For CLR functions, all data types, including CLR user-defined types, are allowed except text , ntext , image , user-defined table types and timestamp data types. If a default value is defined, the function can be executed without specifying a value for that parameter.
Default parameter values can be specified for CLR functions except for the varchar max and varbinary max data types. When a parameter of the function has a default value, the keyword DEFAULT must be specified when the function is called to retrieve the default value. This behavior is different from using parameters with default values in stored procedures in which omitting the parameter also implies the default value.
For CLR functions, all data types, including CLR user-defined types, are allowed except the text , ntext , image , and timestamp data types. Inline functions do not have associated return variables.
Often the value contains an embedded period or dot. In such cases the Transact-SQL syntax requires that the value be bounded with a pair of straight brackets [], or with a pair of double quotation marks "". In a typical example, for MyFood. You can create, modify, and drop database objects that reference common language runtime modules; however, you cannot execute these references in SQL Server until you enable the clr enabled option.
This option is not available in a contained database. The table declaration includes column definitions and column or table constraints. The table is always put in the primary filegroup. Defines the table data types for a CLR function. The table declaration includes only column names and data types. This argument is required for natively compiled, scalar user-defined functions. For more information, see Atomic Blocks.
The output of the obfuscation is not directly visible in any catalog views. Users that have no access to system tables or database files cannot retrieve the obfuscated text. However, the text will be available to privileged users that can either access system tables over the DAC port or directly access database files.
Also, users that can attach a debugger to the server process can retrieve the original procedure from memory at runtime. For more information about accessing system metadata, see Metadata Visibility Configuration. Using this option prevents the function from being published as part of SQL Server replication.
This option cannot be specified for CLR functions. The function definition itself must first be modified or dropped to remove dependencies on the object that is to be modified. The binding of the function to the objects it references is removed only when ne of the following actions occurs:.

Determines whether the value of an expression is equal to any of several values in a specified list.
If expr is found in the list of values, the In operator returns True ; otherwise, it returns False. Learn about the categories of built-in functions you can use with SQL databases. You can use the built-in functions or create your own user-defined functions. Aggregate functions perform a calculation on a set of values and return a single value. Use the OVER clause to calculate the aggregation on a specific range of value. All aggregate functions are deterministic, which means they always return the same value when they run on the same input values.
For more information, see Deterministic and Nondeterministic Functions. Analytic functions compute an aggregate value based on a group of rows. However, unlike aggregate functions, analytic functions can return multiple rows for each group. You can use analytic functions to compute moving averages, running totals, percentages, or top-N results within a group.
Ranking functions return a ranking value for each row in a partition. Depending on the function that is used, some rows might receive the same value as other rows. Ranking functions are nondeterministic. FormatNumber Function. FormatPercent Function. FreeFile Function. FV Function. GetAllSettings Function. GetAttr Function. GetObject Function.
