issue with twidememo param

Post by robertoicardi » Wed 25 Jan 2012 16:17

dear sirs,

here's what I've found:


postgresql 9.1; database UTF-8
D2006 w all patches; last release of dbexpress driver used

Issue found:

updating a table using parametrized query if there’s a text field to update all goes well if the parameter is set to null or some non-empty string;
if the parameter is set to empty string we receive error ‘insufficient data left in message’in case of unicode on in connection; access violation if unicode is off (but probably because of twidememo datatype in param, didn’t check with ftmemo simple)

In case you need more details pls ask me

to speed up things I've already sent test case zipped file to alexp..

best regards
Roberto Icardi
