Summary: Visual Studio 2005 DataSet Designer "Add Query..." wizard fails with a syntax error if SELECT query contains a WHERE clause

Initial Comment:
Hi,

I'm using the latest version of the drivers: 8.02.00.02 and PostgreSQL 8.1 on Windows XP Pro.

When adding simple queries to TableAdapters in Visual Studio 2005 using the DataSet Designer, a simple WHERE clause causes the Add Query

wizard to fail with a syntax error, even though the query executes perfectly if you test it during an intermediate Wizard step.

Simple Steps To Reproduce
-------------------------
1. Open an existing DataSet in the DataSet Designer (or create a new one)
2. Add a TableAdapter, with a simple query (in my case "SELECT * FROM agent")
3. Add a Query to the TableAdapter:
Right-click on TableAdapter > Add Query.. > Use SQL statements > SELECT which returns rows
4. Type in a simple SELECT using a single WHERE clause (in my case "SELECT * from agent WHERE (agent_id = ?)")
5. Click Query Builder.. > Execute Query (prompts for Query Parameter and executes perfectly)
6. Click OK > Next > Next (leave "Fill a DataTable" and "Return a DataTable" checked) > Next
At this point, even though the query executed perfectly in the Query Builder, you get an error:
"The wizard detected the following problems when configuring TableAdapter query "FillBy":
Details:
Generated SELECT statement.
ERROR [42601] ERROR: syntax error at or near ")";
Error while executing the query"

I have found a partial workaround:
1. Use the Wizard to create the query (with WHERE clause omitted)
2. Right-click on the new query and select properties
3. Modify the query in the CommandText property window

Logs attached.

Regards,

Patrick

May or may not be useful, but I've just noticed that the
error message also appears in PostgreSQL 8.1's error log:

ERROR: syntax error at or near ")" at character 39
