Examples of org.apache.empire.db.DBTableColumn

org.apache.empire.db.DBTableColumn
This class represent one column of a table. It contains all properties of this columns (e.g. the column width).

        {
            DBTable table = seqtabs.next();
            Iterator<DBColumn> cols = table.getColumns().iterator();
            while (cols.hasNext())

                {
                    createSequence(db, c, script);
