Think of SQL as more a DSL (domain specific language.) W3 schools has some really nice tutorials. I'll give a brief tutorial assuming you know the absolute bare basics of databases such as tables, columns, primary and foreign keys.
First there is your main selector word. That is, shockingly, SELECT. So something like SELECT * FROM Employees would get all entries for the Employees table. This can get more difficult when you need to add something SQL calls JOIN. There are three main flavors but for the most part you'll need to only deal with full inner joins. Outer joins (left and right varieties) are if some of the items you are joining on can be null. Joins are used to connect tables via their relationships. Generally you'll connect one table's primary key to another table's foreign key. Something like SELECT Employees.Name, Addresses.PhoneNumber FROM Employees JOIN Addresses ON Employee.AddressID=Address.ID This would select the employee's name and their phone number, which is stored in a seperate table.
Next there are your DDL (data definition language) and your DML (data manipulation language.) DDL's primary responsability is your INSERT statements. It is pretty much as you'd expect. You insert a bunch of information into a database row. Such as INSERT INTO Employees (id,Name,JobTitle) VALUES (1,'John Doe','Manager') Pretty self explanitory. It will insert an employee, John Doe into the table with the role of Manager.
Then there is DML (data manipulation language) and your DML is mostly in charge of the UPDATE statement. Again pretty much explains itself. You update a row generally from the primary key. Like lets say John Doe gets a promotion. UPDATE Employees SET JobTitle = 'Senior Manager' WHERE id = 1
There is obviously way more than that. I just gave one, and the primary function, of the DDL and DML but there is, obviously more. It should give you some key terms to search google. I'm quite profecient in usage of SQL, database management and database design so I can try and help you out. Once you 'click' with RDBMS (relational database management systems) design and management of these databases is actually quite simple.
