"SELECT * into mycustomer from customer WHERE 1=2"
In this query, what is "WHERE 1=2" ?
Thanks in advance.

I am trying to use open query to run a stored procedure in a remote database, and insert it into a table in my local database:
-- this works
exec remotesvr.sys.dbo.golden_table 'some', 'parameters'
While the above works out, I try the following:
insert into my_local_table
exec remotesvr.sys.dbo.golden_table 'some', 'parameters'
I get a SQL error to the effect of 'unable to begin a distributed transaction'.
Is there any way around this?, i.e. can I execute take the results of a remote stored procedure and put its contents in a local table?

How to remove digits from the end of the string using SQL?
For example, the string '2Ga4la2009' must be converted to 2Ga4la. The problem is that we can't trim them because we don't know how many digits are in the end of the string.
Best regards, Galina.
I have a asp:GridView with a HyperLinkField. It's DataNavigateUrlFormatString property is set to View.aspx?id={0}&isTechnical={1}
Select command of appropriate SqlDataSource returns columns of type INT and BIT (from SQL Server 2008).
So displayed string becomes something like View.aspx?id=1&isTechnical=1. But I want to display isTechnical=true|False, i.e. Convert.ToBoolean(row["isTechnical"]).ToString().ToLowerInvariant().
How to implement such conversion in page markup?

I have a MySQL table with a column called "priority". The column can have two values: high or low. I want to select 8 records from the table at random, but I want 6 of them to be high priority, and 2 of them to be low priority. If possibly, I would like to do it in one SQL statement. Is there any way to do two LIMITS in one query based on this kind of criteria?
Say I have these tables:
people(id, name),
cars(person_id, car)
and this query:
SELECT c.car
FROM people as p, cars as c
WHERE c.person_id = p.id
AND p.id = 3
I want the c.car column to take its name from the name field in the people table, like this (invalid SQL, just to illustrate):
SELECT c.car AS(SELECT name FROM people WHERE id = 3)
How do I do that?
Is there a catchall function somewhere that works well for sanitizing user input for sql injection and XSS attacks, while still allowing certain types of html tags?
Not quite sure what I'm missing, but my SQL statement is only returning one row.
SELECT
tl.*,
(tl.topic_total_rating/tl.topic_rates) as topic_rating,
COUNT(pl.post_id) - 1 as reply_count,
MIN(pl.post_time) AS topic_time,
MAX(pl.post_time) AS topic_bump
FROM topic_list tl
JOIN post_list pl
ON tl.topic_id=pl.post_parent
WHERE
tl.topic_board_link = %i
AND topic_hidden != 1
ORDER BY %s
I have two tables (post_list and topic_list), and post_list's post_parent links to a topic_list's topic_id.
Instead of returning all the topics (where their board's topic_board_link is n), it only returns one topic.
