please let me know the issue with following script (sql,oracle 10g)

  1  DECLARE @colname AS NVARCHAR(50)
  2  DECLARE @tablename AS NVARCHAR(500)
  3  DEClARE @query AS NVARCHAR(500)
  4  SET @colname = 'select wk_units1 from cnt_sls_dm.fct_sales_summary'
  5  SET @tablename = 'SELECT tablename from dmi_user.fct_sales_meta'
  6  set @query='select '+@colname+' FROM '+@tablename+'
  7* EXECUTE sp_executesql @query
SQL> /
ERROR:
ORA-01756: quoted string not properly terminated

Answer 1

这个错误非常自我描述，你有一个未终止的引用。

您正试图在SQL Server中运行Oracle代码。这不起作用。

您只能通过复制将T-SQL变为PL/SQL。

我更正了语法，但很可能你需要做的工作要多得多。

DECLARE
    colname NVARCHAR2(50);
    tname   NVARCHAR2(500);
    query   NVARCHAR2(500);
BEGIN
    SELECT  wk_units1
    INTO    colname
    FROM    cnt_sls_dm.fct_sales_summary;
    SELECT  tablename
    INTO    tname
    FROM    dmi_user.fct_sales_meta;
    query := 'SELECT ' || colname || ' FROM ' || tname;
END;

Answer 2

将第6行更改为

set @query='select '+@colname+' FROM '+@tablename

Answer 3

第6行在您的示例中似乎不正确：

set @query='select '+@colname+' FROM '+@tablename+'

您使用'完成该行。要么删除+'，要么使用where声明完成请求...

Answer 4

这看起来很像tSql而不是pl SQl，你可能想要使用||连接Oracle和varchar2中的字符串而不是nvarchar
