    <p>I got a problem with <code>RecordStore</code> when I fetch it and put it into array I got multiple results.</p> <p>I mean when I have 3 records and fetch it by <code>enumerateRecords</code> then put it into <code>array[][]</code> and then fetch it again, I know that is wrong way to fetch again, but how can I add <code>resultset</code> of <code>recordstore</code> into <code>array[][]</code> and then fetch <code>resultset</code> of <code>array[][]</code>?</p> <p>My Code:</p> <pre><code> public Table showRs(){ String sID = null,sName = null,sTOE = null; hrs.openRecordStore(hrs.getRecordnameBasic()); //hrs.listofRecord(); RecordEnumeration re; try { re = hrs.getRcs().enumerateRecords(null, null, true); while(re.hasNextElement()){ byte[] recordBuffer = re.nextRecord(); String record = new String(recordBuffer); //ID int iID = record.indexOf(";"); sID = record.substring(0,iID); //Name int iName = record.indexOf(";", iID+1); sName = record.substring(iID + 1,iName); //Type of Est int iTOE = record.indexOf(";", iName + 1); sTOE = record.substring(iName + 1, iTOE); int rc = hrs.getRcs().getNumRecords(); tb = new Table(mf, this, "List of record"); TableCell cells[][] = new TableCell[rc][3]; for(int i = 0; i&lt; rc ; i++){ System.out.println("-------" + sID);

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
