Stored procedures ORA-00936错误：插入查询在过程中不起作用

它显示的是ORA-00936:Oracle11g中缺少表达式错误

试一试

像这样使用

execute immediate 'insert into ' || rec.destinationtable || '(' || rec.destinationcolumn || ',' || rec.destinationcolumn1 || ') values ( (select ' || rec.sourcecolumn || ' from ' || rec.sourcetable||' ),(select ' || rec.sourcecolumn || ' from ' || rec.sourcetable||'))';

如果指定要插入的cloumn名称，请在查询中省略“values”短语

execute immediate 'insert into ' || rec.destinationtable ||
'(' || rec.destinationcolumn || ',' || rec.destinationcolumn1 || ')
( select ' || rec.sourcecolumn || ' from ' || rec.sourcetable||' ,
select ' || rec.sourcecolumn || ' from ' || rec.sourcetable||')';

如果执行上述表达式，则会得到如下结果：

     'insert into '
  || rec.destinationtable
  || '(' || rec.destinationcolumn
  || ',' || rec.destinationcolumn1
  || ') values ( select '
  || rec.sourcecolumn
  || ' from '
  || rec.sourcetable
  || ' ,select '
  || rec.sourcecolumn
  || ' from '
  || rec.sourcetable || ')';

这不是有效的insert语句

您正在使用VALUES子句并提供两个表达式，但这些表达式本身就是子查询，因此需要用括号括起来，例如：

insert into [destinationtable]
  ([destinationcolumn]
  ,[destinationcolumn1]
  )
values (
  select [sourcecolumn] from [sourcetable]
 ,select [sourcecolumn] from [sourcetable]
)

因此，您需要在表达式中包含它们，例如：

insert into [destinationtable]
  ([destinationcolumn]
  ,[destinationcolumn1]
  )
values (
   ( select [sourcecolumn] from [sourcetable] )
 , ( select [sourcecolumn] from [sourcetable] )
)

要使代码更加清晰，可以执行以下操作：

  execute immediate
    'insert into '
  || rec.destinationtable
  || '(' || rec.destinationcolumn
  || ',' || rec.destinationcolumn1
  || ') values ( ( select '
  || rec.sourcecolumn
  || ' from '
  || rec.sourcetable
  || ' ) , ( select '
  || rec.sourcecolumn
  || ' from '
  || rec.sourcetable || ' ) )';

经过深思熟虑，我已经取消了否决票。但是，您的答案并不完全正确-子查询select x from y，select z from a将不起作用。

  execute immediate
    'insert into '
  || rec.destinationtable
  || '(' || rec.destinationcolumn
  || ',' || rec.destinationcolumn1
  || ') values ( ( select '
  || rec.sourcecolumn
  || ' from '
  || rec.sourcetable
  || ' ) , ( select '
  || rec.sourcecolumn
  || ' from '
  || rec.sourcetable || ' ) )';

DECLARE
  source1 VARCHAR2(1000);
  source2 VARCHAR2(1000);
BEGIN

  source1 := 'select ' || rec.sourcecolumn || ' from ' || rec.sourcetable;

  source2 := 'select ' || rec.sourcecolumn || ' from ' || rec.sourcetable;

  execute immediate
    'insert into ' || rec.destinationtable
  ||   '(' || rec.destinationcolumn
  ||   ',' || rec.destinationcolumn1
  || ') values ('
  ||   '(' || source1 || ')'
  || ', (' || source2 || ')'
  || ')';

END;
