我运行脚本，从表中选择：

SELECT *
FROM [Portfolios]
where Delisted = 0 
  and BrokerAccountId is not null 
  and ImportType = 2
GO

表的脚本：

CREATE TABLE [dbo].[Portfolios](
    [PortfolioId] [int] IDENTITY(1,1) NOT NULL,
    [UserId] [int] NOT NULL,
    [Guid] [uniqueidentifier] ROWGUIDCOL  NOT NULL,
    [Name] [nvarchar](255) NOT NULL,
    [Notes] [nvarchar](max) NULL,
    [IsDefault] [bit] NOT NULL,
    [Cash] [money] NOT NULL,
    [CurrentCash] [money] NULL,
    [Type] [int] NULL,
    [Delisted] [bit] NOT NULL,
    [CurrencyId] [int] NOT NULL,
    [TrackCashBalanceType] [int] NULL,
    [IsDividendReinvestment] [bit] NOT NULL,
    [ItemId] [int] NULL,
    [FinancialInstitutionId] [int] NULL,
    [Configured] [bit] NULL,
    [BrokerAccountId] [int] NULL,
    [ImportType] [int] NULL,
    [PortfolioTotalValue] [money] NULL,
    [IsRequireNewCredentials] [bit] NOT NULL,
 CONSTRAINT [Portfolios_PK] PRIMARY KEY CLUSTERED 
(
    [PortfolioId] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY],
 CONSTRAINT [Portfolios_uq] UNIQUE NONCLUSTERED 
(
    [Guid] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

通常，此脚本执行大约 10 秒。但是现在它没有完成，但是当我取消在 SQL Server 中执行查询时，所有需要的数据都被读取。

任何想法为什么查询没有完成？

检查桌子上的锁，

试试下面的查询

SELECT * FROM [TradeStops3].[dbo].[Portfolios]/*(NOLOCK) 使用此 */ 其中 Delisted = 0 且 BrokerAccountId 不为空且 ImportType = 2 GO

如果没有帮助，请更新。

问候
