MS Access While Loop Skips first record


MS Access While Loop Skips first record

To fix this issue I finally got this to work!
Wayne's suggestion of moving the code from the sub form "Current" event to the buttons "Click" event was very helpful and got me on the right path.
code :
Private Sub SchedEmailButton_Click()

Dim rst As Object 'DAO.Recordset    <-- For some reason unknown to me the code didn't like declaring as a "DAO.Recordset"

Set rst = Me.FacEmailingList2.Form.Recordset

With rst
            .MoveFirst
            Do While Not .EOF
                SchedEmail
                .MoveNext
            Loop
        End With
        Set rst = Nothing
RunCommand acCmdRecordsGoToNext
DoCmd.GoToRecord record:=acNext
DoCmd.GoToRecord , , acNext

skips a record and uses the previous record data

it should still fix some issue You are mixing up two ways of handling cursors - explicit and implicit CURSOR FOR loops. You can compare the examples linked from that syntax page.
The FOR emp_record IN sal_cursor method automatically fetches each row into the emp_record variable. Your explicit FETCH then reads the next record. (I'm slightly surprised it doesn't complain about it).
code :
SET SERVEROUTPUT ON
DECLARE
CURSOR sal_cursor IS
    SELECT ename, sal
     FROM EMP
FOR UPDATE OF sal NOWAIT;
    V_sal   emp.sal%TYPE;
BEGIN
    FOR emp_record IN sal_cursor
LOOP
    IF (emp_record.sal <= 1000) THEN
        v_sal := emp_record.sal * 1.06;
    ELSIF emp_record.sal > 1000 AND emp_record.sal <= 3000 THEN 
        v_sal := emp_record.sal * 1.08;
    ELSE
        v_sal := emp_record.sal * 1.12;
    END IF;

    UPDATE emp
    SET EMP.sal = v_sal
    WHERE CURRENT OF sal_cursor;

    DBMS_OUTPUT.PUT_LINE(emp_record.ename || ', you just got an n percent raise
    and your new salary is ' || v_sal);
END LOOP;
DBMS_OUTPUT.PUT_LINE('He, he, he... just kidding!');
ROLLBACK;
END;

To fix the issue you can do You could pass in the parent as another parameter to the Iterate method.
code :
var records = [{
  "name": "Node-1",
  "nodes": [{
    "name": "Node-1-1",
    "parentName": null,
    "nodes": [{
      "name": "Node-1-1-1",
      "parentName": null,
      "nodes": []
    }]
  }]
}];
Iterate(records);

function Iterate(nodes, parent) {
  nodes.forEach(function(node) {
    if (parent) {
      node.parentName = parent.name;
    }
    if (node.nodes) {
      Iterate(node.nodes, node);
    }
  });
}

console.log(records);

This might help you I would like to loop though a recordset and figure out if there was a significan change in the value e.g. +/-10% from one record to the orther. My problem is that I dont know how to refer to the previous record... or to compare it with the next..... , It could be something like this:
code :
Dim CurrentPrice  As Currency
Dim PreviousPrice As Currency

rs1.MoveFirst

Do Until rs1.EOF
    CurrentPrice = rs1!Price.Value
    If PreviousPrice > 0 Then
       If CurrentPrice / PreviousPrice >= 1.1 Or
           CurrentPrice / PreviousPrice <= 0.9 Then
           rs1.Edit 
               rs1!Comments.Value = "Check if Index is correct"
           rs1.Update
       End If 
    End If
    PreviousPrice = CurrentPrice
    rs1.MoveNext
Loop

rs1.Close

it should still fix some issue You are calling itemReader.read() in the queryItemReader method. This is the cause of your issue.
Spring Batch will call lifecycle methods (open, update, close) on the item reader/writer so you don't have to call them yourself. In your case, the bean definition of the item reader should be something like:
code :
@Bean("query1ItemReader")
protected ItemReader<Query1> queryItemReader() throws Exception {
   final FileSystemResource resource = new FileSystemResource("input_query1.csv");
   FlatFileItemReader<Query1> itemReader;
   DefaultLineMapper<Query1> lineMapper;

   itemReader = new FlatFileItemReader<Query1>();
   lineMapper = new DefaultLineMapper<Query1>();
   itemReader.setResource(resource);
   lineMapper.setLineTokenizer(new DelimitedLineTokenizer());
   lineMapper.setFieldSetMapper(new Query1Config() .new QueryFieldSetMapper());
   itemReader.setLineMapper(lineMapper);
   return itemReader;
}
