ORA-00918错误是Oracle数据库中的一个常见错误,其完整错误信息为“column ambiguously defined”,意为“列定义不明确”。这个错误通常发生在执行SQL查询时,当查询中的SELECT子句、ORDER BY子句、GROUP BY子句或其他相关子句中引用了多个表中具有相同名称的列,而查询又没有明确指出要引用哪个表的列时,就会触发此错误。
当两表联合查询,选择的列在两表都存在时,就会出现此错,如: SQL>selectid2fromemp a,dept b3wherea.deptid=b.id;selectid*第1行出现错误: ORA-00918: 未明确定义列 以上SQL中,由于id在两表都存在,故而出错。 END
