从MySQL 5.7.6版本开始,如果启用了NO_BACKSLASH_ESCAPES, 则mysql_real_escape_string()函数失败,错误码为CR_INSECURE_API_ERR, 这个时候应当使用mysql_real_escape_string_quote()替代mysql_real_escape_string()。 启用NO_BACKSLASH_ESCAPES,表示将反斜杠当作普通字符,而不是转义字符: SET sql_mode='NO_BACKSLASH...
在Python和MySQL中使用LIKE时出现警告1292是因为MySQL的默认配置中启用了NO_BACKSLASH_ESCAPES模式。在该模式下,反斜杠(\)被视为普通字符,而不是转义字符。因此,当使用LIKE语句时,如果模式中包含反斜杠,MySQL会发出警告。 要解决这个问题,有两种方法: 方法一:在MySQL连接之前,设置SQL_MODE为NO_BACKSLASH_ESCAPES模...
NO_BACKSLASH_ESCAPES:(禁用反斜线转义)这个模式启用,反斜线将会变成一个普通的字符串。 NO_DIR_IN_CREATE:在创建表时忽略所有的index directory和data directory选项。 NO_ENGINE_SUBSTITUTION: 此模式指定当执行create语句或者alter语句指定的存储引擎没有启用或者没有编译时,控制默认默认存储引擎的自动切换。默认是启用...
NO_BACKSLASH_ESCAPES 当NO_BACKSLASH_ESCAPES被启用时,MySQL会禁用反斜杠(\)作为转义字符的功能,这也会导致下划线失效。 SETsql_mode='NO_BACKSLASH_ESCAPES'; 1. 在这种情况下,我们可以使用反斜杠来转义下划线,以便正确匹配。例如,我们可以使用LIKE 'a\\_b'来匹配"a_b"。

(11)NO_BACKSLASH_ESCAPES:该选项决定反斜杠\的作用;启用后,反斜杠\不再作为转义字符,而是用作普通字符。 (12)NO_DIR_IN_CREATE:该选项决定忽略创建表时,所有的INDEX DIRECTORY和DATA DIRECTORY指令;该选项只在从库生效。 (13)NO_ENGINE_SUBSTITUTION:该选项决定创建表时,如果指定一个不存在/不支持的存储引擎,那...
As far as I understand from the documentation the NO_BACKSLASH_ESCAPES should fix this behaviour - it does not in all cases. e.g. when issuing the query from mySQL query browser. hope that explains better the problem cheers brian Sorry, you can't reply to this topic. It has been closed...
