I have the following code. I would like username to take the value of the getUserName function however I am fighting with syntax. Can anybody tell me what should be the correct one?
$query = "SELECT user FROM users_entity WHERE username = getUserName()";
I have the below query
Select
case upper(device_model)
when 'IPHONE' then 'iOS - iPhone'
when 'IPAD' then 'iOS - iPad'
when 'IPOD TOUCH' then 'iOS - iPod Touch'
Else 'Android'
End As Device_Model,
count(create_dtime) as Installs_Oct17_Oct30
From Player
Where Create_Dtime >= To_Date('2012-Oct-17','yyyy-mon-dd')
And Create_Dtime <= To_Date('2012-Oct-30','yyyy-mon-dd')
Group By Device_Model
Order By Device_Model
This spits out multiple rows of results that read "Android"....I would like there to be only 4 results rows, one for each case....so it comes out like this:
Device_Model Installs_Oct17_Oct30
Android 987
iOS - iPad 12003
iOS - iPhone 8563
iOS- iPod Touch 3482
This simple query throws the "Ambiguous column name TaskID" error on one db-server only. This is ridiculous. We tested this with the same database structure on different servers and different versions of ms sql (2005/2008), and it's only THIS particular client's server that throws the error. I'm actually frustrated.
SELECT Tasks.TaskID
FROM Tasks
INNER JOIN TaskHelpers ON TaskHelpers.TaskID = Tasks.TaskID
order by TaskID
Yes, I know I can put "Tasks.TaskID" into the order by clause, but for some reasons I can't.
Hi all, i want to ask about development in blackberry. I have background in .Net winform.
If i want to develop an application to show data from Ms.SQL server 2008 database in blackberry. what should i learn and what should i do ? thank you for your advice.
E.g.
Declare @str varchar2(20)
Set @str = 'A Student'
Select Reverse(@str)
Output:
tnedutS A
Expected being:
Student A
The output(using Reverse) is as expected. But my requirement is the one described.

I am using SQL SERVER 2005
Trying to convert this tax-like IRS function http://stackoverflow.com/questions/1817920/calculating-revenue-share-at-different-tiers to SQL. The assumption is the table would be one column (price) and the tiers will be added dynamically.
My first attempt has some case statements that didn't work out well. I have since scrapped it :) Thanks for the help!
Hello,
I've been playing today with stored procedures. I'm stoned that I picked the basic of it up so easily. (I'll also try triggers very soon).
Now, I'd like to know how to save my SPROC under the stored procedure folder (Programmability - Stored Procedure) so that I can access it by name (eventually from my C# application). So far, when I press the save icon, I'm proposed to save the whole query. That's not what I want.
Thanks for helping
Hi,
I have a table of items stored this way :
A1 | B1
A1 | B2
A1 | B3
A2 | B1
A2 | B4
...
And I need to retrieve with a SQLQuery :
A1 | B1, B2, B3
A2 | B1, B4
...
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?
I have table similar to the following:
Year | Product | Value
2006 A 10
2006 B 20
2006 C 30
2007 A 40
2007 B 50
2007 C 60
I would like a query that would return the following comparison
Product | 2006 Value | 2007 Value
A 10 40
B 20 50
C 30 60
What are the options to do so? Can it be done without joins?
I'm working with DB2, but answers in all SQL types would be helpful.
What is a candidate row when talking about Oracle and SQL? Using it in a sentence would be as such:
"The candidate row is fetched from the table specified in the outer query."
I am getting a SqlConnection does not support parallel transactions. exception and this answer mentions its when a connection tries to open two transactions. This is exactly what i am doing. I thought nested transactions were ok (i was using sqlite for the prototype).
How do i check if the connection is already in a transaction? I am using Microsoft SQL Server Database File.
Hi,
I have a server where I installed SQL Server 2008 and after I applied the SP1.
Now, I want also to add the Analysis Services to this instance by using the "Add or remove features...".
My questions are:
Is it possible to add the Analysis Services on a server with SP1 already installed?
How can I apply the SP1 also to the new Analysis Service feature?
THANKS!

Hi

I have two SQL 2005 instances that reside on different networks. I need to backup a database from instance A and restore it to a database in instance B on a weekly basis so that both databases hold the same data. After the restore, logins SIDS on database B are changed and therefore users can't log into database B and connection strings for the web application it supports are broken. Is there a work around for this? Thanks.
Hi,
I want to develop a function in PHP that checks how dangerous a SQL statement is. When i say dangerous i mean, certain symbols, characters or strings that are used to get data from a database that the user shouldnt see.
For example:
SELECT * FROM users WHERE userId = '1'
can be injected in several ways. Although i clean the params, i also want to monitor how safe the query is to run.
Thanks in advance
I have two tables that have relationship with UserName field. Based on UserName column, I want to get ID from CarReserve table. Here is my SQL statement:
SELECT CarReserve.ID
FROM CarReserve
INNER JOIN aspnet_Users ON CarReserve.UserName = aspnet_Users.UserName
WHERE UserName = @UserName
Unfortunately, I am getting this warning:
Ambiguous column name "UserName"
Can anyone here tell me what is wrong with my statement?
I was wondering if there was any recommended max size for MDF and/or LDF Files for an SQL server instance.
For example, if I want to create a 400 GBytes Database, is there a rule to help me decide how many mdf files I should create ? or should I just go ahead and create a single gigantic 400Gbytes mdf file?
If so is this going to somehow affect the database performances ?
I'm trying to learn SQL to store the data rather than reading the file and populating the whole data structure in memory. would it be like reading the data from disk instead of direct memory?
From here
ALTER TABLE ORDERS
ADD FOREIGN KEY (customer_sid) REFERENCES CUSTOMER(SID);
How do i add several keys with SQL Server? is it something like the below? (I cant test ATM and unfortunately i have no way to test queries unless i run it through code)
ALTER TABLE ORDERS
ADD FOREIGN KEY (customer_sid) REFERENCES CUSTOMER(SID),
ADD FOREIGN KEY (customer_sid2) REFERENCES CUSTOMER(SID2);
or is it like
ALTER TABLE ORDERS
ADD FOREIGN KEY (customer_sid, customer_sid2) REFERENCES CUSTOMER(SID, SID2)
