 Usage Case Suggestions

• Resolving concept/modifier codes is a very time consuming task. It is strongly recommended to enable this function only as a last step, after you are sure that the query itself is perfect.
• The default export CSV file encloses all data cells in quotation marks ("). This is necessary to export special characters like line breaks within a cell. However, some statistics software may get confused with the quotation marks. In this case, check the 'Exclude CSV Cell Delimiter (") Where Possible' box on the "Settings" tab to permit the writing of quotation marks where possible. Cells with special characters will still be enclosed in quotation marks, though... but it will be way less work to remove them manually than if it had to be done for every cell...
• If a query would return very large result sets, the server automatically pages the result. This causes a considerable delay that sometimes will fail or hang, due to timeouts. If you encounter this problem, the query can be paged manually by setting the 'Query Page Size' value on the "Settings" tab. This is still slower than an 'at-once' query, but faster than automatic paging and it avoids server overload. The necessary value cannot be predicted in general and strongly depends on the number of observations returned, but 20 - 50 is a good idea for beginning. Higher values result in faster processing but higher risk of server overload.
• If a patient set contains thousands of patients, and you are not sure if the concepts you are specifying would result in large run time or large result set, then it is better to start with a subset of the patient set (e.g. 'Starting Patient': 1, and 'Number of Patients: 500, etc.) first, as you can always run again with subsequent subsets (e.g. 'Starting Patient': 501, and 'Number of Patients: 500, etc.).
• The '1 row per observation (detailed, 1 column per observation detail)' option of tabulation is the only output option where the 'Observation Value' column will contain the appropriate 'Observation BLOBs' (if the 'valuetype_cd' is 'B' and the user has the "DATA_DEID" access right).
