When encountering the error 42602: Invalid name from PostgreSQL, the user should immediately check the SQL command or query that caused this error for any identifiers (such as table names, column names, or alias names) that do not adhere to PostgreSQL's naming conventions. Identifiers should not begin with a digit, contain whitespace, or special characters that are not allowed unless they are quoted.
"My Column").SELECT * FROM some invalid name;
SELECT * FROM "some invalid name";
SELECT * FROM your_table_name LIMIT 1;
To access the PostgreSQL logs, the command or method varies depending on the operating system and PostgreSQL installation, but a common approach is to check the directory specified by the log_directory configuration parameter, which can be found by running:
SHOW log_directory;
These steps focus on immediate actions to identify and correct the issue related to the 42602 error code without requiring deep database administration knowledge or access.
