        <preConditions onFail="MARK_RAN">
            <not>

            </not>
        </preConditions>
        <createTable tableName="FSM">
            <column autoIncrement="true" name="ID" type="BIGINT">
                <constraints primaryKey="true"/>
            </column>
            <column name="FT_EXP" type="VARCHAR(100)"/>
