| Goal | INSERT statements shouldn't be sensitive towards the order of columns. If one changes the order of columns in a table then these statements must be rewritten. Otherwise the code will not work or works incorrectly. |
|---|---|
| Notes | Refers to the column pg_proc.prokind and thus works starting from PostgreSQL 11. In the returned body of routine the query replaces each newline character with the line break (br) tag for the better readability in case the query result is displayed in a web browser. There could be multiple routines with the same name but with different parameters in the same schema (overloading). Thus, for the unique identification of the routine it is necessary to present also its parameters in addition to the schema name and routine name. |
| Type | Problem detection Each row in the result could represent a flaw in the design |
| Reliability | Medium Medium number of false-positive results |
| License | MIT (opens in new tab) |
| Fixing Suggestion | For instance, instead of writing INSERT INTO Person VALUES (1, 'John', 'Smith'); write INSERT INTO Person (person_id, given_name, surname) VALUES (1, 'John', 'Smith'); |
