PostgresDB 2200B: Escape Character Conflict

What is PostgresDB 2200B: Escape Character Conflict

When encountering error 2200B: Escape Character Conflict in Postgres DB, execute the following actions:

Identify the query causing the error. Review the application logs or enable query logging in PostgreSQL to capture the problematic query.Once the query is identified, examine it for string literals or escape sequences that might be causing the conflict. Look for backslashes (\) used in the query, as they are common culprits.If the issue is due to a literal backslash, ensure that it is properly escaped. In PostgreSQL, you can escape a backslash by doubling it (\\).Run the corrected query directly in the PostgreSQL console to verify that the error is resolved. You can open the console by executing psql -U username -d dbname, replacing username with your PostgreSQL username and dbname with the name of your database.If step 3 doesn’t resolve the issue, the error might be related to the standard_conforming_strings setting. Check its value by running the query: SHOW standard_conforming_strings;. If the value is off, it affects how PostgreSQL interprets escape characters.To temporarily change standard_conforming_strings for your session to test if it resolves the issue, run: SET standard_conforming_strings = ON; Then, re-run your original query. If this resolves the issue, consider making this change permanent in your PostgreSQL configuration file (postgresql.conf) by setting standard_conforming_strings = on and restarting the database server.If none of the above steps resolves the issue, examine the use of escape characters in any custom functions or stored procedures involved in the query. Ensure that any dynamic SQL generation properly escapes characters as required.

Execute these steps methodically to diagnose and resolve the 2200B: Escape Character Conflict error in PostgreSQL.
