| 581 | Perhaps incorrect use of 'NULL' | Find Boolean expressions, queries, routines, and default values that refer to value 'NULL'. Perhaps NULL was intended instead. 'NULL' is a string (a value) but NULL is a special marker for denoting missing value. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-11-04 13:19 | MIT License | |

| 587 | Perhaps last update time trigger is missing | Find base tables that have a column for last update time but the table does not have associated before update row level trigger for changing the last update time. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-12-30 15:22 | MIT License | |

| 589 | Perhaps spaces are unnecessarily restricted | Find base table columns that name refers to the possibility that the column is used to record names or textual descriptions but the column seems to have a simple check constraint that restricts spaces in these. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2023-11-18 13:30 | MIT License | |
| 590 | Perhaps textual code columns lack a CHECK constraint | Find non-foreign key textual columns that name refers to the fact that they contain some kind of code but the column does not have any check constraint or the only constraint restricts empty strings or whitespace characters. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2024-07-01 15:43 | MIT License | |

| 592 | Perhaps the type of a base table column/domain should be BOOLEAN (based on CHECK constraints) | Find base table columns and domains that have a CHECK constraint that limits possible values in a manner that seems to indicate that the permitted values represent truth values, i.e., permitted values are 0/1 or true/false. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2021-02-25 17:29 | MIT License | |
| 593 | Perhaps the type of a base table column should be BOOLEAN (based on column names) | Find base table columns that based on the name seem to hold truth values.

| 595 | Perhaps the type of a parameter should be BOOLEAN (based on parameter names) | Find routine parameters that based on the name seem to hold truth values.

| 596 | Perhaps too many different prefixes in the names of database objects that have the same type | One should be consistent in naming, including in the use of prefixes. If you use prefix in the name of a database object, then it should refer to the type of the database object. Do not use different prefixes in the names of database objects that have the same type. Find types of database objects in case of which there are different prefixes in different names. | Problem detection | INFORMATION_SCHEMA+system catalog base tables | 2024-12-21 16:20 | MIT License | |
