Replicate Multiple SQLite Accounts
Replicate multiple SQLite accounts to one or many databases.
CData Sync for SQLite is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple SQLite connections. In this article we show how to use the CLI to replicate multiple SQLite accounts.
Configure SQLite Connections
You can save connection and email notification settings in an XML configuration file. To replicate multiple SQLite accounts, use multiple configuration files. Below is an example configuration to replicate SQLite to SQLite:
Windows
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
<DatabaseType>SQLite</DatabaseType>
<DatabaseProvider>System.Data.SQLite</DatabaseProvider>
<ConnectionString>Database=\PATH\TO\mysqlite.db</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>Database=\PATH\TO\mysqlite.db</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>
The Database connection property must be set to a valid file path.
Configure Queries for Each SQLite Instance
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 SQLite API. The statement below caches and incrementally updates a table of SQLite data:
REPLICATE MyTable;
You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple SQLite accounts into the same database:
You can use a different table prefix in the REPLICATE SELECT statement:
REPLICATE PROD_MyTable SELECT * FROM MyTable
Alternatively, you can use a different schema:
REPLICATE PROD.MyTable SELECT * FROM MyTable
Run Sync
After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:
Windows
SQLiteSync.exe -g MyProductionSQLiteConfig.xml -f MyProductionSQLiteSync.sql
Java
java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar SQLiteSync.jar -g MyProductionSQLiteConfig.xml -f MyProductionSQLiteSync.sql
