所以我现在有这个
SET @title = (SELECT title FROM fnBorrowerBooks(@name, 'G3'))
SET @dateBorrowed = (SELECT DateBorrowed FROM fnBorrowerBooks(@name, 'G3'))
SET @dateReturned = (SELECT DateReturned FROM fnBorrowerBooks(@name, 'G3'))
但基本上我需要的是像
SET @variable 1 = (SELECT * FROM fnBorrowerBooks(@name, @Genre)
但是这会返回3列并且CAN返回多个ROWS,这显然不会起作用,因为你不能分配多个值,我需要打印我得到多少结果所以如果我得到3个不同的结果我需要打印所有3如果有意义那么在1字符串中
PRINT CONCAT(@ variable1,'ble ble ble')应该返回多行,具体取决于有多少结果,而我无法找到如何实现此目的的方法。

如果您只需要标题,那么您可以在查询中连接:
<application
android:label="@string/your_app_name"
>
....

您可以尝试使用临时表和循环,如下所示:
CREATE TABLE #t
(tKey int IDENTITY(1,1) PRIMARY KEY,
Column1 varchar(100),
Column2 varchar(100),
...)
INSERT INTO #t
SELECT * --the columns you select here need to be in the column list above
FROM fnBorrowerBooks(@name, @Genre)
DECLARE @Count int
DECLARE @MyString varchar(max)
SET @Count = 1
SET @MyString = ''
WHILE @Count <= (SELECT MAX(Key) FROM #t)
BEGIN
SET @MyString += (SELECT Column1 + ', ' + Column2 + ... FROM #t WHERE tKey = @Count)
SET @Count += 1
END
PRINT(@MyString)
