When the CommandType property is set to StoredProcedure, the CommandText property should be set to the name of the stored procedure. SqlClient adds support for SQL Server Express LocalDB connectivity that can be used by a developer. WebThe following example creates a SqlCommand and then executes it using ExecuteScalar. Prerequisites. The runtime recognizes that classes derived from MarshalByRefObject should be marshaled across app domain boundaries. Objects in different application domains communicate either by transporting copies of objects across application domain boundaries, or by using a proxy to exchange messages. The Stream, XmlReader or TextReader object was closed during a streaming operation. Example 1. #tool nuget:?package=System.Data.SqlClient&version=4.8.5, Portable Class Library (Portable Class Library, Windows 8.1, WindowsPhoneApp 8.1).

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The overload of Add that takes a string and an object was deprecated because of possible ambiguity with the SqlParameterCollection.Add overload that takes a String and a SqlDbType enumeration value where passing an integer with the string could be interpreted as being either the parameter value or the corresponding SqlDbType value. Returns a string that represents the current object. A timeout occurred during a streaming operation. When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of rows affected by the trigger or triggers. Initializes a new instance of the SqlParameter class that uses the parameter name, the SqlDbType, the size, and the source column name. Types must inherit from MarshalByRefObject when the type is used across application domain boundaries, and the state of the object must not be copied because the members of the object are not usable outside the application domain where they were created. Microsoft 2022 -
