Is there a TSQL script that will allow me to see the contents of a constraint. I found a question regarding Oracle but I need a TSQL script.

    sys.default_constraints for default constraints on columns

    sys.check_constraints for check constraints on columns

    sys.key_constraints for key constraints (e.g. primary keys)

    sys.foreign_keys for foreign key relations

    sys.check_constraints for check constraints on columns, not valid for check constraints on tables. Eg: CONSTRAINT CK_NumeroUsadas_NumeroTotal CHECK (NumeroUsadas <= NumeroTotal AND NumeroTotal >= 0),

    Search for text inside a constraint:

    1.) SELECT CONSTRAINT_NAME,CHECK_CLAUSE FROM INFORMATION_SCHEMA.CHECK_CONSTRAINTS WHERE CHECK_CLAUSE like '%NumeroTotal%' or CHECK_CLAUSE LIKE '%NumeroUsadas%'

    2.) SELECT object_definition(OBJECT_ID(CONSTRAINT_NAME)),* FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE CONSTRAINT_TYPE = 'CHECK' AND object_definition(OBJECT_ID(CONSTRAINT_NAME)) like '%NumeroTotal%' or object_definition(OBJECT_ID(CONSTRAINT_NAME)) LIKE '%NumeroUsadas%'
