What Data Type To Use For This Different Things
Jun 16, 2007
Hello.
I am a newbe in this and I tried to find the information on the msdn but could not find a god answer.
I am using VisualStudio Express 2005 and a SQL Server Express version.
In a Visual Basic application I use "radio buttons", "tick boxes", "Combo Boxes" and "Numeric Up Down".
But I cant figure out what data type to use to save the data in a SQL server.
It would be nice to have a document that maps the different data types to use in SQL Server according to what object you are using in the Visual Studio.
Thanks in advance.

Let's say a user profile page on a website contains a description about a car that the user wants to sell. The user could try to be wise and write something very short like "buy my car" or the user could write a very lengthy description of his car to convince the buyer to make the purchase.
Or somebody creates a thread in a forum or replies to a topic (much like what we do here).
In these instances, what is the most efficient manner of storing the high-character content in these examples with SQL Server 2005? Keep in mind that a user could make a 2-character post like "OK" or could write a long reply or create a huge profile. So the data type has to be efficient and flexible. Judging from the list of available types in my Express 2005, I would guess the varchar(MAX) or the text data types could be used. Or would I use some other data type?
TIA.

Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error. Dropping the index solves theproblem.Can anyone tell me why an index would cause a query to fail?Thanks a lot in advance,AmirCREATE TABLE [PTRANS] ([CHL#] [varchar] (100) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[CHCENT] [numeric](2, 0) NOT NULL ,[CHYYMM] [numeric](4, 0) NOT NULL ,[CHDAY] [numeric](2, 0) NOT NULL ,[CHTC] [char] (2) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]GOCREATE VIEW dbo.vwTransactionsASSELECT CONVERT(datetime, dbo.udf_AddDashes(REPLICATE('0', 2 -LEN(CHCENT)) + CONVERT(varchar, CHCENT) + REPLICATE('0', 4 -LEN(CHYYMM))+ CONVERT(varchar, CHYYMM) + REPLICATE('0', 2 -LEN(CHDAY)) + CONVERT(varchar, CHDAY)), 20) AS TransactionDate,CHL# AS AssetNumber,CHTC AS TransactionCodeFROM dbo.PTRANSWHERE (CHCENT <> 0) AND (CHTC <> 'RA')*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

After testing out the application i write on the local pc. I deploy it to the webserver to test it out. I get this error.
System.Data.SqlClient.SqlException: The conversion of a char data type to a
datetime data type resulted in an out-of-range datetime value.
Notes: all pages that have this error either has a repeater or datagrid which load data when page loading.
At first I thought the problem is with the date, but then I can see
that some other pages that has datagrid ( that has a date field) work
just fine.
anyone having this problem before?? hopefully you guys can help.
Thanks,

Hi,
I can populate a dataTable with type double (C#) of say '1055.01' however when I save these to the CE3.5 database using a float(CE3.5) I lose the decimal portion. The 'offending' code is:
this.court0TableAdapter1.Update(this.mycourtsDataSet1.Court0);
this.mycourtsDataSet1.AcceptChanges();
this.court0TableAdapter1.Fill(this.mycourtsDataSet1.Court0);
This did not happen with VS2005/CE3.01.
I have tried changing all references to decimal (or money in CE3.5) without luck.
I'm beginning to think that string may be the way to go!!!!!!!
Can someone shed some light on my problem.
Thanks,
Later:
It's necessary to update the datatable adapter as the 3.01 and 3.5 CE are not compatible.

We have some columns in a table where the date is stored as 19980101 (YYYYMMDD). The data type for this column is NUMBER(8) in Oracle.
I need to copy rows from Oracle to SQL Server using SSIS. I used the Data Conversion transformation editor to change it to DT_DATE, but the rows are not being inserted to the destination.
On Error, If I fail the component, then the error is :
There was an error with input column "ORDER_DATE_CONV" (1191) on input "OLE DB Destination Input" (29). The column status returned was: "Conversion failed because the data value overflowed the specified type.".

I have a field that is currently stored as the data type nvarchar(10), and all of the data in this field is in the format mm/dd/yyyy or NULL. I want to convert this field to the smalldatetime data type. Is this possible?
I've tried to use cast in the following way, (rsbirthday is the field name, panelists is the table), but to no avail.
SELECT rsbirthday CAST(rsbirthday AS smalldatetime)
FROM panelists
the error returned is "incorrect syntax near 'rsbirthday'.
I'm rather new to all things SQL, so I only have the vaguest idea of what I'm actually doing.
Thanks for the help!

I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.
I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.
I hope someone can help me work through this.
Thanks in advance,

I am using Visual Studio 2005 and SQL Express 2005. The database was converted from MS Access 2003 to SQL Express by using the upsize wizard.
I would like to store the current date & time in a column in a table. This column is a smalldatetime column called 'lastlogin'.
The code I'm using is:
Dim sqlcommand As New SqlCommand _
("UPDATE tableXYZ SET Loggedin = 'True', LastLogin = GetDate() WHERE employeeID = '" & intEmployeeID.ToString & "'", conn)
Try
conn.Open()
sqlcommand.ExecuteNonQuery()
conn.Close()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
This code works fine on my local machine and local SQL server. However at the client side this code results in the error as mentioned in the subject of this thread. I first used 'datetime.now' instead of 'getdate()', but that caused the same error. Then I changed the code to 'getdate()', but the error still remains.
The server at the client is running Windows Server 2000 UK . My local machiine is running WIndows XP Dutch.
Maybe the conversion from Dutch to UK has something to do with it. But this should be solved by using the 'Getdate()' function..... ?

I'm trying to use the SSIS Execute SQL Task to pull XML from a SQL 2005 database table. The SQL is of the following form:
SELECT
(
SELECT
MT.MessageId 'MessageId',
MT.MessageType 'MessageType',
FROM MessageTable MT
ORDER BY MT.messageid desc
FOR XML PATH('MessageStatus'), TYPE
)
FOR XML PATH('Report'), TYPE
For some reason I can only get this query to work if I use an ADO.NET connection type. If I try to use something like the OLEDB connection I get the following error:
<ROOT><?MSSQLError HResult="0x80004005" Source="Microsoft XML Extensions to SQL Server" Description="No description provided"?></ROOT>
Can anyone tell me why the SELECT ... FOR XML PATH... seems only to work with ADO.NET connections?
Thanks

I am writting a T-SQL script to install my database. I have figured out all the sets except 2 areas.
1. Give login db_datareader / db_datawriter permissions to a DB
2. Add a DTS Package, it uses a script, and schedule it.
Here's how I do them in EM....
Issue 1: Security - Logins,
Right click on login, select properties
In database access tab, check Permit for DB
In database role, check public, db_datareader, db_datawriter.
Issue 2: DTS - Local Packages
Right click on local package, new package.
Create SQL connection & exe SQL task (attach seperate SQL script)
Save
Right click on newly created package and schedule

Hello everybody ,
I want you to explain me something that i find a little strange.
Yesterday i had a problem with a huge log file and a friend in here helped me fix this by making a log back up and then shrinking it to 200 MB.Everything went fine.When i returned home i tried something else in a test environment..Here what happened:
I Got a full database back up.
I dropped the database.
I created a new one with 1GB mdf and 250MB ldf.
I vanished the log back -up
I restored the mdf file on the new database
The log file again had the same huge size after the restore.
How did this happen?
I sell my mother in law.Is anybody interested?

Hi all,
a question that has been in my mind for a while:
A HEAP is a table that has no clustered index.
Now consider a table that has a unique clustered index (primary key) on an identity column ?
For example:
create table Test
(
TestId int identity(1,1) not null,
...,
constraint PK_Test primary key clustered (TestId)
)
Is there a recognised term for such a table ?
Thanks
Graham

One interviewer has asked me the following question:
What are the things that you consider while designing database?
I have told about integrity constraints, and normal forms.
but he has added 15 more concepts like
1. indexers
2. Table columns
3. Table rows
4. search facilities
6.......
Can any one give full Idea on this question?
Thanking you Ashok kumar.

I have made a report in SRS and am not sure of how to do some of the functions I need.
In SQL I can use UPPER to convert to upper case, SRS doesn't seem to like this. The report runs but the line that is to be upper case is missing. If I remove the UPPER word from my query it works fine just displaying in lower case. Am I doing something wrong?
In Excel 2007 (I am converting my report from Excel to SRS) there is a function called NETWORKDAYS (Returns the number of whole working days between start_date and end_date. Working days exclude weekends and any dates identified in holidays. Use NETWORKDAYS to calculate employee benefits that accrue based on the number of days worked during a specific term.) Is there something similar I can use in SRS?
Thanks.

Okay,
I'm creating a small application for my local school district that will allow them to do a small management of inventory.
Is there a way to create an executable script that will create the default databases the first time? If so, what all do I need to do for the script and to make it execute?
I want to make a section in my OPTIONS area where users can put the path to their db (will not be hosted on the same PC as the software) along with the username and password for the db. I know I can store this information in a predetermined variable in the program so that it can reference it off and on.
Could someone please help me with this..... If it's in the wrong forum please let me know.
Thanks,

Good afternoon,
I've here a shell plugin and it's compiling fine and can be viewed in BI Dev Studio when choosing the DM technique using the proper wizard.
I also have here a K-Means implementation that estimates the number of clusters using a statistical semi-empiric index (the PBM index).
This implementation is done in C# and works fine. But it has to receive all the data of the database (all variables for each row) in order to do the proper vectorial calculations in a CSR (Compact Sparse Rows) way.
Besides, as you know, K-Means needs all the data at once because of the clusters mean (centroid) calculation.
So, I have some questions:
1) Where to place the call to the K-Means implementation in the shell passing as argument an object holding all the data ?
2) After this call, with the data clustered, what other objects must be modified in order to use Microsoft Cluster Viewer ?
3) I will need to create a new column or a new table on the database to specify which data belongs to which cluster. Can I open an ADO connection as I normally do in other programs from inside the plugin or is there another (easier/better) way to do so ?
Thanks a lot once more.
Best regards,
-Renan Souza

Hi all of you,
I've got a .dtproj project along with 10 dtsx packages. Up to here everything is fine, every package have its own source files, sql destinations and so on..
Issue comes when I try create a flat file source connection for the eleven one.
I get this message:
The component has detected potential metadata corruption during validation.
Error at Data Flow Task [Flat File Source [1]]: Failed to find any non-special error column in output "Flat File Source Error Output" (3).
It may not be possible to recover to a valid state using a component-specific editor. Do you want to use the Advanced Editor dialog box for editing this component?
Otherwise if I'm gonna to open a new .dtproj project separately no problem at all, I mean, appears the suitable window, "Connection Manager", "Column", "Error output" on the left and so on..
It's very strange. The rest of the packages, the same situation. Fortunately, all of them are stored on the server.
I don't get the point at all. Could you please tell me what the hell is happening?
Thanks in advance and regards,

http://blogs.conchango.com/jamiethomson/default.aspx has a lot of great tid-bits for SQL 2005. I am currently on a tight deadine for 25 SSIS packages that need to be able to move from Dev to QA to Staging to Prod. For the life of me I cannot get any of the packages to *READ* the config files created with the package config wizard. All I want to do is move the connection string out of the package so we can change the config file and not have to touch (hand edit) each package. Any help is appreciated!
