The next step is to specify the table columns: column name, column type and size if applicable, then the options specific to a column such as PRIMARY KEY, the AUTOINCREMENT option applies to number type columns, the FOREIGN KEY constraint to reference a column from another table, the constraint NOT NULL, default value, CHECK sets a constraint on the column.Įach row inserted in a SQLite table contains a special column called “rowid”, which specifies a unique id for each row. If it is not specified, then the table will be created in the default scheme. The schema_name option represents the name of the schema in which the table is created. If the table with the given name exists, then it does not create it.
