I'm use to working with MSaccess and coldfusion and am trying to convert to sql. I ran the upsize wizard in access and now see my DB in the SQL Query Analyzer. How do I open / modify / view the DB? I have zero experience with sql so treat me like a 5 year old.
And if anyone has any knowledge of connecting coldfusion with sql that would also help.
Thanks.
can anyone explain what are superkeys & candidate keys with a simple example?
Thanx...
Begging your patience, I'm wondering if someone can help me with a beginner question. I am trying to write a query against our trouble ticket DB. I want to find tickets that have multiple tech assignments associated with a single ticket. How can write a query that says if in the CALLID field you find the same value more than once, return those rows and only those rows?
Thanks very much.
Hi,
I have a query that takes 15minutes to run the first time after sql server start but then for subsequent querys is superfast (less than 10 secs).
Why? What could I do to speed up the first run?

Hi,
This is probably a no-brainer for most of you, but I'm really really new to sql.
I'm using ms sql 2005 (I think), and I'm making a scheduling program in VB that uses a database hosted on the sql server. Does sql come with archiving tools, or will I need to make something? All the other DBs on the server are 3rd party apps that have a little archiving tool as part of the utilities package. Will I have to make something like that to remove and save the old schedule entries? If so, can anyone point me in the right direction?
Thanks,
Chris
I did lot of google but did not get script for candidate and super key. I do not have syntax to create candidate and super key in sql.
View 4 Replies View RelatedWell, I can't backup up my tran log - too big. I knew enough to know you have to back it up, didn't know enough to know that tran log backup is not included in "Full backup". Contractor installation set Growth to "un-restricted". Me, too swamped to delve deeply in time to learn this is a recipe for disaster, and then it was too late - System down because tran log filled up the disk...
(Ironically, this happened the morning of the first day of some training they sent me to - Microsoft's Programming a Microsoft SQL 2000 Database...)
So, some details... The drives on the system :
___ c: size 12G, free 7G
___ d: size 44.9G, free 10M
___ e: size 44.9G, free 13G
Tran log info :
___ filename .... d:Microsoft SQL ServerMSSQLdatahorizon_Log.LDF
___ name ........ horizon_Log
___ size ........ 5606392
___ maxsize ..... -1
___ growth ...... 10
___ status ...... 1081410
___ filename ...E:Horizon_Log2Horizon_Log2_Temp
___ name ........ horizon_1_Log
___ size ........ 167168
___ maxsize ..... 640000
___ growth ...... 640
___ status ...... 32834
(there are 2 because the other totally green newbie dba added 1 the day the system went down...)
I *thought* the addition of the 2nd tran log file meant the 1st file was no longer part of the picture, and that my available free disk space was sufficient to backup the 2nd tran log file.
Clearly I'm missing something - when I try to back up, I get this in SQL server error log :
___ Operating system error 112(There is not enough space on the disk.)
:confused:___ Does that mean it's trying to backup both the 1st & the 2nd tran logs?
:confused:___ Or is it only backing up the 2nd log, but trying to use D: (with only 10M)?
:confused:___ Or, is it using C: or E:, but tran log backups need some multiple of the size of the actual log, and there's not enough space even though there are multiple G?
I've been reading & googling. So far tried to truncate both files.
( dbcc shrinkfile('horizon_1_log',truncateonly) )
No luck, got these :
___ Cannot shrink log file 2 (horizon_Log) because all logical log files are in use.
___ Cannot shrink log file 3 (horizon_1_Log) because all logical log files are in use.
:confused:
:confused:___ How do I get them to be not "in use"?
:confused:___ Must the system be down for that? (certainly seems to...)
Also, checked out the EMPTYFILE option. Books Online says :
"Migrates all data from the specified file to other files in the same filegroup"
:confused: ___ Migrates to which "other files", exactly?
:confused: ___ Is this the right way to go?
:confused: ___ If so, how would I proceed after achieving a successul EMPTYFILE operation?
Also...
:confused: ___ In the database's Properties dialog, Transaction Log tab, there's a Delete button. Could that button be used to get me out of this difficulty?
Last, but not least... If I'm going about this altogether wrongly, can I get a pointer or two?
TIA for any and all feedback...
we just moved a database from a shared SQL 2000 server to SQLExpress on a VPS server. Every thing seems to work great, really no performance loss at all, except for one stored proc that is giving us problems. It's function is to update a history table, and then update the production table. On the old server, it would take less than a second to run this, now it takes anywhere from 45 seconds to 1 minute or it times out. This database is used on a classic asp web app. ANY help at all on this would be appreciated as I am pulling my hair out trying to figure out what's wrong here. here is the proc.

cmd.CommandText = "select * from custTransaction where convert(datetime,dueDate,101) = convert(datetime,GetDate(),101)"
'Set the connect the command object should use
cmd.Connection = con1Dim da As New SqlDataAdapter(cmd)Dim ds As New DataSet
da.Fill(ds)
con1.Close()
If Not ds.Tables(0) Is Nothing ThenIf ds.Tables(0).Rows.Count > 0 Then

Note: I am veri sure that database has the data field dueDate with the value 11/16/2007 smalltimedate(mm/dd/yyyy)
Realli veri urgent Thanks so much for ur'll help
I have extensively revied both of the design methodologies and I cannot come up with a single clear reason to use one over the other!
Type - Attributes is where you have a table holding the type categories, type, a table holding the type attributes expected and then a table holding the type attribute value:
tbAutombbileCategories
CategoryID | Category
-------------------------------
1 | Car
2 | Truck
3 | Motorcycle
tbAutomobileAttributes
AttributeID | fkCategoryID | Attribute
-------------------------------------------
1 | 1 (car) | Doors
2 | 2 (truck) | Cab
3 | 2 (truck) | Capacity
tbAutomobile
VIN | Category | Make | Model
-------------------------------------
1 | 1 | Honda | Accord
2 | 2 | Ford | F150
tbAutomobileAttributeValues
fkVIN | fkAttributeID | Value
---------------------------------
1 | 1 | 2
2 | 1 | 0
2 | 2 | 1000
Now the above sure is flexible in the sence that a type of automobile can be added without affecting the database schema, but was if some attributes do not take a numeric value? How do you handle computations on attributes specific attributes? Why would I use this structure as opposed to the super type - sub type as shown below?
tbCategories
CategoryID | Category
--------------------------
1 | Cars
2 | Trucks
tbAutomobile (Super Type)
VIN | fkCategoryID | Make | Model
-------------------------------------
1 | 1 |Honda | Accord
tbCars
fkVIN | Doors |
-----------------
1 | 2
tbTrucks
fkVIN | Cab | Capacity
---------------------------
2 | 0 | 1000
Now, adding new sub types probably isn't very flexible but, now you can specify data types for each attribute instead of using sql_variant, which by the documentation cannot be used in aggregate functions and may render poor result when used with ADO.
Regardless of the method used, alot of back end coding is required for computations, what table to send the attributes, etc...
Can anyone please help me clarify. What method is best and why. So far I am leaning for option 2. More work but seems to be more flexible in the sence of customization of each datatype.
E.G., what if you wanted to specify attributes about the cap that can be supplied to trucks?
tbTrucks
fkVIN | Cab | Capacity | fkCapID
--------------------------------------
2 | Y | 1000 | 1
tbCaps
CapID | Vendor | Price | et....
Any thoughts at all? I thought this would have been a pretty damn hot topic!

Is there a way to do a super-table join ie two table join with no matching criteria? I am pulling in a sheet from XL and joining to a table in SQLServer. The join should read something like €œfor every row in the sheet I need that row and a code from a table. 100 rows in the sheet merged with 10 codes from the table = 1000 result rows.
This is the simple sql (no join on the tables):
select 1.code, 2.rowdetail
from tblcodes 1, tblelements 2
But how to do this in SSIS?
Thanks - Ken
This is probably a very silly question.I started learning ASP.net by following ASP.NET Unleashed. I am stuck where he wants me to open a connection to SQL Server database. I have just downloaded
MSDE. But I dont know where to type this code and how to run it..so as to connect to the database.
<%@ Import Namespace="System.Data.SqlClient" %>
<Script Runat="Server">
Sub Page_Load
Dim conPubs As SqlConnection
conPubs = New SqlConnection( "server=localhost;uid=webuser;pwd=secret;database=pubs" )
conPubs.Open()
End Sub
</Script>
Connection Opened!
Now do i have to change the uid to SA ? (i had to assign one when i downloaded and installed MSDE?
Thanks for the help.
Hi all,
am not very experienced in using DTS and really need your help. I have a dts package that i have scheduled to run every day. Here's what i want the package to do:
1. Check whether a value for a certain column in a certain row of a table in my database is 0 or 1. If it is 1, then
2. Run the dts task (which i have created and is working)
In other words, when the package is started, i want to execute a stored procedure or sql task or whatever, and if that returns 1 then i want to continue, if it returns 0 i want to finish the package without running the dts task. I'm sure there's a simple way to do this, but i could use your help...!
Thanks,
Elisabet
Hi All,
Can this be done and if so can you give a bullet list of the steps need to accomplish this.
I need to load a bunch of files into a stagging table. Need to loop through the files and load them.
Thanks,

Hi,
what this statement do?
does it add all the values or combine all the values.
REPLACE combine WITH lc_tran + lc_exp + lc_war + ll_boc

I downloaded SQLExpress and Visual Studio Express to my home computer.
I built a simple database, adding data through theSQLexpress admin tool.
I built a web page using MS Studio. I connected to the database and used the webpage for a few days. Then I restarted the computer. Now the web page won't open, and MS Studio won't open the MDF file in the App_Data folder.
I can still see and work in the database through SQL server Express.
The web page and the MSStudio attempt to connect to the mdf file both fail with this message:
Cannot open user default database. Login failed.Login failed for user 'KAAAK/Administrator'.
So it seems to be trying to connect as the Windows user.
When I try to modify the connection to connect through a user/password I created in SQL manager, I get a message that the user is not a trusted SQL user.
from web.config:
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|info.mdf;Integrated Security=True;User Instance=True;User ID=Admin;Password=12345" providerName="System.Data.SqlClient"/>
</connectionStrings>
That was changed from the original string created automatically by MS Studio
<connectionStrings>
<add name="stocksConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|stocks.mdf;Integrated Security=True;User Instance=True;" providerName="System.Data.SqlClient"/>
</connectionStrings>
I am sure this is some simple problem, but why would the system refuse to access an mdf file it had already been accessing.?
Thanks, Michael
Hi all, having trouble with my first sql communication. I've got hosted service with an SQL database i've populated with a row.
When it gets to the third line the page crashes with an error.
SqlConnection connection = new SqlConnection("Server=mydbserver.com;Database=db198704784;");// +"Integrated Security=True"); SqlCommand cmd = new SqlCommand("SELECT UserName FROM Users",connection); SqlDataReader reader = cmd.ExecuteReader();
is there somewhere i need to put in my username or password? or is this code just wrong
Many thanks burnside.

not sure why I am having trouble here but I am using the following WHERE clause expecting to find all rows where any one of the the three keywords are present.
....WHERE Company.L_Keywords LIKE '%metal%' AND Company.L_Keywords LIKE '%tile%' AND Company.L_Keywords LIKE '%ceramic%'
however it appears to finding only the rows where all three words are present in the L_Keywords field
This is a very simple question. How would a select satement be formated in the following example.
SELECT Grade, Student_ID, First_Name, Last_Name FROM Scores WHERE (This is where I'm stuck and I know this is not the right formatting although I wish it were because it would make my life a little bit easier.) Student_ID = 115485, 115856, 568547, 965864, etc...
I may have up to 100 specific student ids to put in this one statement. I know I can use the "WHERE Student_ID = 115485 OR Student_ID = 115856, OR Student_ID = 568547" but that would be alot of waste. Seems like there should be an easier way than using the "OR Student_ID =" for every entry.
Can someone explain another way I can do this. Thanks in advance.
Hey, I have a pretty simple question.My query is throwing an error saying "Invalid column name 'subject'."The problem is that subject is a custom column I've made, well just look at the sql:SELECT a.ArticleID, subject=ISNULL((select subject from subjects),'') where subject='some subject'

View 2 Replies View RelatedHello,
I've just migrated my access database from access2000 to sql7.0. The wizard told me there was no problem. But a simple question:
How do i open my database? Where can i see tables, fields...?
Is there no interface like the one in access2000?
Thanks in advance!
Hi there.
I am trying to use MDX code to create a measure in ProClarity. Please help!!
A store can be one of a number of ‘Brands’. The MDX segment below gives me the Sales Value of a selected item, but for Store Brand 'Brand1' only. This works fine - but how do I add a brand? That is, how do I see the combined Sales Value for the selected item for 'Brand1' and 'Brand2'?
([Store Brand].[Brand1],[Measures].[Sales Value],[Item].CurrentMember)

Hoping someone could me with an ongoing indexing question that I have.
On my site, we have over the past 5 years developed what is emerging as a fairly complicated dbase structure, as features have been added to my site and relations have increased between different database tables, there has been a need to index fields in different ways, and in some instances field indexing has overlapped. For example we may have a table that has 5 fields (field1,field2,field3,field4,field5). A need to index field1 is requried because of a query that reads:
SELECT * From Table1 where field1=XXXXX
Additionally there may be a need to for another query that reads:
SELECT * From Table1 where field2=XXXXX
In this instance an index is placed on field2....
But, for example when there is the following query:
SELECT * From Table1 where field1=XXXXX and field2 = XXXXX
Is it necessary to set a new index on: field1,field2 ???
We have made the choice that yes, in fact there is...but now over time some of our tables have instances of single fields being indexed along with combinations of two single fields that have already been indexed, being indexed together. As tables have grown to over 1,000,000 records and having up to 15 or so indexes, we realize that the number of indexes maybe degrading performance. Also, indexes vary in type, e.g INT,BIGINT,Varchar fields... In the above instance, can we eliminate the multi-indexes and improve performance over all...?
On a second related question:
In the event that two tables are joined on a common field.
e.g. Select * from Table1,Table2 where Table1.field1=Table2.field1
Is it necessary to index both of these fields in tables: Table1 and Table2 ?
Hope someone can help, as we are looking to improve the efficiency of our tables as they continue to grow.

I need help.
Our SQL Server is crashing. The Database is still recovering. I can not kill any Process when the Server crashed. I shoot down and restarted the server. Nothing to do. I can not access to the database. It is recovering. How long? I do not know. What can be the reason of the recovering? Nor the event log of Windows NT or the log files of the SQL SERVER can help me.
Here is a part of the log file

Hi, can somebody help me with some verification SQL commands that I need to run on an Oracle database?
In the Oracle table 'FEE', if the 'FEETYPE' column has a value of '3' for a record, then the 'PERCENTAMOUNT' column needs to be not null for that row - can somebody put this into a command for me so I can make lots like it?
another one I have is in the 'FEE' table, if the 'FEETYPE' column has a value of '1', the 'PERIOD' column needs to always have a value of '3' for that row - is there a command that can check the records that do/do not have this information?
Any halp is greatly appreciated :)
I was just looking for opinions on the best place to pick up SQL skills. Community college course? Online courses? Grad school? I've finished undergrad, if that helps anyone have an idea of my current situation.
View 4 Replies View RelatedHi,
I have only been working with SQL for short time. My question is probably a basic one but I would appreciate the assistance!
The scenario is I have two different tables AVCfids (on ACC database)& AVCfids (on ACC.archive database). I am trying to write a command in SQL server agent (jobs) to transfer the data on a daily basis from AVCfids to ACC.archives. The script I have created but is not working is:
Database: ACC_archives
Select * into avcfids
from server.acc.dbo.avcfids
Any feedback would be welcomed.
Regards Jeff
