Steps through a specified number of records and retrieves a record.
[Steps :=] RecordRef.NEXT([Steps])
- Type: RecordRef The RecordRef that refers to the record that you want to use as the starting point for the steps. The function returns 0 if no table is selected.
- Type: Integer Defines the direction of the search and how many records to step over. If this parameter is greater than zero, the function will search the number of records specified in Steps forward in the table. If this parameter is less than zero, the function will search the number of records specified in Steps backward in the table. If this parameter is 0, no records are stepped over. If you do not specify this parameter, the function finds the next record.
Property Value/Return Value
Returns the number of records inspected which meet the criteria of any filters and the current key. This value can be less than Steps, depending on the number of records in the table. If the table is empty, zero is returned and the record is not changed.
This function locates a record positioned a given number of steps forward or backward from the record specified by RecordRef. Movement through the table is governed by the filters and the current key associated with the records. The fields in the record which will be compared with the current key fields must contain appropriate values before the function is called.
This function works the same as the NEXT Function (Record).
The following example opens the Customer table as a RecordRef object, creates a reference to the first (No.) field, and stores the reference in the MyFieldRef variable. The SETRANGE function sets a filter that selects all records from 10000 to 40000 in the No. field. The FIND Function (RecordRef) searches and selects the first record in the filter and counts the number of records that are found. The number of records is stored in the Count variable. The process is repeated by looping through all the records in the filter until no more records are found. The NEXT function steps through the records and finds the next record because no value is specified for the Steps parameter. The number of records that are found in the range is stored in the Count variable and displayed in a message box. This example requires that you create the following variables and text constant in the C/AL Globals windows.
|Text constant||ENU value|
%1 records were retrieved.
CustomerRecref.OPEN(DATABASE::Customer); MyFieldRef := CustomerRecref.FIELD(1); MyFieldRef.SETRANGE('10000' , '40000'); Count := 0; IF CustomerRecref.FIND('-') THEN REPEAT Count := Count + 1; UNTIL CustomerRecref.NEXT = 0; MESSAGE(Text000 , Count);
