SQL更新语句 - 尝试更新整个表错误

Question

我正在使用Derby数据库,我正在尝试更新其中一个表中的每一列.

我正在使用以下声明:

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完成了更新:

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

有更简单的方法来更新整个表吗？如果没有,我在这个陈述中做错了什么,因为我一直收到以下错误:

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

Answer 1

这个

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,用AND.替换.
