Command line utility (Settings->Command line) let you run DDL-like commands with simplified syntax.

Syntax is (use empty line to separate commands):

    COMMAND [Options]
    [Additional options]

Available commands:

1. CREATE TABLE [TableName]
   [FieldName] [FieldType]
2. ALTER TABLE [TableName]
   ADD [FieldName] [FieldType]
   DROP [FieldName]
3. DROP TABLE [TableName]

Example:

    CREATE TABLE MyTable
    MyField1 int
    MyField2 bool

    ALTER TABLE MyTable
    ADD MyField3 int
    DROP MyField1

    DROP TABLE MyTable
