| Goal | 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. |
|---|---|
| Notes | The query takes into account a possibility that the default value can be declared to the column directly or through a domain. The query considers both column names in English and Estonian. |
| 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 | Declare to the column a default value that corresponds to the first state that the entity gets after its data is registered in the system. |
| Data Source | INFORMATION_SCHEMA+system catalog |

Categories
This query is classified under the following categories:
Comfortability of data management
Queries of this category provide information about the means that have been used to make the use or management of database more comfortable and thus, more efficient.
Default value
Queries of this catergory provide information about the use of default values.
Result quality depends on names
Queries of this category use names (for instance, column names) to try to guess the meaning of a database object. Thus, the goodness of names determines the number of false positive and false negative results.
Validity and completeness
Queries of this category provide information about whether database design represents the world (domain) correctly (validity) and whether database design captures all the information about the world (domain) that is correct and relevant (completeness).
