Attribute Conformance

The following table indicates the conformance level of each ODBC environment attribute, where this is well-defined.

Function

Conformance level

SQL_ATTR_CONNECTION_ POOLING	- [1]
SQL_ATTR_CP_MATCH	- [1]
SQL_ATTR_ODBC_VER	Core
SQL_ATTR_OUTPUT_NTS	- [1]

[1] This is an optional feature and as such is not part of the conformance levels.

The following table indicates the conformance level of each ODBC connection attribute, where this is well-defined.

Function

Conformance level

SQL_ATTR_ACCESS_MODE	Core
SQL_ATTR_ASYNC_ENABLE	Level 1/Level 2 [1]
SQL_ATTR_AUTO_IPD	Level 2
SQL_ATTR_AUTOCOMMIT	Level 1
SQL_ATTR_CONNECTION_TIMEOUT	Level 2
SQL_ATTR_CURRENT_CATALOG	Level 2
SQL_ATTR_LOGIN_TIMEOUT	Level 2
SQL_ATTR_ODBC_CURSORS	Core
SQL_ATTR_PACKET_SIZE	Level 2
SQL_ATTR_QUIET_MODE	Core
SQL_ATTR_TRACE	Core
SQL_ATTR_TRACEFILE	Core
SQL_ATTR_TRANSLATE_LIB	Core
SQL_ATTR_TRANSLATE_OPTION	Core
SQL_ATTR_TXN_ISOLATION	Level 1/Level 2 [2]

[1] Applications that support connection-level asynchrony (required for Level 1) must support setting this attribute to SQL_TRUE by calling SQLSetConnectAttr; the attribute need not be settable to a value other than its default value through SQLSetStmtAttr. Applications that support statement-level asynchrony (required for Level 2) must support setting this attribute to SQL_TRUE using either function. [2] For Level 1 interface conformance, the driver must support one value in addition to the driver-defined default value (available by calling SQLGetInfo with the SQL_DEFAULT_TXN_ISOLATION option). For Level 2 interface conformance, the driver must also support SQL_TXN_SERIALIZABLE.

The following table indicates the conformance level of each ODBC statement attribute, where this is well-defined.

[1] Applications that support connection-level asynchrony (required for Level 1) must support setting this attribute to SQL_TRUE by calling SQLSetConnectAttr; the attribute need not be settable to a value other than its default value through SQLSetStmtAttr. Applications that support statement-level asynchrony (required for Level 2) must support setting this attribute to SQL_TRUE using either function. [2] For Level 2 interface conformance, the driver must support SQL_CONCUR_READ_ONLY and at least one other value. [3] For Level 1 interface conformance, the driver must support SQL_CURSOR_FORWARD_ONLY and at least one other value. For Level 2 interface conformance, the driver must support all values defined in this document.
