Vladimir Kachanov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5dd40d6... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYjg4ZmQxNTQ5... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-13741?atlOrigin=eyJpIjoiYjg4Zm... ) HHH-13741 ( https://hibernate.atlassian.net/browse/HHH-13741?atlOrigin=eyJpIjoiYjg4Zm... ) LOG_SLOW_QUERY parameter doesn't log query ( https://hibernate.atlassian.net/browse/HHH-13741?atlOrigin=eyJpIjoiYjg4Zm... ) Change By: Vladimir Kachanov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5dd40d6... ) I used parameter AvailableSettings.LOG_SLOW_QUERY to log slow query. But instead of query it logged only PreparedStatement.toString(). As result when I use Oracle JDBC Driver with HicariCP HikariCP , there is no query in logged statement: org.hibernate.SQL_SLOW                   : SlowQuery: 80 milliseconds. SQL: 'HikariProxyPreparedStatement@1363216410 wrapping oracle.jdbc.driver.OraclePreparedStatementWrapper@279aac5f' ( https://hibernate.atlassian.net/browse/HHH-13741#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-13741#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
