Search functions that are not case-sensitive
The SQL search functions UPPER, LOWER, and INITCAP support GLS. They accept multibyte characters in character-type source strings and operate on them.
The returned data type is the same as the type of the source string:
- UPPER converts every letter in a string to uppercase.
- LOWER converts every letter in a string to lowercase.
- INITCAP changes the first letter of a word or series of words to uppercase.
For complete information about these search functions, see the HCL OneDB™ Guide to SQL: Syntax.
