Attribute Conformance of ODBC Supported APIs in Snappy Driver

ODBC Environment Attribute

Attributes	Conformance Level	Supported in Snappy Driver	Exceptions
SQL_ATTR_CONNECTION_POOLING	[1]	Yes	This is an optional feature and as such is not part of the conformance levels.
SQL_ATTR_CP_MATCH	[1]	Yes
SQL_ATTR_ODBC_VER	Core	Yes
SQL_ATTR_OUTPUT_NTS	[1]	Yes

ODBC Connection Attribute

Attributes	Conformance Level	Supported in Snappy Driver	Exceptions
SQL_ATTR_ACCESS_MODE	Core	Yes
SQL_ATTR_ASYNC_ENABLE	Level 1/Level 2[1]	Yes	Applications that support connection-level asynchronously (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 asynchronously (required for Level 2) must support setting this attribute to SQL_TRUE using either function.
SQL_ATTR_AUTO_IPD	Level 2	No
SQL_ATTR_AUTOCOMMIT	Level 1	Yes	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.
