如何將MySQL查詢輸出保存爲excel或.txt文件？

Question

如何將MySQL查詢的輸出保存到MS Excel工作表？

即使只能將數據存儲在.txt文件中，也沒關係。

Answer 1

從Save MySQL query results into a text or CSV file：

MySQL provides an easy mechanism for writing the results of a select statement into a text file on the server. Using extended options of the INTO OUTFILE nomenclature, it is possible to create a comma separated value (CSV) which can be imported into a spreadsheet application such as OpenOffice or Excel or any other applciation which accepts data in CSV format.

Given a query such as

SELECT order_id,product_name,qty FROM orders 

which returns three columns of data, the results can be placed into the file /tmo/orders.txt using the query:

SELECT order_id,product_name,qty FROM orders 
INTO OUTFILE '/tmp/orders.txt' 

This will create a tab-separated file, each row on its own line. To alter this behavior, it is possible to add modifiers to the query:

SELECT order_id,product_name,qty FROM orders 
INTO OUTFILE '/tmp/orders.csv' 
FIELDS TERMINATED BY ',' 
ENCLOSED BY '"' 
LINES TERMINATED BY '\n' 

In this example, each field will be enclosed in 「double quotes,」 the fields will be separated by commas, and each row will be output on a new line separated by a newline (\n). Sample output of this command would look like:

"1","Tech-Recipes sock puppet","14.95" "2","Tech-Recipes chef's hat","18.95" 

Keep in mind that the output file must not already exist and that the user MySQL is running as has write permissions to the directory MySQL is attempting to write the file to.

語法

SELECT Your_Column_Name 
    FROM Your_Table_Name 
    INTO OUTFILE 'Filename.csv' 
    FIELDS TERMINATED BY ',' 
    ENCLOSED BY '"' 
    LINES TERMINATED BY '\n' 

或者你可以試試這個太

You could try executing the query from the your local client and redirect the output to a local file destination;

Mysql -user -pass -e"select cols from table where cols not null" > /tmp/output

您可以編寫以下代碼來實現這一任務：

SELECT ... FROM ... WHERE ... 
INTO OUTFILE 'textfile.csv' 
FIELDS TERMINATED BY '|' 

，並將結果導出爲CSV，然後導出爲Excel工作表。
