如何检查没有返回值的存储过程是否已执行？

Question

我正在执行一个没有返回值的存储过程.如何检查它是否已被执行？这是代码:

this.dbProviderFactory = DalFactory.GetFactory(this.adapterConfiguration);
DbConnection dbConnection = dbProviderFactory.CreateConnection();

dbConnection.ConnectionString = this.adapterConfiguration.DatabaseInformation.ExternalDatabaseInformation.connectionString;
dbConnection.Open();

DbCommand cmd = dbConnection.CreateCommand();
cmd.CommandText = "h_AS_SP_ResetUnfinishedJobs";
cmd.CommandType = CommandType.StoredProcedure;
cmd.ExecuteNonQuery();

这是存储过程:

ALTER PROCEDURE [dbo].[h_AS_SP_ResetUnfinishedJobs]
AS
BEGIN
 -- Delete all unfinished jobs where the force flag has not been set...
 DELETE FROM h_AS_mds_MetaDataStatus
 WHERE mds_status NOT IN (11,12) AND mds_force = 0
END

Answer 1

使用时,存储过程将返回"受影响的行数" ExecuteNonQuery():

DbCommand cmd = dbConnection.CreateCommand();
cmd.CommandText = "h_AS_SP_ResetUnfinishedJobs";
cmd.CommandType = CommandType.StoredProcedure;
int rowsAffected = cmd.ExecuteNonQuery();

这将让您了解是否有任何事情已经完成.但是:如果不影响任何行也是存储过程的有效结果,则无法真正使用该返回值来检查它是否已运行.

除此之外:除非发生异常,否则电话大概有效!
