你不需要SET为每列：

MySQL UPDATE SYNTAX：

UPDATE [LOW_PRIORITY] [IGNORE] table_reference 
    SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ... 
    [WHERE where_condition] 
    [ORDER BY ...] 
    [LIMIT row_count] 

String insert = "UPDATE PPN_WORKFLOW SET P1_F_Date = ?, P1_Completed = ?, 
C2_S_Date = ? WHERE ERF_No = ?";

你不能这样设置，你需要改变语法。一次SET足够

UPDATE PPN_WORKFLOW SET P1_F_Date = ?, P1_Completed = ?..... where condition

你有一个SET每个列名，您只需用逗号分隔的列和使用SET只有一次，看语法here：

UPDATE table_name 
SET column1=value, column2=value2,... 
WHERE some_column=some_value

您的SQL更新语句的语法wrong.Do把'SET' for each column in the query, you only do it at the first column

改变它

String insert = "UPDATE PPN_WORKFLOW SET P1_F_Date = ?, P1_Completed = ?, C2_S_Date = ? WHERE ERF_No = ?"; 
      stmt = conn.prepareStatement(insert); 
      stmt.setDate(1, date); 
      stmt.setInt(2, 1); 
      stmt.setDate(3, date); 
      stmt.setInt(4, erf_no); 
      stmt.executeUpdate();

继承人syntax for you reference
