How to Insert NULL Data into a MySQL Database Using Python?

Inserting NULL Data into MySQL Database with Python

Inserting blank data variables into a MySQL database using Python can result in errors. To address this issue, you can change the blank variables to NULL values, which are accepted by MySQL without adding any data.

To convert a blank variable to NULL using mysqldb and cursor.execute(), assign the value None to the variable instead of "NULL." The following code demonstrates this:

<code class="python">value = None
cursor.execute("INSERT INTO table (`column1`) VALUES (%s)", (value,))</code>

This will insert NULL into the column1 column of the table table.

This solution avoids using an IF statement to convert blank variables to 0, which could interfere with subsequent data analysis in MySQL. By setting the value to None, you ensure that the database recognizes the absence of data without modifying its actual value.
