Many times while upgrading or migrating from on-prem to cloud hosted ERP, our customers would like to know if their current AX DB size would be applicable on cloud. Do they need to buy extra DB storage or should that be enough given the number of licenses they are buying. And for any SQL Server DB, you might want to know the size of each table for various reasons. No matter what the scenario is, here is the script to know that and then copy the results to a spreadsheet for further analysis.
1. Run the following script on AxDB in SQL Server management studio.
SELECT t.NAME AS TableName, s.Name AS SchemaName, p.rows, SUM(a.total_pages) * 8 AS TotalSpaceKB, CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceMB, SUM(a.used_pages) * 8 AS UsedSpaceKB, CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceMB, (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB, CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceMB FROM sys.tables t INNER JOIN sys.indexes i ON t.OBJECT_ID = i.object_id INNER JOIN sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id INNER JOIN sys.allocation_units a ON p.partition_id = a.container_id LEFT OUTER JOIN sys.schemas s ON t.schema_id = s.schema_id WHERE t.NAME NOT LIKE 'dt%' AND t.is_ms_shipped = 0 AND i.OBJECT_ID > 255 GROUP BY t.Name, s.Name, p.Rows ORDER BY TotalSpaceMB DESC, t.Name
2. Click on the results tab here. That would select all the rows.
3. Click on Edit -> Copy with headers.
4. Paste the results in an excel file and save the file.
