Contains one row for all schema-scoped system objects that are included with Microsoft SQL Server. All system objects are contained in the schemas named sys or INFORMATION_SCHEMA.
| Column name | Data type | Description |
|---|---|---|
| name | sysname | Object name. |
| object_id | int | Object identification number. Is unique within a database. |
| principal_id | int | ID of the individual owner if different from the schema owner. By default, schema-contained objects are owned by the schema owner. However, another owner can be specified by using the ALTER AUTHORIZATION statement to change ownership. Is NULL if there is no other individual owner. Is NULL if the object type is one of the following: C = CHECK constraint D = DEFAULT (constraint or stand-alone) F = FOREIGN KEY constraint PK = PRIMARY KEY constraint R = Rule (old-style, stand-alone) TA = Assembly (CLR) trigger TR = SQL trigger UQ = UNIQUE constraint |
| schema_id | int | ID of the schema that the object is contained in. For all schema-scoped system objects that included with SQL Server, this value will always be in (schema_id('sys'), schema_id('INFORMATION_SCHEMA')) |
| parent_object_id | int | ID of the object to which this object belongs. 0 = Not a child object. |
| type | char(2) | Object type: AF = Aggregate function (CLR) C = CHECK constraint D = DEFAULT (constraint or stand-alone) F = FOREIGN KEY constraint FN = SQL scalar function FS = Assembly (CLR) scalar-function FT = Assembly (CLR) table-valued function IF = SQL inline table-valued function IT = Internal table P = SQL Stored Procedure PC = Assembly (CLR) stored-procedure PG = Plan guide PK = PRIMARY KEY constraint R = Rule (old-style, stand-alone) RF = Replication-filter-procedure S = System base table SN = Synonym SQ = Service queue TA = Assembly (CLR) DML trigger TF = SQL table-valued-function TR = SQL DML trigger TT = Table type U = Table (user-defined) UQ = UNIQUE constraint V = View X = Extended stored procedure |

| create_date | datetime | Date the object was created. |
| modify_date | datetime | Date the object was last modified by using an ALTER statement. If the object is a table or a view, modify_date also changes when a clustered index on the table or view is created or altered. |
| is_ms_shipped | bit | Object is created by an internal Microsoft SQL Server component. |
| is_published | bit | Object is published. |
| is_schema_published | bit | Only the schema of the object is published. |
