怎么了？如何解决？
相关提示是错误信息Invalid column name '343'。在
# WRONG, column names instead of string constants
" ... VALUES (\"343\", \"565\", \"343\", \"343\")"
您正在使用双引号分隔字符串。 Oracle SQL 中的字符串必须放在单引号中。双引号用于转义列名和其他标识符。
# CORRECT
" ... VALUES ('343', '565', '343', '343')"
如果相应的列是文本类型，这将解决该问题。对于数字类型的列，不要使用引号。例如。如果第一列 mst 是数字，写：
" ... VALUES (343, '565', '343', '343')"
请注意，您可以在值子句中使用列名或表达式。仅仅因为它出现在 VALUES 子句中并不意味着它必须是常量或文字。参见：VALUES expression
