Replicate Multiple Simplesat Accounts via the CData Sync CLI

CData Sync for Simplesat 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 Simplesat connections. In this article we show how to use the CLI to replicate multiple Simplesat accounts.

Configure Simplesat Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple Simplesat accounts, use multiple configuration files. Below is an example configuration to replicate Simplesat to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
  <DatabaseType>SQLite</DatabaseType>
  <DatabaseProvider>System.Data.SQLite</DatabaseProvider>
  <ConnectionString>Profile=C:\profiles\Simplesat.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';</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>Profile=C:\profiles\Simplesat.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';</ConnectionString>
  <ReplicateAll>False</ReplicateAll>
  <NotificationUserName></NotificationUserName>
  <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

Using API Key Authentication

Simplesat uses API Key authentication. To obtain your API key, log in to your Simplesat account and navigate to Workspace Settings > API. Copy the API key value for use in the connection string.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Simplesat API key obtained from workspace settings.

Configure Queries for Each Simplesat 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 Simplesat API. The statement below caches and incrementally updates a table of Simplesat data:

REPLICATE Surveys;

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 Simplesat accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Surveys SELECT * FROM Surveys 

Alternatively, you can use a different schema:

REPLICATE PROD.Surveys SELECT * FROM Surveys

Run Sync

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

Windows

APISync.exe -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar APISync.jar -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql
