How can I export MySQL query results to Excel or text files?

Outputting MySQL Query Results to External Formats

In this guide, we'll explore methods for exporting the output of MySQL queries to either Microsoft Excel or .txt files.

MySQL's Native Export Mechanism

MySQL offers an efficient way to export query results to a text file using the INTO OUTFILE command. This command allows you to create a comma-separated value (CSV) file that can be easily imported into spreadsheets or other applications. For example:

<code class="sql">SELECT order_id, product_name, qty INTO OUTFILE '/tmp/orders.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n';</code>

Customization Options

The FIELDS, ENCLOSED BY, and LINES TERMINATED BY clauses allow you to customize the exported file. You can specify field delimiters, enclose values in quotation marks, and set the end-of-line character. This enables you to fine-tune the output format to match the requirements of your target application.

Redirecting Query Output

Alternatively, you can also redirect the output of a MySQL query to a local file using your preferred client tool. This is particularly useful when you want the results stored on your local machine instead of on the MySQL server. To do this, use the following syntax:

mysql -user -pass -e "SELECT cols FROM table WHERE cols NOT NULL" > /tmp/output

Output File Management

Keep in mind that the output file should not exist before running the INTO OUTFILE command. Additionally, the MySQL user must have write permissions to the directory you specify for the output file. If you don't provide an absolute path for the output file, it will be saved in the directory specified by the 'datadir' system variable.
