I trying to fully understand when to use different data types in sql server.I want to know what Microdoft means when they say"Varchar is the actual length of the data entered plus 2 bytes".example e.g. what would the storage of varchar (50) be?

I am developing an online web-based address book for multiple users. There are STANDARD FIELDS and CUSTOM FIELDS.
Standard fields include: Name,Street,City,State,Zip.
Custom fields are those defined by a specific user. For example:
User-A Custom fields:
Interest Rate <real>
Loan Amount <currency>
Start date <date>
User-B Custom fields:
Blood type <char 3>
Date of birth <date>
Referred by <varchar 50>
Different users can have different custom fields in their address book. As you can see, while the standard fields for each user can be
stored in a single table. However, I have several methods by which I can store the CUSTOM fields.
------------------------------------------------
Method 1: Create 2 separate tables called CustomField and CustomValue:
CustomField has fields:
FieldID <int>
FieldName <varchar 25>
UserID <int>
CustomValue has fields:
ValueID <int>
Value <varchar 50>
FieldID <int>
------------------------------------------------
Method 2: Create a separate Field and multiple Value tables for each data type:
CustomField, CustomCharValue, CustomIntValue, CustomMoneyValue, etc...
CustomField has fields:
FieldID <int>
FieldName <varchar 25>
FieldType <smallint> (determines which TABLE, below, contains the data)
UserID <int>
CustomCharValue
CharValueID <int>
IntValue <Varchar 50>
FieldID <int>
CustomIntValue
IntValueID <int>
IntValue <int>
FieldID <int>
etc....etc...
The structures of those tables would be similar to Method 1, but the data would be segregated based on their data type.
--------------------------------------------------
I'm thinking that while Method 1 will be easier to implement, Method 2 may offer me better performance if coded correctly. I'm going
to assume that I'll have at least 1-5 million records to work with over the course of my first year and I will need the ability to sort
records based on values in the custom fields as well.
My first question is: Which method should I be considering and is there an alternative or hybrid that I should be considering?
My second question is: What statements should I use in my stored procedure that will enable me to retrieve a list of USERID, CustomFieldIDs and their values as one resulting table that I can query at will and with solid performance?

I get this error:
The data types text and text are incompatible in the equal to operator.
when trying to execute this query
SELECT id FROM users WHERE username=@userName
Any Ideas?
Hello all. I am a newbie to the world of setting up SQL databases, so please forgive my ignorance.
I have a nice website for social workers to enter encounters with clients. The social worker has to provide very detailed notes about the encounter. I have set up a textarea to take in all of this information. I am wondering which is the best data type to use for the table that this information will be dumped into. I am currently using text, but I don't want to waste space on the server with whitespace. Is this the best way to go? It is not uncommon for upwards of 5000 characters to be entered. This site is powered by ColdFusion, if that makes any difference.
Thanks in advance,
Adrian Miller
i have created asp.net page, one feild of this page text area.

I have to run a dynamic sql that i save in the database as a TEXT data type(due to a large size of the sql.) from a .NET app. Now i have to run this sql from the stored proc that returns the results back to .net app. I am running this dynamic sql with sp_executesql like this..
EXEC sp_executesql @Statement,N'@param1 varchar(3),@param2 varchar(1)',@param1,@param2,GO
As i can't declare text,ntext etc variables in T-Sql(stored proc), so i am using this method in pulling the text type field "Statement".
DECLARE @Statement varbinary(16)SELECT @Statement = TEXTPTR(Statement)FROM table1 READTEXT table1.statement @Statement 0 16566
So far so good, the issue is how to convert @Statment varbinary to nText to get it passed in sp_executesql.
Note:- i can't use Exec to run the dynamic sql becuase i need to pass the params from the .net app and Exec proc doesn't take param from the stored proc from where it is called.
I would appreciate if any body respond to this.

Hi,
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped:
[Department, DEP_CLEGALCODE]
One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
thanks.
Howdy,
Can some one please explain how the storage of a huge text or ntext object ( say a string of characters 100 KB in size ) is carried out please?
With a data page maximum size of 8000 bytes, how does SQL handle the storage of such an string - it would obviously obverlap multiple rows etc.
Does the application writing it to the database have to split the object over multiple rows and manually keep track of which bit is in which row so it can be re-created later in correct sequence by adding the bits back together, or is it done some how differently?
Any help most welcome as this is a bit confusing.
Cheers,
SG.
How to implement distinct storage tiers on SQL Remote BLOB Storage (RBS)?
I want to use this SQL Feature to move files(images, videos, pdf files) from a database to a distinct database dedicated to RBS. Then I want to have several storage tiers, where objects will be saved and moved according access frequency. Old data will be arquived in cheap storage, but it must be always accessible if needed.
Description:
- 1st and main tier: new and frequently accessed objects stored in high performance storage;
- 2nd tier: automatically move older or less accessed objects to an inexpensive and different storage tier;
- in all cases, all objects must be accessible to all users, but accessing to archived objects(2nd tier) will be much slower;

Hi All,As per BOL, XML data type can store up 2 GB of data.My question is when a row is inserted in a table, for its xml column,2GB of space will be resered.In other words, how xml is internally stored. Is storage allocation issimilar to varchar(max) data type?Thanks in advance for everything.
View 1 Replies View RelatedI am planning on doing database mirroring using two (2) servers for each instance and a SAN to store the data and log files for both the primary server and mirrored server. How do I arrange the SAN 4 Physical Drives?
My options are:
· 2 Raid 1 Mirrors giving 250 GB to each SQL engine €“ This though has both the transaction logs and data on the same physical drive even if we split it up further into logical drives
· A Raid 10 - The transaction logs and data can be on separate drives
· A Raid 5 using the 4 Drives. (How SQL will see these drives I€™m not sure when it€™s 2 SQL engines)
· Or I could get a 5th drive and have a mirror set for transaction logs and a RAID 5 configured for the data.
Hello, So, here's my dumb question; if I wanted to store some *.gif images in some database (SQL2K possibly 2K5) field and wanted to pull the information from that to display on the web form, am I actually storing the image in the database or am I storing the location of the image in the database?I ask this because I was under the impression that the location to the image file is what was being stored but another person was saying that it was the actual image. I guess I'm confused... Thanks in advance....

Hello there,
Don't know if this is the right forum to be asking this, but I'll give it a try...
I'm relativelly a beginner in SQL Server and T-SQL in general. The problem I'm trying to solve is the following:
The big picture is that I have data coming from different data sources which I need to store on a database for later reference. Each data source might have a different set of measurements. For example, data source 1 might log Pressure and Humidity while data source 2 logs Pressure and Temperature. Once the data is present on the DB, the users can go ahead and retrieve data for a given [datasource/measurement/time interval] to generate reports or charts.
My implementation so far consists of two tables: series_info and series_data. series_info holds general information for a given series of measurements for a given data source (Pressure for data source 1, Pressure for data source 2, Humidity for data source 1 and Temperature for data source 2, in our example). Each series has a bigint index as primary key.
The table series_data contains all data relative to the series from series_info. Each piece of data has a bigint as a primary key, an associate time (which is always crescent) and a foreign key to the series it represents (in series_info).
Alright, everything is cool so far. However, whenever a user wants to retrieve data for given [data source/measurement/time interval], this takes very long, since all data is interposed in series_data and for every search it's necessary to find where the desired data actually lies.
One obvious solution for this would be to dynamically create a new table to hold the data for each series, but that would just make my database disorganized, since there would be thousands and thousands of tables.
Another thing that comes to my mind is to create a table with information of where lies the data for a given [data source / measurement] for given dates. So when the user requested data for a given [data source/measurement] between, say, january and february, we would first look at this intermediate table and find out that the data lies between indexes 1000 and 2000 on the series_data table, so the next SELECT command to series_data would already contain a restriction like WHERE index>=1000 and index<=2000. This should probably improve the speed of retrieval.
What do you guys (or girls) think? Maybe there's simply a classical solution for such a case.
Thanks in advance!
Hello,
I am designing a program for work with SQL Server express 2005. But I don't know what is the data storage limit in this version of SQL Server.
What i want is storing about 30000 records in a table of the database.
Hasn't SQL Server express 2005 any problem or restrictions for storing the data?
Please advice in this regards,
Thank you,

1) When i used both Korean server as my webserver + database server then there is no problem to add Korean Data to SQL server On korean OS.
2) But when I try to user English OS server as my webserver and Korean Os server as my database server then I am not able to store Korean Data in Database server insted of it stored some mis/junk/acssi characters in database.
-- I allready try with Korean version of MDAC of English os
-- I also try with OEM feature in SQL server client network utility
-- When I am use CODEPAGE in my .ASP page then data storage work fine .. but at the time of getting it back there is problem.

I am a Windows developer for the IBM Tivoli Storage Manager Server (TSMS) product.
Our product installation is built with InstallShield and uses the Windows Installer.
On a new installation of Windows 2003 x64 Storage Server R2, at a customer's site, the TSMS product fails to install.
The install of the OS has version 3.01.400.3959 of the Windows Installer and I see no newer version that installs.
Part of our product is 32 bit (console) and another part is x64 (server).
When installing I can see that the install's default is being redirected/reset to C:Program Files (x86)TivoliTSM after it is explicitly set by a custom action to ..Program Files.. . I further observe that our custom actions to write 64 bit registry entries are being refused.
REGSAM samMask = KEY_ALL_ACCESS;
if ( regIsWow64Process () ) samMask = samMask | KEY_WOW64_64KEY;
lStatus = RegCreateKeyEx( hLocalConnectKeyRoot,
szSubkey,
0L,
NULL,
REG_OPTION_NON_VOLATILE,
samMask,
NULL,
hKey,
&dw ) ;
The above fails to create the key.
We have tried four versions of our TSMS spanning many changes but the install acts the same.
This does not happen on any other Windows OS we test on but we do not test on Windows 2003 Storage Server R2 being that it is an OEM product. We did test on Windows server 2003 R2 x64 and do not see this problem.
Do you have any suggestions on how to tackle this problem?
I have full installation traces but can only see that the registry work is being refused. I can't see why.
I am trying to find a reference for a client that lists the fields available to be substituted into a data driven subscription from the query, along with the expected data types.  For example, the field on whether or not to include a link to the report seems to be expecting a bit data type.I have searched and can't seem to find anything.  I guess I could walk through the interface and try different data types, but if  a list exists, that would be better.Â

View 6 Replies View RelatedOne of my report has different data types like decimal,percentage and integer values.
When I exported the report to excel , all the values are showing as "general" data type.
How to get excel data type same as ssrs report data type by default when exported to excel?
I Have a table with #Sample like below
=================================
#Sample
id int,
SSN varchar(20),
State varchar(2)
Â
Sample Data:
ID SSN STATE
1 999-000-000 AB
2 979-000-000Â BC
3 995-000-000Â CD
=================================
We used filter logic based on the SSN & State.
We are passing these values through variables like
Declare @State varchar(2)
Declare @SSN varchar(20)
While run time these values are lets suppose @SSN = '999-000-000' & @State='ABC'
Now the Result is displayed with the state data Like 'AB' only.
Output: 1 999-000-000 AB
instead it should give system generated error.
Here I have 2 Questions:
1. Why it is taking 1st 2 Charecters?
2. Why it does not have any system generated for length?
I can do validation with Length function for these 2 variables however if have 100 variables then it should not feasible case. So, what is the reason behind?Â

I am using the same data names from the mainframe (like XDB-NAME to RDB-NAME).

Ok so facebook groups have 100,000's of members. Members can be part of an unlimited number of groups, and a group can have an unlimited number of members.
Comma Deliniated String seems absurd. Many-2-Many Database relationship seems like it won't scale well t the 10's of thousands and 100's of thousands of members (especially if you have 1000-5000 groups). A table for each group would work but thats a bit over the top in my opinion. XML file doesn't seem to be any better than the above options.
I am no database guru, but I can't figure out a scalable method of doing this, be it with or without a database. I need something that can support 10 groups that have 20 members each OR 1000 groups with 100,000 members each.
Any help, suggestions, or kicked in the right direction would be most appreciated.
I need to generate a report of DTS package results, i. e. succeed, fail, error, etc. What tables is information of this type stored for SQL 2000?

SQL Server 2000, ASP.Net 1.1
I've been writing this stuff for a while, and can't seem to come to the
conclusion of how I should be retrieving data and assigning this data
to variables.
Since i'm using SQL Server, I'm convinced that I should be using the
datareaders GetSqlDouble (or whatever) function, but this would mean i
need my local variables to be one of the SQL types. The problem
with that is, that there will have to be lots of conversions done by me
to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order
to retrieve them correctly (Null values included), I need to retrieve
them with GetSqlDateTime(), then when it comes time to display the date
in a table, i must first check for nulls, then convert to a
string. This seems to be very cumbersome. Would I be better
off just using GetDateTime(), and the .ToString method, and ignoring
Sql Types all together?
so, basically, how are you guys using your sql server data? with
the supplied sql types, and doing all of the post-processing work
manually? I feel like i'm having trouble conveying my
issue...hopefully someone knows what i mean....i'd just like some
direction to save trouble in the long run, since i feel like there's
got to be a better way...
Confused!
Thanks,
JJ
