PostgreSQL Query Catalog

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.

641 Perhaps is not snake_case - Boolean-indicating prefix without underscore Find names of types, domains, columns, and parameters that perhaps do not use the snake_case naming style because the name starts with "is", "has", or "on" that is not followed by an underscore. Prefer snake_case over PascalCase and camelCase in names. Problem detection INFORMATION_SCHEMA+system catalog base tables 2024-12-21 15:44 MIT License View
642 Perhaps is not snake_case - id, code, key, or nr is not followed by an underscore Find names that perhaps do not use the snake_case naming style because the name starts with the phrase "id", "uuid", "code" , "kood", "key", or "nr" that is not followed by an underscore.

644 Perhaps is not snake_case - long subsections without underscores Find names that perhaps do not use the snake_case naming style because the name contains a long subsection (at least 20 characters) without underscores.

645 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.

646 Perhaps primary key columns could be renamed Find the names of simple primary key columns that name does not follow the pattern _id or _code but it is quite similar. Problem detection system catalog base tables only 2022-12-01 14:34 MIT License View
647 Perhaps searching based on a name instead of a code Find derived tables with a search condition that is possible based on a name instead of a code. Problem detection INFORMATION_SCHEMA+system catalog base tables 2024-12-18 11:52 MIT License View
648 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.

649 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.

650 Perhaps the column type should be UUID Find base table columns that do not have uuid type but the name of the column refers to the possibility that the values in the column are uuid's. Problem detection INFORMATION_SCHEMA only 2022-06-09 15:07 MIT License View
651 Perhaps the name referes to multiple concepts Find database objects that name contains words "and" (English) or "ja" (Estonian). Problem detection INFORMATION_SCHEMA+system catalog base tables 2024-12-21 16:36 MIT License View
652 Perhaps the precision in case of a base table column with NUMERIC/DECIMAL type is too small Make sure that in case of using the type DECIMAL/NUMERIC as the type of a base table column the precision (the permitted number of digits in the number) is not too small. For instance, the biggest value in the type NUMERIC(1,1) is 0.9. Problem detection INFORMATION_SCHEMA only 2021-02-25 17:29 MIT License View
653 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.

654 Perhaps the type of a base table column/domain should be BOOLEAN (based on types and default values) Find base table columns and domains that have a textual type and the default value that represents a truth-value. For instance, the type of a column could be VARCHAR and the column has the default value 'TRUE'. Problem detection INFORMATION_SCHEMA only 2021-02-25 17:30 MIT License View
655 Perhaps the type of a base table column/domain should be INTEGER/SMALLINT/BIGINT (based on sequence generators) Specify for each column/domain a right data type that takes into account expected values in the column/domain. Find base table columns and domains that refer to the nextval function by using the default value mechanism but do not have the type INTEGER, SMALLINT, or BIGINT. This check is performed in case of identity columns: ERROR: identity column type must be smallint, integer, or bigint. Problem detection INFORMATION_SCHEMA only 2021-03-04 11:24 MIT License View
656 Perhaps the type of a base table column/domain should be numeric (based on default values) Specify for each column/domain a right data type that takes into account expected values in the column/domain. Find base table columns and domains that have a textual type but the default value that represents a number (for instance, '100', '2', or '0.22'). Exclude columns about formats.

657 Perhaps the type of a base table column/domain should be SMALLINT (based on classifiers) Find columns that name points to the possibility that values in this are classifier codes. The column has a numeric type but it is not SMALLINT. Usually each classifier type has so few values that type SMALLINT would be appropriate.

658 Perhaps the type of a base table column/domain should be temporal (based on default values) Find base table columns and domains that have a textual type but the default value that represents a temporal value (either a static value or invocation of a function that returns such value). Specify for each column/domain a right data type that takes into account expected values in the column/domain. Problem detection INFORMATION_SCHEMA only 2021-02-25 17:30 MIT License View
659 Perhaps the type of a base table column/domain should be temporal (deadlines) Find base table columns that name refers to the possibility that there are registered deadlines but the column does not have a temporal type. Problem detection INFORMATION_SCHEMA only 2021-03-21 17:00 MIT License View
660 Perhaps the type of a base table column/domain should be VARCHAR (based on column names) Find base table columns that have CHAR type, where character maximum length is bigger than 1 and the name of the column does not refer to the possibility that the column holds some kind of codes or flags or hash values.
