DeleteEntityStoredProcedureAttribute Class

This attribute is used to specify the stored procedure used to delete entities for the associated type

Definition

Namespace: EWSoftware.EntityFramework.DataAnnotations
Assembly: EWSoftware.EntityFramework (in EWSoftware.EntityFramework.dll) Version: 2025.11.12.0
public sealed class DeleteEntityStoredProcedureAttribute : StoredProcedureAttribute
Inheritance
Object    Attribute    StoredProcedureAttribute    DeleteEntityStoredProcedureAttribute

Remarks

The stored procedure must have one or more parameters representing the key columns on the entity type identified with a PrimaryKeyAttribute or one or more properties with a KeyAttribute or defined by the data context. It should not return a value or a result set. All parameters are input only.

Example

C#
[LoadByKeyStoredProcedure("spProductInfo"), InsertEntityStoredProcedure("spProductAddUpdate"),
  UpdateEntityStoredProcedure("spProductAddUpdate"), DeleteEntityStoredProcedure("spProductDelete")]
public sealed class ProductInfo : ChangeTrackingEntity
{
    // The primary key
    [Key]
    public int ProductID
    {
    get;
    set => this.SetWithNotify(value, ref field);
    }

    // Product name
    public string? ProductName
    {
    get;
    set => this.SetWithNotify(value, ref field);
    }

    ...
}

// Example Load By Key usage:
using var dataContext = new DemoDatabaseDataContext();

var productInfo = dc.LoadByKey<ProductInfo>(productID).Single();

// Add a new entity
var newProduct = new ProductInfo { ProductName = "New Product" };

dataContext.InsertEntity(newProduct);

// Update an existing entity
productInfo.ProductName = "Updated Product";

dataContext.UpdateEntity(productInfo);

// Delete an entity
dataContext.DeleteEntity(productInfo);

// Since change tracking is enabled, we could also have just submitted the changes:
// dataContext.SubmitChanges<ProductInfo>();
