TRIM in Oracle - Examples & AI Generator

Remembering the Oracle TRIM function's syntax can slow down even experienced SQL developers, especially when switching between database systems. With Oracle's flexible TRIM syntax and options for trimming characters or whitespace from strings, errors are common and productivity drops. AI2sql offers a solution—generate accurate TRIM queries from natural language in just 10 seconds, no coding required. Skip memorization and focus on analyzing your data, whether you’re a SQL developer or a business analyst.

TRIM Syntax in Oracle

• Basic usage: TRIM(string)

• Remove both leading and trailing: TRIM(BOTH 'char' FROM string)

• Remove only left: TRIM(LEADING 'char' FROM string)

• Remove only right: TRIM(TRAILING 'char' FROM string)

Unlike other databases, Oracle TRIM syntax lets you specify which side and which character to remove, not just spaces. This flexibility can lead to accidental mistakes when switching databases.

TRIM Examples You Can Generate Instantly

Here are three TRIM Oracle examples you can copy and adapt to real-world business data:

1. Remove trailing spaces from customer names

SELECT TRIM(TRAILING ' ' FROM customer_name) AS cleaned_name
FROM customers;

2. Strip asterisks from BOTH sides of product codes

SELECT TRIM(BOTH '*' FROM product_code) AS trimmed_code
FROM products;

3. Remove a leading hyphen from order IDs

SELECT TRIM(LEADING '-' FROM order_id) AS normalized_order_id
FROM orders;
