In my database (version 8.0.2 ) I have a value stored as "([t]{0,1})^(t?)+$\" (Please note that this value uses many characters which have special meaning in regular expression)
Earlier I had a query which used to fetch this value SELECT "Topic" FROM "schema1"."Topics" WHERE "Topic" similar to '\\(\\[t\\]{0,1}\\)\\^\\(t?\\)\\+\\$\\\\' ORDER BY "Topic" This query worked fine and did return the matching value stored in database .
Later on to support, case insensitive value search, I modified the query to SELECT "Topic" FROM "schema1"."Topics" WHERE "Topic" ~* '\\(\\[t\\]{0,1}\\)\\^\\(t?\\)\\+\\$\\\\' ORDER BY "Topic"
(Please note that I just replaced similar to with ~*)
The new query does not work. Please let me know where I am making a mistake. If there are other approaches to go about case insensitive pattern matching in query, please provide pointers to that.
Thanks in advance.
