Query goal: | Find columns of base tables that have default value CURRENT_USER. |
Notes about the query: | The query finds default values that are associated directly with a base table column as well as default values that are specified through a domain. The query does not find default values of domains that are not associated with any table. |
Query type: | Problem detection (Each row in the result could represent a flaw in the design) |
Query reliability: | Medium (Medium number of false-positive results) |
Query license: | MIT License |
Fixing suggestion: | Use instead reference to function SESSION_USER. |
Data source: | INFORMATION_SCHEMA only |
