I maintain a product that is installed at multiple locations which as been haphazardly upgraded. Unique constraints were added to a number of tables, but I have no idea what the names are at any particular instance. What I do know is the table/columnname pair that has the unique constraints and I would like to write a script to delete any unique constraint on these column/table combinations. This is MSSQL 2000 and later. Something that works on 2000/2005/2008 would be best!

This time my setup looks like this: one table with galleries names (gallery_id, gallery_name) and another table with galleries photos (photo_id, photo_gallery_id, photo_name).
What I need is to get all the galleries with one random picture for each gallery.
Is it possible to do this with a single query?
Say I have a 'user_log' table with the following field:
id
user_id
status_text
timestamp
How do I write a query that selects only the last update for all the users in that table?
Appreciate your help :)
Actually what I want - simple DB with simple User Interface. Like MS Access, but for web and it can be without Dragn n Drop, but described with markup language.
For example if I want to create list report, then i need to write something like:
<table query="SELECT * from mytable"></table>
It needed for simple data applications. In that kind application no programming logic required. Just working with DB. Changing DB data and showing it.
I have four tables
TableA:
id1
id2
id3
value
TableB:
id1
desc
TableC:
id2
desc
TableD:
id3
desc
What I need to do is to check if all combinations of id1 id2 id3 from table B C and D exist in the TableA. In other words, table A should contain all possible combinations of id1 id2 and id3 which are stored in the other three tables.
Hi guys:
Suppose we got a original query as follows:
SELECT A, B, C FROM tblA
Now, I need to additional artificial rows like
SELECT 'Kyala', B, C FROM tblA when, for example, C = 100 to be inserted into the resultset.
How could I achieve it using a single SQL instead of relying on table variable or temp table?
hi,
Am working with sybase.In that i have a table A of some 2 million records containing some columns which i want to move out and make it as a separate table B. I have some questions in this process...
1. I have decided to use vertical partitioning.Is that ok?
2.Or what other technique can i go about using in this process?
Please provide your valuable inputs in this.
Thanks.
Say that I have a table with one column named CustomerId.
The example of the instance of this table is :
CustomerId
14
12
11
204
14
204
I want to write a query that counts the number of occurences of customer IDs.
At the end, I would like to have a result like this :
CustomerId NumberOfOccurences
14 2
12 1
11 1
204 2
14 1
I cannot think of a way to do this.
Assume a Cassandra datastore with 20 rows, with row keys named "r1" .. "r20".
Questions:
How do I fetch the row keys of the first ten rows (r1 to r10)?
How do I fetch the row keys of the next ten rows (r11 to r20)?
I'm looking for the Cassandra analogy to:
SELECT row_key FROM table LIMIT 0, 10;
SELECT row_key FROM table LIMIT 10, 10;

How to add a custom value using LOAD DATA LOCAL INFILE?
The column time_added is the 7th column and the file has only 2 values for the first and the second column. For the 7th column, time_added I want to use the unix timestamp when loading from file.
This code isn't working:
$result = mysql_query("LOAD DATA LOCAL INFILE '{$myFile}' INTO TABLE {$table} FIELDS TERMINATED BY ':' LINES TERMINATED BY '\n' SET `time_added`=unix_timestamp()");
CREATE OR REPLACE PROCEDURE p_createLocaltable
IS
table_already_exist EXCEPTION;
PRAGMA EXCEPTION_INIT (table_already_exist, -00955);
BEGIN
create table local_table as
select * from supplied_table
where rownum < 1;
EXCEPTION
when table_already_exist then
DBMS_OUTPUT.put_line('Table already exists , does not need to recreate it');
END;
can anyone see any problem of the above code?

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?
Hi
I have a table with the following structure:
id int(11),
name varchar(250)
I have lots of records in the table but when I am trying to find a particluar record which has the following value on the name field:
Lorem ipsum d\'olor sit amet
The query is simply returning a blank recordset. I am not being able to figure out this weird behaviour, when my query is as simple as follows:
SELECT * FROM slot_games WHERE name='Lorem ipsum d\'olor sit amet'
Would appreciate your help please! Thanks in advance.
i have a very simple report that is generated from just one table. one of the columns in the table is a date.
i need to be able to allow the user of the report to enter a range of dates and display data only between those dates.
how do i do this?
Hi,
I'm trying to a create an update statement along the following lines:
TABLE car: id | owner_id | type | status
An owner can have multiple cars.
UPDATE car c
SET c.type = 1
WHERE c.owner_id IN ($ids)
AND c.status = [1 IF IT EXISTS, ELSE 0]
$ids is reasonably small (under 50 values).
It seems simple but I can't seem to get my head around it because I can't use a SELECT subquery with an UPDATE to the same table.
Anyone?
Thanks
I'm looking for an example of a good update trigger to update the ModifyDate field of a table.
It would be nice to handle the case where an update command updated more than one record in the table.
Is there a good template or tutorial for this?
Thanks
