Error(1,1): PLS-00410: duplicate fields in RECORD,TABLE or argument list are not permitted

我没有看到任何重复的字段,所以我想知道为什么会发生这种情况(程序如下).另外存储过程似乎只允许查询返回一行,有没有办法让它返回多行？

我看到很多关于返回多行的问题,但没有一行太清楚.我还需要多个存储过程,所以我想知道是否有任何变量和诸如此类的冲突.

  p5_checkartist IN VARCHAR2,p5_artist OUT TESTTABLE.artist%TYPE,p5_thisweekpos OUT TESTTABLE.thisweekpos%TYPE,p5_lastweekpos OUT TESTTABLE.lastweekpos%TYPE,p5_title OUT TESTTABLE.title%TYPE,p5_entrydate OUT TESTTABLE.entrydate%TYPE,p5_entrypos OUT TESTTABLE.entrypos%TYPE,p5_peakpos OUT TESTTABLE.peakpos%TYPE,p5_totalweek OUT TESTTABLE.totalweek%TYPE,p5_thisweekdate OUT TESTTABLE.thisweekdate%TYPE)
