To answer this question, we need to understand the correct syntax for inserting values into a table in SQL.
Option A) INSERT INTO r4r_team (id, username, exp) VALUES (1, 'r4r01', '2');
This option is correct because it follows the correct syntax for inserting values into specific columns of a table. The column names are specified after the table name in parentheses, and the values are specified after the keyword "VALUES" in parentheses.
Option B) INSERT INTO r4r_team VALUES (1, 'r4r01', '2');
This option is also correct because it follows the shorthand syntax for inserting values into all columns of a table. In this case, the column names are not specified, and the values are directly listed after the table name.
Option C) INSERT INTO r4r_team (id, username, exp) VALUE (1, 'r4r01', '2');
This option is incorrect because it uses the singular form "VALUE" instead of "VALUES". The correct keyword is "VALUES" to insert multiple values at once.
Option D) INSERT INTO table r4r_team (id, username, exp) VALUE (1, 'r4r01', '2');
This option is incorrect because it includes the keyword "table" before the table name. The correct syntax is to directly specify the table name after the "INSERT INTO" statement without using the "table" keyword.
Therefore, the correct answers are options A and B.
