Lesson 2: Generate database schema

In this lesson, you generate the database schema, which includes a Dealer table and a download_cursor synchronization script. A table and stored procedure is used to generate server-initiated synchronization push requests.

 To set up the database schema
  1. Choose Start » Programs » SQL Anywhere 12 » Administration Tools » Sybase Central.

  2. Perform the following tasks to connect to the consolidated database:

    1. From the Connections menu, choose Connect with SQL Anywhere 12.

    2. From the Action dropdown list, choose Connect with an ODBC Data Source.

    3. Click ODBC Data Source Name, and click Browse.

    4. Select sis_cons and then click OK.

    5. Click Connect.

  3. Connect to your database using Interactive SQL.

    You can start Interactive SQL from Sybase Central or from a command prompt.

    • To start Interactive SQL from Sybase Central, right-click the MLconsolidated - DBA database and click Open Interactive SQL.

    • To start Interactive SQL at a command prompt, run the following command:

      dbisql -c "dsn=sis_cons"
  4. Run the following SQL script to create and set up the Dealer table:

    CREATE TABLE Dealer (
        name VARCHAR(10) NOT NULL PRIMARY KEY,
        rating VARCHAR(5),
        last_modified TIMESTAMP DEFAULT TIMESTAMP
    )
  5. Insert data into the Dealer table using the following statements:



    INSERT INTO Dealer(name, rating) VALUES ('Audi', 'a');
    INSERT INTO Dealer(name, rating) VALUES ('Buick', 'b');
    INSERT INTO Dealer(name, rating) VALUES ('Chrysler', 'c');
    INSERT INTO Dealer(name, rating) VALUES ('Dodge', 'd');
    INSERT INTO Dealer(name, rating) VALUES ('Eagle', 'e');
    INSERT INTO Dealer(name, rating) VALUES ('Ford', 'f');
    INSERT INTO Dealer(name, rating) VALUES ('Geo', 'g');
    INSERT INTO Dealer(name, rating) VALUES ('Honda', 'h');
    INSERT INTO Dealer(name, rating) VALUES ('Isuzu', 'I');
    COMMIT;
  6. Run the following SQL script to create the MobiLink system tables and stored procedures. Replace C:\Program Files\SQL Anywhere 12\ with the location of your SQL Anywhere 12 installation.

    READ "C:\Program Files\SQL Anywhere 12\MobiLink\setup\syncsa.sql"
  7. Run the following SQL script to specify a download_cursor synchronization script and record the synchronization:



    CALL ml_add_table_script(
        'sis_ver1',
        'Dealer',
        'download_cursor',
        'SELECT * FROM Dealer WHERE last_modified >= ?'
    );
    
    CALL ml_add_table_script(
        'sis_ver1', 'Dealer', 'download_delete_cursor', '--{ml_ignore}'
    );
    
    COMMIT
