How Can I Avoid Conflicts When Inserting Data into PostgreSQL Columns Named After Keywords?

Handling PostgreSQL Keyword Conflicts in INSERT Statements

PostgreSQL users may encounter insertion errors when dealing with columns named after reserved keywords (e.g., "year," "select"). The solution is to quote the column name using double quotes, explicitly identifying it as an identifier rather than a keyword.

For example:

INSERT INTO my_table (id, name, "year") VALUES (1, 'Example', 2024);

Notice the double quotes around "year". This tells PostgreSQL to treat "year" as a column name, preventing conflicts with the SQL keyword year. This approach ensures successful data insertion.

The PostgreSQL documentation clarifies that quoted identifiers (delimited by double quotes) are always interpreted as identifiers, never as keywords. This allows the use of potentially problematic words like "select" or "year" as column names without causing parsing issues.
