Interact with Data in SQLite Database Using MATLAB Interface to SQLite

To analyze your data using SQL in MATLAB® without access to any database or driver, use the MATLAB interface to SQLite. After installing Database Toolbox™, you can use the MATLAB interface to SQLite to move data between MATLAB and an SQLite database file. For details, see MATLAB Interface to SQLite. The SQLite connection is different from a database connection created using a JDBC driver. For background information about SQLite databases, see the SQLite Home Page.

MATLAB Interface to SQLite Advantages

With the MATLAB interface to SQLite, you can start working with data immediately after installing the Database Toolbox by creating an SQLite database file. No installation or administration of software or drivers required. You can share data using SQLite database files. Also, you can deploy a standalone database application without additional installation or configuration on target machines. The MATLAB interface to SQLite supports Windows®, Linux®, and Mac.

MATLAB Interface to SQLite Workflow

To connect to a database quickly and import data, use the MATLAB interface to SQLite. These steps provide a high-level workflow for using the MATLAB interface to SQLite.

  1. Create an SQLite database file by using sqlite. The SQLite database file has a .db extension. The sqlite object signifies an SQLite database connection.

  2. Create tables in the SQLite database file by using execute.

  3. Export your data into the SQLite database file by using sqlwrite.

  4. Import data into MATLAB by using sqlread or fetch.

  5. Perform data analysis in MATLAB.

  6. Export results into the SQLite database file by using sqlwrite.

  7. Close the SQLite connection by using close.

  8. Share the SQLite database file with others.

  9. Create a standalone SQLite database application and deploy it.

MATLAB Interface to SQLite Limitations

The limitations of using the MATLAB interface to SQLite are:

  • NULL values are not supported as the first value in any column.

  • Database import options are not supported.

  • Database Explorer is not supported. Use the command line.
