Question

我需要为下面的表创建聚簇索引和非聚簇索引。当我尝试为临时表创建索引时，它的工作正常。当我尝试为此表创建索引时，它会抛出语法错误。

DECLARE @SearchReviseBudget TABLE(           
    id                 INT IDENTITY(1, 1),           
    fundid             BIGINT,           
    programid          BIGINT ,          
    projectid          BIGINT,           
    applicationnumber  VARCHAR(50),           
    applicationname    VARCHAR(100),           
    startdate          DATETIME,           
    enddate            DATETIME,           
    programtypeidfkid  VARCHAR(50),           
    applicationbudget  MONEY,

    [Left]             MONEY,

您可以隐式地创建表变量的索引，作为唯一约束的一部分。

下面将创建与其他答案完全相同的索引（除了CI被声明为唯一的，在那里省略）。虽然看起来好像UNIQUE(fundid, startdate,id)包含了该答案中第二个索引中不存在的附加键列，但它将隐式包含在那里，因为聚簇索引键包含在所有非唯一非聚簇索引的键级别

DECLARE @SearchReviseBudget TABLE(           
    id                 INT IDENTITY(1, 1) PRIMARY KEY,           
    fundid             BIGINT,           
    programid          BIGINT ,          
    projectid          BIGINT,           
    applicationnumber  VARCHAR(50),           
    applicationname    VARCHAR(100),           
    startdate          DATETIME,           
    enddate            DATETIME,           
    programtypeidfkid  VARCHAR(50),           
    applicationbudget  MONEY,           
    utlized            MONEY ,       
    [Left]             MONEY,           
    companyname        VARCHAR(100),           
    multiyearbudgetid  BIGINT,           
    totalprogrambudget MONEY ,
    UNIQUE(fundid, startdate,id)
    )

除了总行数之外，表变量没有为它们维护统计数据（并且你需要使用OPTION (RECOMPILE)）所以#temp表通常是更好的选择。< / p>
