java - Performe nested select statement with Spring JDBC -

-

i have problem executing nested select statement. here sql :

select count(*) posts p p.id in (select u.postid users u) ;

i'm using mysql , working when try mysql workbench when try in application in i'm using spring jdbc, throws me "org.springframework.jdbc.uncategorizedsqlexception."

here how i'm using in app:

getjdbctemplate().queryforobject(sql, integer.class);

i had tried , :

getjdbctemplate().query(sql, new rowcountcallbackhandler());

both ways not working , error.

is there configuration options or allowed me execute such nested select statements ?

edit

the error trace is:

[3d000]; error code [1046]; no database selected; nested exception java.sql.sqlexception: no data base selected         @ org.springframework.jdbc.support.abstractfallbacksqlexceptiontranslator.translate(abstrac tfallbacksqlexceptiontranslator.java:84)         @ org.springframework.jdbc.support.abstractfallbacksqlexceptiontranslator.translate(abstrac tfallbacksqlexceptiontranslator.java:81)         @ org.springframework.jdbc.support.abstractfallbacksqlexceptiontranslator.translate(abstrac tfallbacksqlexceptiontranslator.java:81)         @ org.springframework.jdbc.core.jdbctemplate.execute(jdbctemplate.java:411)         @ org.springframework.jdbc.core.jdbctemplate.query(jdbctemplate.java:466)         @ org.springframework.jdbc.core.jdbctemplate.query(jdbctemplate.java:476)         @ org.springframework.jdbc.core.jdbctemplate.queryforobject(jdbctemplate.java:486)         @ org.springframework.jdbc.core.jdbctemplate.queryforobject(jdbctemplate.java:492)

you didn't configure datasource properly:

example:

   <bean id="datasource"        class="org.springframework.jdbc.datasource.drivermanagerdatasource">       <property name="driverclassname" value="com.mysql.jdbc.driver"/>       <property name="url" value="jdbc:mysql://localhost:3306/test"/>       <property name="username" value="root"/>       <property name="password" value="password"/>    </bean>

you need added database name url, in case test
