filename.dif
This parameter defines the file name of the target file with exported data using the Data Interchange Format. The file extension must be dif.
SELECT clause
Use the SELECT command to identify rows of data from a table or view.
OPTION
ACTION
Defines the default action which will be processed after export is complete, for example, to open the target export file in view/edit mode or send this exported file by email as attachment. Available Parameter: OPENVIEW
ADD_UTF8_BOM
Specifies whether to add a UTF8 BOM to an exported UTF8 string. Available Parameters: ON / OFF
BLANK_IF_NULL
If ON, will export NULL values as blank values. If OFF, will export NULL values as the database NULL setting. The default is set to OFF. Available Parameters: ON / OFF
BLANK_IF_ZERO
If ON, will export zero values as blank values. If OFF, will export zero values as zero. The default is set to OFF. Available Parameters: ON / OFF
DATASET_FIELD_ORDER
Specifies the export will follow the SELECT clause column order, rather than the field order in the specification file, when a specification file is used as an OPTION parameter. The default is set to OFF. Available Parameters: ON / OFF
MESSAGES
If ON, during export process some messages will be displayed such as -ERROR- messages, if any. If OFF, the entire export process will be in "silent" mode. Available Parameters: ON / OFF
NO_UNICODE_CONVERSION
Exports Unicode data as a UTF8 string to fit in the target field, ensuring no data is lost. If OFF, the Unicode data will be converted to ANSI and characters from source that is higher than 0x127 will become ‘?’. As not all target formats support Unicode and this field is for cases when source is Unicode and destination is normal text field. Available Parameters: ON / OFF
ROWS_PER_FILE
Specifies if the records are broken up into separate files based on the quantity of records in each file. If this parameter is not zero, multiple files may be generated.
SHOW_PROGRESS
Indicates whether to display status dialog during export process. Set SHOW_PROGRESS to ON if you wish to show an animated status dialog during the export process. Set SHOW_PROGRESS to OFF if you wish to export data without animated status dialog. Available Parameters: ON / OFF
SPECIFICATION_FILE_NAME
This parameter is used to load a prepared specification with all pre-defined settings for exporting. The export must be performed once using the graphic user interface "Export Wizard" and saved using the "Specifications.." button. The specifications will be stored in a file with the .RGW file extension. The .RGW file acts as a set of default values. Any value in the .RGW file will be overwritten by the same parameter specifically assigned by an OPTION parameter. Since the input file name is required in the GATEWAY command, the input file name in the .RGW will always be overwritten.
Examples:
GATEWAY EXPORT DIF D:\DataStore\Employee.DIF +
SELECT * FROM Employee WHERE EmpStatus = 'Active' +
OPTION SHOW_PROGRESS ON|MESSAGES ON
GATEWAY EXPORT DIF D:\DataStore\Contacts.DIF +
SELECT * FROM Contacts +
OPTION BLANK_IF_ZERO ON|MESSAGES OFF
