Sql 使用视图时减少运行时构造查询的执行时间
我使用了一个查询，我只知道在运行时检索哪些变量。我使用一个视图将所有变量拉入一个数据集中，然后对该数据集进行查询。它看起来像这样：Sql 使用视图时减少运行时构造查询的执行时间,sql,sql-server,Sql,Sql Server,我使用了一个查询，我只知道在运行时检索哪些变量。我使用一个视图将所有变量拉入一个数据集中，然后对该数据集进行查询。它看起来像这样： All variables in the SQL db: Table A.1, Table A.2, Table A.3 Table B.1, Table B.2, Table B.3 Table C.1, Table C.2, Table C.3 在运行时，我知道我需要变量表A.1和表A.2，其中表A.1=SomeNumber。因此，我创建了一个视图： 视图1=
