Replicate SQL Server Data to Multiple Databases


Replicate SQL Server data to disparate databases with a single configuration.

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync for SQL Server integrates live SQL Server data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote SQL Server data from Windows or any machine running Java.

You can use Sync's command-line interface (CLI) to easily control almost all aspects of the replication. You can use the CLI to replicate SQL Server data to one or many databases without any need to change your configuration.

Connect to SQL Server Data

You can save connection strings and other settings like email notifications in XML configuration files.

The following example shows how to replicate to SQLite.

Windows

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync><DatabaseType>SQLite</DatabaseType> <DatabaseProvider>System.Data.SQLite</DatabaseProvider> <ConnectionString>User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=1433;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> <TaskSchedulerStartTime>09:51</TaskSchedulerStartTime> <TaskSchedulerInterval>Never</TaskSchedulerInterval> </CDataSync>

Java

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync><DatabaseType>SQLite</DatabaseType><DatabaseProvider>org.sqlite.JDBC</DatabaseProvider> <ConnectionString>User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=1433;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

Connecting to Microsoft SQL Server

Connect to Microsoft SQL Server using the following properties:

  • Server: The name of the server running SQL Server.
  • User: The username provided for authentication with SQL Server.
  • Password: The password associated with the authenticating user.
  • Database: The name of the SQL Server database.

Connecting to Azure SQL Server and Azure Data Warehouse

You can authenticate to Azure SQL Server or Azure Data Warehouse by setting the following connection properties:

  • Server: The server running Azure. You can find this by logging into the Azure portal and navigating to "SQL databases" (or "SQL data warehouses") -> "Select your database" -> "Overview" -> "Server name."
  • User: The name of the user authenticating to Azure.
  • Password: The password associated with the authenticating user.
  • Database: The name of the database, as seen in the Azure portal on the SQL databases (or SQL warehouses) page.

Configure Replication Queries

Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the SQL Server API. The statement below caches and incrementally updates a table of SQL Server data:

REPLICATE Orders;

You can specify a file containing the replication queries. This enables you to use the same replication queries to replicate to several databases.

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

SQLSync.exe -g MySQLiteConfig.xml -f SQLSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar SQLSync.jar -g MySQLiteConfig.xml -f SQLSync.sql
