| 781 | Updatable views with WHERE clause that do not have WITH CHECK OPTION constraint | Find updatable views that restrict rows, i.e., have WHERE clause, but do not have WITH CHECK OPTION constraint. WITH CHECK OPTION constraint prevents updates through the view that violate the predicate of the view. Such updates must be prevented. | Problem detection | INFORMATION_SCHEMA only | 2024-01-14 17:11 | MIT License | |
| 782 | UPDATE triggers where updated columns have not been specified (the trigger could executed too often) | Find UPDATE triggers where updated columns are not specified. These triggers could be executed too often because unneeded executions are not prevented. | Problem detection | INFORMATION_SCHEMA only | 2024-12-23 09:53 | MIT License | |
| 783 | UPDATE triggers where WHEN clause has not been specified (the trigger could executed too often) | Find UPDATE triggers where WHEN clause is not specified. These triggers could be executed too often because unneeded executions are not prevented. | Problem detection | INFORMATION_SCHEMA only | 2024-12-23 09:54 | MIT License | |
| 784 | Grantable usage privileges | Find usage privileges that the carrier of the privilege can in turn grant to others, i.e., the privileges have been given WITH GRANT OPTION. The number of privileges that can be passed on should be as small as possible. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2024-01-07 13:43 | MIT License | |
| 785 | Unused composite types (for table columns, typed tables, input and output parameters) | Find user-defined composite types that are not used in case of any table, column, and routine (input or otput) parameter (as their type). Do not keep in your database elements that are not needed by anybody. These should be put in use or dropped, otherwise these are dead code. | Problem detection | system catalog base tables only | 2021-02-25 17:30 | MIT License | |
| 786 | User-defined non-trigger routines without parameters | Find user-defined non-trigger routines with no parameters. | General | INFORMATION_SCHEMA+system catalog base tables | 2021-11-03 20:05 | MIT License | |
| 787 | A setter does not update a table | Find user-defined non-trigger SQL and PL/pgSQL routines that name starts with "set" (but not with "setting") but do not contain a UPDATE statement. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2022-11-27 18:35 | MIT License | |
| 788 | The name of the routine does not match with the action of the routine | Find user-defined non-trigger SQL and PL/pgSQL routines where the beginning of the name of the routine indicates a certain action inside the routine (INSERT, UPDATE, or DELETE) but there is no such statement in the routine body. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2022-11-19 14:37 | MIT License | |
| 789 | Coalesce/Concat need at least two arguments | Find user-defined routines and derived tables (views/materialized views) that have a subquery that contain an invocation of Coalesce or Concat function with just one argument. You should use the Coalesce and Concat functions correctly by invoking these with at least two arguments. If one invokes these functions with one argument, then the functions will return the input value. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-12-08 11:49 | MIT License | |
| 790 | Perhaps Count(*) is wrongly used | Find user-defined routines and derived tables (views/materialized views) that have a subquery that invokes Count aggregate function like this - Count(*), uses outer join, and grouping. In case of grouping you do not want to get an answer that an empty group contains one member. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-10-25 16:40 | MIT License | |
| 791 | Perahaps Coalesce invocation is missing or Concat should be used | Find user-defined routines and derived tables (views/materialized views) that have a subquery that invokes || operator but does not use Coalesce function to ensure that the arguments are not NULL. In PostgreSQL expression value || NULL returns NULL. In order to get value as the result, one has to replace NULL with a value (empty string) by using, for instance, Coalesce function (an alternative is to use a CASE expression). Instead of || + Coalesce, one could use Concat, Concat_ws, or Format functions for the concatenation. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-12-08 11:51 | MIT License | |
| 792 | A routine is invoked only once | Find user-defined routines that are invoked by exactly one user-defined routine. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2024-12-22 14:53 | MIT License | |
| 793 | The reference to a database operation is missing from a comment | Find user-defined routines that comment does not contain a reference to a database operation that the routine implements. In case of routines that have been created based on the contracts of database operations, one should refer to the short identifier of the operation in the comment of the routine. The operation identifier must be in this case in the form OP, but other forms could be used as well. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-11-04 11:39 | MIT License | |
| 794 | Invocation of a system-defined routine without providing any arguments | Find user-defined routines that contain an invocation of a system-defined function without providing any argument. The query considers all aggregate functions as well as some popular scalar functions. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-12-22 13:00 | MIT License | |
| 795 | Unnamed columns in routines | Find user-defined routines that contain a SQL statement that does not give the name to a column in a SQL statement. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-12-22 00:04 | MIT License | |
| 796 | User-defined routines that read data | Find user-defined routines that contain SELECT … FROM or PERFORM … FROM operations. PostgreSQL uses multiversion concurrency control (MVCC). Therefore, SELECTs do not block modifications and vice versa. One has to take steps to achieve correct behaviour of data access code. In addition, one should not ask data with multiple queries if it is possible to achieve the result with only one query. | General | INFORMATION_SCHEMA+system catalog base tables | 2023-12-21 15:00 | MIT License | |
| 797 | Updating or deleting data in a routine without restricting rows | Find user-defined routines that contain UPDATE or DELETE statement but do not contain any WHERE clause, meaning that at least one UPDATE or DELETE operation influences all the rows of a table. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-29 13:21 | MIT License | |
| 798 | Consistency of comments of routines | Find user-defined routines that have a comment registered by the COMMENT statement and a comment within the routine body. Make sure that there are no inconsistencies between the comments. | General | INFORMATION_SCHEMA+system catalog base tables | 2024-12-19 10:53 | MIT License | |
| 799 | Explicit locking is missing (2) | Find user-defined routines that have a subquery in a DELETE or UPDATE statement without the FOR UPDATE clause. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-12-06 12:15 | MIT License | |
| 800 | Are there enough routines that implement database operations? | Find user-defined routines that implement database operations (comment refers to an operation) but show these only if there are at least eight such routines. Contracts of database operations are specified in the system analysis documentation. The contracts apply the idea of design by contract in the field of databases. | General | INFORMATION_SCHEMA+system catalog base tables | 2021-11-03 20:07 | MIT License | |
