Call plsql function from esb-xsl mapping

Question

Hi
I want to call a plsql function that takes an inparameter from an xsl mapping file.
I tried to use the orcl:query-database function for this, but i couldn't get it to work when I wanted to dynamically pass the value of the inparameter to the function taken from the XML file used as input in the xsl transformation:
If I hardcode the parameter value like this, it works fine:
orcl:query-database('select emx_parameters.get_parameter_value('DEADLINE') result from dual',false(),false(),'jdbc/DB')
But if i dynamically want to assign the inparameter, it doesn't work for me:
orcl:query-database('select emx_parameters.get_parameter_value('/Header/ParameterName') result from dual',false(),false(),'jdbc/DB')
Maybe it has something to do with the ' signs, but I tried a lot of combinations it nothing worked for me.
Has anyone any ideas how to do this?
Thanks

Hi
If anyone is interested i managed to solve it this way:
I build up the sql query string with xsl variables like this:
<xsl:variable name="start">select emx_parameters.get_parameter_value('</xsl:variable>
<xsl:variable name="param" select='/Header/ParameterName'/>
<xsl:variable name="end">') result from dual</xsl:variable>
<xsl:variable name="expr" select="concat($start,$param,$end)"/>
And then I called the orcl:query-database method with the variable as in-parameter.
orcl:query-database($expr,false(),false(),"jdbc/DB")
Maybe there is another way, but this worked for me.
