Remove Record object record from Recordset (Recordset class)


RemoveRecord removes the record in a Record object from the records in an existing Recordset object. It provides functionality identical to the User Language Remove Record statement, but it does so for Recordset objects.

Syntax

recordset:RemoveRecord( record)

Syntax terms

%target A non-null Recordset object variable.
recordObject A non-null Record object, which must have the same file context as %target.

Usage notes

  • Since RemoveRecord never adds a record to a Recordset, there are no lock strength requirements for the method object or the input object.
  • If the Record object argument of RemoveRecord is null, the request is cancelled.

Example

In the following example, records not meeting a certain criterion are removed from a Recordset:

%mailList is object recordSet in file customers find records to %mailList status = 'ACTIVE' end find for each record in %mailList if totalPurchase lt 100 then %mailList:removeRecord(currentRecord) end if end find

With version 6.8 of Sirius Mods and earlier, you must specify the class name or an object variable before the CurrentRecord method name; for example:

%mailList:removeRecord( -  %(Record in File customers):currentRecord)
