我得到的结果是:ALTER TABLE AO_21F425_MESSAGE_MAPPING_AO MODIFY USER_HASH varchar CHARACTER SET UTF8 COLLATE_bin NOT NULL;
ALTER TABLE AO_38321B_CUSTOM_CONTENT_LINK MODIFY LINK_URL
为什么MySQL会返回# MySQL returned an empty result set (i.e. zero rows).和3 row(s) affected.?我的SQL语句中有什么错误吗?mediumint(8) unsigned NOT NULL AUTO_INCREMENT, `url` varchar(70) COLLATEutf8_unicode_ci NOT NULL,
`title` varchar(70) COLLA
我需要在存储过程中的准备语句中指定排序规则,例如<col> LIKE ? COLLATE utf8_unicode_ci。COLLATE utf8_unicode_ci、LIKE CONVERT(? AS utf8) COLLATE utf8_unicode_ci和LIKE CAST(?AS varchar CHARACTER SET utf8) COLLATE utf8_unicode_ci,但错误如下:
