How to print a query string with parameter values

Question

Is it possible in Hibernate to print generated SQL queries with real values instead of question marks?

How would you suggest to print queries with real values if it is not possible with Hibernate API?

Answer 1

You can log this:

net.sf.hibernate.hql.QueryTranslator

Output example:

2013-10-31 14:56:19,029 DEBUG [net.sf.hibernate.hql.QueryTranslator] HQL: select noti.id, noti.idmicrosite, noti.fcaducidad, noti.fpublicacion, noti.tipo, noti.imagen, noti.visible, trad.titulo, trad.subtitulo, trad.laurl, trad.urlnom, trad.fuente, trad.texto  from org.ibit.rol.sac.micromodel.Noticia noti join noti.traducciones trad where index(trad)='ca' and noti.visible='S' and noti.idmicrosite=985 and noti.tipo=3446

2013-10-31 14:56:19,029 DEBUG [net.sf.hibernate.hql.QueryTranslator] SQL: select noticia0_.NOT_CODI as x0_0_, noticia0_.NOT_MICCOD as x1_0_, noticia0_.NOT_CADUCA as x2_0_, noticia0_.NOT_PUBLIC as x3_0_, noticia0_.NOT_TIPO as x4_0_, noticia0_.NOT_IMAGEN as x5_0_, noticia0_.NOT_VISIB as x6_0_, traduccion1_.NID_TITULO as x7_0_, traduccion1_.NID_SUBTIT as x8_0_, traduccion1_.NID_URL as x9_0_, traduccion1_.NID_URLNOM as x10_0_, traduccion1_.NID_FUENTE as x11_0_, traduccion1_.NID_TEXTO as x12_0_ from GUS_NOTICS noticia0_ inner join GUS_NOTIDI traduccion1_ on noticia0_.NOT_CODI=traduccion1_.NID_NOTCOD where (traduccion1_.NID_CODIDI='ca' )and(noticia0_.NOT_VISIB='S' )and(noticia0_.NOT_MICCOD=985 )and(noticia0_.NOT_TIPO=3446 )

Answer 2

All of the answers here are helpful, but if you're using a Spring application context XML to setup your session factory, setting the log4j SQL level variable only gets you part of the way there, you also have to set the hibernate.show_sql variable in the app context itself to get Hibernate to start actually showing the values.

ApplicationContext.xml has:

<property name="hibernateProperties">
            <value>
            hibernate.jdbc.batch_size=25
            ... <!-- Other parameter values here -->
            hibernate.show_sql=true
            </value>
 </property>

And your log4j file needs

log4j.logger.org.hibernate.SQL=DEBUG

Answer 3

**If you want hibernate to print generated sql queries with real values instead of question marks.**
**add following entry in hibernate.cfg.xml/hibernate.properties:**
show_sql=true
format_sql=true
use_sql_comments=true

**And add following entry in log4j.properties :**
log4j.logger.org.hibernate=INFO, hb
log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE
log4j.appender.hb=org.apache.log4j.ConsoleAppender
log4j.appender.hb.layout=org.apache.log4j.PatternLayout

Answer 4

Use Wireshark or something similar:

None of the above mentioned answers will print sql with parameters properly or is a pain. I achieved this by using WireShark, which captures all sql/commands being send from the application to Oracle/Mysql etc with the queries.
