ReportParams Structure

Use the ReportParams structure to replace existing filters and variables in an analysis.

The ReportParams structure is common to all web services.

ReportParams Structure Fields

Fields	Description
String[] filterExpressions	Specifies an array of Oracle Analytics web services filter expressions in the form Object[] filter_expression, filter_expression ...
Variable[] variables	Specifies an array of variable values to be set before method execution. This structure is used in executeXMLQuery() method and generateReportSQL() method.
NameValuePair[] nameValues	Should be set to NULL. This field is for internal use only.
TemplateInfo[] templateInfos	Should be set to NULL. This field is for internal use only.
String viewName	Specifies which view to use when generating XML data for the analysis.

How Filter Expressions Are Applied to an Analysis in Web Services

Step	Internal Processing
1	Obtains XML representations of the analysis and each filter expression.
2	For each expression element, locates the child node of the type sqlExpression (the type is determined by the value of the xsi:type attribute), and references its inner text.
3	In the analysis XML, locates all nodes that also have a child node of type sqlExpression where the inner text matches that located in the preceding step.
4	Replaces all nodes found in Step 3 with the expression from Step 2.

How Variables Are Applied to an Analysis in Web Services

Step	Internal Processing
1	Obtains XML representations of the analysis.
2	For each variable, locates all nodes in the analysis XML that have a type of variable, attribute scope equal to analysis, and inner text that matches the variable name.
3	Replaces each node located in Step 2 with the new variable value.
