Question

Which of the following isn’t a common error when entering and executing SQL statements?

A) Syntax errors
B) Logical errors
C) Typographical errors
D) Excessive speed errors

Answer 1

The most common errors when entering and executing SQL statements are syntax errors, logical errors, and typographical errors.

Step-by-step explanation:

A) Syntax errors: These are errors that occur when the SQL statement is not written correctly, violating the syntax rules of the SQL language. This can happen when there are missing or misplaced parentheses, quotation marks, or semicolons.

B) Logical errors: These errors occur when the SQL statement is syntactically correct, but it produces incorrect results. For example, using the wrong operator or incorrect logic in the WHERE clause can lead to logical errors.

C) Typographical errors: These errors occur when there are mistakes in typing the SQL statement. It can be as simple as misspelling a table or column name, which can cause the statement to fail.

D) Excessive speed errors: This option is incorrect and not related to common errors in SQL statements. Excessive speed errors are not a recognized classification of SQL errors.
