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_DEAD | 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.

[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.
