Preparing UPDATE statement in ESQL/C

Hi, all! Is there any way in ESQL/C after $PREPAREing an UPDATE statement like: "update table1 set (field1,...) = (?,...,?) where <condition>" to find out the next info: - how many columns are being updated; - sqlvar entries for each of them; that is fully determined sqlda structure? When preparing INSERT/SELECT statements, sure, I have it, but what can I do with UPDATE? Thanks in advance. Bespaly Alex
