TEXT and BYTE (LOB) types
Informix®
Informix provides the TEXT
,
BYTE
, CLOB
and BLOB
data types to store very
large texts or binary data.
Legacy Informix 4GL applications typically use the
TEXT
and BYTE
types.
Genero BDL does not support the Informix
CLOB
and BLOB
types.
ORACLE
ORACLE provides CLOB
, BLOB
, and BFILE
data
types to store large text and binary data.
The ORACLE large object types are similar to Informix LOB types.
Solution
The ORACLE database interface can convert BDL TEXT
data to ORACLE
CLOB
and BYTE
data to ORACLE BLOB
.
Genero TEXT/BYTE
program variables have a limit of 2 gigabytes. Make sure that
the large object data does not exceed this limit.
The ORACLE BFILE
type is not supported by Genero BDL.
The
TEXT
and
BYTE
types translation can be controlled with the following FGLPROFILE
entries:dbi.database.dsname.ifxemul.datatype.text = {
true |
false }
dbi.database.dsname.ifxemul.datatype.byte = {
true |
false }
