SQLRef - Website Created By Programmer To Programmers
Sep 14, 2006
Dear All Software Developers,
I am a hardcore programmer who treat programming as a hobby. Recently,
I have just created a website (http://www.sqlref.com) to share my
knowledge and programming experience and to record down any new tricks
that I learned. This website started with SQL info. becaue I think SQL
is the most basic but must know thing for all software developers.
Eventually, I will make this website covers other topics such as .NET,
SQL Server, Oracle, DB2 and so on. I will update it everyday.
I think all developers should be able to access the SQL reference /
Guide at any time, any place. Thus, I created this website for anybody
who need reference on SQL. While you are doing programming and stuck
with the SQL syntax, just open you web browser and type
http://www.sqlref.com
to look for you answer. I guess sqlref.com is easy enought to remember.
No registration is required because I am not selling or marketing
anything. Just a website for programmers to refer.
I hope the website is useful to you all.
Enjoy!
Warmest Regards,
Allen

hi ,
I am using ASP.NET with SQL Server. I have a function ABC() which creates,open ,and then dispose sqlserver's connection .
I am using ABC() twice in one .aspx page ,my friend who build this function argued that this function will open only one connection in everypage ,no matter how many times we call function ABC() in a single page ,while i denies .
Please tell me ,because our whole company database acces relies on this single ABC() function.
Thanks in Advance

I'm used to programming in PHP and need helping learning how to do SQL stuff in VB (using Visual Studio Pro, if that makes a difference).
For instance, in PHP I might do something like this:
//some code to connect to the database
$result = mysql_query("SELECT * FROM `table_name` WHERE `some_field` = true") OR die("ERROR: ".mysql_error());
while ($row = mysql_fetch_assoc($result)) { extract($row); //do what needs to be done with the variables}
How can I do that in Visual Basic?
This is what I have so far and that's only from cutting and pasting from some websites. 1 Using connection As New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True")
2 connection.Open()
3 Dim command As SqlCommand = New SqlCommand("SELECT * FROM GE_Data", connection)
4 'now how do I get to the data???
5
6 connection.Close()
7 End Using

Hello
I've been looking for SSIS examples where you need to import data from a OLE DB datasource and export it to a OLE DB destination source whilst the data in a colum is being transformed with a simple SQL statement.
For example:
SELECT (CONVERT(datetime, Left(Counterdatetime, 23))) datum
FROM CounterData
It seems to me that you have to use the Script Task Component ans start coding in Visual Basic.Net (or whatever)
Am I missing something here or is it normal you have to be a programmer to do simple thins like that?
Many thanks!

In May of this year I graduated from Penn State with a BS in IST (Information Sciences and Technology). Right after graduation I got a database programming job with a company that uses Delphi 6 and MS SQL Server 2000.
I've been working with this company for six months now but I'm still not very good with SQL. I can do basic SQL queries and table joins (as well as use datetime functions and cursors), but I'd say I'm only at an intermediate level (at best).
So... I'm looking to learn more about SQL. I'm guessing a good SQL reference book would help, but I'd really prefer a good book that actually teaches you and guides you along. The only problem is that I don't want a basic/beginner level SQL book since I already know all of the basics.
Can anybody recommend anything for me?
Thanks!

Hi, I'm working in a web project.
In our lab, all the PCs are installed with SQL Server Management Studio, and the codes of the site are left by the previous batch of programmers.
Here is briefly how our web works, the web will call the sql server providing a username (userA) and password (aaaaaa) to log into the database, then the web can connect to the database to do various functions like select, insert, update and delete.
Currently anyone can go to thier SQL Server Management Studio on thier PC to edit various things like names and columns of tables by logging in as userA.
But, we now only want a small number of users to have the ability to change things in the database. What are some ways we can do that?
Something that I've thought of is that only allow userA to log in and do functions like select, insert, update and delete and do not have the ability to edit things like names and columns of tables. Have a userB with password only known to me that can have full control of the database which I have done.

Does anyone have any basic, simple scripts of sp's that I can give mycomputer operators to use to monitor for serious conditions on our sqlservers? We are new in the ms-sql arena, a small shop and we cantreally purchase any tools to monitor these servers, but we need somebasic checks that we can use to make sure a server is performing in areasonable fashion, no blocks, cpu<xx%, memory not pegged, IO working,etc...and we need to be able to do this without bugging ourprogrammers every time we are wondering why things are slowwnig down.We are a split shop between as400s and sql servers, and our operationsstaff has no problem performing this type of duty on the 400s. I thinksince the sql servers are so easy to deploy into production, the ideaof how to monitor these things health got lost in the shuffle andallowing the programmers to do it just serves to destabilize ourenvironment.Please help! Our shop has turned to chaos since we went live withMSSQL centric applications and everytime one programmer "resolves anissue" some other programmers application starts to act up.

trying to get a new database created then running a script to created the tables, relationships, indexes and insert default data. All this I'm making happen during the installation of my Windows application. I'm installing SQL 2012 Express as a prerequisite of my application and then opening a connection to that installed SQL Server using Windows Authentication.
E.g.: Data Source=ComputerNameSQLEXPRESS;Initial Catalog=master;Integrated Security=SSPI; Then I run a query from my code to create the database eg: "CREATE DATABASE [MyDatabaseName]".
From this point I run a script using a Batch file containing "SQLCMD....... Myscriptname.sql". In my script I have my tables being created using "Use [MyDatabaseName] Go CREATE TABLE [dbo].[MyTableName] .....". So question is, should I have [dbo]. as part of my Create Table T-SQL commands? Can I remove "[dbo]."? Who would be the owner of the database? If I can remove the [dbo]., should I also remove dbo. from any query string from within my code?

Hi everyone. This is my
first post here. I did a quick search and didn't find what I as
looking for, so I'm hoping you all can help me.
I'm working on a project that will allow my company to upload images to
a database and have the website pull the images from the DB. We
are planning to incorporate some type of cacheing, however I'm
skeptical as to if it is really necessary. I imagine that I'm
certianly not the first to do this and I'm wondering if someone can let
me know if I truly should expect a performance hit, or if I shouldn't
really worry about it b/c this is a very common mantra.
Thanks all. I've been pretty vague and haven't explained all of
the details. I can write more, but I'm just looking for
generalizations right now.
Thanks,
HD

I am new to .NET and the Visual Web Developer Express and what not...I have created a website on my machine which works wonderfully...however, and I'm sure this is somewhere but I can't find it, I cannot get it to work on my host server...the Default page comes up, but when I try to sign in it says:
"An attempt to attach an auto-named database for file c:hostingwebhost4lifememberharrison0801App_Dataaspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
The host support tells me to change the db name from aspnetdb to something else...I do this and when I run the site again or try to log in, I get the exact same error message...then they go on to tell me that I have to remove the LocalSqlServer in the web.config file which now looks like this:
<connectionStrings> <remove name="LocalSqlServer"/> <add name="LocalSqlServer" connectionString="Data Source=.SQLEXPRESS;Integrated Security=True;AttachDbFilename=|DataDirectory|aspnetdb.mdf;User instance=true;" providerName="System.Data.SqlClient" />
<add name="Example" connectionString="Data Source=.SQLEXPRESS;Integrated Security=True;AttachDbFilename=|DataDirectory|example.mdf;User instance=true;Initial Catalog=example;" providerName="System.Data.SqlClient" />
</connectionStrings>
Of course this isn't working either...otherwise I would off playing on my server, and not posting here. Also, when I set up all the roles, users, and what not on my machine...does this carry over to the host machine?
Desperately needing massive help here....
Not a DBA and no expert in .NET
Thank you very much in advance,

Hi,
It's been a long time since I last experimented with SQL Server (2001) so I am not sure of new product features or developer techniques.
A client of mine is wanting to deploy an E-Commerce website and one if the core requirement is that the site must integrate with his internal MS SQL Database i.e. Orders placed online must be seamlessly entered into his internal Sales database. Ideally this would not require any re-keying or daily batch imports.
Many web hosts offer SQL hosting so how (if it is possible) could I link the hosted database to the internal database?
Any help/tips would be appreciated.
Thanks in advance
Scott.

Hi,
I have a web page where my users are selecting a bunch of filters to generate a report. The page then pulls the initial data from the database, applies some adjustments to the records, and then puts the data in a temporary table for that user. I want to create a report template (or a report saved on the report server) for this report. I want to use the same report for each user but be able to change the datasource for the report on the fly for the current user's temp table in my webpage before displaying the report. Is this possible?
~ Thanks

I wanted to make a login for custom content on my asp website. I installed 2005 sql, gave it a named instance(sql34). I set the connections to local and remote for tcp only in the "surface area config", and made the tcp enabled in "sql manager". All of the sql services are started. So i open up the "server management studio" and it prompts me for a connection. I sellect "database engine" because thats what i installed. I typed the server's name in the "server name" and select sql server authentication for the "authentication", and use my username and password for the login.
Then I get a message cannot connect:
the default settings sql server does not allow remote connections(provider:named pipes provider,error:40-could not open a connections to sql server)(microsoft sql server, error:2)
What is the deal with this?
Another problem was i saw the sql express does not integrate with the real sql 2005. So how do i make mywebsite's web.config(express edition) to integrate for my real sql 2005 server?

Hi,
Im currently running a website in conjuction with MSSQL Express. However at the moment the website/database seems to 'sleep' when no-one is using it, then there are huge dealays accessing the data while the database/website kicks in again. I tried to google this but truthfully i don't know what i am looking for. Does anyone have any ideas? Or whether this problem is Database or website driven? I thought there might be a control in the web.config but i haven't found a solution as yet!
