TITLE   :BUG: Query Designer Generates Invalid SQL Statement
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:6.0
OPER/SYS:WINDOWS
KEYWORDS:

======================================================================
---------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual Basic Enterprise Edition for Windows, version 6.0
---------------------------------------------------------------------

SYMPTOMS
========

Under certain conditions, the Query Designer may generate invalid SQL
statement if database is MDB file. When the statement is executed, VB
generates the error:

   Syntax error in FROM clause

RESOLUTION
==========

Manually remove the braces "{}" and "oj" from the "From" statement.

Code Example
------------

Change the following statement

   SELECT Products.ProductName, `Order Details`.Quantity
   FROM { oj `Order Details` LEFT OUTER JOIN
   Products ON `Order Details`.ProductID = Products.ProductID }

To the following:

   SELECT Products.ProductName, `Order Details`.Quantity
   FROM `Order Details` LEFT OUTER JOIN
   Products ON `Order Details`.ProductID = Products.ProductID

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. We are researching this bug and will post
new information here in the Microsoft Knowledge Base as it becomes
available.

MORE INFORMATION
================

Steps to Reproduce Behavior
---------------------------

1. Open Visual Basic and create a new Standard EXE project.

2. On the Project menu, click Add a Data Environment.

3. Right click the connection, select Properties, and select OLEDB Provider
   for Jet 3.51.

4. Click the Connection tab and select the NWind.mdb by using the
   ellipsis button for item 1.

5. Right-click the connection and select "Add a Command."

6. Right-click Command1; select "SQL" as data source. Click SQL Build
   to launch the Query Designer.

7. Drag-drop Table "Order Details" and "Products" onto the diagram pane;
   there is a relationship between these two tables.

8. Check the column "ProductName" in Products and column "Quantity" in
   "Order Details."

9. Right-click the relationship line and select "select all rows
   from 'Order Details'."

RESULT: The SQL sentence in the SQL pane is:

   SELECT Products.ProductName, 'Order Details'.Quantity
   FROM { oj 'Order Details' LEFT OUTER JOIN
   Products ON 'Order Details'.ProductID = Products.ProductID }

This is an invalid SQL statement; when running it, Visual Basic generates
"Syntax error in FROM clause" when it attempts to save the query.
