Replicate CSV Data to Multiple Databases

Replicate CSV data to disparate databases with a point-and-click configuration.

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

Configure Replication Destinations

Using CData Sync, you can replicate CSV data to any number of databases, both cloud-based and on-premises. To add a replication destination, navigate to the Connections tab.

For each destination database:

  1. Click Add Connection.
  2. Select a destination. In this article, we use SQLite.
  3. Enter the necessary connection properties. To replicate CSV to a SQLite database, enter a file path in the Data Source box.
  4. Click Test Connection to ensure that the connection is configured properly.
  5. Click Save Changes.

Configure the CSV Connection

You can configure a connection to CSV from the Connections tab. To add a connection to your CSV account, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select a source (CSV).
  3. Configure the connection properties.

    The DataSource property must be set to a valid local folder name.

    Also, specify the IncludeFiles property to work with text files having extensions that differ from .csv, .tab, or .txt. Specify multiple file extensions in a comma-separated list. You can also set Extended Properties compatible with the Microsoft Jet OLE DB 4.0 driver. Alternatively, you can provide the format of text files in a Schema.ini file.

    Set UseRowNumbers to true if you are deleting or updating in CSV. This will create a new column with the name RowNumber which will be used as key for that table.

  4. Click Connect to ensure that the connection is configured properly.
  5. Click Save Changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

Replicate Entire Tables

To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

Customize Your Replication

You can use a SQL query to customize your replication. 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 CSV API. To customize your replication, click Add Custom Query in the Tables section and define the Query Statement.

The statement below caches and incrementally updates a table of CSV data:

REPLICATE Customer;

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 CSV accounts into the same database:

  • Use a different table prefix in the REPLICATE SELECT statement:

    REPLICATE PROD_Customer SELECT * FROM Customer;
  • Alternatively, use a different schema:

    REPLICATE PROD.Customer SELECT * FROM Customer;

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 15 minutes to once every month.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your CSV data to disparate on-premises, cloud-based, and other databases.
