SQL Server / Forwarded Records / Rebuild the Heap Tables Script
Posted by Barac in SQL Server on Jun 9th, 2020 | 0 comments
I was working with a customer having DB with more than 100K HEAP tables. Number of Forwarded Records on some tables were huge. They are using Ola Hallengren‘s scripts to maintain non-clustered indexes on those tables, but rebuilding those indexes do not fix the forwarded records on those HEAP tables. You actually need to rebuild the HEAP ALTER TABLE TableName REBUILD; Or to add a clustered index to the table (permanent fix). They are in the middle of the remodeling their DB so adding clustered indexes on those HEAP tables was not an option....

SQL Server / PowerShell / Exporting data from a SQL Server table to multiple comma-separated value (CSV) files using PowerShell
Posted by Barac in Powershell, SQL Server, SQL Tips and Tricks on Jan 28th, 2020 | 0 comments

For this example I will use test table with 17220 rows. First step is to export whole table to CSV file using export-csv cmdlet. Export-CSV converts objects into a series of comma-separated value (CSV) strings and saves the strings to a file. If you want to find more details about Export-CSV cmdlet and see more usage examples you can read this MS article. param (...
