的MySQL [錯誤] 1064

Question

，當我跑在Navicat的EXPLAIN的看法表，無法揣摩出究竟在這個簡短的代碼中的錯誤，我得到這個MySQL錯誤1064：

SET @runningbal = 0; 
SELECT 
cashinflow_v.TxnDate, 
cashinflow_v.TxnType, 
cashinflow_v.Amount,  
@runningbal := @runningbal + cashinflow_v.Amount as Balance 
FROM 
cashinflow_v 
ORDER BY cashinflow_v.TxnDate 

錯誤說：

[SQL] EXPLAIN SET @runningbal = 0; 
SELECT 
cashinflow_v.TxnDate, 
cashinflow_v.TxnType, 
cashinflow_v.Amount, 
@runningbal := @runningbal + cashinflow_v.Amount as Balance 
FROM 
cashinflow_v 
ORDER BY cashinflow_v.TxnDate 

[Err] 1064 - You have an error in your SQL syntax; check the manual that 
corresponds to your MySQL server version for the right syntax to use near 'SET 
@runningbal = 0; 
SELECT 
cashinflow_v.TxnDate, 
cashinflow_v.TxnType, 
cash' at line 1 

如果有人能夠幫助我，我將不勝感激。謝謝！

Answer 1

變化：

來自：

EXPLAIN SET @runningbal = 0; 

到

SET @runningbal = 0; 

Answer 2

的EXPLAIN statement預計無論是表名或這些類型之一的查詢：

• 選擇
• DELETE
• INSERT
• 更換
• UPDATE

它只是沒有設計提供任意的SQL命令的信息（怎麼可能呢？）。

如果您的SQL客戶端是試圖解釋查詢的那個客戶端，則可能需要指示它將腳本代碼處理爲腳本而不是單個語句。
