BOOLEAN data type
Informix®
Informix supports the BOOLEAN
data type, which can store 't' or 'f'
values.
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.PostgreSQL
PostgreSQL supports the BOOLEAN
data type and stores 't'
or
'f'
values for TRUE
and FALSE
representation.
Note: It is not possible to insert the integer values
1
or 0
into
PostgreSQL BOOLEAN
columns: Values must be true
,
false
, 't'
, 'f'
, '1'
or
'0'
.Solution
The PostgreSQL database interface converts the BOOLEAN
integer values to a
CHAR(1)
values '1'
or '0'
.
The
BOOLEAN
type translation can be controlled with the
following FGLPROFILE
entry:dbi.database.dsname.ifxemul.datatype.boolean = { true | false }

more details see IBM Informix emulation parameters in FGLPROFILE.
