數字或值錯誤：字符串緩衝區太小

Question

我無法與Oracle應用這種簡單的查詢表達並正在此錯誤：

Query cannot be parsed, please check the syntax of your query. (ORA-06502: PL/SQL: numeric or value error: character string buffer too small)"

SELECT E.EQUIPMENTID, E.EQUIPMENTDESCRIPTION 
From EQUIPMENT as E 
left outer join EQUIPMENT_CHECKOUT as EC  
on E.EQUIPMENTID = EC.EQUIPMENTID 
WHERE EC.EQUIPMENTID is null 

Answer 1

我覺得問題可能出在這誤導案件。你不包括AS時指定表的別名，即：

SELECT E.EQUIPMENTID, E.EQUIPMENTDESCRIPTION 
From EQUIPMENT E 
left outer join EQUIPMENT_CHECKOUT EC 
on E.EQUIPMENTID = EC.EQUIPMENTID 
WHERE EC.EQUIPMENTID is null 

BTW：心尖，你可以嘗試在SQL命令窗口的SQL語句（在SQL車間）通常提供了更好的語法錯誤信息。
