Search & Reporting screens

Signature

public String ucReportSetUdfMultiSql (
      String[] udfName,		// database name of the UDF
      String sqlStatement,	// standard sql statement
      String problemKey,	// alias for the problem id
      String idList,
      boolean doTitleMap) 	// in clause for problem ids

Notes

This can be used to retrieve arbitrary information to display, using the multi value UDF list handling.

Example

public String ucReportSetUdfMultiSql(
                           String[] udfName, // database name of the UDF
