java - SQL 更新语句 - 尝试更新整个表错误

Question

我正在使用 Derby 数据库，并且正在尝试更新我的一个表中的每一列。

我正在使用以下语句：

String stmt = "UPDATE APP.DATAVAULT SET DID = ?, DTITLE = ?, DUNAME = ?, DPASS = ?, DSANSWER = ?, DPIN = ?, DURL = ?, DNOTES = ?, PID = ? WHERE DID = ?, DTITLE = ?, DUNAME = ?, DPASS = ?, DSANSWER = ?, DPIN = ?, DURL = ?, DNOTES = ?, PID = ?";

我之前使用以下语句进行了更新：

String stmt = "UPDATE APP.PERSON SET PSNAME = ? WHERE PID = ?";

有没有更简单的方法来更新整个表？如果不是，我在此声明中做错了什么，因为我不断收到以下错误：

Syntax error: Encountered "," at line 1, column 137.

Answer 1

这

WHERE DID = ?, DTITLE = ?, DUNAME = ?, DPASS = ?, DSANSWER = ?, DPIN = ?, DURL = ?, DNOTES = ?, PID = ?

应该是这个

WHERE DID = ? AND DTITLE = ? AND DUNAME = ? AND DPASS = ? AND DSANSWER = ? AND DPIN = ? AND DURL = ? AND DNOTES = ? AND PID = ?

所以替换,为AND.

Answer 2

应该添加多个子句，ANDnot with comma(,)。一定是WHERE DID = ? AND DTITLE = ? AND...

Answer 3

WHERE 子句中的逗号应该是 AND

String stmt = "UPDATE APP.DATAVAULT SET DID = ?, DTITLE = ?, DUNAME = ?, DPASS = ?, DSANSWER = ?, DPIN = ?, DURL = ?, DNOTES = ?, PID = ? WHERE DID = ? AND DTITLE = ? AND DUNAME = ? AND DPASS = ? AND DSANSWER = ? AND DPIN = ? AND DURL = ? AND DNOTES = ? AND PID = ?";
