We then save the file and open it using the code editor. At the very beginning, the table structure will be described as shown below in the image.

Then we Construct the ALTER SQL query which will add the missing column in the database table on our live site.

For that, we use the below query.

ALTER TABLE <table_name> ADD <column_name> <datatype> AFTER <after_column>

You can also see the structure of the table by clicking on the structure tab in phpMyAdmin.

2. We update the single quotes around the string value to fix this error if it is missing.
