Driver now honors output format for individual timestamp type. Also returns the value length after conversion.

ODBC Driver 2.13.16

SNOW-36102

Added a parameter to allow the driver to treat big numbers (i.e. precision over 19) as a string.

SNOW-37994

Fixed issue caused by wrong column byte size for VARCHAR type in result set metadata.

ODBC Driver 2.13.15

SNOW-23881

Added support for custom timestamp formatter (pending feature; not currently enabled).

ODBC Driver 2.13.14

SNOW-34096

Added support for custom SQL data types (pending feature; not enabled by default) in result set metadata.

ODBC Driver 2.13.13

SNOW-32391

Fixed an issue that caused large inserts to overflow rowCount.

ODBC Driver 2.13.12

SNOW-31347

Fixed an issue where SQLDescribeCol always returned 6 decimal digits (i.e. microseconds) as the precision for TIME and TIMESTAMP data types, regardless of whether the precision was set to a different value. Now, the driver returns the precision, from 0 (seconds) to 9 (nanoseconds), defined for the data type.

ODBC Driver 2.13.11

SNOW-31998

Added support for SAML 2.0-compliant services/applications for federated authentication by adding the externalbrowser option to the authenticator connection parameter.

ODBC Driver 2.13.10

SNOW-29705

Fixed issue where ODBC sessions were not closing properly; now the driver tries to close sessions in the destructor for the ODBC Connection object.

SNOW-33074

Added support for timezone as a session parameter that can be set in odbc.ini for connecting to Snowflake.

ODBC Driver 2.13.9

SNOW-25562

If metadata_request_use_connection_ctx is set to true, the driver now applies the database name to the ODBC API call if the schema name is not null.

SNOW-31998

Added support for federated authentication/SSO/ADFS.

ODBC Driver 2.13.8

SNOW-31847

For Windows, fixed an issue with a curl failed initialization error.

ODBC Driver 2.13.7

SNOW-30968

Added an ODBC driver property to support noproxy.

ODBC Driver 2.13.6

SNOW-31211

For Windows, applied fix for timestamps older than 1970 to dates.

ODBC Driver 2.13.5

SNOW-31211

For Windows, added internal flag that enables an exception when TIMESTAMP_LTZ is out of range. By default, 1970-01-01 is quietly used in the event of an error. Previously, 1969-12-31 was returned.

ODBC Driver 2.13.4

SNOW-31211

For Windows, fixed issue with timestamps older than 1970 not being supported.

ODBC Driver 2.13.3

SNOW-26793

Added the version number to ODBC packages.

SNOW-28379

For Mac OS, changed the namespace used to identify the installation package for the operating system from com.snowflake.odbc to net.snowflake.odbc.

SNOW-29592

For Linux, changed the underlying SSL library from NSS to OpenSSL. No change to ODBC for Mac OS and Windows.

ODBC Driver 2.12.99

SNOW-22240

Fixed an issue with merge count not adding up.

SNOW-30586

Fixed an issue with number conversion in the driver.

ODBC Driver 2.12.98

SNOW-25562

Added CLIENT_METADATA_REQUEST_USE_CONNECTION_CTX session parameter (to filter object names by the current database and schema if not specified).

ODBC Driver 2.12.97

SNOW-28617

Client package signed with new GPG key (and secret).

ODBC Driver 2.12.96

SNOW-24601

Implemented security patch for federated authentication.

ODBC Driver 2.12.95

SNOW-28234

Added CLIENT_TIMESTAMP_TYPE_MAPPING to the list of parameters that can be set in connection properties.

ODBC Driver 2.12.94

SNOW-25540

Added support for binding timestamp variables as timestamp_ntz for applications that use the bind API to load data into datetime columns (which are equivalent to the timestamp_ntz data type).

SNOW-26451

Implemented CLIENT_SESSION_KEEP_ALIVE session parameter as a supported connection option.

ODBC Driver 2.12.93

SNOW-26953

Fixed an issue which caused network disruptions to return an exception. Now, disruptions return a user error instead of an exception.

ODBC Driver 2.12.92

SNOW-26215, . SNOW-26227

If the client tries to send a delete request to the server for a session that has already expired, the request is ignored.

ODBC Driver 2.12.91

SNOW-25999

Driver processes SQL_DECIMAL as SQL_BIGINT if the scale is set to 0.

ODBC Driver 2.12.90

SNOW-11970

Improved the resiliency for intermittent network errors when receiving query results.

ODBC Driver 2.12.89

SNOW-22102

Fixed a potential deadlock when the main application thread waiting for a result chunk, being downloaded by an asynchronous thread, times out.

SNOW-22351

Improved memory management for downloading large result sets.

SNOW-21795, . SNOW-24366, . SNOW-24519, . SNOW-24589

Improved handling of connection failures and re-establishing a connection.

SNOW-18996

Added support for BINARY data type.

SNOW-22697

Improved performance when fetching large result sets.
