Question

In an SQL query, which SQL keyword is used to specify the column names to be used in a join?

a) SELECT

b) JOIN

c) WHERE

d) FROM

Answer 1

The question seems to contain a misunderstanding as none of the provided options are used exclusively for specifying column names in a join. In an SQL join, the ON clause is used to specify the joining columns, while SELECT, FROM, JOIN, and WHERE keywords serve other purposes in structuring the query. So the correct answer is option A, D, B and C.

Step-by-step explanation:

In an SQL query, the keyword used to specify the column names that you want to use in a join is not listed in the options you've provided.

However, when performing a join such as an INNER JOIN or LEFT JOIN, you typically use the ON clause to specify the columns that are used for joining the tables.

The SELECT keyword is used to define the columns you want to retrieve from the joined tables, while the FROM clause is used to specify the tables from which to retrieve data.

The JOIN keyword is used to specify the type of join you are performing (e.g., INNER JOIN, LEFT JOIN), but not the column names. Lastly, the WHERE keyword is used to filter records that do not meet a specified condition.
