此处的值。@RahulSharma患者名称是唯一用于唯一标识患者的列吗？？？在该查询的PARTITION BY子句中，使用用于唯一标识表中患者的所有列。@RahulSharma很高兴它有帮助：）如果您添加“前10至20名患者”和“预订日期为今天”，将获得额外积分按照OP的要求编写代码。您可能希望按date.wt about serialNo=@var？降序排列行号？？它对每个患者都是唯一的…他们没有patientID…@RahulSharma我以为您在那里传递一些变量值，如果不是在那里传递硬编码值的话。@RahulSharma患者名称是唯一用于唯一标识患者的列吗？？？在该查询的PARTITION BY子句中，使用用于唯一标识表中患者的所有列。@RahulSharma很高兴它有帮助：）如果您添加“前10至20名患者”和“预订日期为今天”，将获得额外积分按照OP的要求编写代码。您可能希望按date.wt about serialNo=@var？降序排列行号？？它对每个患者都是唯一的…他们没有patientID…@RahulSharma我以为您在那里传递一些变量值，如果不是在那里传递硬编码值的话。@RahulSharma患者名称是唯一用于唯一标识患者的列吗？？？在该查询的PARTITION BY子句中，使用用于唯一标识表中患者的所有列。@RahulSharma很高兴它有帮助：）
