Sequences Node

About Sequences

A sequence is an object that generates a serial list of unique numbers for numeric columns of a database's tables. Once a user generates a sequence value, that user can continue to access that value regardless of whether the sequence is incremented by another user. You can use sequences to automatically generate primary key values. You can configure sequences to start and stop within a range of values.

How the Sequences Node Works

The Sequences node contains one or more child Sequence nodes. To perform actions on the Sequences node: right-click the node and from the menu, choose the appropriate command. To view the node's properties, select the node and/or click Properties in the node's menu.

If this collection node is filtered, the icon changes to include a funnel symbol. For more information about filtering, see Filtering Collection Nodes.

Menu Options

Menu Option	Description
New Sequence	Creates a new sequence using the Sequence Designer.
Query Window	Opens the Query Window so that you can execute SQL and PL/SQL queries from Visual Studio.
Generate Create Script	Writes the sequence definitions to a `.sql` file. If the object associated with the sequences node is deleted from the database backend, this menu option does the following: Displays a message indicating that this object no longer exists in Oracle Database, and the script will not be generated.
Generate Create Script to Project	Generates the sequence definitions to a .`sql` file and adds the `.sql` file to an open Oracle Database Project. If multiple objects in Server Explorer are selected, a master SQL script is created in the Oracle Database Project Scripts folder. This master script contains calls to individual child SQL scripts (one for each schema object) generated into the various schema object folders and this master script is ordered with dependencies taken into consideration. If there are multiple open Oracle Database projects, Visual Studio prompts you to select the project to add the script to. This operation can also be performed by dragging and dropping the Server Explorer node(s) directly onto a database project folder. See Managing Oracle Script Files for more information. Note: Oracle Database Project Version 2 projects are not supported. To add scripts to this project type, use Import Schema or Add Existing Item menu items on an Oracle Database Project Version 2 project folder, or use the Schema Compare tool.
Filters	Opens the Filters Tab to control which child nodes appear under the collection.
Privileges	Opens the Grant/Revoke Privileges dialog box.
Refresh	Updates the Sequences node tree, including its associated sequence nodes.
Properties	Displays the Properties window.
