BOOLEAN data type

Informix®

Informix supports the BOOLEAN data type, which can store 't' or 'f' values.

Genero BDL implements the BOOLEAN data type in a different way: A BOOLEAN variable stores integer values 1 or 0 (for TRUE or FALSE). This type is designed to hold the result of a boolean expression.

SAP HANA®

SAP HANA provides a BOOLEAN SQL type, similar to the Genero BDL BOOLEAN type, which is able to store TRUE/FALSE values.

Solution

The SAP HANA database interface supports the BOOLEAN SQL type.

The BOOLEAN type translation can be controlled with the following FGLPROFILE entry:
dbi.database.dsname.ifxemul.datatype.boolean = { true | false }
For more details see IBM Informix emulation parameters in FGLPROFILE.
