Why does Postgres return 'column '5837-2016-08-24_09-12-22' does not exist,' and how can I fix it?

Resolving PostgreSQL error: "Column "5837-2016-08-24_09-12-22" does not exist"

When encountering this error message, it is important to note that column names should be enclosed in double quotes, while string constants need to be enclosed in single quotes. In this case, the error occurred because the value "5837-2016-08-24_09-12-22" was mistaken for a column name instead of a string literal.

To resolve this issue, you can correct the SQL statement as follows:

INSERT INTO config_change_log(last_config_version, is_done, change_description )
VALUES('5837-2016-08-24_09-12-22', false, '{ ''key'':''value''}');

By surrounding the string constant with single quotes, it will be correctly recognized as a value rather than a column name.

Alternatively, you can escape single quotes in your data by doubling them, as in the following example:

INSERT INTO config_change_log(last_config_version, is_done, change_description )
VALUES('5837-2016-08-24_09-12-22', false, '{ "key":"value"}');

This approach ensures that single quotes in the change_description column are interpreted as part of the string value rather than causing a syntax error.

Remember, it is always recommended to use single quotes for string constants and double quotes for column names to avoid potential conflicts and ensure correct syntax. By implementing these corrections, you should be able to successfully insert data into your PostgreSQL database without encountering "column does not exist" errors.
