Answer:
Case-Manipulative Functions: Character-Manipulative Functions (CONCAT, LENGTH, SUBSTR, INSTR, LPAD, RPAD, TRIM, and REPLACE). LOWER: This function changes the case of alpha character values. If the entering string is fixed-length, LOWER will really give back a fixed-length string.
Explanation:
Step 1: Character data manipulation is made possible through character functions. Character functions are occasionally referred to as string functions, much like character datatypes are. These seven character function examples will be covered: LEFT, RIGHT, SUBSTRING, LTRIM, RTRIM, UPPER, and LOWER.
Step 2: The Oracle String functions are more efficient in manipulating character strings. The ASCII function provides the specified character's numerical value. The ASCIISTR function provides the specified character's numerical value. All the characters in the specified ASCII code are returned by the Oracle CHR function.
Step 3: Arguments of type CHAR, NCHAR, VARCHAR, NVARCHAR, or LVARCHAR are accepted by functions that manipulate strings. Anywhere an expression is used, a string manipulation function can be used. The following routines change the case of the letters in a character string between uppercase and lowercase: LOWER.
