MYSQL程序運行但沒有結果

Question

我在創建一個mysql程序的同時執行了程序 - 沒有錯誤。但結果沒有顯示。

CREATE PROCEDURE `proc1`() 

BEGIN 

(SELECT 'idTienda', 'idArticulo', 'Descripcion', 'Peso', 'Precio', 'Importe') 
UNION 

(SELECT idTienda, idArticulo, Descripcion, Peso, Precio, Importe 

FROM dat_ticket_linea 

INTO OUTFILE 'C:/tmp/sales.csv' 
FIELDS ENCLOSED BY '"' 

TERMINATED BY ';' 

ESCAPED BY '"' 

LINES TERMINATED BY '\r\n'); 

END 

感激，如果任何一個可以幫助我解決它
