pushSqlXmlUtil
static void pushSqlXmlUtil(ExpressionClassBuilder acb, MethodBuilder mb, java.lang.String xmlQuery, java.lang.String xmlOpName)
Generate code that pushes an SqlXmlUtil instance onto the stack. The instance will be created and cached in the activation's constructor, so that we don't need to create a new instance for every row.
If the
xmlQuery
parameter is non-null, there will also be code that compiles the query when the SqlXmlUtil instance is created.- Parameters:
acb
- builder for the class in which the generated code livesmb
- builder for the method that implements this operatorxmlQuery
- the XML query to be executed by the operator, ornull
if this isn't an XMLEXISTS or XMLQUERY operatorxmlOpName
- the name of the operator (ignored ifxmlQuery
isnull
)
