ODBC Driver for SAP Sybase Adaptive Server Enterprise

Connection Options

SAP Sybase Adaptive Server Enterprise Connection Options

The following table describes the options that you can include in the connection string for SAP Sybase Adaptive Server Enterprise:
Option Description

Server

Serves to supply the server name for login.

Port

Used to specify the port number for the connection. 5000 by default.

Username

Used to supply a user name for login.

Password

Used to supply a password for login.

Database

Used to set the name of the database

ConnectionTimeout

Used to specify the time in seconds before an attempt to make a connection is considered unsuccessful.

IPVersion

Used to specify the version of the Internet Protocol. IPv4 and IPv6 are available. The IPv4 + IPv6 value allows to check for available protocol versions and use the first available automatically.

Advanced Settings

Option Description

Empty strings as NULL

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.

Allow NULL strings

RegionalNumberSettings

Enables using local regional settings when converting numbers to string.

RegionalDateTimeSettings

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

AllowFixedTypes

Adaptive Server Enterprise cannot distinguish SQL_CHAR from SQL_VARCHAR, SQL_WCHAR from SQL_WVARCHAR, and SQL_BINARY from SQL_VARBINARY on preparing an SQL statement. It can break compatibility with some third-party tools. So the driver always returns SQL_VARCHAR instead of SQL_CHAR, SQL_WVARCHAR instead of SQL_WCHAR, and SQL_VARBINARY instead of SQL_BINARY in metadata. To change this behavior and allow returning fixed types in metadata, this parameter should be set to True.

Example Connection String

User ID=sa;Server=ASEserver;Data Source=master;Port=5000;
