Question 95

Examine the description of the EMPLOYEES table:

Which two statements will run successfully? (Choose two.)

SELECT ‘The first_name is ‘‘ || first_name || ‘‘ FROM employees;

SELECT ‘The first_name is ‘‘‘ || first_name || ‘‘‘‘ FROM employees;

SELECT ‘The first_name is ‘‘‘ || first_name || ‘‘‘ FROM employees;

SELECT ‘The first_name is ‘ || first_name || ‘‘ FROM employees;

SELECT ‘The first_name is \‘‘ || first_name || ‘\‘‘ FROM employees;

Correct Answer: B, D

The valid SQL statements should handle string concatenation correctly with respect to single quotes. Option B correctly escapes single quotes using '''' which concatenates a single quote around the first_name field. Option D simply concatenates 'The first_name is ' with the first_name field without any syntax errors. Other options either use mismatched quotes or invalid concatenation syntax. Therefore, options B and D are the correct choices.

jelenadinere_1

it depends on quotation mark, since we can not copy from this question normally you have to guess where are double qoutes and where are single ones, but if it like that: SELECT 'The first_name is ' " || first_name || ' ' " FROM temp; (column name || first_name || ' ' ) SELECT 'The first_name is ' " || first_name || ' " FROM temp; (column name || first_name || ' ) SELECT 'The first_name is ' || first_name || ' ' FROM temp; ( The first_name is Jhon ) then 3 answers are right: BCD
