Properties

CommandText	Gets the command text to be executed.
Parameters	Gets the parameters for the command.

Methods

CreateDbCommand(RelationalCommandParameterObject, Guid, DbCommandMethod)	Called by the execute methods to create a DbCommand for the given DbConnection and configure timeouts and transactions. This method is typically used by database providers (and other extensions). It is generally not used in application code.
ExecuteNonQuery(IRelationalConnection, IReadOnlyDictionary<String,Object>, Boolean)	Obsolete. Executes the command with no results.
ExecuteNonQuery(IRelationalConnection, IReadOnlyDictionary<String,Object>)	Executes the command with no results.
ExecuteNonQuery(RelationalCommandParameterObject)	Executes the command with no results.
ExecuteNonQueryAsync(IRelationalConnection, IReadOnlyDictionary<String,Object>, Boolean, CancellationToken)	Obsolete. Asynchronously executes the command with no results.
ExecuteNonQueryAsync(IRelationalConnection, IReadOnlyDictionary<String,Object>, CancellationToken)	Asynchronously executes the command with no results.
ExecuteNonQueryAsync(RelationalCommandParameterObject, CancellationToken)	Asynchronously executes the command with no results.
ExecuteReader(IRelationalConnection, IReadOnlyDictionary<String,Object>, Boolean)	Obsolete. Executes the command with a RelationalDataReader result.
ExecuteReader(IRelationalConnection, IReadOnlyDictionary<String,Object>)	Executes the command with a RelationalDataReader result.
ExecuteReader(RelationalCommandParameterObject)	Executes the command with a RelationalDataReader result.
ExecuteReaderAsync(IRelationalConnection, IReadOnlyDictionary<String,Object>, Boolean, CancellationToken)	Obsolete. Asynchronously executes the command with a RelationalDataReader result.
ExecuteReaderAsync(IRelationalConnection, IReadOnlyDictionary<String,Object>, CancellationToken)	Asynchronously executes the command with a RelationalDataReader result.
ExecuteReaderAsync(RelationalCommandParameterObject, CancellationToken)	Asynchronously executes the command with a RelationalDataReader result.
ExecuteScalar(IRelationalConnection, IReadOnlyDictionary<String,Object>, Boolean)	Obsolete. Executes the command with a single scalar result.
ExecuteScalar(IRelationalConnection, IReadOnlyDictionary<String,Object>)	Executes the command with a single scalar result.
ExecuteScalar(RelationalCommandParameterObject)	Executes the command with a single scalar result.
ExecuteScalarAsync(IRelationalConnection, IReadOnlyDictionary<String,Object>, Boolean, CancellationToken)	Obsolete. Asynchronously executes the command with a single scalar result.
ExecuteScalarAsync(IRelationalConnection, IReadOnlyDictionary<String,Object>, CancellationToken)	Asynchronously executes the command with a single scalar result.
ExecuteScalarAsync(RelationalCommandParameterObject, CancellationToken)	Asynchronously executes the command with a single scalar result.
PopulateFrom(IRelationalCommandTemplate)	Populates this command from the provided `commandTemplate`.

Extension Methods

ExecuteNonQuery(IRelationalCommand, IRelationalConnection)	Executes the command with no results.
ExecuteNonQueryAsync(IRelationalCommand, IRelationalConnection, CancellationToken)	Asynchronously executes the command with no results.
ExecuteReader(IRelationalCommand, IRelationalConnection)	Executes the command with a RelationalDataReader result.
ExecuteReaderAsync(IRelationalCommand, IRelationalConnection, CancellationToken)	Asynchronously executes the command with a RelationalDataReader result.
ExecuteScalar(IRelationalCommand, IRelationalConnection)	Executes the command with a single scalar result.
ExecuteScalarAsync(IRelationalCommand, IRelationalConnection, CancellationToken)	Asynchronously executes the command with a single scalar result.
