Exporting Boolean Data to Databases

Logical data is exported from the MATLAB workspace to a database as type BOOLEAN.

This example adds two rows of data to the Invoice table in the dbtoolboxdemo

database.

In the MATLAB workspace, create I, the structure you want to export.

I.InvoiceNumber{1,1}=456789;

I.Paid{1,1}=logical(0);

I.InvoiceNumber{2,1}=987654;

I.Paid{2,1}=logical(1);

For Data operation, choose Insert.

In Data source, select dbtoolboxdemo.

In Tables, select Invoice.

In Fields, select Paid and InvoiceNumber.

Assign results to the MATLAB workspace variable I.

Click Execute to run the query.

VQB inserts two new rows into the Invoice table.

View the table in Microsoft Access to verify that the data was correctly inserted.
