Boolean type in Teradata

Teradata does not natively support a Boolean type. You can use BYTEINT/INT to achieve your purpose.
However,SSDL must be manually modified to enable Teradata ByteInt to Boolean Type mapping. Precision Facet must be set 1 as shown below:
<EntityType Name="BooleanDataType">
     <Key>
          <PropertyRef Name="C01_INTEGER" />
     </Key>
     <Property Name="C2_BOOLEAN" Type="byteint" Precision="1"/>
</EntityType>
