Inserting with RecordInsertList

Posted on by junior AX 1,552
Hi,

I have a customized table with the following properties:
cache lookup: NotInTTS
Table Group: Transaction
AllowRowVersionChangeTracking: Yes
ValidTimeStateFieldType: None
The insert method doesn't have any code
 
Currently I'm inserting to this table using RecordInsertList  via batch. However i can see that records are being inserted to the table even though the batch is still executing. And the number of records inserted increases each certain amount of time. So it seems InsertToDatabase is not inserting eveything at once, it's inserting each group together. I'm currently importing more than 100,000 record.  At first the were around 240 records then i selected the table in SQL and they suddenly became 790, then 1370 etc..
Shouldn't it insert them all at once or is this normal? or is there a fallback?

i'll put the code in the first comment so that the code appears clearly

    That's correct - the purpose of RecordInsertList is not holding all records in memory and insert them at once. It inserts records in smaller chunks automatically; insertToDatabase() is used at the end to process remaining records that haven't been inserted yet.
     
    If you aren't sure how something should work, you can look into documentation: RecordInsertList Class.

    Imagine code starts with run method 
    class x extends classZBatch
{
  private RecordInsertList  recordInsertList = new RecordInsertList(tableNum(TableA));

  public void run()
  {
    this.process();
    this.postProcess();
  }

  public void postProcess() {

    recordInsertList.insertDatabase();
  }

  void process() 
  {
    str line;
    const str fieldDelimiter = '\r\n';
    const str recordDelimiter = '\r\n';
    importFile.inFieldDelimiter(fieldDelimiter);
    importFile.inRecordDelimiter(recordDelimiter);
    while (importFile.status() == IO_Status::Ok)
    {
      line = conPeek(importFile.read(), 1);

      ttsbegin;

      this.processLine(line);

      ttscommit;

    }
  }
  protected void processLine(str _line) 
  {
    ClassA process = classA::newFromEnumX(EnumX::First);
    process.insertTableA(_line);
    recordInsertList = process.getRecordInsertList();
  }
}


abstract class classA
{
    private TableA   tableA;

    private RecordInsertList recordInsertList = new RecordInsertList(tableNum(TableA));


    final public void insertTableA(str _line)
    {

        tableA.clear();
        // logic to fill table A
        
        recordInsertList.add(tableA);

    }


    public static ClassA newFromEnumX(EnumX _enumX)
    {
        EnumXAtrribute enumXAttribute = new EnumXAtrribute(_enumX);
        return SysExtensionAppClassFactory::getClassFromSysAttribute(classStr(ClassA), enumXAttribute);
    }


    public RecordInsertList getRecordInsertList()
    {
        return recordInsertList;
    }


}


class EnumXAtrribute extends SysAttribute implements SysExtensionIAttribute
{
    EnumX enumX;

    public void new(EnumX _enumX)
    {
        super();

        enumX = _enumX;
    }

    public str parmCacheKey()
    {
        return classStr(EnumXAtrribute) + ';'+ int2str(enum2int(enumX));
    }

    public boolean useSingleton()
    {
        return true;
    }

}
}
