+Today I needed to export some data from an sqlite tabel to csv, as part of my poverty line project.
+Using [sqlitebrowser](https://sqlitebrowser.org/) I could see the table had to much data and I only wanted 
+to export a few columns. To accomplish this I learned how to create a temporary table and exported that.
+
+    
+```sql
+DROP TABLE IF EXISTS processing_data_export;
+CREATE TEMPORARY TABLE processing_data_export AS
+SELECT x,y, county_id FROM grid;
+```
