sql - 在 SQL 中声明多个表变量时出错

Question

我在 Microsoft SQL Server 中声明多表变量时遇到问题。试图用逗号分隔表格，但似乎给了我一些语法错误。

代码看起来像这样。将代码显示为示例和图片，以便您查看错误标记:

DECLARE
@StructuredProducts TABLE(
    StructuredProductId INT
    ,ArrangerIdv2 INT
    ,ISIN VARCHAR(50)
    ,InstrumentId INT
    ,Caption VARCHAR(100)
    ,DbRegDate DATE
    ,EndDate DATE
),
@PriceDataOld TABLE(
    StructuredProductId INT
    ,FinalDate DATE
    ,FinalPriceDate DATE
    ,FinalPrice DECIMAL(9,3)
    ,FinalPriceSek DECIMAL(9,3)
),
@PriceDataEarlyExercise TABLE(
    StructuredProductId INT
    ,EEDate DATE
    ,EEPriceDate DATE
    ,EEPrice DECIMAL(9,3)
    ,EEPriceSek DECIMAL(9,3)
),
@PriceDataActive TABLE(
    StructuredProductId INT
    ,ActiveDate DATE
    ,ActivePriceDate DATE
    ,ActivePrice DECIMAL(9,3)
    ,ActivePriceSek DECIMAL(9,3)
)

Isn't comma the way to declare multiple variables?

好吧，是的，逗号可用于声明多个局部变量和游标，但是 不是 表变量 - docs明确地说:

n

Is a placeholder indicating that multiple variables can be specified and assigned values. When declaring table variables, the table variable must be the only variable being declared in the DECLARE statement.
