SQLite3，MATCH和OR

Question

将MATCH与OR结合使用是否有效？

例如，

SELECT * FROM myTable WHERE name MATCH 'andrew' OR name MATCH 'bill';

不会产生任何命中，而两者都

SELECT * FROM myTable WHERE name MATCH 'andrew';和

SELECT * FROM myTable WHERE name MATCH 'bill';

确实给予点击。

编辑。带有OR错误代码的选择是1，所以它有些不正确。第二个和第三个的结果是0所以它们很好。我不确定是什么问题。

Answer 1

http://www.sqlite.org/fts3.html#section_3

SELECT * FROM myTable WHERE name MATCH 'andrew OR bill'

Answer 2

SELECT * FROM myTable WHERE name MATCH 'andrew OR bill'

SELECT * FROM myTable WHERE name MATCH ('andrew' OR 'bill')

c.execute("SELECT * FROM myTable WHERE name MATCH (? OR ?)", ('andrew', 'bill'))
#safe from SQL injection attacks by escaping the variables.

  

SQLite了解以下二元运算符，   从最高优先级到最低优先级：

||
*    /    %
+    -
<<   >>   &    |
<    <=   >    >=
=    ==   !=   <>   IS   IS NOT   IN   LIKE   GLOB   MATCH   REGEXP
AND

OR

     

支持的一元前缀运算符如下：

-    +    ~    NOT
