| Index |
The types of indexes and constraints to create for the column, if the table is created. Each index and constraint contains only one column. The valid values for the column type are listed below: PrimaryKey: This type specifies that the column is a primary key for the table. Only one primary key is allowed per table. Unique: This type specifies that the column has a UNIQUE constraint. NotNull: A non-nullable constraint. Null: A nullable constraint. |
