Hi, I am trying to use the following command with the table name 'transaction' mentioned in the xmlexists statement as hard coded.

select distinct name
from nav.xml_stage,
xmltable('$c/dataChanges/table' passing XML_DATA as "c"
COLUMNS name varchar(30) path '@name')
where xmlexists ('$c/dataChanges/table[@name="transaction"]/row[@type="U"]' passing XML_DATA as "c")

But I need to pass the table name value to this statment like

select distinct name
from nav.xml_stage,
xmltable('$c/dataChanges/table' passing XML_DATA as "c"
COLUMNS name varchar(30) path '@name')
where xmlexists ('$c/dataChanges/table[@name='" || table_name || "']/row[@type="U"]' passing XML_DATA as "c")

When I use the "' || table_name || "' as parameter value, it gives error message.

Can someone please help me about how to pass the parameter value.

Thanks

Naveed

try


where xmlexists ('$c/dataChanges/table[@name="$t"]/row[@type="U"]' passing XML_DATA as "c", table_name as "t")

where xmlexists ('$c/dataChanges/table[@name="$t"]/row[@type="U"]' passing XML_DATA as "c", table_name as "t")

Sorry, it did not work.

There is an example in the manual - Constant and parameter marker passing to XMLEXISTS and XMLQUERY - IBM DB2 9.7 for Linux, UNIX, and Windows
