Transact-SQL Syntax Supported by IntelliSense

Article
03/06/2017

This topic describes the Transact-SQL statements and syntax elements that are supported by IntelliSense in SQL Server 2014.

Statements Supported by IntelliSense

In SQL Server 2014, IntelliSense supports only the most commonly used Transact-SQL statements. Some general Database Engine Query Editor conditions might prevent IntelliSense from functioning. For more information, see Troubleshooting IntelliSense (SQL Server Management Studio).

Note

IntelliSense is not available for encrypted database objects, such as encrypted stored procedures or user-defined functions. Parameter help and Quick Info are not available for the parameters of extended stored procedures and CLR Integration user-defined types.

SELECT Statement

The Database Engine Query Editor provides IntelliSense support for the following syntax elements in the SELECT statement:


SELECT	WHERE
FROM	ORDER BY
HAVING	UNION
FOR	GROUP BY
TOP	OPTION (hint)

Additional Transact-SQL Statements That Are Supported

The Database Engine Query Editor also provides IntelliSense support for Transact-SQL statements that are shown in the following table.

Transact-SQL statement	Syntax supported
INSERT	All syntax, except the execute_statement clause.
UPDATE	All syntax.
DELETE	All syntax.
DECLARE @local_variable	All syntax.
SET @local_variable	All syntax.
EXECUTE	Execution of user-defined stored procedures, system stored procedures, user-defined functions, and system functions.
CREATE TABLE	All syntax.
CREATE VIEW	All syntax.
CREATE PROCEDURE	All syntax, with the following exceptions: There is no IntelliSense support for the EXTERNAL NAME clause. In the AS clause, IntelliSense supports only the statements and syntax that are listed in this topic.
ALTER PROCEDURE	All syntax, with the following exceptions: There is no IntelliSense support for the EXTERNAL NAME clause. In the AS clause, IntelliSense supports only the statements and syntax that are listed in this topic.
USE	All syntax.

IntelliSense in Supported Statements

IntelliSense in the Database Engine Query Editor supports the following syntax elements when they are used in one of the supported Transact-SQL statements:

All join types, including APPLY
PIVOT and UNPIVOT
References to the following database objects:
- Databases and schemas
- Tables, views, table-valued functions, and table expressions
- Columns
- Procedures and procedure parameters
- Scalar functions and scalar expressions
- Local variables
- Common table expressions (CTE)
Database objects that are referenced only in CREATE or ALTER statements in the script or batch, but which do not exist in the database because the script or batch has not yet been run. These objects are as follows:
- Tables and procedures that have been specified in a CREATE TABLE or CREATE PROCEDURE statement in the script or batch.
- Changes to tables and procedures that have been specified in an ALTER TABLE or ALTER PROCEDURE statement in the script or batch.
Note

IntelliSense is not available for the columns of a CREATE VIEW statement until the CREATE VIEW statement has been executed.

IntelliSense is not provided for the previously listed elements when they are used in other Transact-SQL statements. For example, there is IntelliSense support for column names that are used in a SELECT statement, but not for columns that are used in the CREATE FUNCTION statement.

Examples

Within a Transact-SQL script or batch, IntelliSense in the Database Engine Query Editor supports only the statements and syntax that are listed in this topic. The following Transact-SQL code examples show what statements and syntax elements IntelliSense supports. For example, in the following batch, IntelliSense is available for the SELECT statement when it is coded by itself, but not when the SELECT is contained in a CREATE FUNCTION statement.

USE AdventureWorks2012;  
GO  
SELECT Name  
FROM Production.Product  
WHERE Name LIKE N'Road-250%' and Color = N'Red';  
GO  
CREATE FUNCTION Production.ufn_Red250 ()  
RETURNS TABLE  
AS  
RETURN   
(  
    SELECT Name  
    FROM AdventureWorks2012.Production.Product  
    WHERE Name LIKE N'Road-250%'  
      AND Color = N'Red'  
);GO

This functionality also applies to the sets of Transact-SQL statements in the AS clause of a CREATE PROCEDURE or ALTER PROCEDURE statement.

Within a Transact-SQL script or batch, IntelliSense supports objects that have been specified in a CREATE or ALTER statement; however, these objects do not exist in the database because the statements have not been executed. For example, you might enter the following code in the Query Editor:

USE MyTestDB;  
GO  
CREATE TABLE MyTable  
    (PrimaryKeyCol   INT PRIMARY KEY,  
    FirstNameCol      NVARCHAR(50),  
   LastNameCol       NVARCHAR(50));  
GO  
SELECT

After you type SELECT, IntelliSense lists PrimaryKeyCol, FirstNameCol, and LastNameCol as possible elements in the select list, even if the script has not been executed and MyTable does not yet exist in MyTestDB.
