CONVERT in PostgreSQL - Examples & AI Generator

Switching to PostgreSQL and need to use the CONVERT function? Unlike SQL Server or MySQL, PostgreSQL handles type casting a bit differently, which can be confusing. PostgreSQL doesn't have a direct CONVERT function; instead, it uses the CAST operator or the :: shorthand. Typing out SQL conversions repeatedly slows you down—especially if you're adapting cross-database code. With AI2sql, you can generate optimized type conversions from natural language, instantly and with no manual coding required.

CONVERT Syntax in PostgreSQL

PostgreSQL relies on CAST() or the double-colon syntax for conversions. Here’s how:

CAST(expression AS target_data_type)
expression::target_data_type

Tip: Some cases (like encoding conversion) use the CONVERT function, but for most data type casting, use CAST() or ::.

CONVERT Examples You Can Generate Instantly

1. Convert Customer Birthdate from Text to Date

SELECT customer_id, CAST(birthdate AS DATE) AS birthdate_date
FROM customers;

2. Convert Order Amount from String to Numeric

SELECT order_id, amount::numeric AS amount_value
FROM orders;

3. Change Product Price to Integer for Aggregation

SELECT product_id, price::integer AS price_int
FROM products;

FAQ: CONVERT in PostgreSQL

Does PostgreSQL support the CONVERT keyword?
Classic CONVERT is used for encoding, not type casting. For data types, use CAST() or ::.
Can I use CONVERT to change VARCHAR to INTEGER?
No. Use CAST(column AS INTEGER) or column::integer in PostgreSQL.
