我試圖執行此查詢,但我收到以下錯誤:缺少關鍵字選擇查詢
ORA-00905: missing keyword
00905. 00000 - "missing keyword"
*Cause:
*Action:
Error at Line: 25 Column: 51
查詢是:
SELECT egt.education_guarantee_type_id, egt.description, egt.is_available, egy.year_number
FROM mo_education_guarantee_types egt
INNER JOIN mo_education_guarantee_years egy;
什麼關鍵字是從我的查詢失蹤?
你需要一個連接條件,例如INNER JOIN mo_education_guarantee_years egy ON egt.col = egy.col – jarlh
你應該告訴它連接哪一列。請參見[SQL Inner Join](http://www.w3schools.com/sql/sql_join_inner.asp)語法。 – mason
