Lesson 3: Creating a table in your MobiLink consolidated database

This lesson assumes you have completed all preceding lessons. See Lesson 1: Setting up a text file data source.

In this lesson, you create the RemoteOrders table in the MobiLink consolidated database. The table contains the following columns:

Column	Description
order_id	A unique identifier for orders.
product_id	A unique identifier for products.
quantity	The number of items sold.
order_status	The order status.
last_modified	The last modification date of a row. You use this column for timestamp-based downloads, a common technique used to filter rows for efficient synchronization.

Create the RemoteOrders table

Connect to your database from Interactive SQL.

You can start Interactive SQL from Sybase Central or at 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=mldirect_db"

Execute the following SQL statement in Interactive SQL to create the RemoteOrders table.

CREATE TABLE RemoteOrders (
    order_id           INTEGER NOT NULL,
    product_id         INTEGER NOT NULL,
    quantity           INTEGER,
    order_status       VARCHAR(10) DEFAULT 'new',
    last_modified      TIMESTAMP DEFAULT CURRENT TIMESTAMP,
    PRIMARY KEY(order_id)
);

Interactive SQL creates the RemoteOrders table in your consolidated database.

Execute the following statement in Interactive SQL to create 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";
Interactive SQL applies syncsa.sql to your consolidated database. Running syncsa.sql creates a series of system tables and stored procedures prefaced with ml_. The MobiLink server works with these tables and stored procedures in the synchronization process.
Proceed to Lesson 4: Adding synchronization scripts.
