[100 % fixed] Best way to Fix Database Error?
Prior to fixing the mistake, we need to decide precisely the thing is causing the blunder.
Strategy 1: Repair the Database (DB) 
First we need to check if our data set is OK. In the event that you can see your site regularly and get a mistake when attempting to get to the wp-admin page or get an alternate blunder saying "at least one data set tables are inaccessible. The information base might should be fixed." when you attempt to get to your site, these are obvious indicators that your data set is bad. Fortunately, your information base can undoubtedly be fixed utilizing an underlying WordPress highlight.
Of course the component is incapacitated, so you need to empower it yourself to fix your data set by going into the wp-admin.php file and adding this code:
This basic code of line permits you to fix and streamline your data set. Subsequent to adding this line, essentially explore to
www.yoursite.com/wp-administrator/maint/repair.php.
A page with two comparative alternatives will show up – the principal choice would be the Repair option which will fix your data set and the second would be the Repair and Optimize option which will fix and streamline your information base for future blunders and keep it stable.
The Repair and Optimize error takes additional time than the simple Repair option so in the event that you're short on time, just pick the main alternative.
Another significant thing to keep in mind is that the maintenance page you just opened subsequent to placing the line of code into the wp-admin.php file isn't secure; as anybody ensure you eliminate that little line of code from the wp-admin.php file you put prior after you have effectively fixed your site. Doing this guarantees that nobody will play with your information base choices later on.
Strategy 2: Change Login Credentials
Still no karma on opening your site effectively even in the wake of fixing the information base? You should investigate the data set login settings in the wp-config file. Your data set login accreditations might have quit working since you may have changed your facilitating organisation or some helpful data about your data set which wasn't physically refreshed in the wp-config file.
Open the wp-config file again actually like previously and discover the data set login data; it will presumably be close to the highest point of the document.
It shows the name of the data set as "DB_NAME", the login username as "DB_USER", the login secret key as "DB_PASSWORD", and the information base host as "DB_HOST". In the wake of going through the entirety of this data, do ensure everything is right as WordPress will not have the option to associate with the information base if any of these qualities are wrong.
You can genuinely take a look at your information base outside of WordPress by utilizing PHP MyAdmin which is fundamentally an instrument for getting to and altering MySQL data sets. Be that as it may, be cautious when utilizing this apparatus as it manages your site's information base – there's a great chance of wrecking things.
1-In the wake of signing in from your PHP MyAdmin account, click on your information base from a rundown of data sets on your worker. Make a point to tap on the one which coordinates with the name in the wp-config file which you just checked.
2-Subsequent to tapping on the data set name, you'll be seeing a great deal of names of the tables in your information base. To ensure you have the information base name right, track down the table named wp_options and click on the Browse button close to it.
3-This will take you to a page where you will actually want to see the name, URL, and other general settings of your WordPress site. Ensure it's equivalent to it was in the wp-config file you saw prior. Assuming, be that as it may, it isn't, go fix it in the wp-config file prior to continuing.
Well that is it for the data set name. Continuing on to the secret word and the username, there are a couple of approaches to check if both of those are right. One way is to check the generally existing login username and secret word are right is by making a simple .php file which will test to see whether you can interface with the data set utilizing the login qualifications from the wp-config file or the current login username and secret phrase. To test, basically make a .php file, name it anything you like and add this code to it:
This code permits you to test the association by going to the URL of the record into your program. For instance, on the off chance that I set the name of the .php file to sample-file.php then I'll utilize the URL www.yoursite.com/test file.php. You'll either get an effective association or in the most pessimistic scenario, another mistake with more subtleties, which implies your past login certifications are not working and you need new ones.
To make another data set client and secret phrase we require utilizing an alternate apparatus accessible in cPanel called MySQL Databases. Just go snap on that and under the heading of MySQL Users click Add New User. This will take you to another page which asks you for the new login accreditations.
When you've chosen a username and a secret key, make note of them in the wp-config file. Click Create User to proceed. On the accompanying screen, click on Add User to Database, pick your new username and your WordPress information base and click Add.
Whenever you're finished adding the new client to the information base, just update your wp-config file with the new username and secret phrase. Doing this guarantees your information base name, secret key, and username is 100% right.
