The cap_capability column in the iidbcapabilities catalog contains one or more of the following values:
Capability
Value
OPEN/SQL_LEVEL
Version of OpenSQL supported by the DBMS. Use this name in preference to the older COMMON/SQL_LEVEL. Default setting is 00605.
COMMON/SQL_LEVEL
Version of OPEN/SQL support provided by the DBMS. Maintained for backward compatibility. (Use OPEN/SQL_LEVEL instead.) Examples:
00600 Version 6.0
00601 Version 6.1
00602 Version 6.2
Default is 00600.
DB_NAME_CASE
Case mapping semantics of the database with respect to regular identifiers for database objects:
LOWER for lowercase is the Ingres setting.
UPPER for uppercase is set for an ISO Entry SQL92 compliant installation.
DB_DELIMITED_CASE
Case mapping semantics of the database with respect to delimited identifiers for database objects:
LOWER for lowercase is the Ingres setting. MIXED for mixed case is set for an ISO Entry SQL92 compliant installation.
If the value is MIXED, an identifier must be enclosed in double quotes to maintain case as originally defined. Otherwise it is treated as a regular identifier (converted to uppercase).
DB_REAL_USER_CASE
Case mapping of user names as retrieved by the operating system:
LOWER for lowercase is the Ingres setting. MIXED for mixed case or UPPER for uppercase is set as specified during installation.

The type of DBMS the application is communicating with. For a Star Server, the value is always STAR.
DISTRIBUTED
