如何使用单引号将查询插入mysql

Question

我想将查询插入到数据库中，该数据库中包含单引号。我怎么能在PHP中处理这个？

我的查询是：

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'A'', 'in queue', ' (Scheduled Query #413) Pull all items where National Status C' at line 1

它显示错误

{{1}}

Answer 1

将单引号（＆＃39;）的值替换为 BackSlash＆amp;单引号（\＆＃39;）或两个单引号（＆＃39;＆＃39;）

试试这个：

opacity = 0.1

或

INSERT INTO QUERY (date_time, userid, user_traits, query_sql, STATUS, description, is_scheduled_row) 
VALUES ('2016-01-06 02:39:01', '307', '0,3598,1937,13891,37746,22082,2596,2431,12850,3917,1234784,44712,14638,14418,12850,2631,25003,11428,27450,2592,23593,11441,2826,36330,32219,32351,20720,13997,2594,2467,15687', 'Select * from gl_base_schema.item where national_status_cd = ''A''', 'in queue', ' (Scheduled Query #413) Pull all items where National Status Code is ''A''', 1);

Answer 2

$query = "Select * from gl_base_schema.item where national_status_cd = 'A'";
$sql = "insert into query (date_time, userid, user_traits, query_sql, status, description, is_scheduled_row) values ('2016-01-06 02:39:01', '307', '0,3598,1937,13891,37746,22082,2596,2431,12850,3917,1234784,44712,14638,14418,12850,2631,25003,11428,27450,2592,23593,11441,2826,36330,32219,32351,20720,13997,2594,2467,15687', '."'".$query."'".', 'in queue', ' (Scheduled Query #413) Pull all items where National Status Code is \'A\'', 1)";

Answer 3

你可以使用 double 和单引号组合：

'A'

您可以将"'A' test"此字符串用于另一个字符串，而不能将其用作grid.addView(newMonster);

Answer 4

如果您有'A''，请将其设为'A'''。额外的'会转义下一个'，因此您需要''一个'。希望有所帮助。
