ODBC Driver for Google BigQuery Connection String Parameters - ODBC Driver for Google BigQuery |
|
The following table lists the connection string parameters for BigQuery.
| Parameter | Description |
|---|---|
|
|
The project ID is a unique identifier for a project. |
|
|
The dataset ID is a unique dataset name inside the project namespace. |
|
|
The refresh token that authorizes the driver to access your BigQuery data. |
Proxy Settings |
|
|
|
The proxy hostname or IP address. |
|
|
The proxy port. |
|
|
The proxy username. |
|
|
The proxy password. |
Advanced Settings |
|
|
|
Some parameters don't accept null values when retrieving metadata. If a third-party tool passes a null value to such a parameter, the driver returns an error. By default, these options are enabled for compatibility with such third-party tools. |
|
|
|
|
|
The time (in seconds) to wait for a connection to open before terminating an attempt. The default value is 60. |
ODBC Behavior |
Sets the behavior corresponding to the ODBC specification version expected by a third-party tool. The behavior of the ODBC driver can be changed by calling the SQLSetEnvAttr function to set the SQL_ATTR_ODBC_VERSION environment attribute. Some third-party tools expect the driver to exhibit ODBC 2.x behavior, but forget to call SQLSetEnvAttr with the needed version, or pass an incorrect value. In this case, the behavior can be explicitly set in the connection string.
0
The default value. ODBC behavior is determined by a third-party tool.
2
ODBC 2.x behavior is explicitly set.
3
ODBC 3.x behavior is explicitly set.
|
|
|
Specifies a column or a set of comma-delimited columns that will be returned by the driver as primary keys for BigQuery tables. Google BigQuery has no primary key or unique constraints, which makes it impossible for some third-party tools to work with BigQuery tables correctly. The default column is |
|
|
The time to wait for a query execution result before terminating and generating an error. |
|
|
Enables the use of local regional settings when converting numbers to strings. |
|
|
Enables the use of local regional settings when converting dates and times to strings. |
String Types |
Sets the string value types returned by the driver as Default, ANSI, or Unicode.
Default
The driver defines the string types.
Ansi
All string types are returned as SQL_CHAR, SQL_VARCHAR, and SQL_LONGVARCHAR.
Unicode
All string types are returned as SQL_WCHAR, SQL_WVARCHAR, and SQL_WLONGVARCHAR.
Note: Set the parameter to
Ansi or Unicode if your third-party tool supports only ANSI or Unicode strings.
|
|
|
Specifies whether all the datetime values retrieved from the data source are returned as UTC values or converted to local time and whether the date values specified on the application side (e.g., in SQL statements) are considered UTC or local. The default value is false. |
