exist method on temporary table

[ist]

Hi,
I'm trying to make exist method on temporary table something like this...

static boolean exist(MyTempTable _tempTable,
                             RefTableId      _tableId,
                             RefRecId        _recId)
{
    return _tableid && _recId && (select RecId from _tempTable
                                                   where _tempTable.TableNum = _tableId
                                                       && _tempTable.RecordNo = _recId
             ).RecId != 0;
}

Just like find() methods on a temp table, I pass the temporary table reference as parameter, but compiler throw an error "The table _tempTable does not exist".

Any ideas what's the problem?

                             RefRecId        _recId)
{
    if(! _tableid || !_recId)
        return false;

    select RecId from _tempTable
    where _tempTable.TableNum = _tableId
        && _tempTable.RecordNo = _recId

    return _tempTable.RecId != 0;
}

Just to make it clear for you. See the "Select statement" article in the Dev Guide:

Цитата:

Field select

It is also possible to use a select statement in a lookup on a field. After a select statement that fetched a record in a table, you can write .field name to reference a field in the table.

Notice the difference between the normal select and the field select. The field select operates directly on a table, whereas the select statement operates on a table variable.
