Defaults

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The DEFAULT expression on a column definition defines what value the column should contain if it is omitted in an INSERT statement, or if an explicit DEFAULT expression is used in INSERT or UPDATE. By default, this is NULL in most dialects

// Create a new table with a column with a default expression
create.createTable("table")
      .column("column1", INTEGER.default_(1))
      .execute();

To trigger this DEFAULT expression, you can run this, for example:

// Insert a row using the default expression
create.insertInto(table(name("table"))).defaultValues().execute();
