What is the OpenJPA configuration to view SQL query executed in a database? I would like to view the query with all parameters executed in log or console instead of viewing the JPQL query

<property name="openjpa.Log" value="SQL=Trace" />

Enables logging of all SQL statements, minus parameter values.

<property name="openjpa.ConnectionFactoryProperties" value="PrintParameters=true" />

Enables logging of SQL parameters.

If you're using log4j, you can setup your log4j.properties file as follows, which will display both the native SQL query and any parameters:

log4j.rootLogger=WARN, CONSOLE

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%-5p %t %d{ISO8601} %l - %m%n

log4j.category.openjpa.jdbc.SQL=TRACE

  • The configuration you've posted will not log SQL parameters. – Rick May 29 '12 at 13:10
  • It actually does log SQL parameters. See the following example output: INSERT INTO TCATALOG (UIDPK, CATALOG_CODE, DEFAULT_LOCALE, MASTER, NAME) VALUES (?, ?, ?, ?, ?) [params=(long) 200001, (String) catalog133835591682111, (String) en_US, (int) 0, (String) Test Catalog] – Templar May 30 '12 at 05:32

    Fair enough. This behavior depends on the version of OpenJPA you are using. @See for additional details -- https://issues.apache.org/jira/browse/OPENJPA-1678 – Rick May 30 '12 at 12:52

To configure Open JPA for Log4J, you need to do the following in persistence xml

Open JPA Configurations {'property name=”openJpa.Log” value=”log4j”'}

Log4j properties for Open JPA configs

log4j.logger.openjpa.Query=TRACE log4j.logger.openjpa.jdbc.SQL=TRACE

In addition to Rick's answer, there is also the "openjpa.ConnectionFactory2Properties" property for connection factories used for unmanaged connections. (more details here: https://openjpa.apache.org/builds/1.2.3/apache-openjpa/docs/ref_guide_conf_openjpa.html#openjpa.ConnectionFactory2Properties)
