Question

如何运行mysql查询并在csv中输出结果。我知道解决方案应该是这样的：

SELECT col1,col2,col3
 FROM my_table
 INTO OUTFILE '/tmp/orders.csv'
 FIELDS TERMINATED BY ','
 ENCLOSED BY '"'
 LINES TERMINATED BY '\n';

但我的问题是，我有大约15个查询，我想运行所有15个查询和结果存储在多个csv文件中。当前对于第一个查询它工作正常并创建csv文件。但是没有为其他查询创建csv 。请帮助：）

      WHERE CEV1.ATTRIBUTE_ID = 1 
      AND CEV1.ENTITY_ID = CE.ENTITY_ID) AS 'FIRST NAME'
 ,CEV.VALUE AS 'LAST NAME'
FROM CUSTOMER_ENTITY CE, CUSTOMER_ENTITY_VARCHAR CEV
WHERE CE.ENTITY_ID = CEV.ENTITY_ID
     AND CEV.ATTRIBUTE_ID = 2
INTO OUTFILE '$localDrive/DIM_CUSTOMER.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '`'
LINES TERMINATED BY '\n'";
