Data types allowed in a fixed format

You can use the following data types when you are preparing a fixed format.


Data type	Description
Chars	ASCII format data
Short Unsigned Short Integer Unsigned Integer Long Integer Unsigned Long Float Double	The Machines description specifies the number of bytes required in fixed format for integers and floating-point values (see The Machines window.) When you select one of these data types, iploadsets the number of bytes.
Date	Date string
UNIX™ Date	A long integer interpreted as the system date from a UNIX™ system
Blob Length	The number of bytes of BYTE and TEXT (binary large object) that follow this record
Blob File	A file that contains BYTE and TEXT data
BLOB and CLOB	A file that contains smart large object (BLOB or CLOB) data
Simple LO Length	The number of bytes of simple large object data (BYTE and TEXT data) that follow this record
Simple LO File	The name of a file that contains a Simple LO data (BYTE and TEXT data)
INT8	An eight-byte integer type
SERIAL8	An eight-byte serial column
BIGINT	An ASCII character string or an eight-byte integer type
BIGSERIAL	An ASCII character string or an eight-byte integer type
Ext Type String	The ASCII representation of an extended data type (Ext Type) value
Ext Type String Length	The length of an ASCII Ext Type value. The Ext Type value follows at the end of the input/output record. Use Ext Type String Length data type if you have data that contains null UDT values.
Ext Type Binary	The binary representation of an Ext Type value
Ext Type Binary Length	The length of the binary representation of an Ext Type value. The binary value follows at the end of the input/output record. Use Ext Type Binary Length data type if you have data that contains null UDT values.

The HPL supports several data types under the Ext Type mechanism. As a result, the specific names of these data types do not appear in the data-type selection list. For the following data types, choose the appropriate Ext Type data type:

INT8
LVARCHAR
SERIAL8
BLOB
BOOLEAN
CLOB
Collection data types
Distinct data type
Opaque data types
Row types
