等效SAP Hana查询

Question

我需要针对这些SQL查询的等效SAP Hana查询

SELECT * FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
SELECT * FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS 
SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS

我试过这个

SELECT * FROM SYS.KEY_COLUMN_USAGE
SELECT * FROM SYS.REFERENTIAL_CONSTRAINTS 
SELECT * FROM SYS.TABLE_CONSTRAINTS

SYS.REFERENTIAL_CONSTRAINTS效果很好。但我没有得到SYS.KEY_COLUMN_USAGE和SYS.TABLE_CONSTRAINTS的等效表

Answer 1

您检查了sys.constraints系统视图吗？

SELECT * FROM SYS.CONSTRAINTS
