Quick Fix: Resolve ‘no viable alternative at input ‘SELECT”* error by using entity and attribute names with positional parameters. Update your code as shown, ensuring to use TypedQuery and set parameters:
The Problem:
While formulating a PostgreSQL query using Hibernate’s EntityManager, the user encountered an error stating ‘no viable alternative at input ‘SELECT*’.’ This error occurred when attempting to create a TypedQuery using the ‘createQuery’ method. The query in question is ‘SELECT * FROM user_details where user_name = ? LIMIT 1’, which is valid and works correctly when executed directly in a SQL console. The code snippet provided indicates that the query is defined as a static final String and then used to construct a TypedQuery, with a parameter for ‘user_name’. Despite this setup, the error persists.
