Hi guys, In version 8.2 of the ECPG documentation, section "31.6.3. Different types of host variables" has been added and includesthe following (new) note: 'Note that you have to take care of the length for yourself. If you use this host variable as the target variable of a querywhich returns a string with more than 49 characters, a buffer overflow occurs.' This raises a big question about how to handle fields of type 'text' !? I am pretty sure that in pre-8.0 versions of PostgreSQL ECPG, the arrays were handled in a way that made sure not towrite more than the space allowed (why else have the array size and type size included as parameters in the ECPG generatedoutput call to ECPGdo(...) ?). Is this a new "feature" ? With that note in mind, how do I select from a table field of type 'text' ? Leif
