Escape keyword-like column names in PostgreSQL: double quote solution

Understand the correct way to handle keyword-like column names (e.g. "year") in PostgreSQL to avoid parsing errors and ensure seamless database operations. Column names that resemble keywords can cause problems in queries.

Question:

Inserting values ​​into a column named "year" using a standard INSERT query may cause errors near the "year" keyword.

Solution:

Simply enclose keyword-like column names in double quotes to distinguish them as identifiers instead of keywords. This ensures that the database interprets it correctly.

For example, the following query sets the value of the "year" column:

INSERT INTO table (id, name, "year") VALUES ( ... );

Instructions:

According to the PostgreSQL documentation, double-quoted delimited identifiers are always treated as identifiers, not keywords. This allows us to use keyword-like column names in queries without causing errors.

By using the double quote escaping mechanism, you can efficiently handle keyword-like column names in PostgreSQL, ensuring precise data manipulation and preventing potential syntax errors.
