Goal Find columns of base and foreign tables that based on the column names are used to register durations but the type of the column is time. "It is possible to use a TIME data type if the duration is less than 24 hours, but this is not what the type is intended for, and can be the cause of confusion for the next person who has to maintain your code."
Type Problem detection (Each row in the result could represent a flaw in the design)
Reliability High (Few or no false-positive results)
License MIT License
Fixing Suggestion Detetrmine the unit of the duration and use an integer type instead.
Data Source INFORMATION_SCHEMA only
SQL Query
SELECT table_type, table_schema, table_name, column_name,  data_type, character_maximum_length
FROM INFORMATION_SCHEMA.columns INNER JOIN INFORMATION_SCHEMA.tables USING (table_schema, table_name)
WHERE data_type~*'time'
AND column_name~*'(kestus|kestvus|duration)'
AND table_type IN( 'BASE TABLE','FOREIGN') 
AND table_schema NOT IN (SELECT schema_name
FROM INFORMATION_SCHEMA.schemata
WHERE schema_name<>'public' AND
schema_owner='postgres' AND schema_name IS NOT NULL)
ORDER BY table_type, table_schema, table_name, ordinal_position;

Collections

This query belongs to the following collections:

NameDescription
Find problems automaticallyQueries, that results point to problems in the database. Each query in the collection produces an initial assessment. However, a human reviewer has the final say as to whether there is a problem or not .
Find problems by overviewQueries that results point to different aspects of database that might have problems. A human reviewer has to decide based on the results as to whether there are problems or not .
Categories

This query is classified under the following categories:

NameDescription
Result quality depends on namesQueries 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.
Structure of base tablesQueries of this category provide information about the structuring of base tables at the database conceptual level
