<Source>.DeclareExternal (Function) In french: <Source>.DéclareExterne
Not available with this kind of connection
Temporarily imports into the current analysis the description of a data file from an existing HFSQL data file. This data file is opened. To no longer use this File Description, call <Source>.CancelDeclaration.
Remarks - All the HFSQL functions can be used on the imported data file except for the integrity management.
- You can import as many descriptions as necessary.
- This function can be used with data files in XML format.
- To use <Source>.DeclareExternal in a stored procedure:
- the relative path of the data file must be specified in relation to the directory of the database containing the stored procedure. The path must include the name and extension of the data file.
- don't use a connection: the current database containing the stored procedure will be used.
- By default, if the current project:
- is associated with an analysis, the lock mode applied to the data files is the multi-user mode (the files are not locked when they are opened and they can be accessed by the other applications).
- is not associated with an analysis, the blocking mode applied to data files is single-user: files are completely blocked from reading and writing as soon as they are opened.. This mode prevents the other applications from accessing the files already opened by the current application.
