Update a mysql column via bash script
Hello,
I want to check the value of all MySQL columns.(column name is "status") via bash script.
If value is "0" at I want to make only single column value to "1"
I have many "0" values on mysql database(on "status" column)
"0" means it is a draft post. I want to publish a post. I want for every check/update just single post to publish.( first found or random)
Table name: files
column name: status
Thank you very much.
