Question

我正在使用MySqlBulkLoader将文件批量插入到具有外键约束的表中。

using (var conn = new MySqlConnection(connectionString))
{
    var bl = new MySqlBulkLoader(conn);
    bl.TableName = tableName;
    bl.Timeout = 600;
    bl.FieldTerminator = ",";
    bl.LineTerminator = "\r\n";
    bl.FileName = tempFilePath;
    bl.NumberOfLinesToSkip = 1;
    numberOfInsertedRows = bl.Load();
}

文件内容如下所示：

CampaignRunId,RecipientId,IsControlGroup
27,"testrecipient_0",False
27,"testrecipient_1",False
27,"testrecipient_2",False
27,"testrecipient_3",False
27,"testrecipient_4",False
27,"testrecipient_5",False
27,"testrecipient_6",False
27,"testrecipient_7",False
27,"testrecipient_8",False
27,"testrecipient_9",False
27,"testrecipient_10",False
27,"testrecipient_11",False
27,"testrecipient_12",False
27,"testrecipient_13",False

CampaignRunId列是引用另一个表CampaignRun的Id列的FK。 id 27已存在于该表中，当我在MySql Workbench上直接使用单个INSERT查询时，插入成功。但是从我的程序中，这似乎不起作用，我得到以下MySqlException：

无法添加或更新子行：外键约束失败（postbag。campaignrecipient，CONSTRAINT FK_CampaignRecipient_CampaignRun外键（CampaignRunId）参考campaignrun（Id）ON UPETE CASCADE ON UPDATE CASCADE）

我应该在插入之前删除外键并在之后添加它们吗？

MySqlBulkLoader对外键敏感吗？
