time, it works well, but I have bumped into a
pretty weird behaviour with a derived attribute. The attribute is defined like
this:
===
{
className = NSString;
definition = "CAST(C_AUCTION_SEQ as VARCHAR(18))";
externalType = "CHAR VARYING";
name = ceboisAuctionId;
valueType = S;
width = 256;
}
===
(the actual definition is much more complex, but the one above sports the
problem as well; also, I have tried both with valueType=S as shown above and
without a valueType for String/stream default.)
If I fetch raw rows _directly from the table_ which contains the attribute, it
works perfectly, I get strings for 'ceboisAuctionId' in the dictionaries -- in
my raw row dictionaries there are things like e.g., "ceboisAuctionId:28", all
right.
Nevertheless, if I fetch _another_ table which contains a relationship :1
'auction' into this table, and if I add 'auction.ceboisAuctionId' to
fetchSpec.rawRowKeyPaths, I do get the proper value -- but _encoded in NSData_!
In this case, in my raw row dictionaries there are things like e.g.,
"auction.ceboisAuctionId:<class com.webobjects.foundation.NSData (offset=0,
length=3, data=[50]'2', [56]'8', [0]'')>" :-O
This does not happen with normal (non-derived) columns of the same type: e.g.,
for a column
===
{
allowsNull = Y;
className = NSString;
columnName = "C_TITLE";
externalType = "CHAR VARYING";
name = title;
width = 256;
}
===
those I get proper strings in both cases, i.e., regardless they are fetched
directly from the table, or indirectly through a relationship from another
table, in my raw row dictionaries there are always things like
"title:Something" or "auction.title:Something".
Does it make any sense? Could I fix something in my model to get the values
properly converted even if fetched through a relationship and a derived
attribute?
Thanks and all the best,
OC
