What is

PostgresDB 23502: Not Null Violation

 ?

When encountering a 23502: Not Null Violation error in a PostgreSQL database, the user should take the following immediate actions:

  1. Identify the Table and Column:
    • The error message usually specifies which table and column are causing the not null violation. Note down these details.
  2. Check the Insert/Update Query:
    • Review the SQL query (INSERT or UPDATE) that led to the error. Ensure it includes a value for the column mentioned in the error message.
  3. Verify Column Constraints:
    • Run the following SQL command to inspect the constraints, especially the NOT NULL constraint, on the problematic column:
    • SELECT column_name, is_nullable
      FROM information_schema.columns
      WHERE table_name = 'your_table_name' AND column_name = 'your_column_name';
    • Replace 'your_table_name' and 'your_column_name' with the actual table and column names.
  4. Adjust the Query:
    • If the problematic column was unintentionally omitted or provided with a NULL value, modify your SQL query to include a valid, non-null value for this column.
  5. Check for DEFAULT Values:
    • If the column is supposed to have a default value, check if it is properly set by running:
    • SELECT column_name, column_default
      FROM information_schema.columns
      WHERE table_name = 'your_table_name' AND column_name = 'your_column_name';
    • If there is no default value, or it's not suitable, you may need to explicitly provide a value in your query.
  6. Examine Application Logic:
    • If your query is generated or modified by application logic, review the relevant code sections to ensure they correctly handle the column in question, particularly for INSERT or UPDATE operations.
  7. Run a Test Insert/Update:
    • After understanding the constraints and adjusting your query or application logic, perform a test INSERT or UPDATE operation with a valid, non-null value for the problematic column to confirm the issue is resolved.

These steps focus on identifying and correcting the immediate cause of the 23502: Not Null Violation error directly related to specific SQL operations and column constraints.
