Goal Find domain CHECK constraints that have a too generic name - for instance, the name contains word "data" ) or the name is an abbreviation of the constraint type name (for instance, "chk" or "chk1").
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 (opens in new tab)
Fixing Suggestion Rename the constraints.
Data Source INFORMATION_SCHEMA only
SQL Query
