How to resolve Error 42803 PostgreSQL

According to our experts, error 42803 in PostgreSQL indicates an”undefined_column” error. In other words, the error is due to an incorrect column name used in the SQL statement.

For instance, if we try to select a non-existing column in the table, we are likely to run into error 42803 in PostgreSQL.

One way to resolve this error is by verifying the name of the column and ensuring no spelling errors have crept in. It is also a good idea to verify the case sensitivity of the column name. Especially since PostgreSQL is case-sensitive. Additionally, in case the column is missing in the table, we can add the column using the ALTER TABLE statement as seen below:

ALTER TABLE table_name
ADD COLUMN new_column_name column_type;

Our experts have compiled this list of troubleshooting tips to help you resolve this error:

• Check for typos:

  Look for spelling mistakes or typos in the SQL statement.
• Check the spelling of the column name:

  Verify that the column name is spelled correctly.
• Add the missing column to the table:

  In case the column is missing from the table, we can add it with the ALTER TABLE statement.
• Check the data type of the column:

  Our experts recommend checking if the data type specified for the column matches the data that will be stored in it.
• Check for reserved keywords:

  In case we used a reserved keyword in PostgreSQL as the column name, we are likely to run into error 42803.
