Boolean in databases

Question

Can ayone tell me what's the easiest way to store 'boolean' values into a
database?
Most of the database types described in the data conversion tables of
chapter 4 of "Accessing Databases" can only be selected into or inserted
from a boolean value, but not both!
TIA.

Answer 1

Can ayone tell me what's the easiest way to store 'boolean' values into a
database?convert the boolean value to an integer value an write it as
a smallint (e.g.
for ODBC) into the database.
smallint is only 16 bit but you don't get a problem with the
integerdata type
because it's range is between 0 and 1
e.g.
convertBooleanToInteger(BooleanValue:boolean) : integer
If BooleanValue then
return(1);
else
return(0);
end if;
and
convertIntegerToBoolean(IntegerValue:integer) : boolean
If IntegerValue = 1 then
return(TRUE);
else
return(FALSE);
end if;There should be no need to convert it between an integer and a boolean.
We read/write the boolean directly from/to the database. The database
side is SMALLINT DEFAULT 0 NOT NULL and the forte attribute is boolean.
Forte handles the conversion.
