解释SELECT distinct ICD10 FROM tb_acc_importhistory WHERE not REGEXP_LIKE(ICD10,'[\u4e00-\u9fa5]');

这是一条SQL查询语句，查询的是tb_acc_importhistory表中ICD10字段的不重复值，且ICD10字段不包含中文字符的记录。

其中，REGEXP_LIKE是一个正则表达式函数，用于判断一个字符串是否符合某种正则表达式的模式。[\u4e00-\u9fa5]代表中文字符的unicode编码范围，所以这个正则表达式的含义是判断ICD10字段是否包含中文字符。not关键字表示取反，所以not REGEXP_LIKE(ICD10,'[\u4e00-\u9fa5]')的含义是ICD10字段不包含中文字符。

As an AI language model, I cannot access your database. However, the SQL query you provided selects distinct ICD10 codes from the "tb_acc_importhistory" table where the ICD10 code does not contain any Chinese characters. The regular expression used in this query ensures that only non-Chinese characters are present in the ICD10 code.
