Can someone explain how DELAYED_OUT_FORMAT works and its purpose in general?
To be precise, here is a piece of call log from my provider:
0037ce20 ODBCAttachment::prepare("select Point_ID, Max_PDOP from
dbase_03", 3, 47)
0037cfb8 ODBCStatement::getOutputMetadata()
Returning metadata 00266e14
0037cfb8 ODBCStatement::getOutputMetadata()
Returning metadata 002670b4
0037cfb8 ODBCStatement::getInputMetadata()
Returning metadata 00267354
0037cfb8 ODBCStatement::openCursor(0)
Input metadata (0 fields)
Use external metadata 00000001
I cannot understand why IStatement::openCursor() got DELAYED_OUT_FORMAT as outMetadata
after it was asked for output metadata twice and returned them.
