FINDSET Function (Record)

Мақала
06/05/2016

Finds a set of records in a table based on the current key and filter.

Syntax

  
[Ok :=] Record.FINDSET([ForUpdate][, UpdateKey])

Parameters

Record
Type: Record

If the record is found, then the record is returned in this parameter and any FlowFields in the record are set to zero. You must update the FlowFields by using the CALCFIELDS Function (Record).

ForUpdate
Type: Boolean

Set this parameter to true if you want to modify any records in the set; otherwise, set the parameter to false.

If you set this parameter to true, then the LOCKTABLE Function (Record) is immediately run on the table before the records are read.

If you set this parameter to false, then you can still modify the records in the set, but these updates will not be performed optimally.

The default value is false.

UpdateKey
Type: Boolean

Set this parameter to true if you want to modify any field value within the current key.

This parameter only applies if the ForUpdate parameter is true.

If you set this parameter to false, then you can still modify the records in the set, but these updates will not be performed optimally.

The default value is false.

Property Value/Return Value

Type: Boolean

true if the record set was found; otherwise, false.

If you omit this optional return value and if the record cannot be found, then a run-time error occurs. If you include a return value, then you must handle any errors.

Remarks

You should use this function only when you explicitly want to loop through a recordset. You should only use this function in combination with REPEAT.. UNTIL.

Example 1

This example shows how to use the FINDSET function to loop through a set without updating it. This example requires that have a CopyLine function and that you create the following variable.

Variable name	DataType	Subtype
SalesLine	Record	Sales Line

SalesLine.SETFILTER("Purch. Order Line No.",'<>0');  
IF SalesLine.FINDSET THEN BEGIN  
  REPEAT  
    CopyLine(SalesLine);  
  UNTIL SalesLine.NEXT = 0;  
END;

Example 2

This example shows how to use the FINDSET function to loop through a set and update a field that is not within the current key. This example requires that you create the following variables.

Variable name	DataType	Subtype
SalesLine	Record	Sales Line
DocumentType	Option	Not applicable
DocumentNo	Code	Not applicable

This example assumes that you have assigned values to the DocumentType and DocumentNo variables and that you have a GetNewLocation function, which returns a value that is a Code data type.

SalesLine.SETRANGE("Document Type",DocumentType);  
SalesLine.SETRANGE("Document No.",DocumentNo);  
IF SalesLine.FINDSET(TRUE, FALSE) THEN BEGIN  
  REPEAT  
    SalesLine."Location Code" := GetNewLocation(SalesLine);  
    SalesLine.MODIFY;  
  UNTIL SalesLine.NEXT = 0;  
END;

Example 3

This example shows how to use the FINDSET function to loop through a set and update a field that is within the current key. This example requires that you create the following variables.

Variable name	DataType	Subtype
SalesShptLine	Record	Sales Shipment Line
SalesShptLine2	Record	Sales Shipment Line
SalesLine	Record	Sales Line

SalesShptLine.SETCURRENTKEY("Order No.","Order Line No.");  
SalesShptLine.SETRANGE("Order No.",SalesLine."Document No.");  
SalesShptLine.SETRANGE("Order Line No.",SalesLine."Line No.");  
IF SalesShptLine.FINDSET(TRUE, TRUE) THEN BEGIN  
  REPEAT  
    SalesShptLine2 := SalesShptLine;  
    SalesShptLine2."Order Line No." := SalesShptLine."Order Line No." + 10000;  
    SalesShptLine2.MODIFY;  
  UNTIL SalesShptLine.NEXT = 0;  
END;
