MySQL Error number: 4149; Symbol: ER_BULK_PARSER_UNEXPECTED_CHAR_AFTER_NULL_ESCAPE; SQLSTATE: HY000

文档解释

以内

Error number:4149; Symbol: ER_BULK_PARSER_UNEXPECTED_CHAR_AFTER_NULL_ESCAPE; SQLSTATE:HY000

错误说明:

ER_BULK_PARSER_UNEXPECTED_CHAR_AFTER_NULL_ESCAPE 又称为Null Escape字符之后意外字符,这是MySQL中定义的一个SQL安全错误,只出现在批量导入任务(BULK IMPORT)时。此错误指示,在当前使用 \\N 字符后,应该是一个分隔字符,但却出现了其他无效字符。

常见案例:

此错误通常出现在处理大量CSV文件(Comma-Separated Value)或其他类型的文本文件时,可能的案例是:用户将文件作为一个单元进行文本分析时,出现了一些空白字符,导致 “Null Escape 字符” 之后出现意外字符,从而导致出现这个错误。

解决方法:

此错误指示着用户当前正在处理的文本文件中,NULL Escape字符(\\N)后出现了错误字符,需要将代替\\N之后错误字符,然后重试批量导入任务。为了更好的调试此问题,用户应该在错误信息中查找原始文档行和列,并查看在那里出现了错误字符。最后,确保在批量导入任务之前,仔细检查原始文档,确保其中没有NULL Escape字符之后的错误字符。
