| Note | This command is defined in a header file and will be preprocessed by the X# preprocessor to a function call. If you disable the standard header (-nostddefs) files then this command will not be available. If you tell the compiler to use a different standard header file (-stddef ) then this command may also be not available |
Purpose
Restore records marked for deletion in the current work area.
Syntax
RECALL [<Scope>] [WHILE <lCondition>] [FOR <lCondition>] [[IN|ALIAS] <workarea>
Arguments
| <Scope> | The portion of the current database file to process. The default is all visible records. Scope is one or more clauses of: [NEXT <NEXT>] Optionally specifies the number of records to process starting with the first record of the source file. [RECORD <rec>] An optional record ID If specified, the processing begins with this data record in the source file. [<rest:REST>] The option REST specifies whether records are sequentially searched only from the current up to the last record. If a condition is specified, the option ALL is the default value. [ALL] The option ALL specifies that all records from the source file are imported. This is the default setting. |
| WHILE <lCondition> | A condition that each visible record within the scope must meet, starting with the current record. As soon as the while condition fails, the process terminates. If no <Scope> is specified, having a while condition changes the default scope to the rest of the visible records in the file. |
| FOR <lCondition> | A condition that each visible record within the scope must meet in order to be processed. If a record does not meet the specified condition, it is ignored and the next visible record is processed. If no <Scope> or WHILE clause is specified, having a for condition changes the default scope to all visible records. |
| IN|ALIAS <workarea> | Specifies the work area for which the operation must be performed |
RECALL is the inverse of the DELETE command. If SetDeleted() is TRUE, RECALL can restore the current record or a specific record if you specify a RECORD scope.
Important! Once you PACK a database file, all marked records are physically removed from the file and cannot be recalled.
Shared mode: For a shared database, this command requires all records that it operates on to be locked. You can accomplish this using one or more record locks or a file lock, depending on the scope of the command.
Examples
