JtextField에서 java / jdbc를 사용하여 매개 변수 전달

3 가지 키 값으로 더비 데이터베이스를 검색 할 수 있어야합니다. GUI가 설정되어 있고 데이터베이스의 데이터로 채울 수 있습니다. 어느 방향 으로든 스크롤 할 수 있도록 설정했습니다. 내가 가진 문제는 내 쿼리가 실패한 키 필드 중 하나의 특정 검색을 수행하는 방법을 만들 때입니다. 다음은 검색을 용이하게하기 위해 사용하려는 방법입니다. 문을 사용하고 변수를 String 문에 연결하려고 시도했으며 준비된 문을 사용하고 변수를 바인딩 해 보았습니다. 어느 쪽도 일을 할 수 없습니다. 오류가 발생한 코드에 표시했습니다.

public static void Search(){
    String idField = InitGUI.getidField().getText();
    String sql = ("SELECT * FROM MYDB.Employee WHERE Employee ID = '"+idField +"'");

    try {

//      prepStat = dbCon.prepareStatement(sql);
//      prepStat.setString(1, idField);
//      rs = prepStat.executeQuery();
    rs = stmt.executeQuery(sql);     <== This is where the error occurs.
    SqlStatements.SearchResult(rs.getRow());
    } catch (SQLException e) {

        e.printStackTrace();
    }
}
