MYSQL 程序正在运行但没有结果

Question

我创建了一个 mysql 过程，在执行该过程时 - 没有错误。但结果没有显示。

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

如果有人帮我解决这个问题，请感激
