Overloads
| ExecuteSqlRawAsync(DatabaseFacade, String, Object[]) |
Executes the given SQL against the database and returns the number of rows affected. |
| ExecuteSqlRawAsync(DatabaseFacade, String, CancellationToken) |
Executes the given SQL against the database and returns the number of rows affected. |
| ExecuteSqlRawAsync(DatabaseFacade, String, IEnumerable<Object>, CancellationToken) |
Executes the given SQL against the database and returns the number of rows affected. |
ExecuteSqlRawAsync(DatabaseFacade, String, Object[])
Executes the given SQL against the database and returns the number of rows affected.
public static System.Threading.Tasks.Task<int> ExecuteSqlRawAsync (this Microsoft.EntityFrameworkCore.Infrastructure.DatabaseFacade databaseFacade, string sql, params object[] parameters);static member ExecuteSqlRawAsync : Microsoft.EntityFrameworkCore.Infrastructure.DatabaseFacade * string * obj[] -> System.Threading.Tasks.Task<int><Extension()>
Public Function ExecuteSqlRawAsync (databaseFacade As DatabaseFacade, sql As String, ParamArray parameters As Object()) As Task(Of Integer)Parameters
- databaseFacade
- DatabaseFacade
The DatabaseFacade for the context.
- sql
- String
The SQL to execute.
- parameters
- Object[]
Parameters to use with the SQL.
Returns
A task that represents the asynchronous operation. The task result is the number of rows affected.
Remarks
Note that this method does not start a transaction. To use this method with a transaction, first call BeginTransaction(DatabaseFacade, IsolationLevel) or UseTransaction.
Note that the current ExecutionStrategy is not used by this method since the SQL may not be idempotent and does not run in a transaction. An ExecutionStrategy can be used explicitly, making sure to also use a transaction if the SQL is not idempotent.
As with any API that accepts SQL it is important to parameterize any user input to protect against a SQL injection attack. You can include parameter place holders in the SQL query string and then supply parameter values as additional arguments. Any parameter values you supply will automatically be converted to a DbParameter.
However, never pass a concatenated or interpolated string ($"") with non-validated user-provided values into this method. Doing so may expose your application to SQL injection attacks. To use the interpolated string syntax, consider using ExecuteSqlAsync(DatabaseFacade, FormattableString, CancellationToken) to create parameters.

Public Function ExecuteSqlRawAsync (databaseFacade As DatabaseFacade, sql As String, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Integer)Parameters
- databaseFacade
- DatabaseFacade
The DatabaseFacade for the context.
- sql
- String
The SQL to execute.
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for the task to complete.
Returns
A task that represents the asynchronous operation. The task result is the number of rows affected.
Exceptions
If the CancellationToken is canceled.
