Can a Pivot table be created in Oracle 10g?
I am running a stored procedure on ORACLE 10g that truncates and repopulates a table (tbl_A) that contains 2 columns; a list of unique codes and monetary amounts. The number of codes may vary weekly.
I would like to create a second table(tbl_B) that contains a column for each of the names being taken from each of these codes with their monetary amount in that column. Can this be done?
Software/Hardware used:
Tbl_A UNIQUE CODES Amount AAA 100.00 BBB 150.00 CCC 200.00 Tbl_B AAA BBB CCC 100.00 150.00 200.00

Answer Wiki:
Yes, but in 10g it is not as easy as it would be in 11g where the PIVOT clause was introduced.
You could do it using the DECODE function, but you would need to know all the possible codes to construct the query.
Something like this:
<pre>SELECT MAX(DECODE(code,'AAA',amount,NULL)) AAA, MAX(DECODE(code,'BBB',amount,NULL)) BBB, MAX(DECODE(code,'CCC',amount,NULL)) CCC FROM codes;</pre>Since the number of codes may vary, you would probably need to construct this query dynamically inside your procedure. Also, you could use the MODEL clause, as suggested in the following article:
