How to: Outline and Add Snippets to Transact-SQL Script

  • Článok

SQL Server Data Tools includes a code library consisting of code snippets that are ready to be inserted in your application. Each snippet performs a complete scripting task such as creating a function, table, trigger, index, view, user-defined data type, etc. You can insert a snippet into your source code with a few mouse clicks. These snippets increase your productivity by reducing the amount of time you spend typing.

When you need to browse for an appropriate snippet, you can use the snippet picker, which gives you categorized lists of snippets to choose from. Once you have added the snippet to your code, there may be parts of it that need customization, such as replacing variable names with more appropriate names, or putting in the actual logic of a stored procedure. You will notice that the inserted snippet code has one or more replacement points highlighted in the code for this purpose. If you rest your mouse pointer over the replacement point, a ToolTip appears that explains how you can change the code.

By default, all text is displayed in the Transact-SQL Editor, but you can choose to hide some code from view. The Transact-SQL Editor allows you to select a region of code and make it collapsible, so that it appears under a plus sign (+).You can then expand or hide the region by clicking the plus sign (+) next to the symbol. Outlined code is not deleted; it is just hidden from view.

Warning

The following procedure uses entities created in previous procedures in the Project-Oriented Offline Database Development sections.

To insert snippets

  1. Right-click the TradeDev project in Solution Explorer and select Add, then Script. In the Add New Item dialog box, click Add.

  2. Right-click the Transact-SQL editor and select Insert Snippet. The code snippet picker appears.

  3. Double-click Table in the code snippet picker, then double-click Create Table.

  4. Notice that replacement points are highlighted in yellow. Hover your mouse over Sample_Table, and an infotip displays a description of the replacement. Double-click Sample_Table and change it to Shipper2.

  5. Use the TAB key to move to the next replacement point, which is column_1. Rename it to Id. Follow the same steps to rename column_2 to name and change its data type to nvarchar(128) and allow NULL.

To outline code

  1. Notice the - sign next to the CREATE TABLE statement. Click the - sign next to a section in the script to hide it.

  2. Right-click the Transact-SQL Editor and select Outlining, then Stop Outlining to remove the outline information without affecting your underlying code in the editor.

  3. To start outlining your code again, right-click the Transact-SQL Editor and select Outlining, then Start Automatic Outlining. You can also select Toggle All Outlining to switch the expand/hide sections.
