setDataHeader Procedure

This procedure sets the XML data header. The data header is an XML entity that is appended at the beginning of the query-generated XML entity (that is, rowset). The two entities are enclosed by the tag specified via the docTag argument. Note that the last data header specified is the one that is used; furthermore, passing in NULL for the header parameter unsets the data header.

Syntax

DBMS_XMLQUERY.setDataHeader (

ctxHdl  IN ctxType, 
header  IN CLOB := null, 
tag  IN VARCHAR2 := null);
