Difference between Query plan and SQL

Query plan vs. SQL

A query plan (or query execution plan) is a sequence of steps used to access data in a SQL relational database management system. Structured Query Language (SQL) (pronounced S-Q-L; historically "sequel") is a domain-specific language used to manage data, especially in a relational database management system (RDBMS).
