Question

如何在Dynamic SQL中编写查询，我收到的错误如下所示。

 EXECUTE IMMEDIATE 
 'CREATE TABLE SAMPLE
  SELECT EXTRACT (VALUE (d), '''//row/text()''').getstringval () 
  FROM (SELECT XMLTYPE (   '''<rows><row>'''
  || REPLACE ('''venkat,vijay,bylla,12''', ''',''', '''</row><row>''')
   || '''</row></rows>'''
    ) AS xmlval
     FROM DUAL) x,
   TABLE (XMLSEQUENCE (EXTRACT (x.xmlval, '''/rows/row'''))) d';

错误是：

Error(118,34): PLS-00103: Encountered the symbol "/" when expecting
one of the following:     ( - + case mod new null <an identifier>    
<a double-quoted delimited-identifier> <a bind variable>

您的报价错误，您需要为列添加别名..eg：

SQL> begin
  2  EXECUTE IMMEDIATE
  3   'CREATE TABLE SAMPLE AS
  4    SELECT EXTRACT (VALUE (d), ''//row/text()'').getstringval () a
  5    FROM (SELECT XMLTYPE (   ''<rows><row>''
  6    || REPLACE (''venkat,vijay,bylla,12'', '','', ''</row><row>'')
  7     || ''</row></rows>''
  8      ) AS xmlval
  9       FROM DUAL) x,
 10     TABLE (XMLSEQUENCE (EXTRACT (x.xmlval, ''/rows/row''))) d';
 11  end;
 12  /

PL/SQL procedure successfully completed.

SQL> select * from sample;

A
--------------------------------------------------------------------------------
venkat
vijay
bylla
12

但是你为什么要在oracle中动态创建表？如果你正在考虑在你的代码中动态创建表，这是不好的做法，在oracle中要避免使用（如果需要，请使用全局临时表）。

使用xml内容在Dynamic Sql中创建语句
