Greetings,
I like to write my inner joins as below,
but someone at work tells me its not as 'performant'
as using the 'inner join' statement.
Is this true ?
Is there a better way to write it ?
thanks

Trying even the most basic queries - select queries joining (inner
join) two tables - and the results are not updatable, and I can't tell
why they aren't. All permissions are on, recordset is dynaset, unique
values is no, etc.. etc..
Here's the SQL if it helps..:
SELECT tbl.ID
FROM tbl INNER JOIN Master ON tbl.IDNumber = Master.IDNumber;

the following query works fine:
select link.idx, link.x_table, link.x_id_a, link.x_id_z, a.strandid,
b.strandid

where link_detail.x_table = 'enclosure' and link_detail.x_id = 3 and
link.idx = link_detail.linkidx
and A.strandid = link.x_id_a and B.strandid = link.x_id_z
would someone please convert this to a more efficient query using inner

Happy New Year everyone! I'm new to both T-SQL and this forum. I'm currently doing an internship and my first task was to create a small program which will send an email detailing the sales of the previous day versus monthly targets and sales. Most of the parts were figured out and eveything was done in Visual Studio. The gist of the code was written in one large chunk of SQL code, as below:

Hi,
I have a stored procedure that uses JOINs to return columns from multiple
tables. I also have another stored proc that that takes a series of params
and updates multiple tables. I used the framework to auto-generate a table
adapter specifying both stored procs as Get/Fill and Update. The problem is
that columns from the JOINed table seem to marked as 'read-only' so trying
to update a row results in an exception. BTW, by default a...

Hello,
I am used to SQL but I am starting to use LINQ.
How can I create Left, Right and Inner joins in LINQ? How to
distinguish the different joins?
Here is a great SQL example:

I'm trying to write a query that selects the top five members of a forum based on how many total points they have. A member's total points are calculated as follows: (3 * # answers posted) + (10 * # questions posted) + (15 * # members recruited). The relevant parts of the tables are listed below:

I created a query in the Access Query Builder that I modified to use with VBA Code so I could reuse it for any record I choose. The one that I created with the Access Query builder works beautifully with the hardcoded criteria. The VBA version with my criteria being set by a variable returns Error 3021.
I am using a DAO Recordset and all I want to do is retrieve the data to place into a report.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
