i want to learn about the meanings of the different 'data types' in VS 2005 (database) i.e. 'nvarchar(50). could you please advice me of a good site (reference) to read.
View 1 RepliesI'm trying to read a data table with all text fields using C# in ado.net. However, when my query runs, it always returns this error:
"The data types text and varchar are incompatible in the equal to operator. "
The SQL statment is "SELECT field1, field2 FROM table WHERE field1 = 'value'"
If I leave out the WHERE clause, it runs fine. There are NO varchar fields in my entire table (It's a test table). I've tried using both parameter objects and Convert (See commented section) with no luck. A packet trace shows the SQL string is being delivered in tact and the SQL server is returning the error. I don't know if it's a C# client issue, or a SQL Server 2005 Exp issue. The table was created using MS SQL Server Management Studio Express I'm currently using the SqlClient object like this:
<script runat="server">
DataSet dsData = new DataSet();
DataTable dtData = new DataTable();
void Page_Load()
{
string strConn = ConfigurationSettings.AppSettings["authstr"];
string strSQL = "SELECT User_ID, User_Name FROM USERS1 WHERE User_ID = "'bobhope'";
//string strSQL = "SELECT password_fld, pharmacy_fld FROM Esker_Tbl WHERE CONVERT(text, username_fld ) = '@prmuser'";
//SqlParameter spuser = new SqlParameter("@prmuser", SqlDbType.Text);
//string struser = "bobhope";
//spuser.Value = struser;
try
{
SqlConnection Conn = new SqlConnection(strConn);
SqlCommand Cmd = new SqlCommand(strSQL, Conn);
SqlDataAdapter Adp = new SqlDataAdapter(Cmd);
Conn.Open();
Adp.Fill(dsData, "USERS1");
dtData = dsData.Tables["USERS1"];
dgData.DataSource = dtData;

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.
Hi,
I´m building an aplication with VB.net and SQL Server 9, but in the future it will be compatible with PostgreSQL (by another developer), so my question is, if anyone knows what "data types" in SQL Server 9 i must use to maintain compatibility with PostgreSQL, so that when the time come for the conversion i don t have to chage the "Data Types" on each table.
Any help would be apreciated.
I have a simple Integration Services project and the problem is that decimal fields are importing as real (I'm loosing the digits behind the decimal point).
The project contains a data flow task importing a flat file (.csv) to an SQL Server destination. My .csv file has two decimal type fields. Example:
Field 1: 12345.67
Field 2: .123456
My database table that I'm importing to has two fields. The only way that I can get this data to import is to define the fields as "float" in both the text file and database table. I want the database table fields to be defined as decimal or numeric, not float:
Field 1: decimal(7,2)
Field 2: decimal(6,6)
When all fields are defined as decimal (in both the flat file and database file), I get the following results:
Field 1: 12345.00
Field 2: .000000
How does one import decimal data from a flat file (.csv)?
Thank you in advance!
I trust you'll bear with an SQL Server newbie with what may seem a rather inane request. I am designing a web app in Web Designer 2005 Express with SQL Server Express. Unfortunately, I'm finding a little confusing with some of the data types when designing tables. I have tried to find information on the various Microsoft sites (general site, MSDN, here) and while I found one document that had a table comparing data types in different implementations of SQL, it wasn't at all helpful. Most of my confusion is with the various string and char types; the numeric types seem pretty straight forward for the most part. However, it might be helpful to know the difference between money and smallmoney/datetime and smalldatetime, particularly space/size information and formatting options (unless the latter is up to the interface). It would also be helpful to know which string/char types correspond to any counterparts they might have in, for instance, Access (with which I am already quite exprienced). Or any particular quirks or idiosyncracies they might have. I don't expect anyone to write a full tutorial, but if someone could point me in the direction of a good online doc, it would be most appreciated. You might well ask, why not use Access databases? I would answer...I like to learn new stuff!
Thanks much.

View 1 Replies View RelatedI'm under the impression that this is a bad idea! A primary key should only mean one thing and shouldn't be this type of ID or that type of ID. People on my team are not in agreement and want an attribute table designed that would hold a CustomerID or a text based product sku. 'They wouldn't overlap ever' - probably true. There would also be a lookup Type column which would point to another table which holds a description how how that ID works.
Problem is, what if I want to look at the table to find customers with a certain attribute? Now I'm scanning more records than intended, OR, I'm making a hard coded lookup type ID list to look at just customer spec'd records. There's no quick way to identify just the customer records. I really am not for this route, but am I just trying to be too 'normalistic'? Would adding an identifier in the type lookup table to signify whether it's used for a customer or product sku help at all? Having one table eases the amount of CRUD procedures and puts it in.. one table.
Could people please share their thoughts and experiences with this, and why go to one way or another? (and if you're in argeement with me, how can I convince the team/superiors?)

I read some articles in the websites and MSDN about this task and I am very confused about "How to Work with Output Parameters & Report their Values in VB Forms": (1) Do I need the Form.vb [Design] and specify its properties of the object and classes I want to printout? (2) After the SqlConnectionString and the connection.Open(), how can I bring the value of @percentage to the Form.vb? (3) The following is my imcomplete, crude draft code:

Public Class Form1
Dim connectionString As String = "Data Source=.SQLEXPRESS;Initial Catalog=pubs;Integrated Security=SSPI;"

I am working with a legacy SQL server database from SQL Server 2000. I noticed that in some places that they use decimal data types, that I would normally think they should be using integer data types. Why is this does anyone know?
Example: AutomobileTypeId (PK, decimal(10,0), not null)
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

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
Is it possible to easily copy data from one table to another if the data types don't match. I know you can do a INSERT INTO table1(col1,col2) SELECT (col2,col7) FROM table2 if the data types match but is there a way to do this if they don't. I'm not trying to copy date times into bit fields or anything. I just have an old table that I built when I really didn't know what I was doing now I at leastthink I have a better understanding of what data types to use, so I was wanting to move the data in the orignal table to my new one. Most of the fields in the olddatabase are text datatypes and the new database is nvarchar(50) data types. Thanks for any suggestions.
View 4 Replies View RelatedHello,
I have a really dumb question regarding SQL data types. I have a couple columns in a table that are specified as MONEY. These columns are being read from my web app and displayed on the website for reference when filling in other information.
My problem is that when it is displayed on the website it give four decimal places instead of two. For example I want it to report $33,000.29 but what is actually displayed is $33,000.2965.
How can I set up either SQL or my web app so that it only displays the two decimal places? I've looked into changing the datatype already but SMALLMONEY and MONEY have the same type of decimal values.

I'm just getting used to using SQL 7 Database and am looking for some recommendations on what DATA TYPES to use when designing tables.
The site I am working on now uses cold fusion to enter, update, and insert mainly text and articles. Now the problem with the articles is that some of them are pretty big. And when inserting or updating them, if they go over the limit of characters I get an error.
I know in access I used to use the data type "MEMO" and be able to put a large piece of info in that field.
What's the equivalent for SQL server databe?
What are the most used/common or recommended data types that should be used when putting tables together?

Hi,
I am pretty new with SQL and was dabbling in a test database that is linked with a software application.
I made a change to a table - Lets call this (Table1).
Table1 has a multiple columns.
Column1 is defined as numeric(9)
Column2 is defined as varchar(20)
In this case, I wanted to make all values in Column2 = Column1 that did not have a value defined so I ran the following query:
update Table1 set Column2 = Column1 where Column2 = ''
This took effect but the particular software application doesn't recognize these values because they are the wrong data type.
How can I convert all data in a column to varchar(20) if it is another data type (i.e. in this case numeric(9))?
I've tried in Enterprise manager to redesign the table and adjusted the length to 21 and then back and saved it but this did not work. I was looking at Convert and Cast functions but don't know how to write one to accomplish what I need to do here.
Half of the data in Column2 is varchar(20) and half is numeric(9).
I want all to be varchar(20).
Thanks,
