They are the same.

From Wikipedia:

SQL (/ˈɛs kjuː ˈɛl/ "S-Q-L"[4]; Structured Query Language[5][6][7][8]) is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS).

Some people pronounce it "S-Q-L", while others pronounce it "sequel".
