ExecuteNonQueryAsync(IEnumerable<MigrationCommand>, IRelationalConnection, CancellationToken)

Source:

IMigrationCommandExecutor.cs

使用给定的数据库连接执行给定命令。

public System.Threading.Tasks.Task ExecuteNonQueryAsync(System.Collections.Generic.IEnumerable<Microsoft.EntityFrameworkCore.Migrations.MigrationCommand> migrationCommands, Microsoft.EntityFrameworkCore.Storage.IRelationalConnection connection, System.Threading.CancellationToken cancellationToken = default);

abstract member ExecuteNonQueryAsync : seq<Microsoft.EntityFrameworkCore.Migrations.MigrationCommand> * Microsoft.EntityFrameworkCore.Storage.IRelationalConnection * System.Threading.CancellationToken -> System.Threading.Tasks.Task

Public Function ExecuteNonQueryAsync (migrationCommands As IEnumerable(Of MigrationCommand), connection As IRelationalConnection, Optional cancellationToken As CancellationToken = Nothing) As Task

参数

migrationCommands

IEnumerable<MigrationCommand>

要执行的命令。

connection

IRelationalConnection

要使用的连接。

cancellationToken

CancellationToken

等待任务完成时观察的 A CancellationToken 。

返回

Task

表示异步操作的任务。

例外

OperationCanceledException

如果取消了该操作 CancellationToken 。

ExecuteNonQueryAsync(IReadOnlyList<MigrationCommand>, IRelationalConnection, MigrationExecutionState, Boolean, Nullable<IsolationLevel>, CancellationToken)

Source:

IMigrationCommandExecutor.cs

使用给定的数据库连接执行给定命令。

public System.Threading.Tasks.Task<int> ExecuteNonQueryAsync(System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Migrations.MigrationCommand> migrationCommands, Microsoft.EntityFrameworkCore.Storage.IRelationalConnection connection, Microsoft.EntityFrameworkCore.Migrations.MigrationExecutionState executionState, bool commitTransaction, System.Data.IsolationLevel? isolationLevel = default, System.Threading.CancellationToken cancellationToken = default);

abstract member ExecuteNonQueryAsync : System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Migrations.MigrationCommand> * Microsoft.EntityFrameworkCore.Storage.IRelationalConnection * Microsoft.EntityFrameworkCore.Migrations.MigrationExecutionState * bool * Nullable<System.Data.IsolationLevel> * System.Threading.CancellationToken -> System.Threading.Tasks.Task<int>

参数

migrationCommands

IReadOnlyList<MigrationCommand>

要执行的命令。

connection

IRelationalConnection

要使用的连接。

executionState

MigrationExecutionState

当前迁移执行的状态。

commitTransaction

Boolean

指示是否应提交此调用启动的事务。 如果 false，事务将可用 executionState。

isolationLevel

Nullable<IsolationLevel>

事务的隔离级别。

cancellationToken

CancellationToken

等待任务完成时观察的 A CancellationToken 。

返回

Task<Int32>

表示异步操作的任务。

例外

OperationCanceledException

如果取消了该操作 CancellationToken 。
