CONVERT in Oracle - Examples & AI Generator

Mastering the CONVERT function in Oracle can be tricky—especially if you're used to SQL Server or working across multiple databases. Oracle's CONVERT is used to translate character set encoding, making data migrations and integrations complex without the right syntax. For SQL developers, analysts, and engineers, memorizing these Oracle-specific differences slows delivery. AI2sql lets you skip the manual lookup: generate production-ready CONVERT queries in 10 seconds, no coding required.

CONVERT Syntax in Oracle

CONVERT Function Overview

The basic Oracle CONVERT syntax translates strings from one character set to another:

CONVERT(char, dest_char_set [, source_char_set])

• char: The source string to convert.

• dest_char_set: The desired character set.

• source_char_set (optional): Original character set.

Note: Unlike SQL Server, Oracle's CONVERT does not handle data type conversions. It's character set-specific.

CONVERT Examples You Can Generate Instantly

1. Customer Names to UTF8 (Data Migration)

SELECT CONVERT(customer_name, 'UTF8', 'WE8ISO8859P1')
FROM customers;

2. Product Descriptions from US7ASCII to WE8MSWIN1252

SELECT product_id, CONVERT(description, 'WE8MSWIN1252', 'US7ASCII') AS converted_description
FROM products;

3. Orders Table: Batch Character Set Conversion

UPDATE orders
SET notes = CONVERT(notes, 'AL32UTF8', 'WE8ISO8859P1');

FAQ: CONVERT in Oracle

When should I use CONVERT vs. CAST in Oracle?

Use CONVERT to change a string's character set. Use CAST for data type conversions (e.g., string to number).

Does Oracle CONVERT support all character sets?

Oracle supports many character sets, but compatibility depends on your database configuration. Check V$NLS_VALID_VALUES for supported sets.
