Examine this query: SELECT TRUNC (ROUND(156.00,-2),-1) FROM DUAL; What is the result?
Correct Answer: E
The query uses two functions: ROUND and TRUNC. The ROUND function will round the number 156.00 to the nearest hundred because of the -2 which specifies the number of decimal places to round to. This will result in 200. Then the TRUNC function truncates this number to the nearest 10, due to the -1 argument, which will give us 200 as the result since truncation does not change the rounded value in this case. * A. 16 (Incorrect) * B. 160 (Incorrect) * C. 150 (Incorrect) * D. 200 (Incorrect) * E. 100 (Incorrect)
