MySQL替换列中的字符

Question

I would like to replace all occurences of 's with s in myTable's name column. I tried REPLACE but it replaces all records. I want to do it for some customers.

Note: Customer is foreign key in myTable.

Thanks in advance

Update:

I tried some queries REPLACE(name, "'s", "s") from data where cust_id = 1 but this doesn't work

From one of questions I tried SELECT REPLACE(name, "'s", "s") from data where cust_id = 1 . This is replacing all records in table

Answer 1

A simple replace across all records in the table can be done with:

 UPDATE myTable
 set    name = REPLACE(name, '\'s', 's')

If you want to filter the records to be updated from another table, then you can do something like

 UPDATE myTable
 LEFT JOIN CustomerTable ON myTable.Customer = CustomerTable.Customer
 SET    name = REPLACE(name, '\'s', 's')
 WHERE  CustomerTable.Field > SomeCondition <== Replace with what you need.
