Does SQL support programming?

It is true that SQL is a language, but it does not support programming as it is not a programming language, it is a command language. We do not have conditional statements in SQL like for loops or if..else, we only have commands which we can use to query, update, delete, etc. data in the database.

What role does SQL have in support of programming language features?

SQL (Structured Query Language) is a database management language for relational databases. SQL itself is not a programming language, but its standard allows creating procedural extensions for it, which extend it to functionality of a mature programming language.

What is SQL Rdbms?

RDBMS stands for Relational Database Management System. RDBMS is the basis for SQL, and for all modern database systems such as MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access. The data in RDBMS is stored in database objects called tables.
