Answer & Solution
Answer: Option A
Solution:
The
FROM SQL clause is used to specify from which table we are selecting or deleting data. It defines the source table from which data will be retrieved or modified in a SQL query. Here's the breakdown:
Option A:
specify what table we are selecting or deleting data FROM
This option correctly describes the purpose of the
FROM
clause, which is to specify the table from which data operations will be performed.
Option B: specify range for search condition
This is not the primary purpose of the
FROM
clause. It is used for table specification, not defining search ranges.
Option C: specify search condition
The
FROM
clause is not used to specify search conditions. Search conditions are typically defined in the
WHERE
clause.
Option D: None of these
Option A is a valid description of the
FROM
clause's purpose.
So, the correct answer is
Option A: specify what table we are selecting or deleting data FROM
.
