the class ProjectColumnList method bind.

public void bind(JaqyResultSet rs, JaqyInterpreter interpreter) throws SQLException {
    int numCols = m_columnList.size();

    JaqyHelper helper = rs.getHelper();
    for (int i = 0; i < numCols; ++i) {
        ProjectColumn column = m_columnList.get(i);
        int index = rs.findColumn(column.name);
        columnInfos[i] = ResultSetMetaDataUtils.getColumnInfo(rsmd, index, helper);
