Data records with empty LVARCHAR fields are not returned(Correcti

Hallo, I have a problem with Informix ODBC driver 3.3 and Micrososft ADO 2.1 and VB6 Data records with empty LVARCHAR fields are not returned. System configuration: Winnt 4.0 Server SP4 Informix ODBC Driver 3.3.0.0000 2.30.TC1 Version 3.30.00.10139 Microsoft VisualBasic 6.0 with Ado 2.1 The error can be reproduced as follows: Create a table: create table AdoTest(f1 varchar, f2 lvarchar)One column of the table is of the data type LVARCHAR. Add data records to the table: insert into AdoTest(f1,f2)Values('a','aaa') insert into AdoTest(f1,f2)Values('b','bbb') insert into AdoTest(f1,f2)Values('c','ccc') Read all records: select * from AdoTest Result is ok. f1 f2 --------- a aaa b bbb c ccc Insert a null string in the field LVACHAR f2. update AdoTest Set f2='' where f1='b' Read all records: select * from AdoTest Result is wrong. f1 f2 -------- a aaa The records from the 2nd record on are missing. select * from AdoTest where f1='b' returns an error message. (No current record available.) If a character is inserted in the field f2, all records are readable again. update AdoTest Set f2='bbb' where f1='b'. This problem does not occur with the driver Informix ODBC 2.80.0007. This one has other problems. Do you have a solution? Regards Nicolas
