To assign a null value from a bash script to a MySQL database, you need to use the NULL keyword in your SQL query.
Here is an example of how to assign a null value to a specific column in a MySQL table using a bash script:
1
|
value=NULL |
Or assign a specific value:
1
|
value="some_value" |
1
|
sql="INSERT INTO your_table (my_column) VALUES ($value);" |
Or update an existing row:
1
|
sql="UPDATE your_table SET my_column = $value WHERE id = 123;" |
1
|
mysql -u username -p password -e "$sql" your_database |
Replace username
, password
, and your_database
with your MySQL credentials and database name respectively.
By following these steps, you can successfully assign a null value from a bash script to a MySQL database.
