DataSource Controls :: How To Select A Field Value From A Database Table
Jul 5, 2010
I need to select a field value from a database table. If the value read is '1' then I need a 'Y' to display as output in the select statement. I haven't figured out how to do this yet and queries I tried that did not work.
select IsIata from Table_1 CASE WHEN (IsIata = '1') THEN 'Y'
select IsIata CASE WHEN (IsIata = '1') THEN 'Y' from Table_1
I'm implementing a BLL layer and have a few questions. First, in my DAL, there is a contacts table, the select method is a sql query against a sql server 2000 database. The preview data returns everyting as expected. The query is
[Code]....
The BLL method is built like so
[Code]....
When using the BLL method to a gridview, the results of the subquery are not displayed. There are also other methods, each having a different where clause for ContactRole_ID and each is having the same issue of not displaying the subquery reult in the gridview. No error, but no data is displayed for the subquery either. Here is the templatefield of the gridview
[Code]....
Another item that is causing an error is in trying to update a record. Here is the DAL update method
[Code]....
And the BLL update method
[Code]....
The error says i have extra parameters, but have no clue where the extra parameters are being picked up. The error isObjectDataSource 'odsContacts' could not find a non-generic method 'UpdateContact' that has parameters: _ContactID, _Active, _ContactName, _Office, _VirtualOffice, _Pager, _Fax, _Home, _Cellular, _Email, _ContactRole_ID, Active, ContactRole_ID, ContactName, Office, Email, VirtualOffice, Pager, FAX, Home, Cellular.And the objectdatasource

I have a form that submits one entry to a 'Listings' table and multiple entries to a 'ListingLocation' table depending on how many cities the user selected. When the listing is created, I need the auto generated 'id' field to input into each of the the listing rows of the 'ListingLocation' table. This seems like it should be simple but I cannot figure it out. I currently have it hardcoded to enter '22' where I need it to enter the listing id.

I have to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records. Now I want to retreive all record except 1-1 record left in each type, so it will return 14 records in result.
I need to display the table name in the select statement. how?
exact question:
we have common columns in two tables. we are displaying the records by using
select column_name from table_name_1 union select column_name from table_name_2
But the requirement is, we need to display the source table_name along with the data. consider a,c are present in table_1 and b,d are present in table_2. we need the output in the following way
eg: column_name table_name a table_1 b table_2 c table_1 d table_2
I have a table added to a dbml file in my website. The website is already deployed to Live server. Now I have been instructed to a add a new field to the table. The field will be defaulted as getdate().
I don't plan to modify my dbml file for this change since the filed holds a default value. Will it cause any issue(performance related or any other). I am sure that I will not have to use the newly added field in the website. I am new to LINQ.
I am using a CustomSiteMapProvider to draw the SiteMap from a MS SQL database table. If I select all the rows in the SiteMap, everything works correctly. I now want to select a subsite from the SiteMap and display it and this subsite's subsites only. I am using recursive SQL to do this. The code below works correctly except the root record, record number 286, is not included in the result:
[Code]....
How do I include the root record, record ID 286, in the result?
I have set up Linq to sql. I now need to fill a formview with a select that does a join across a few tables. Have not been able to find any example or tuts that go beyond the simple select. Any suggestions? Can this even be done?
I have a table in SQL where I insert data (CatCodes) using C# code but I want to insert ID code (DealerID) with it as well. Following is my Stored Procedure and C# code:
[Code]....
C#:
[Code]....
As you can see, I am insering CatCode values in Categories table using string cbspecialities.
How can I insert DealerID the same way? DealerID is automatically generated in tblDealers table when "InsertExternalInfo" asp.SqlDataSource control runs "InfoInsert" SP.
I am trying to update my table ARTICLES and it has a field COUNTER, Everytime a user enter this ARTICLES, the page_load event runs a LINQ to SQL query taking the QueryString as parameter, increasing the COUNTER field in 1.
I have a table in my aspnet database. I added a bottom row "Not Selected", if the user doesn't select from a databound drop down list. This row is at the bottom, because I just added it to the table data. Is there any way to move this one row to the top of the table manually? There is not "cut" and "paste" when I select the whole row.
I have a insert into statement thats inserting my numbers from a numeric text box on my aspx page. I am choosing the Amount Type then putting in a a number.
So i have a drop down that i select example Direct Charge then i enter 600.00 and click add it puts that in to the databse for me woot..
I then put in say Misc Credit and enter 200.00 it inserts in that into the database woot.
The look up table that has my amount types has a field called numeric opperator which is either + or - the Credit being a - and the Charge being a + then my stored procedure takes all my + numbers and adds them up and subtracts all the - numbers.
I want to change that so that it actuall be inserted into the table as a - number form the start. So I want choose Misc Credit enter 200.00 and click add then my event says o yea thats a credit insert 200.00 as -200.00
