Based from Visual Basic Forums, I learned a tip on using Crosstab/Pivot queries. This is presented with SQL Server Execution Plan. It's better to use the concept of the second one compared with the first one. SELECT SUM ( CASE WHEN DATEDIFF( DAY , upload_package_received_date, GETDATE()) = 0 THEN 1 ELSE 0 END ) AS Today, SUM ( CASE WHEN DATEDIFF( DAY , upload_package_received_date, GETDATE()) <= 7 THEN 1 ELSE 0 END ) AS Last_Week, SUM ( CASE WHEN DATEDIFF( DAY , upload_package_received_date, GETDATE()) <= 30 THEN 1 ELSE 0 END ) AS [30 Days Ago] FROM temp_uploadpackage Second Example SELECT ( SELECT COUNT (1) FROM temp_uploadpackage WHERE DATEDIFF( DAY , upload_package_received_date, GETDATE()) = 0) AS Today, ( SELECT COUNT (1) FROM temp_uploadpackage WHERE DATEDIFF( DAY , upload_package_received_date, GETDATE()) <= 7) AS Last_Week, ( SELECT COUNT (1) FROM temp_uploadpackage WHERE DATEDIFF

Here's a query to count number of repeating records based from union all query. Union all query does not remove duplicate records. Here's a sample script: select resultsduplicate.url as job_item, count (resultsduplicate.url) as repeat_occurence from ( SELECT url FROM mainTable where id = 47 and url like '%testsite.com%' and _active = 1 UNION ALL SELECT url FROM detailTable where id = 47 and url like '%testsite.com%' and _active = 1 )resultsduplicate group by resultsduplicate.url having ( count (resultsduplicate.url) >1); Original Source From (Stackoverflow.com)
