We have started having fun with built-in functions (set of instructions) for strings (character arrays).
- UPPER() — upper case
- LOWER() — lower case
- RTRIM() — trim spaces on the right
- LTRIM() — trim spaces on the left
- RIGHT() — part of a string starting on the right
- LEFT() — part of a string starting on the left
- SUBSTRING() — part of a string in the middle
- LEN() — length of a string
- REPLACE() — to replace part of a string
