CHARINDEX in PostgreSQL - Examples & AI Generator

Transitioning to PostgreSQL and looking for CHARINDEX functionality? While CHARINDEX is native to SQL Server for finding a substring’s position, PostgreSQL uses POSITION or STRPOS instead—making migration tricky. If you’re tired of memorizing subtle differences or searching CHARINDEX PostgreSQL examples, AI2sql lets you generate accurate, production-ready queries in 10 seconds with no coding required. It’s instant SQL generation for 50,000+ users in 80+ countries.

CHARINDEX Syntax in PostgreSQL

Because CHARINDEX isn’t available in PostgreSQL, you’d use:

• STRPOS(string, substring)

• POSITION(substring IN string)

These functions return the first occurrence position of a substring within a string. Simple, but remembering exact syntax costs time when moving between databases.

CHARINDEX Examples You Can Generate Instantly

1. Find First Space in Customer Names

SELECT customer_name, STRPOS(customer_name, ' ') AS first_space_pos
FROM customers;

2. Identify Orders Containing a SKU Prefix

SELECT order_id, POSITION('SKU-' IN product_code) AS sku_position
FROM orders
WHERE POSITION('SKU-' IN product_code) > 0;

3. Get Dot Position in Email Usernames

SELECT email, STRPOS(email, '.') AS dot_index
FROM users
WHERE STRPOS(email, '.') > 0;

FAQ: CHARINDEX in PostgreSQL

• Is CHARINDEX available in PostgreSQL? No, but STRPOS() and POSITION() provide the same functionality.

• What’s the main difference in syntax? PostgreSQL uses STRPOS(string, substring), while SQL Server uses CHARINDEX(substring, string)—note the argument order.
