I am mapping a stored procedure to an entity by right clicking on the entity (in the .edmx) and selecting "Stored Procedure Mapping." This brings you to a Mapping Details - "Name of Entity" Window that allows you to select the insert, update, and delete stored procedures associated with the Entity. It also maps the stored procedure parameter to the Entity "Property" (Column).
I'm gettin an error "error 2042: Parameter Mapping specified is not valid." The cause of the error is fairly obvious, in the Insert stored procedure that has been selected, a 'CHAR' parameter is being mapped to an Int32 Entity Property. I altered the stored procedure parameter to match the entity, I deleted the stored procedure, readded, and reslected it as the Insert function. I also cleaned, validated, updated model from database. No matter what I do, the parameter list in the mapping details doesn't reflect the change to the stored procedure. It's stuck on a char --> int32 mapping, even though it has been changed, like it's buried deep in meta data some where.
How do I use a stored procedure to change one or more (but not all) fields of a entity in EF4? I have a stored procedure "ChangePassword" taking a username and and a password as parameters and a User entity containing properties for Username and Password as well as other properties. I want to be able to use this stored procedure from a function to update the password from a function in one of my repositories. How to do this?
I am new to entity framework , it is really very good , but I want to know what is the difference between using entity framework with stored procedure or without stored procedure , which one the faster and what is the benefits for using stored procedures with entity framework.
I have a aspx page that only has a button and a button click event.
My code behind looks like this
This code works fine if I have no insert stored procedure mapped to Table UBOtest in the EntityDataModel.However, when I map the stored procedure to the EntityDataModel and add UBOtestinsert I get an error that reads "An error occured while updating the entries. See the inner exception for details.">/P> Then the innerException message is "Invalid object name 'UBOtest'
Here is the stored procedure [Code]....
I will enclose to screen snapshots...the first my mapping screen. the second is when I right click stored procedures in the Model Browser and right click stored procedure UBOtestinsert. -- it does not show any columns....should it?
I have a table in my database with a one to many relationship to another table, which has a relationship to a third table:
This seems to work fine. My question to you good folks: Is there a correct way to do this? I tried following the making a custom model binder per the blog link I posted above but it didn't work (there was an issue with reflection, the code expected certain properties to exist) and I needed to get something going ASAP. PS - I tried to cleanup the code to hide specific information, so beware I may have hosed something up.
I have a stored procedure that generates a float value. I've added the stored procedure to my edmx file and created a function import, but the function isn't showing up in the object browser or via intellisense.
I'm using Visual Studio 2010 and I've verified that the stored procedure works in SSMS. Here is the current stored proc I'm using:
I have a stored procedure that search a view using full text.
I'm trying to map the results to an existing Entity (Sales), where I mapped the column MivType to SaleType (as it makes more sense, and I want to keep db names away from my web site). The stored procedure is mapped to a Function Import, and I've defined its ReturnType to Sales.
This work well as long as the entity has the same property names as fields names.
Here's my problem: when I change the property's name, I get the following error after running the imported function:
The data reader is incompatible with the specified 'Model.Sale'. A member of the type, 'SaleType', does not have a corresponding column in the data reader with the same name.
I can fix this if I change the property 'SaleType' to 'MivType' on the entity, but why should I do that? Isn't that what the mapping is for?
This means I have to use the exact same names on the stored procedure and the entity, so in effect, the mapping is ignored (I have names like YzrName, MivYaad, etc, and I don't like it).
Is there a simple way around this? I don't want to use the db names on my application, and prefer not to change the stored procedure...
am new to entity frame work and having a hell of time building a stored procedure that insertsa value into a table using a Scalar stored procedure and returning the new ID which is a Unique Identifier. I am trying

I have built a web app and want the user to be able to select, update, delete, add data as well as execute stored procedures, I thought that I would get this from the db_datareader and db_datawriter roles but I get an error when trying to select data etcFor instance I get an error when trying to run the stored procedure ups_AddCustomer when the user has the assigned roles db_datareader & db_datawriter but it works fine when the db_dbowner but i would rather not have the page user having full access to the database.
