Connecting to SAP ASE (SybaseToSQL)

To migrate SAP Adaptive Server Enterprise (ASE) databases to SQL Server or SQL Azure, you must connect to the Adaptive Server that contains the databases that you want to migrate. When you connect, SSMA obtains metadata about all databases on the Adaptive Server and displays database metadata in the Sybase Metadata Explorer pane. SSMA stores information about the database server, but does not store passwords.

Your connection to ASE stays active until you close the project. When you reopen the project, you must reconnect to ASE if you want an active connection to the server.

Metadata about the Adaptive Server is not automatically updated. Instead, if you want to update the metadata in Sybase Metadata Explorer, you must manually update the metadata, as described in the "Refreshing Sybase ASE Metadata" section later in this topic.

Required ASE Permissions

The account that is used to connect to ASE must have at least public access to the master database and to any source databases to be migrated to SQL Server or SQL Azure. In addition, to select permissions on tables that are being migrated, the user must have SELECT permissions on the following system tables:

  • [source_db].dbo.sysobjects
  • [source_db].dbo.syscolumns
  • [source_db].dbo.sysusers
  • [source_db].dbo.systypes
  • [source_db].dbo.sysconstraints
  • [source_db].dbo.syscomments
  • [source_db].dbo.sysindexes
  • [source_db].dbo.sysreferences
  • master.dbo.sysdatabases

Establishing a Connection to ASE

When you connect to an Adaptive Server, SSMA reads the database metadata on the database server, and then adds this metadata to the project file. This metadata is used by SSMA when it converts the objects to SQL Server or SQL Azure syntax, and when it migrates data to SQL Server or SQL Azure. You can browse this metadata in the Sybase Metadata Explorer pane and review properties of individual database objects.


Before you try to connect to the database server, make sure that the database server is running and can accept connections.

To connect to Sybase ASE

  1. On the File menu, select Connect to Sybase.

    If you previously connected to Sybase, the command name will be Reconnect to Sybase.

  2. In the Provider box, select any of the installed providers on the machine to connect to Sybase server.

  3. In the Mode box, select either Standard mode or Advanced mode.

    Use standard mode to specify the server name, port, user name, and password. Use advanced mode to provide a connection string. This mode is usually only used for troubleshooting or working with technical support.

  4. If you select Standard mode, provide the following values:

    1. In the Server name box, enter or select the name or IP address of the database server.
    2. If the database server is not configured to accept connections on the default port (5000), enter the port number that is used for Sybase connections in the Server port box.
    3. In the User name box, enter a Sybase account that has the necessary permissions.
    4. In the Password box, enter the password for the specified user name.
  5. If you select Advanced mode, provide a connection string in the Connection string box.

    Examples of different connection strings are as follows:

    1. Connection strings for Sybase OLE DB Provider:

      For Sybase ASE OLE DB 12.5, an example connection string is as follows:

      Server Name=sybserver;User ID=MyUserID;Password=MyP@$$word;Provider=Sybase.ASEOLEDBProvider;

      For Sybase ASE OLE DB 15, an example connection string is as follows:

      Server=sybserver;User ID=MyUserID;Password=MyP@$$word;Provider= ASEOLEDB;Port=5000;

    2. Connection string for Sybase ODBC Provider:

      Driver=Adaptive Server Enterprise;Server=sybserver;uid=MyUserID;pwd=MyP@$$word;Port=5000;

    3. Connection string for Sybase ADO.NET Provider:

Reconnecting to Sybase ASE

Your connection to the database server stays active until you close the project. When you reopen the project, you must reconnect if you want an active connection to the Adaptive Server. You can work offline until you want to update metadata, load database objects into SQL Server or SQL Azure, and migrate data.

Refreshing Sybase ASE Metadata

Metadata about the ASE databases is not automatically refreshed. The metadata in Sybase Metadata Explorer is a snapshot of the metadata when you first connected to the Adaptive Server, or the last time that you manually refreshed metadata. You can manually update metadata for a single database, a single database schema, or all databases.

To refresh metadata

  1. Make sure that you are connected to the Adaptive Server.

  2. In Sybase Metadata Explorer, select the check box next to the database or database schema that you want to update.

  3. Right-click Databases or the individual database or database schema, and then select Refresh from Database.

  4. If you are asked to check the current object, click Yes.
