Openedge progress - Can't escape single quote - Is this a bug?

Question

I am trying to run a simple query over jdbc ALTER TABLE Customer ALTER \"Cust-Name\" set PRO_DESCRIPTION 'Customer Name' This works perfectly well. But, when I have to set description as "Customer's Name", i.e, include a single quote - I am unable to get it to work.

I tried

ALTER TABLE Customer ALTER \"Cust-Name\" set PRO_DESCRIPTION 'Customer~'s Name'
ALTER TABLE Customer ALTER \"Cust-Name\" set PRO_DESCRIPTION 'Customer~~'s Name'
ALTER TABLE Customer ALTER \"Cust-Name\" set PRO_DESCRIPTION 'Customer\\'sName'
ALTER TABLE Customer ALTER \"Cust-Name\" set PRO_DESCRIPTION "Customer's Name"

Nothing works.

Answer 1

I don't know Progress, but the SQL standard is to duplicate the single quote:

'Customer''s Name'

Answer 2

While I was learning Progress I encountered a function called QUOTER that can be used in your situation.

QUOTER function

---

Converts the specified data type to CHARACTER and encloses the results in quotes when necessary.

The QUOTER function is intended for use in QUERY-PREPARE where a character predicate must be created from a concatenated list of string variables to form a WHERE clause. In order to process variables, screen values, and input values so that they are suitable for a query WHERE clause, it is often necessary to enclose them in quotes. For example, European-format decimals and character variables must always be enclosed in quotes. You can use the Quoter function to meet that requirement.
