If you need to RTRIM() all the accounts of a particular customer, you can use a JOIN with your UPDATE statement as follows:

如果您需要RTRIM()特定客户的所有帐户,您可以使用JOIN和UPDATE语句,如下所示:

UPDATE
    accounts_table
INNER JOIN
    customers_table ON (accounts_table.user_id = customers_table.user_id)
SET 
    accountnumber = RTRIM(accountnumber)
WHERE
    customers_table.customer_id = 'customer id';

If you do not have many records in accounts_table, and you want to make sure that all the accountnumber values are trimmed, you can simply apply the trim to all the records as follows:

如果您在accounts_table中没有很多记录,并且您希望确保修剪所有帐户编号值,则只需将修剪应用于所有记录,如下所示:

UPDATE
    accounts_table
SET 
    accountnumber = TRIM(accountnumber);

#2

You would use TRIM and update.

您将使用TRIM并进行更新。

Just using this should do it.

只是使用它应该这样做。

UPDATE accountTable
SET ACCOUNTNUMBER = RTrim(ACCOUNTNUMBER)

#3

If you have foreign key constraints, then you may have to remove them whilst you make the modifications.

如果您有外键约束,那么您可能必须在进行修改时将其删除。

The following query will change the records in the accounts table:

以下查询将更改accounts表中的记录:

update accounts set accountnumber = rtrim(accountnumber);
