i need to retrieve column names in a rowset, let me explain a bit;
i can simply retrieve a column name by using IColumnsInfo::GetColumsInfo, but the problem is when i use "AS" keyword in the select statement such like;
SELECT identification AS id FROM test_table_a
i see alias name of that column instead the internal column name.
as you can guess the qestion is; how can i get both alias and internal name at the same time and of course what is the *usual* way to get it.
I was wondering if anyone has an idea of how we could find the table names and column names of the tables in our Sql server database at runtime/dynamically given our connection string? Please let me know.
I'm an absolute beginner in asp/asp.net. You have been warned. I managed to run and compile asp.net using win xp home edition, via Visual Web builder 2005 express edition. I managed to use its tools to create a test database and table and put values in it. Now I wish to connect to this db using my aspx page. While fiddling around I finally able to drag the "table" icon on the database pane into my aspx page and it generate a code snippet below: <div> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" EmptyDataText="There are no data records to display."> <Columns> <asp:BoundField DataField="US_ID" HeaderText="User id" SortExpression="US_ID" /> <asp:BoundField DataField="US_NAME" HeaderText="USer Name" SortExpression="US_NAME" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:nepConnectionString1 %>" ProviderName="<%$ ConnectionStrings:nepConnectionString1.ProviderName %>" SelectCommand="SELECT [US_ID], [US_NAME] FROM [USER]"> </asp:SqlDataSource> </div> When previewed in the browser, it seems to show the content of the db table. What I want to know is a sample coding on how to connect to the db the usual way (initialise the connection string, prepare and execute the query, fetch the content of resultset). Based on the code snippets above (it contains the info about the db name, table name and the column name I'm using), can anyone guide me by providing the lines of codes that retrieve the data? Basically the first thing I would like to do is fetching the data to be compared with user name and password submission after they click on login, among other basic stuff, which doesn't require bells and whistles like <gridviews> and other contraptions provided. And another thing, would the connection string or other parameters be any different from my computer if I were to upload my aspx page including the mssql db file into my webhosting to be tested live? Thanks for anyone out there willing to provide some hand-holding here!
I have spent the afternoon researching this, and to no avail so here's my question. I have a user input form with upwards of 60 fields that are to be filled in by the user (intranet environment). I want to post those values as a new record in an SQL database. I have setup an SQLDataAdapter tied to a parameterized stored procedure on the SQL server. I can successfully post data from the controls on the form when I set the parameter type to Control based. Here's the problem, though. I need to do some pre-processing on most of the values in the controls on the form. I have setup VB code (that executes when the user clicks the "Submit" button), that pulls in each control value, performs any necessary processing, and sets a variable to the value I actually want stored in the DB. How can I assign THAT value (from the variable) to the parameter for the stored procedure? Thanks, Dave
Hi, What is the simplest way to crash a sql server? Somebody asked me that question, and I was unable to give the best answer. Please help me to find it. Thanks!! Joydeep
I am interested in what the simplest was to get a query result that will only ever have one result (ie One column, one row) into a variable. An ugly way is to use a cursor that simply fetches the first row but that seems to be a horrible way to do it and it has sometimes major drawbacks sometimes (mainly if I have to dynamically choose the table). Surely there is a better way?
What do you think? A simple example would be nice.
I am researching ideas for the best way to have users enter data into SQL.
I am familiar with VB and Access Forms and HTML coding but what I am looking for is a way to have a standalone app or website where users can enter information but I want the form to have branches that change depending on user input (such as selecting a meeting type then having specific questions open up related to it).
Any ideas on the best way to do this?
If a different forum would be better for this request please advise and I will move appropriately.
Im trying to get the column names from a database and display them in textboxes. someone has already helped me by tellnig me that i need to use the FillSchema command. Which works just fine and I can see only the colum names in a datagrid when i bind it to that.
The problem is that I do not know how to extract the name of a column and put it in to a textbox ?
Hi,How do I display the column names from my Sql server table?In asp3 the recordset allowed thisforeach key in rs ColumnName = key.name ColumnValue = key.valuenextHow do I do this in .Net?I want to use a DataReader so I can read through each record and only display the ones I want.TABLE_ONEColumn_OneColumn_TwoColumn_Threethanks,
At my work, we are upgrading a number of MS Access 2000 databases to SQL Server 2000. Many of the columns have names that do not follow the rules for Identifiers. For example there are columns with a numeric names 1,2,3,4,5,6,7,8,9. There are also columns with a hyphen in the name and columns that begin with a number and not an underscore or an alpha character. Plus there are columns with names like first, last, position, etc. (There was also columns with reserved words used as the names. I have changed those column names in the databases that I have already converted) Will leaving these names alone create a problem? The database serves as the backend to ASP pages.
Instance of SQL2K5-SP1 on Server2003R2. Created two databases Test1 and Test2, create single 2-column table (tblTest)in Test1 with one row of data. Create SSIS package to transfer the table and its data to database Test2 using "Transfer Objects Task". Fails with error code 1073548784.
I have tested for security issues and don't beleive these to be the cause: I have monster privelidges and can successfully use SSIS packages to execute CREATE TABLE etc.
Have also tried most combinations of Task options (eg COPY ALL OBjects etc etc)
Have tried this on three different servers: same results.
This simple test is the result of distilling down problems I'm having with SSIS manipulating some 60G within some 300 tables, so I'd really like to use the power this task promises!
My head is getting a little sore from scratching - any advice gratefully received.
Hello,I'm still extremely novice to SQL and I've tried googling how to produce this result but I've been encountering a lot dynamic sql commands which isn't exactly what I want. If this is an ignorant question I do apologize but heres my scenario: I have a table with columns of the day, for instance: Monday_hasData (bit)Monday_DataAnd what I want to do is essentially pass in "Monday" as a parameter and rather than doing an If statement on each row, I would like to just like to do something like assign @dayCheck + "_hasData" to a variable and then use @dayCheck as part of my query. Is this possible or am I going to have to have 7 cases? Thank you for any input,Chance
Hi all, By using below query i can get no of tables having the give column name in a particular database, SELECT COUNT(*) AS CounterFROM syscolumnsWHERE (name = 'empno') but i want to know the table names too? any one please suggest me how to find table names too...... In other words i know the particular column name and right now i want to know the table names in which this column name exists.
Hi, I have a table in which out of 20 columns, there will be data only in a few columns. So, I need to find those column names which have data in them. I was able to do it using the information_schema and using a cursor to loop through all the column names and find out which columns have data in them. But i need to know if there is a more efficient way of doing this without using the cursor. Can somebody please let me know how this can be done without using a cursor? Thank you.
Can anyone help me with a SQL statement that will list all the column names in a table please ?
I just want to list out the column name so that i can develop asp/vb more effectively than having to use SQLEM and Design table to see the field names.:confused:
Hi is possible to create dynamic column name example Declare @StartDate as dateTime Select @StartDate = '2004-06-05'
select SUM(Case When table1_date BETWEEN dateadd(day,-6,@StartDate) and @StartDate then 1 else 0 end)AS [dateadd(day,-6,@StartDate)], SUM(Case When table1_date BETWEEN dateadd(day,-13,@StartDate) and dateadd(day,-7,@StartDate) then 1 else 0 end)AS [dateadd(day,-13,@StartDate)] from table1
Is there a way that you could get the column names for each table in a database using 1 query? something like: tbl colname t1 catID t1 catName t2 prodID t2 prodDesc t3 cartID ... ...
I know it would be long, but I would just be searching through the saved output for specific names.
I was wondering how would I get the column names from a table? Not the results just a listing of column names. What is the command to get this information? I am using MS Access, but I posted here because MS SQL is the closest thing on this forum and the syntax is usually similar.
Morning guys, I have a project where Iam suppose to script all columns in every database/table/columns on the network. I figured the best way to do this would be using sql-dmo (Sql Server 2000)
Does anyone have any suggestions on getting started with this project?
I am writing a stored procedure in which I have a query that selects the Headings of Columns from another table... I want to then create a loop that will contain a variable with the value of the column heading and then set the column to a value of NULL...
Is there any way to accomplish this???
I thought about placing these values into a temp table...
Create Table #UpdateRejDoc ( Abbreviation varchar(20) ) Insert into #UpdateRejDoc Select Abbreviation From tbl_Titles left JOIN tbl_TitleRouting on tbl_Titles.Title_ID = tbl_TitleRouting.Title_ID Where tbl_TitleRouting.Application_ID = @Application_ID While Exists (Select Abbreviation from #UpdateRejDoc) Begin
Set @QueryX = 'Update DBLandfillUser.tbl_ObjectApprovals' + '@AppName + Set @FieldName = null Where object_id =' + Cast(@object_id as VarChar(20)) End
Hi All, Heres my problem... If I create a table T1 with a couple of columns; MyPKCol, ColA I then create a view V1 as "Select * From T1" At this stage, if I run "Select * From V1" the result will, as expected, include following columns: MyPKCol,ColA
If I now add another column, ColB, to T1 and then again run "Select * From V1", I still get the result with only 2 columns; MyPKCol,ColA
In order for V1 to return MyPKCol,ColA,ColB I have to drop V1 and then recreate it again.
Can someone explain why this is and how I can clear this type of cache? I've tried the following commands, but it didn't work: DBCC FREEPROCCACHE; DBCC FREEsystemCACHE( 'ALL' ); DBCC DROPCLEANBUFFERS;
There has to be an easier way than having to recreate SPs, Function and Views just because you make a change to a table.
I hope I made sence Thank you in advance for any help.
I have a SQL table with 5000 rows in it. Some of the other SQL columns have different values but if I wanted to swap say 500 of the rows would it be something like
UPDATE Coupins SET Name='test1,test2,test3' WHERE Name='test4,test5,test6';
I need basically to swap the Name value of these without affecting any other values.
I'm trying to perform an insert on a table from another table, but the fieldnames are different. The data is similar, but there are less fields as well. Does anyone know how to accomplish this? All the material I've read on the Internet so far pertaining to Insert statements, has all the column names matching up.
