How Can I Retrieve Hibernate Query Strings with Their Parameter Values?

Retrieve query string with parameter value in Hibernate

The implementation of Hibernate queries may involve the use of parameter placeholders (question marks) to represent dynamic values ​​in SQL statements. While this approach is efficient, it can hinder visibility into the actual execution of the query.

Use Hibernate API

Hibernate's API itself does not directly support printing query strings with parameter values.

Use logging

An alternative is to enable logging for the following categories:

• org.hibernate.SQL: Set to "debug" to log SQL DML statements during execution
• org.hibernate.type: Set to "trace" to log all JDBC parameters

In a log4j configuration this might look like:

<code># 记录SQL语句
log4j.logger.org.hibernate.SQL=debug 

# 记录传递给查询的JDBC参数
log4j.logger.org.hibernate.type=trace </code>

This method is similar to hibernate.show_sql=true, but will also print the bound parameters.

Non-Hibernate solution: JDBC proxy driver

Another option is to use a JDBC proxy driver such as P6Spy. This tool intercepts and logs JDBC calls, providing insight into the actual query and its parameters.
