CAST in MySQL - Examples & AI Generator

The CAST function in MySQL lets you convert data types within your SQL queries—like turning a string into a number, or a number into a date. While CAST is a powerful tool for data transformation, remembering its syntax—especially if you're switching between databases—can slow you down. AI2sql empowers you to generate MySQL CAST queries instantly from plain English—no coding or memorization required. It's the simplest way for analysts, engineers, or developers to ensure correct data types, even across complex databases.

CAST Syntax in MySQL

Standard MySQL CAST Syntax

CAST(expression AS target_data_type)

• expression: The value or column you want to convert.

• target_data_type: The data type you want to convert to (e.g., CHAR, SIGNED, UNSIGNED, DATE).

MySQL-specific note: MySQL's CAST requires standard SQL types. Differences in syntax or availability may apply compared to PostgreSQL or SQL Server.

CAST Examples You Can Generate Instantly

1. Convert String Order Values to Integer

2. Format Customer Date of Birth as String
