How SQL Server accesses the tables of the Sybase database

　　One install Sybase client

Version: Sybase Client 11.9.2 for NT

1 after the installation completes, the operation starts-> program->sybase->dsedit

2 Select Menu ' Server Object ',-> ' Add ' to enter service name like 1.70

3 then select ' 1.70 ' in the server list, double-click the dialog box on the right, and select Add in the Network Address dialog box, for example 132.228.1.70,4300,ok OK

4 Select the Ping Server button on the toolbar to test whether the server can be connected (red lightning-like button)

　　Second, create DSN in ODBC

Administrative Tools-> Data source ODBC

Create a new System DSN with the name set to 1.70

In the Create New Data Source dialog box, select the ' Sybase System11 ' data source driver,

DSN Datasouce name for the General property: fill in 1.70,

Database: Fill in Sybase database name

OK save

　　third, establish a linked server

Enterprise Manager-> Security-> build linked server-> new linked server

1) in the regular label column

Name Sybase,

Server type Choose a different data source, select Microsoft OLE DB Provider for ODBC in the name of the provider,

Data source: Fill in the DSN name 1.70

2) Security column

Local Login Fill SA

Remote users and remote passwords fill in Sybase username and password

3 Use this security context to establish a connection

Remote Login Enter Sybase username and password

Enter a password with a password

OK save

　　four use SA identity Login Query Analyzer

You can detect Sybase data by executing the following SQL statement

SELECT * from Linked server name (this example is Sybase). Sybase's database name. dbo.sybase's Table name

Note: If you find this problem when you execute a query: the OLE DB provider "MSDASQL" of the linked server "Sybase" provides inconsistent metadata for the column.

Solution:: Do not directly with the SELECT * from Sybase.dbname.dbo.tablename this statement, change the statement, you can solve the problem. The statements are as follows: SELECT * FROM OPENQUERY (Sybase, ' select * from Dbname.dbo.tablename ')
