Some examples of character functions in SQL include: CONCAT This CONCAT function concatenates two or more strings together. For example, we can use CONCAT to combine the city and state columns in our "Weather" table: LENGTH The length function returns the number of characters in a string. For...
As seen in the examples above, it can be a good idea to have no filter in the view definition but rather be able to filter data when selecting from the view. However, it can also be a good idea to hide data from a user that you do not want the user to see. ...
We''ll start by explaining each function individually with examples; and then I will show a scenario where these functions can be used together. RIGHT and LEFT These functions might sound fairly self explanatory, but unless you have a fundamental understanding of how they behave; yo...
but the magic is that you can query data and apply functions in the same statement. Today, we’ve seen basic examples. Later in this series, we’ll use them to solve more complicated problems (with more complicated queries), so stay tuned. ...
Function. We will use real-life practical examples and code snippets with sample output for an explanation of every SQL Time Function. In these examples, different scenarios will be demonstrated in which one needs while writing SELECT queries including the calculations and manipulations of the time....
The following examples creates a multistatement scalar function. The function takes one input value, a ProductID, and returns a single data value, the aggregated quantity of the specified product in inventory. USE AdventureWorks2008R2; GO IF OBJECT_ID (N'dbo.ufnGetInventoryStock', N'FN') IS...
Transact-SQL provides the following ranking functions: Expand table RANK NTILE DENSE_RANK ROW_NUMBER Examples The following shows the four ranking functions used in the same query. For function specific examples, see each ranking function. Copy USE AdventureWorks2008R2; GO SELECT p.FirstName, p...

Examples of function resolution The following are examples of function resolution. (Note that not all required keywords are shown.) This is an example illustrating the SQL path considerations in function resolution. For this example, there are eight ACT functions, in three different schemas, register...
CHANGETABLE(CHANGES …) takes a last synchronization version as an argument. The last synchronization version is obtained using the@last_synchronization_versionvariable, as shown in the examples in this topic. The semantics of the last synchronization version are as follows: ...
