Storage

Core

Indicate whether a persistent storage table of the specified name is present and return its contents if present.

Name (string): The name of the persistent storage table. Case is not significant.

Value (table): Contents of the persistent storage table, which may be empty, either because the table is empty in persistent storage or because the table does not exist.

@found = Storage.Check(Name: "2018.Sept.AdobeUsers");
IF NOT (@found)
    SELECT "Table not found" AS Status;
ELSE
    @table = Storage.Get(Name: "2018.Sept.AdobeUsers");
    IF NOT (@table)
        SELECT "Table is empty" AS Status;
    ELSE
        SELECT "Table retrieved and has content" AS Status;
    ENDIF;
ENDIF;

This method can be used with the SCALE evaluate statement to abandon processing if the persistent storage table is not present.
