STRING in Oracle - Examples & AI Generator

Working with string operations in Oracle SQL can be complex, especially since Oracle uses specific functions like CONCAT, SUBSTR, and INSTR instead of a singular STRING command. Learning all the nuanced Oracle STRING syntax is time-consuming and easy to forget. AI2sql offers a no-coding, instant solution: simply describe your string manipulation needs in plain English and receive production-ready, optimized Oracle SQL in seconds — a game-changer for developers switching databases and analysts needing accurate queries fast.

STRING Syntax in Oracle

Oracle handles string operations using different built-in functions. Here are some key string functions and their syntax:

CONCAT(string1, string2): Concatenates two strings.
SUBSTR(string, start_position, length): Extracts a substring.
INSTR(string, substring): Finds the position of a substring.
LENGTH(string): Returns the string length.

Unlike some databases, Oracle doesn't have a general STRING() function. Instead, you use these robust functions depending on your business requirements.
