[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2674) Query using Escape syntax in LIKE expression with PostgresSQL 8.2 results in PSQLException: The column index is out of range
[

]
Shelly McGowan commented on HHH-2674:
-------------------------------------
This issue can be resolved with a PostgreSQL setting standard_conforming_strings to true:
standard_conforming_strings (boolean)
This controls whether ordinary string literals ('...') treat backslashes
literally, as specified in the SQL standard. The default is currently off, causing
PostgreSQL to have its historical behavior of treating backslashes as escape characters.
The default will change to on in a future release to improve compatibility with the
standard. Applications can check this parameter to determine how string literals will be
processed. The presence of this parameter can also be taken as an indication that the
escape string syntax (E'...') is supported. Escape string syntax should be used if
an application desires backslashes to be treated as escape characters.
per database parameter (http://www.postgresql.org/docs/8.2/static/sql-alterdatabase.html)
or per user (http://www.postgresql.org/docs/8.2/static/sql-alteruser.html
postgres=# ALTER USER username SET standard_conforming_strings = true;
postgres=> show standard_conforming_strings;
