Integrate connectivity to CSV data with wizards in IntelliJ.
The CData JDBC Driver for CSV enables you to access CSV as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to CSV data in IntelliJ.
Create a JBDC Data Source for CSV
Follow the steps below to add the driver JAR and define connection properties required to connect to CSV data.
- In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.
In the Data Source Properties dialog that appears, the following properties are required:
- JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.csv.jar, located in the installation directory.
- JDBC Driver Class: In this menu, select cdata.jdbc.csv.CSVDriver from the list.
Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:csv: and includes connection properties separated with semicolons.
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.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the CSV JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.csv.jar
Fill in the connection properties and copy the connection string to the clipboard.
A typical JDBC URL is the following:
jdbc:csv:DataSource=MyCSVFilesFolder;
Edit and Save CSV Data
To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor.
