DataSource Controls :: Add Data To The Tables After They Are Created?
May 4, 2010
I have created a database along with the tables. The tables have the primary and foreign keys to create the relationship between them. However, I cannot now add the data to the table rows due to the key constraints. How do I now add the data to the tables without making up arbitrary data for the table ID's?
I have been using LINQ to SQL for quite a while (about two years). Every thing was fine until now. As usual, I created LINQ to SQL classes and built the project, then created an aspx page. However, I cannot see the DataClassesDataContext in the code behind file. It is not listed in the intellisense list.
I just can't wrap my head over this and don't have enough time to read long articles.
I already have an HTM Table on my form. I dynamically create New Roows and Cells and keep adding them to the Table .
The cells Contain Labels, Textboxes, Drop downs and Buttons. I also add Handlers to the dropdowns
The form loads perfectly the first time. But when I change the value in a drop down, on the postback, I get a msg saying that " There are multiple controls with the same name 'txtCheckin' . How do I handle this?
Apologies if this is in the incorrect forum.. just a question about how to best structure some tables for a particular presentation of data. In the following table (2nd column) you'll see that each motorcycle product applies to a range of years. What is the best way to store this range of years in a relational db? At the moment I have a datefrom and a dateto field for the two ranges, but that may complicate things when I want to filter the table by a particular year. E.G. datefrom is 2006 & dateto is 2010 and I would like to filter by products for a 2008 model.
I have a details view form inserting data into one table successfully with no problems and picking up the ID parameter from a session.
What i would like to do is one insert SOME of the fields NOT ALL get inserted into another table.
Table 1 = course
table 2 = matrixoneantwo
I tried creating a datasource which inserted data into Matrixoneanttwo and called it from the detailsview_inserting event (sqldatasource.insert() but then i realised that this data source is seperate to my current one and therefore cannot use its parameters.
I need to synchronize data between 2 tables. i need to update records on table2 corresponding to table1. I also need to add new records in table2 by getting new records from table1.
Adding data into kartlar table (RehberID,KampanyaID,BrimID) is ok. But which Kart'ID created? I need to learn which Id created after adding data (RehberID,KampanyaID,BrimID) into Kartlar?
[code]...
How can I do that? I want to get data from Kartlar which data I added?
i have an insert statement, and what i would like to do iswhen the value of table1 is entered, that value enters into table 2, so for example, heres my insert statement
INSERT INTO Cards (Name, Desc, id) VALUES ( @Name, @Desc, @id) INSERT INTO CardTP (NameSet, Desc, id)
Now, what i would like to do is that, i will specify all those individual values myself, BUT, when it now comes to the "id" field, when an id is entered for the "Cards" table, the SAME id should also be entered in the id column of the "CardTP" table. how i could enter the value of one table, into another tables row (having the same value) as i want the Cards and CardsTP table to be related in the id fields.
I have hard time trying to find the solution to retrieve data from multiple tables in one database.
table Kategorije has fields: idKategorija, naziv, opis table Clanak has fields: idClanak, idKategorija, naslov, autor,...
Kategorije.idKategorijais joined with Clanak.idKategorija, but that isn't the solution because I want my web site to show the Kategorije.naziv instead of Kategorije.idKategorija. This is the code I'm currently using to get idKategorije shown on my web site:
I am writting a directory website that advertises fitness classes. These classes are listed by Class Type, and Geographical Area. Each Class Type can satisfy one or more of four Fitness Goals such as Loose Weight etc...
I have a table for Classes (classid, classname, classdesc, classtypeid, geoareaid) I have a table for geographic areas (geoareaid, geoarea) And I have a table for ClassTypes (classtypeid, classtypename, classtypedesc)
Which obviously links geographic area via the classes.geoareaid as a forgien key and classtypes by classes.classtypeid as a forgien key.
I can list all classes by type and also by geo area no problem, the problem arrises when I then also want to filter by goal.
The Goals Table (goalid, goal, goaldesc) is linked to the classtypes table via another table classtypes_goals (classtypeid, goalid) as each classtype can satisfy any of the 4 goals.
I am using a DataSet to fetch the data from a Stored Procedure in the SQL Database but because the classtypes can be linked to multiple goals I am getting duplication in my list depending on how many goals a classtype satisfies.
All I need in my data list is class name, class type and area I don't even need to display the goal I just want a drop down above the table that will filter the list and show only classes of classtype that satisfy the goal chosen.
I'm looking for ideas on deleting data from the multiple SQL tables with LINQ (C#).
My existing solution does the following:
1. DeleteAllOnSubmit( Subset of the data from the child table)
2. DeleteAllOnSubmit( Subset of the data from another child table)
3. DeleteAllOnSubmit( Data from the parent table)
4. CommitChanges()
All this resides within a single method, which makes it ugly and not re-usable.
I have considered the following alternatives, but I decided not to use them:
1. Cascade delete on the tables.
2. Do a join on all tables from which I will remove the data, but I'm not sure yet whether I could pass a join query to DeleteAllOnSubmit().
3. Write stored procedure(s) to delete data from each table. I don't have the time to implement this due to a large number of tables and the time constraints.
I need to retirve data from two tables...when i click a value in dropdown list, i need to retrieve values from two tables based on that id( which i have selected in dropdown)..so when i have written query ( "Select assign_issue.issue_assigned_to, assign_issue.created_on,assign_issue.last_Date, issue_register.issue_desc,issue_register.issue_Priority from assign_issue INNER JOIN Issue_register ON assign_Issue.Issue_ID = issue_register.Issue_ID where issue_register = '" + ddlissueid.selecteditem.text + "'")..query is executing ..when it comes to dr = cmd.executereader()..Dr is unable to read..it is showing false when i trace..unable to read into while loop.
I'm using below stored procedure to reterive data and i'm displaying it in datalist... Now i want to reterive data from two tables by using this stored procedure...collegedetails is my table name... I want data from coursedetails also.

After creating a dataset, which has CRUD statements generated two or more tables, which Data Control should I use that will allow me to insert data into fields into 2 or more tables from a single web form. I'm trying to create a web form that will allow the user to input student information, such as general information, medical information, etc.
My dataset table data is from multiple tables (showing on a gridview),How to update the database tables using batch udpate on clicking submit, if the data is from a signle table, no problem, but I am not sure how to handle if the datais from mulitiple tables? If I have related tables, do I need put them in differet tables in the dataset?
Lets say that I have a database set up with a load of info in it and I decide I want to add the membership and roles functionality to my site but my hosting provider makes me pay for each database I use. I don't want to pay for another db, so how do I set it up so that instread of creating membership and roles tables in the the aspnetdb database, it creates them in my existing database?
