我有一个sql update语句,但我不明白为什么它不更新我的记录,它什么都不做,语法有什么问题吗?
private static final String strUpdatePerson =
"UPDATE APP.PERSON " +
"SET FIRSTNAME = ?, " +
" LASTNAME = ?, " +
" ADDRESS = ?, " +
" PHONE = ?, " +
" EMAIL = ?, " +
" INFO = ? " +
"WHERE ID = ?";
这非常令人困惑,因为没有给出错误,它执行更新但在数据库中没有任何更改。
编辑:
这是正在执行的查询:
stmtUpdateExistingRecord = dbConnection.prepareStatement(strUpdateCustomer);
stmtUpdateExistingRecord.clearParameters();
stmtUpdateExistingRecord.setString(1, record.firstName.toUpperCase());
stmtUpdateExistingRecord.setString(2, record.lastName.toUpperCase());
stmtUpdateExistingRecord.setString(3, record.Address);
stmtUpdateExistingRecord.setString(4, record.phoneNumber);
stmtUpdateExistingRecord.setString(5, record.email);
stmtUpdateExistingRecord.setString(6, record.info);
stmtUpdateExistingRecord.setInt(7, record.getID());
stmtUpdateExistingRecord.executeUpdate();
答案 0 :(得分:2)
您应该在 如果dbConnection.setAutoCommit(true);
之前致电executeUpdate()
,或者在dbConnection.commit();
之后致电executeUpdate()
dbConnection.getAutoCommit()
返回true,则表示您遇到了其他错误。你确定它没有抛出Exception
吗?
