Can I get the SQL string from a JPA Query object?

Question

May I know how can I get the sql from a JPA query? or let\'s say, convert the JPA query to a SQL string? Thank you very much!

Answer 1

Using Hibernate as a provider you can enable the following properties:

hibernate.show_sql  

Write all SQL statements to console. This is an alternative to setting the log category org.hibernate.SQL to debug. (e.g. true | false)

hibernate.format_sql

Pretty print the SQL in the log and console. (e.g. true | false)

Or, as stated above you can enable logging to the debug level for the logger

org.hibernate.SQL

Log all SQL DML statements as they are executed
