Error description
Performance of drill-down is extremely slow under DQM and huge data environment. ?The attached testcase illustrates what the users are facing though it is very simplified. ??As per the analysis of the generated SQL when drill-down, they insist that "OR" is included in where clause like below and Cognos is retrieving the unnecessary data from data source. ?We do not feel the slow performance with the described steps as it is sample, there are ten million and more records in their data source and the generated SQL like below causes the slow performance of drill-down, they suspect. ?(They want this to be "AND" instead of "OR")??-----?set fmtonly on SELECT? "Products"."Product_line_code" AS "column0", ? "Products"."Product_type_code" AS "column1", ? "Products"."Product_type" AS "column2", ? "Products"."Product_line" AS "C_sortColumn0", ?
