SQL更新语句 - 尝试更新整个表错误

Question

我正在使用Derby数据库，而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 = ?";

之前我使用以下语句完成了更新：

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

是否有更简单的方法来更新整个表格？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

此

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,替换AND。

Answer 2

应添加多个子句AND而不是逗号（，）。必须是WHERE DID = ? AND DTITLE = ? AND...

Answer 3

WHERE子句中的逗号应为ANDs

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 = ?";
