Usage Notes
Case-insensitive queries are optimized to take advantage of an index. For example, assume you perform
the following steps:
• Create an index on the EMP table.
• Set the Case Insensitive Query property on ENAME to Yes.
• In Enter Query mode, enter the name ’BLAKE’ into :ENAME.
• Execute the query.
Form Builder constructs the following statement:
SELECT * FROM EMP WHERE UPPER(ENAME) = ’BLAKE’ AND
(ENAME LIKE ’Bl%’ OR ENAME LIKE ’bL%’ OR
ENAME LIKE ’BL%’ OR ENAME LIKE ’bl%’);
The last part of the WHERE clause is performed first, making use of the index. Once the database finds
an entry that begins with bl, it checks the UPPER(ENAME) = ’BLAKE’ part of the statement, and makes
the exact match.
Case Insensitive Query restrictions
If you set this property to Yes, queries may take longer to execute.
