我試圖

sb.append(" and T1.OU_TYPE_CD <> /'NOC/' "); 
sb.append(" and T1.OU_TYPE_CD <> ''NOC'' "); 
sb.append(" and T1.OU_TYPE_CD <> 'NOC' ");

沒有工作。我在這裏做錯了什麼？ T1.OU_TYPE_CD是列名，NOC是其中的值。我想檢查T1.OU_TYPE_CD的值是NOT NOC。

你能打印出字符串嗎？ –

你確定問題出在那裏嗎？那之後呢？ –

你不需要雙單引號括起來NOC：

sb.append(" and T1.OU_TYPE_CD <> 'NOC' ");

您的外字符串分隔符是一個雙引號，所以沒有必要逃避單引號。

試過，不工作！ – user3232895

@ user3232895。。。它不應該是同一個錯誤，因爲在這個查詢中'NOC'不能是列名。 –

@ Lionoff ......不幸的是同樣的錯誤。無效的列名稱NOC！ – user3232895

列名不需要''：

sb.append(" and T1.OU_TYPE_CD <> NOC ");

編輯：

編譯器被解釋爲NOC列名。如果NOC是string值，我認爲您的問題將是一個轉義問題。

嘗試：

sb.append(" and T1.OU_TYPE_CD <> \'NOC\' ");

或本：

sb.append(" and T1.OU_TYPE_CD NOT IN ('NOC') ");

或直接設置一個aux字符串：

String aux = " and T1.OU_TYPE_CD <> 'NOC' "; 
sb.append(aux);

它不是列名，NOC是T1.OU_TYPE_CD列中的數據 – user3232895

這應該有工作。 ''和'。'''''''）;;

您確定您收到相同的錯誤訊息嗎？
