...The developer needs customers residing in Okwana Street only.
Which WHERE clause is correct?
A. WHERE cust.street LIKE 'Okwana_'
B. WHERE cust.street LIKE 'Okwana%'
C. WHERE cust.street LIKE 'Okwana-_-_'
D. WHERE cust.street LIKE 'Okwana-%-%'
E. WHERE cust.street LIKE 'Okwana-__-__'
F. WHERE cust.street LIKE 'Okwana-%%%-%%%%'
The correct answer is E.

The LIKE expression uses wildcard characters to search for strings that match the wildcard pattern. In this case, the query uses the LIKE expression and the % wildcard to find all phone numbers begin with the string ?Okwana-? WHERE cust.street LIKE 'Okwana-%%%-%%%%'.



I think the closest answer is B because we are searching for 'Okwana Street' without any '-' signs.

This question and answer don't seem to match: very messy stuff...
 
It is sorta covered in the JavaRanch Style Guide.
