This is a multi-part message in MIME format. --------------200659AFE34083CDE19EE8BF Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Hello, We have a software developed with Oracle Pro*C accessing data via Oracle OCA (Open Client Adapter) and ODBC to access Informix databases. All is fine except when we try to retrieve data form varchar and smallint informix fields. In this situation we get the correct value + garbagge (strange characters). With other data types (i. e. char or integer) is working fine. In addition wen we develope software with dev2k 2.1 accessing informix data via OCA and ODBC we get the correct values in all data type fields. can anyone help us? versions: Pro*C: 2.2.3.0.0 Oracle OCA: 2.0.2.15.0 Informix : 7.23 ODBC: Informix CLI 2.5 32 bits (ivinf709.dll) --------------200659AFE34083CDE19EE8BF Content-Type: text/x-vcard; charset=us-ascii; name="mgarcia.vcf" Content-Transfer-Encoding: 7bit Content-Description: Card for Mario Garc'a Content-Disposition: attachment; filename="mgarcia.vcf" begin:vcard n:Garcia Franco;Mario tel;fax:96 346 32 33 tel;work:96 346 32 50 x-mozilla-html:FALSE url:www.centrisa.es org:Centrisa - Val'ncia adr:;;C/ Ricardo Mic' 5;Val'ncia;;46009; version:2.1 email;internet:mgarcia@vlc.centrisa.es title:Cap de Projecte note:Salutacions x-mozilla-cpt:;15408 fn:Mario Garcia Franco end:vcard --------------200659AFE34083CDE19EE8BF--
