ORA-00936錯誤是Oracle數據庫中的一個常見錯誤，它表示SQL查詢中缺少了一個表達式。這通常是由于以下原因之一引起的：
錯誤示例：SELECT FROM table_name;
正確示例：SELECT column_name FROM table_name;
錯誤示例：SELECT * FROM table_name WHERE column_name;
正確示例：SELECT * FROM table_name WHERE column_name = ‘value’;
錯誤示例：INSERT INTO table_name VALUES ();
正確示例：INSERT INTO table_name (column1, column2) VALUES (value1, value2);
錯誤示例：UPDATE table_name SET WHERE column_name;
正確示例：UPDATE table_name SET column_name = ‘value’ WHERE condition;
錯誤示例：SELECT column_name FROM table_name GROUP BY;
正確示例：SELECT column_name FROM table_name GROUP BY column_name;
要解決ORA-00936錯誤，需要檢查SQL查詢語句中是否存在上述問題，并進行相應的修正。
