It is not really difficult to learn SQL.
SQL is not a programming language, it’s a query language. It is also an English like language so anyone who can use English at a basic level can write SQL query easily. The good news is that most DB engines are compatible with all SQL code.
Is SQL better than Python?
SQL is good at allowing you as a developer, to seamlessly join (or merge) several data together. Python is particularly well suited for structured (tabular) data which can be fetched using SQL and then require farther manipulation, which might be challenging to achieve using SQL alone.
Is SQL the only query language?
In that sense, it is false to say that SQL is the only database query language, as there is no such thing as “the SQL language“; rather you have multiple language implementations, such as Transact-SQL (e.g. as used by Microsoft SQL Server), MySQL, PostgreSQL, Oracle SQL, and so on, which are similar in many aspects,
Is SQL a coding?
listen) S-Q-L, /ˈsiːkwəl/ “sequel”; Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS).

As the SQL acronym pronounces, it is a language. It offers looping, logic directives, variables, and so on. Now, it’s not a language in the same sense as, say, Java or C++: SQL is considered a fourth-generation language (4GL), whereas Java and C++ are third-generation languages (3GLs).
What SQL Cannot do?

Is NoSQL easier than SQL?
In general, NoSQL is not faster than SQL just as SQL is not faster than NoSQL. On the other hand, NoSQL databases are specifically designed for unstructured data which can be document-oriented, column-oriented, graph-based, etc. In this case, a particular data entity is stored together and not partitioned.
Is SQL same as MySQL?
SQL is a query language, whereas MySQL is a relational database that uses SQL to query a database. You can use SQL to access, update, and manipulate the data stored in a database. SQL is used for writing queries for databases, MySQL facilitates data storing, modifying, and management in a tabular format.

Can I learn Oracle by myself?
Oracle is fundamentally just like SQL Server and every other relational database system. Its database architectural principles are the same and it operates with SQL (Structured Query Language), plus Oracle’s own PL/SQL extensions. It’s relatively easy to learn — as long as you have a good handle on Linux and SQL.
