| ExecuteStoreCommand(String, Object[]) |
Executes an arbitrary command directly against the data source using the existing connection. The command is specified using the server's native query language, such as SQL. 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. context.ExecuteStoreCommand("UPDATE dbo.Posts SET Rating = 5 WHERE Author = @p0", userSuppliedAuthor); Alternatively, you can also construct a DbParameter and supply it to SqlQuery. This allows you to use named parameters in the SQL query string. context.ExecuteStoreCommand("UPDATE dbo.Posts SET Rating = 5 WHERE Author = @author", new SqlParameter("@author", userSuppliedAuthor)); |
