集成全文搜索与 Transact-SQL 谓词
CONTAINS 和 FREETEXT 谓词可以与其他任一 Transact-SQL 谓词(如 LIKE 和 BETWEEN)相结合,它们还可用于子查询中。以下示例将搜索 ID 不等于 5 并且包含词“aluminum”和“spindle”的说明。
USE AdventureWorks;
GO
SELECT Description
FROM Production.ProductDescription
WHERE ProductDescriptionID <> 5 AND
CONTAINS(Description, ' Aluminum AND spindle');
GO
以下查询在子查询中使用了 CONTAINS。此查询将使用 AdventureWorks 数据库获取 ProductReview 表中针对某一特定循环的所有注释的注释值。
USE AdventureWorks;
GO
INSERT INTO Production.ProductReview
(ProductID, ReviewerName, EmailAddress, Rating, Comments)
VALUES
(780, 'John Smith', 'john@fourthcoffee.com', 5,
'The Mountain-200 Silver from AdventureWorks Cycles meets and exceeds expectations. I enjoyed the smooth ride down the roads of Redmond')

WAITFOR DELAY '00:00:30'
-- Wait 30 seconds to make sure that the full-text index gets updated.
SELECT r.Comments, p.Name
FROM Production.ProductReview r
JOIN Production.Product p
ON
r.ProductID = p.ProductID
AND r.ProductID = (SELECT ProductID
FROM Production.ProductReview
WHERE CONTAINS (Comments,
' AdventureWorks AND
Redmond AND
"Mountain-200 Silver" '))
GO
