The new sequence object introduced in SQL Server 2012 has several advantages over IDENTITY columns. For our work here, we will use system views to collect a list of all identity columns in a given database. A constructed type is specified using one of SQL's data type constructors, ARRAY, REF, and ROW. Each column in a database table is required to have a name and a data type. System views provide us with information about tables, schemas, columns, and other objects in SQL Server. The object-oriented paradigm is illustrated below: Objects and Identity The following figure shows object with state and behavior. SQL Data Types. If you do not have SQL Server 2012 here is the way to get SQL Server 2012 AdventureWorks database. Let us run following queries. Array types are the only examples of constructed types known generically as collection types. Each column, variable and expression has a related data type in SQL. However, certain reference types aren't lightweight enough to work as value types, but nevertheless have value semantics. The 1.x Object Relational Tutorial and Core Tutorial are the legacy tutorials that should be consulted for existing SQLAlchemy codebases. I am using AdventureWorks2012 as a sample database. ... A string object that can have 0 or more values, chosen from a list of possible values. The sys.dm_sql_referenced_entities Dynamic Management Function (DMF) returns every user-defined entity that is referenced by name in the definition of the referencing database object that you specify. You can use these data types while creating your tables. You can choose a data type for a table column based on your requirement. There is a unique object identifier OID to identify the object. The type is either an array type, a reference type or a row type, according to whether it is specified with ARRAY, REF, or ROW, respectively. Find Referecing Objects of a particular object. In general we expect Equals() for reference types to do an identity comparison (to check whether the objects actually are the same in memory). However, some of the of the benefits such as updating of sequence object values may come at greater cost – such as data integrity and unique constraint violations. It also makes data migrations from non-Microsoft database platforms very convenient. For reference types, as discussed above, the situation is trickier. We can use these to generate lists of different types of objects that can then be used for reporting or further research. The state is represented by the values of the object's attributes, and the behavior is defined by the methods acting on the state of the object. I saw this post to identify all the objects that reference a particular synonym and used the base logic in the answer in a recursive CTE to identify all the objects related to a comma-delimited list of the objects within the top level query being executed.. About sys.types; In SQL Server, details regarding a specific table column (e.g., column name, column id, column data type, column constraints) can be retrieved by joining system tables such as sys.tables, sys.columns, and sys.types. Declare @baseObjects Nvarchar(1000) = '[Schema].[Table],[Schema].[View],[Schema].[Function],[Schema].
