RELOAD EXTERNAL DATA
RELOAD EXTERNAL DATA ( aField )
| Parameter | Type | Description | |
|---|---|---|---|
| aField | Text, Blob, Picture, Object | → | Field for which to set the storage location |
Description
The RELOAD EXTERNAL DATA command reloads the contents in memory of an external storage file associated with a BLOB, Picture, or Text type field.
This command is useful when the field of a record already loaded in memory is modified on the disk by another application (external storage files for fields are always writable). For example, a picture used in a Picture field can be modified by a graphic editor then saved on disk.
You then need to reload the data using the RELOAD EXTERNAL DATA command to update the contents of the field if it displayed in a form.
Note: The RELOAD EXTERNAL DATA command only works on a local 4D or on 4D Server. You cannot reload a field individually with 4D in remote mode. In this context, you have to reload all the records (using the LOAD RECORD command for example).
