Hello
I have a test table with the following structure (2 columns: ID and time_id )and data
1;"2015-01-01"
2;""
3;""
4;"2015-01-02"
5;""
6;""
7;""
8;"2015-01-03"
9;""
10;""
11;""
12;""
13;"2015-01-05"
14;""
15;""
16;""
I'd like to update line 2 and 3 with the date in record 1 (2015-01-01)
Update line 5,6 and 7 with the date in record 4 (2015-01-02) and so on
How about simple SQL instead of PlSql:
UPDATE test T1 SET time_id = (SELECT T2.time_id FROM test T2 WHERE T2.id =
(SELECT max(T3.id) FROM test T3 WHERE T3.id < T1.id AND T3.time_id IS NOT NULL)
)
WHERE T1.time_id IS NULL;
Regards,
Igor Neyman
