$version = get_info(18); # SQL_DBMS_VER But note that the result needs to be formatted in a particular way: e.g. 06.50.0201 Google found http://www.4d.com/ACIDOC/CMU/CMU11922.HTM saying: SQL_DBMS_VER (ODBC 1.0) A character string indicating the version of the DBMS product accessed by the driver. The version is of the form ##.##.####, where the first two digits are the major version, the next two digits are the minor version, and the last four digits are the release version. The driver must render the DBMS product version in this form, but can also append the DBMS product-specific version as well. For example, "04.01.0000 Rdb 4.1". You might find this interesting: http://www.geocrawler.com/archives/3/105/2001/1/0/5030630/ Driver authors are reminded that the DBI docs say: Because some DBI methods make use of get_info(), drivers are strongly encouraged to support I<at least> the following very minimal set of information types to ensure the DBI itself works properly: Type Name Example A Example B ---- -------------------------- ------------ ------------ 17 SQL_DBMS_NAME 'ACCESS' 'Oracle' 18 SQL_DBMS_VER '03.50.0000' '08.01.0721' 29 SQL_IDENTIFIER_QUOTE_CHAR '`' '"' 41 SQL_CATALOG_NAME_SEPARATOR '.' '@' 114 SQL_CATALOG_LOCATION 1 2 Tim.
