Use of sql group function in orcl:query-database - urgent

Question

All,
Version: 10.1.3.4
Two requirements for me:
1. I want to use sum function in orcl:query-database. How to use it?
For ex: I tried the following
<xsl:value-of select='orcl:query-database("select sum(salary) from emp",false(),false(),"jdbc/DB1")'/>
I got the following error
oracle.xml.sql.OracleXMLSQLException: Character ')' is not allowed in an XML tag name.
When I tried without sum function, it works fine
2. I used the same table, but without the sum function as below
<xsl:value-of select='orcl:query-database("select salary from emp",false(),false(),"jdbc/DB1")'/>
This time, it returns the first employees salary!! I dont understand this logic. I expected either the query returns all the rows else it throws error, but none of them were true!
Can anyone pls explain what is the behavior? I want your reply for both the queries!
Currently I'm in a project where I'm working in the similar scenario, so please guru's let me know ASAP.
Thanks,
Sen

Hi Sen,
Create a normal variable variable in XSLT.
Then use that variable.
I mean variable name='Var_1' select='Your Query'
Now use Var_1/yourcollection/...
I am giving some example
<xsl:variable name="Stopdetails" select="/ns0:MyEBM/ns0:DataArea/ns0:MyEBO/ns0:Stops/ns0:Stop[ns0:StopID=$TempStopId]"/>
            <xsl:variable name="AccStopTypeVar">
                    <xsl:value-of select="$Stopdetails/ns0:StopType"/>
</xsl:variable>If you want you can loop on the created variable.
You can do these in XSL.
But DB calls those things ...it would be better , if u take them out. Spme debugging problems are there with XSL.
