ORA-01756：引用字符串没有正确结束

Question

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

更改线路6

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

Answer 2

6号线好像不是在你的榜样正确的：

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

您结束此行与' 。要么您删除+'，要么完成您的请求与where声明...

Answer 3

这个错误是相当自我描述，你有一个未终止的报价。

您正在尝试运行Oracle中的SQL Server代码。这不起作用。

您不能仅仅通过复制将T-SQL转换为PL/SQL。

我更正了语法，但很可能您需要比这更多的工作。

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 4

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

Answer 5

以下是正确的方式来回答问题........ 运行良好.......... 感谢所有谁帮助......
