Explanation
The statement "The only way to join two tables is by using standard, ANSI syntax" is false. While standard, ANSI syntax is commonly used for joining tables, there are other ways to join tables as well. For example, some database systems may have their own proprietary syntax for joining tables. Additionally, there are also alternative methods of joining tables, such as using subqueries or table-valued functions. Therefore, the given statement is not entirely accurate.

Explanation
An exclusive lock will deny users any access to a table. This means that only one user or transaction can have exclusive access to the table, while all other users are denied access until the exclusive lock is released. This type of lock is commonly used when performing operations that require exclusive access to the table, such as making structural changes or performing data updates that could be affected by concurrent access.

Explanation
SQL stands for Structured Query Language and is used for managing and manipulating relational databases. While SQL is often referred to as a language, it is actually a declarative language rather than a procedural one. Procedural languages, such as C or Java, involve step-by-step instructions and control flow. In contrast, SQL focuses on specifying what data to retrieve or modify, rather than how to do it. Therefore, the statement that "SQL is a procedural language" is false.

Explanation
The two types of SQL environment are interactive and embedded. The term "embedded" refers to a type of SQL environment where SQL statements are directly incorporated into a programming language or application code. This allows for seamless integration of SQL functionality within the application, making it easier to perform database operations. The options "embed" and "embeded" are variations of the correct term "embedded" and can be used interchangeably.

Explanation
The ALTER statement is used to modify the structure of a table in a database. It can be used to add, modify, or delete columns in a table. The keyword "alter" is the correct syntax to use when adding a column to a table.
