Home -> Community -> Mailing Lists -> Oracle-L -> RE: Modify data from select before insert.
If you are just doing basic string processing, INSTR and SUBSTR will probably be what's needed. For example
INSERT INTO table1( col1 )
SELECT SUBSTR(col1, 1, 2) || '-' || SUBSTR(col1, 3)
FROM table2
Will add a dash as the third character of col1.

Subject: Modify data from select before insert.
Hello guys,
I could use a few tips here.
I have a sql statement:
insert into table1
(
col1
)
select col1 from tabl2;
Problem is, I need to modify the data in the column from table2 first before inserting to table1. Like add a dash, after the third character ... chnage all A's to B's sort of thing.
Can you guys give me a few hints and perhaps a few keywords I can use to search google for?
Thank you very much.
