Question

oracle sqlcode=-911是什么错误，可能是 什么原因造成的

Answer 1

911是无效字符，你的语句里面的字符不对吧

Answer 2

oerr ora 911
00911, 00000, "invalid character"
// *Cause: identifiers may not start with any ASCII character other than
// letters and numbers. $#_ are also allowed after the first
// character. Identifiers enclosed by doublequotes may contain
// any character other than a doublequote. Alternative quotes
// (q'#...#') cannot use spaces, tabs, or carriage returns as
// delimiters. For all other contexts, consult the SQL Language
// Reference Manual.
// *Action:

标识符不合法。修改标识符的名称。
