如何在存儲過程中使用單引號傳遞輸入參數

Question

我有一個存儲過程 r，我正在傳遞下面的字符串，但它不起作用？？

call Prc_SearchKeyword('randomize', "'girl', 'playing'",2,0,31);

下面的語法工作正常..

call Prc_SearchKeyword('randomize', 'girl',1,0,31);



DELIMITER $$

CREATE PROCEDURE `Prc_SearchKeyword`(IN filter VARCHAR(50), IN midquery varchar(200), IN keywordcount int(10), In firstimage int(10), in lastimage int(10) )
BEGIN
IF(filter = 'nbofviews') Then
SELECT sd.imageid, sd.imgcollection, sd.Caption FROM   (SELECT p.imageid  FROM searchinitial_views p join searchkwdmgmt s on p.primarykeyword = s.primary_kwd and s.allkwd in (midquery) GROUP  BY p.imageid HAVING Count(distinct p.primarykeyword) = keywordcount order by views desc  LIMIT  firstimage, lastimage ) q join searchdetails sd ON sd.imageid = q.imageid ;
END IF;
IF(filter = 'shootdate') Then
SELECT sd.imageid, sd.imgcollection, sd.Caption FROM   (SELECT p.imageid  FROM searchinitial_shootdate p join searchkwdmgmt s on p.primarykeyword = s.primary_kwd and s.allkwd in (midquery) GROUP  BY p.imageid HAVING Count(distinct p.primarykeyword) = keywordcount order by shootdate desc  LIMIT  firstimage, lastimage ) q join searchdetails sd ON sd.imageid = q.imageid ;

Answer 1

您需要查找如何轉義字符，即使用兩個單引號而不是一個''girl'',''playing''

Answer 2

您可以使用兩個單引號轉義單引號：例如：

... where lastname='O''Malley'

在你的情況下：

''girl'',''playing''

Answer 3

由於 MySQL 將單引號和雙引號都識別為字符串分隔符，因此一種選擇是在值中包含單引號時使用雙引號，反之亦然。

call YourProc("'girl', 'playing'");

另一種方法是用反斜杠轉義引號：

call YourProc('\'girl\', \'playing\'');
