Connection String Parameters - ODBC Driver for SendGrid

API Key

The API key allows authorization of a specific application to access SendGrid data. To save your API key in the DSN settings, select the Save API key checkbox.

Advanced Settings

Allow NULL strings

To retrieve metadata, not all parameters according to MSDN can accept a null value. If NULL, the driver should return an error. But some 3rd-party tools pass NULL to the parameters. These options should be enabled for compatibility with such tools.

Empty strings as NULL

Connection Timeout

The time (in seconds) to wait for a connection to open before terminating an attempt. The default value is 60.

ODBC Behavior

Used to set the behavior corresponding to the ODBC specification version that a third-party tool expects. The behavior of ODBC driver can be changed by setting a value for the SQL_ATTR_ODBC_VERSION attribute by calling the SQLSetEnvAttr function. But some third-party tools expect the driver to exhibit ODBC 2.x behavior, but forget to call SQLSetEnvAttr with the specified version or pass an incorrect value there. In this case, the required behavior can be explicitly specified in the Connection String by setting the ODBC Behavior parameter. The possible values are:

• Default - default ODBC behavior determined by a third-party tool.
• Ver 2.x - ODBC 2.x behavior is explicitly set.
• Ver 3.x - ODBC 3.x behavior is explicitly set.

RegionalNumberSettings

Enables the use of local regional settings when converting numbers to strings.

RegionalDateTimeSettings

Enables the use of local regional settings when converting dates and times to strings.

ReturnForeignKeys

Use the option to specify whether the driver must return foreign keys. Retrieving metadata about foreign key constraints is a time-consuming operation; many third-party tools request foreign key metadata even whey they do not actually need this information. Note that enabling the parameter may degrade performance of data access operations. The default value is False.

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 will be returned as SQL_CHAR, SQL_VARCHAR and SQL_LONGVARCHAR.
• Unicode - all string types will be returned as SQL_WCHAR, SQL_WVARCHAR and SQL_WLONGVARCHAR.

The parameter value should be changed if any third-party tool supports only Ansi string types or Unicode ones.

Custom Fields

Allows accessing custom table fields.

QueryTimeout

The time to wait for a query execution result before terminating and generating an error.

UTC Dates

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.
