Filter Queries

Found 997 queries.

  • All the queries about database objects contain a subcondition to exclude from the result information about the system catalog.
  • Although the statements use SQL constructs (common table expressions; NOT in subqueries) that could cause performance problems in case of large datasets it shouldn't be a problem in case of relatively small amount of data, which is in the system catalog of a database.
  • Statistics about the catalog content and project home in GitHub that has additional information.

441 Insufficient number of user-defined non-trigger routines There must be at least n (four in this case) user-defined non-trigger routines in the database. Problem detection INFORMATION_SCHEMA+system catalog base tables 2021-02-25 17:30 MIT License View
442 Insufficient number of user-defined triggers+rules There must be user-defined triggers and/or rules for at least n (three in this case) tasks in the database. It also means that one should create at least three triggers and/or rules in the database. Problem detection INFORMATION_SCHEMA+system catalog base tables 2024-01-04 11:47 MIT License View

447 Invalid character class PostgreSQL regular expressions do not have character classes word and letter. Problem detection INFORMATION_SCHEMA+system catalog base tables 2021-11-04 12:50 MIT License View
448 Invalid use of the case insensitive search modifier in regular expressions Find regular expression patterns that use (?i) modifier in any other place than at the beginning of the pattern or (?-i) in any place of the pattern. Such use of the modifiers is not supported by PostgreSQL. Problem detection INFORMATION_SCHEMA+system catalog base tables 2021-11-04 16:06 MIT License View
449 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 View
450 Invocation of PL/pgSQL functions from the subqueries of derived tables Find derived tables that subqueries invoke a PL/pgSQL function. Avoid context switch that is caused by the invocation of PL/pgSQL functions from the subqueries of derived tables.

451 IS DISTINCT FROM should be used instead of <> in WHEN clauses Use a right predicate in trigger condition in order to ensure that the trigger executes always when it has to but not more often. IS DISTINCT FROM treats NULL as if it was a known value, rather than unknown. It would be relevant if a column that is referenced in the action condition is optional, i.e., permits NULLs.

452 Is does not return a boolean Find user-defined SQL and PL/pgSQL non-trigger routines that do not return a truth value (for instance, returns an integer or does not return a value at all) although the name suggest that it should return a truth value (TRUE or FALSE).

453 IS NOT DISTINCT FROM in derived tables Avoid using IS NOT DISTINCT FROM because it makes the query planner to avoid using an index. Problem detection INFORMATION_SCHEMA+system catalog base tables 2024-09-28 13:08 MIT License View

455 IS NULL check is probably not needed Find CHECK constraints that refer only to mandatory columns but the Boolean expression has IS NULL condition. Problem detection INFORMATION_SCHEMA only 2022-06-09 13:57 MIT License View
456 JSON type instead of JSONB type "In general, most applications should prefer to store JSON data as jsonb, unless there are quite specialized needs, such as legacy assumptions about ordering of object keys."

458 Length and char_lenfgth functions are used within the same expression Find expressions that refer to both length and char_length functions. Make sure that the expression is correct. Problem detection INFORMATION_SCHEMA+system catalog base tables 2023-11-09 13:44 MIT License View
459 Lifecycle not initiated Find non-primary key and non-unique base table foreign key columns that name refers to the possibility that these are used to register references to a state classifier. The column must belong to a foreign key and does not have a default value. Problem detection INFORMATION_SCHEMA+system catalog base tables 2023-11-26 15:40 MIT License View
