ORA-01756：引用字符串沒有正確結束

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

更改線路6

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

Answer 2

6號線好像不是在你的榜樣正確的：

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

您結束此行與' 。要麼您刪除+'，要麼完成您的請求與where聲明...

Answer 3

這個錯誤是相當自我描述，你有一個未終止的報價。

您正在嘗試運行Oracle中的SQL Server代碼。這不起作用。

您不能僅僅通過複製將T-SQL轉換爲PL/SQL。

我更正了語法，但很可能您需要比這更多的工作。

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

這看起來很像tSql，而不是pl SQl，你可能想用||連接Oracle和varchar2中的字符串而不是nvarchar

Answer 5

以下是正確的方式來回答問題........ 運行良好.......... 感謝所有誰幫助......
