A guy named Anton Scheffer wrote this package that allow you to do querys into an excel file directly (once uploaded to the database of course):
select * from table( as_read_xlsx.read( as_read_xlsx.file2blob( 'DOC', 'Book1.xlsx' ) ) ); SHEET_NR SHEET_NAME ROW_NR COL_NR CELL CEL STRING_VAL NUMBER_VAL DATE_VAL ---------- ---------- ------ ------ ----- --- ---------- ---------- -------------------------- 1 Mijn naam 1 1 A1 N 11 1 Mijn naam 1 2 B1 N 12 1 Mijn naam 1 3 C1 N 13 1 Mijn naam 2 1 A2 N 21 1 Mijn naam 2 2 B2 N 22 1 Mijn naam 2 3 C2 N 23 1 Mijn naam 3 1 A3 N 31 1 Mijn naam 3 2 B3 N 32 1 Mijn naam 3 3 C3 N 33 1 Mijn naam 4 4 D4 S D4 1 Mijn naam 6 2 B6 D 1 Mijn naam 7 2 B7 D 1 Mijn naam 8 2 B8 D 1 Mijn naam 9 2 B9 D 1 Mijn naam 10 2 B10 D 2 Sheet3 2 2 B2 S Test 2 Sheet3 3 3 C3 D 19-JAN-2013 20:17:00 2 Sheet3 4 1 A4 S AntonSome examples
// every sheet and every cell select * from table( as_read_xlsx.read( as_read_xlsx.file2blob( 'DOC', 'Book1.xlsx') ) ); // cell A3 from the first and the second sheet select * from table( as_read_xlsx.read( as_read_xlsx.file2blob( 'DOC', 'Book1.xlsx' ), '1:2', 'A3' ) ) // every cell from the sheet with the name "Sheet3" select * from table( as_read_xlsx.read( as_read_xlsx.file2blob( 'DOC', 'Book1.xlsx' ), 'Sheet3' ) )So once you had your query results you can insert them as needed into your tables
Here's the full package:
