ODBC Driver for MailChimp

Connection String Options - ODBC Driver for MailChimp



The following table describes the options that you can include in the connection string for MailChimp:

Option Description

API Key

Your MailChimp API Key (token). See the Obtaining API Key section.

If you want to save the API Key in DSN Settings, select the Save API Key checkbox

API Version

Used to specify the MailChimp API version. The choice of the API version will impact the scope of MailChimp objects and fields available to you. Supported values:

  • Ver 2.0 - MailChimp API 2.0. will be used.
  • Ver 3.0 (default) - MailChimp API 3.0. will be used.

Proxy connection options

Option Description

Proxy Host

If you are using Proxy for connection to your network, specify the Proxy server address in this option. To learn your Proxy server address, open Control Panel->Internet Options->Connections->LAN settings.

Proxy Port

Specify the Proxy port here. You can learn Proxy Port in the same way as described above for the host.

Proxy User

If Proxy User authorization is used, specify Proxy user name (ID) in this option.

Proxy Password

If Proxy User authorization is used, specify Proxy user password in this option.

Advanced Settings

Option Description

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

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.

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 SLQ_LONGVARCHAR.
  • Unicode - all string types will be returned as SQL_WCHAR, SQL_WVARCHAR and SLQ_WLONGVARCHAR.

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

MergeCustomFields

Allows adding custom fields (merge tags). The option can have the following values:

  • None - merge tags are not read from MailChimp.
  • JoinCommon - (default value) merge tags are read from MailChimp, but only the tags that are defined for all the Lists are joined to other ListMembers table columns. Other tags are ignored.
  • JoinAll - all the merge tags are joined to other ListMembers table columns. If a merge tag is not defined for the list, a list member belongs to, NULL value is returned for the corresponding column of this list member.

RegionalNumberSettings

Enables using local regional settings when converting numbers to string.

RegionalDateTimeSettings

Enables using local regional settings when converting dates and times to string.

ConnectionTimeout

The time to wait while trying to establish a connection before terminating the attempt and generating an error.

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.
