STRING in PostgreSQL - Examples & AI Generator

Working with strings in PostgreSQL can be tricky—syntax for concatenation, pattern matching, or manipulation tends to differ from other databases and requires memorization of details like || operators, CONCAT(), or position-based functions. For SQL developers, data analysts, and engineers juggling syntax, stumbling on errors or slowdowns is common. AI2sql solves this instantly: describe your intent in natural language, and it returns correct, optimized STRING queries for PostgreSQL—no coding required.

STRING Syntax in PostgreSQL

PostgreSQL provides robust string manipulation functions:

• Concatenation: Uses || or CONCAT(string1, string2, ...).

• Substring extraction: SUBSTRING(string FROM start FOR length)

• Pattern search: POSITION(substring IN string)

• Case conversion: UPPER(string), LOWER(string)

PostgreSQL STRING syntax differs from MySQL and SQL Server, so attention to detail is vital.

STRING Examples You Can Generate Instantly

1. Concatenate Customer First and Last Names

SELECT first_name || ' ' || last_name AS full_name
FROM customers;

Combine fields for readable names in a mailing list.

2. Extract Order Year from Order Date

SELECT order_id, SUBSTRING(order_date FROM 1 FOR 4) AS order_year
FROM orders;

Quickly summarize orders by year for business reporting.

3. Find Products Containing a Specific Keyword

SELECT product_name
FROM products
WHERE POSITION('eco' IN LOWER(product_name)) > 0;

Filter for products advertised with sustainability keywords.
