Teradata Developer Tools for Visual Studio (32-bit)
This extension only supports the versions of Visual Studio indicated in the "Works with" section found on this page. It does not support Visual Studio Code, Visual Studio for Mac, or Visual Studio 2022. The extension for Visual Studio 2022 can be found here.
If you have any questions or problems installing or using this extension, please contact Teradata support or post a question in the Q&A section. Posting questions or problems in the Review section is not an appropriate way to resolve issues.
The Teradata Developer Tools for Visual Studio contains:
- A Teradata Query tool
- A Teradata Explorer tool
- A Table Edit tool
- A New Table Designer
A list of bug fixes appears near the bottom of this page
In addition we add a Teradata menu to the main menu bar and an optional Teradata toolbar.
The menus and toolbars can be customized using the standard Tools, Customize menu.
All Colors, Fonts, and Teradata Developer Tool specific options can be set through the standard Tools, Options pages.
The Query Editor
This allows you to open custom Editor windows that can be used to compose SQL queries for the Teradata Database
and execute those queries using the .NET Data Provider for Teradata.
These windows provide the following functionality:
- Color coding indicates Keywords, Functions, Strings, Comments, etc.
- Intellisense displays Database, Table, View, Alias, Column and Built-in Function names
- Quick-Info displays prototypes and descriptions for Built-in Functions
- Optional outlining: Collapsible sections that may be mid-line
- Brace Matching for Parens, Quotes, Comment delimiters and Keyword pairs
- Execute individual statements, or sets of statements
- Check the validity of a statement and return meta data describing the result columns
- Highlighting of a logical block of code
- Indentation, Comment/Uncomment, Find, Replace, etc. integrated with the VS menus
- Record and replay keyboard macros
- Support for automatic recovery and redrive for connection errors
We also provide a History tool window that will display a record of the queries that you have previously executed.
This window contains the SQL that was executed along with result meta-data and optional notes.
The Teradata Explorer
This is a Tool window that displays the Teradata Data Sources you have connected to.
It allows you to browse their contents and perform various functions on the data objects.
This window provides the following functionality:
- Display all databases, and optionally users, defined on each Teradata system
- Expand a database to display the Tables, Views, Macros, etc. that it contains.
- Further expand these objects to display their Columns, Parameters, Indexes etc.
- Create a new Teradata table (see below)
- Edit the data within a table (see below)
- Display the Create Text for an object in a new Query window
- Insert Select, Insert or Create statements for a table directly into the current Query, or Code window.
(String formatting/escaping will be added to match the language of the target window.)
- Display detailed properties for an object in the Properties window
- Rename or Drop objects
- Securely change the password used by a Data Source
- The data will be persisted and therefore available when you are offline
The Table Editor
A Table Editor window is created using the Edit Table
context menu in the Teradata Explorer.
These windows provide the following functionality:
- Display the data in a Teradata table
- Add new rows to an existing table
- Modify the data values in existing rows
- Delete existing rows from a table
- Script all, or selected, rows to a Query window or a file
- Paste a 'table' of rows into a table. The source may be a Word Table, Excel data, or any application that provides tab delimited data in the clipboard.
- In all cases the data entered will be validated within the application to ensure it is of the correct data type for the target column.
The Table Designer
A Table Designer window is created using the Add New Table
context menu in the Teradata Explorer.
The designer window contains 3 sections:
The Table, Columns, and Constraints can be further defined using the Properties window.
- A Columns Grid that allows you to enter the base information for each column, and to create constraints based on the selected columns.
- A Constraint Tree that allows you to see the constraints that you have defined, add security constraints, or normalize a derived period.
- An SQL Text window that displays the DDL that has been generated from your input.
The table can then be created using the standard Execute command, or scripted using either of the Script commands.
Enhancements and Fixes in 17.20.0
- The 32-bit extension supported by Visual Studio 2019 and older will convert the History file-based database from the no-longer-supported SQL Server Compact Edition format to the SQLite format.
