SQL Error: ORA-00933: SQL command not properly ended

Question

I am trying to update a record in oracle SQL developer by using Joins. Following is my query-

UPDATE system_info set field_value = \'NewValue\' 
FROM system_

Not exactly the case of actual context of this question, but this exception can be reproduced by the next query:

update users set dismissal_reason='he can't and don't want' where userid=123

Single quotes in words can't and don't broke the string. In case string have only one inside quote e.g. 'he don't want' oracle throws more relevant quoted string not properly terminated error, but in case of two SQL command not properly ended is thrown.

Summary: check your query for double single quotes.
