unable to run an oracle query
Hello, I currently testing bonita in order to chose a BPM solution for our firm. But I have a problem connecting to my oracle database (oraclient 11h and ojdbc6) with Bonita 6.2.1 community edition I set a connector like this :
driver =oracle.jdbc.driver.OracleDriver URL=jdbc:oracle:thin:@myhost:1521:mysid user + password Query or script = select count(*) from mytable SCRIPT MODE (single value ) "TEST" return the folowing error : java.lang.reflect.InvocationTargetException org.bonitasoft.engine.exception.BonitaRuntimeException: java.lang.ClassCastException: oracle.jdbc.driver.ScrollableResultSet cannot be cast to java.io.Serializable myreset(type java.sql.resultset)= resultset
who can help me please? many thanks
Hi, An integer variable does not work. A solution that works is to create a bigdecimal variable and to converting using this expression : mybigdecimal - java.math.BigDecimal#toString
With a query like select mycol from mytable ....I continue to struggle to solve the problem (java.util.list or arraylist does not work with a n rows x one col return)

Hi Nathanael,
"invalid SELECT batch command 0"
So, are you setting a separator at the query screen? If so and there is just that select that you've set, remove this separator and try again.
Thanks ...indeed, this was the first problem Now my problem is to get the result.... message :
java.lang.reflect.InvocationTargetException org.bonitasoft.engine.exception.BonitaRuntimeException: java.lang.ClassCastException: oracle.jdbc.driver.ScrollableResultSet cannot be cast to java.io.Serializable myreset(type java.sql.resultset)=
Hi!
So, the problem now is the type of your return. Try to catch it with a variable and change de result type from 'rowset' to integer (if I'm right oracle will 'answer' your count with an integer value). It'll probably change your error log as the worst possibility. =p
