Inserting 1 Lac rows

Postby intelsami » Tue Mar 15, 2011 5:33 pm

Hi,

I have one task where i need to insert around 1 lac rows in a table by selecting the data from another table. I tried with
' INSERT INTO table1 (col1,col2)
SELECT col3, col4 FROM table2 WHERE cond1 = something; '

This will work if structure of table1 and table2 are same. But in our requirement we have different table structures. Can anyone help me out with this

Thanks

not true, this will work as long as col1 is compatible with col3 and col2 with col4.
There is absolutely no requirements for identical structures in your example.
I can explain it to you, but i can not understand it for you.

It would help if you could use normal units, according to Wikipedia, "lac" i's "the scarlet resinous secretion of a number of species of insects". Never knew DB2 could store this stuff, even though is called a "Universal Database"...

it' s the usual issue of people using local wording in a multilingual forum
from wikipedia
lac == lakh == 100000 units
crore = 100 lakhs

... always from wikipedia
... associated to the fact The Indian numbering system also uses separators differently from the Western system —
besides the three least significant digits of the integer part, a comma divides every two rather than every three digits, thus:
12,31,23,123 123,123,123

...so it's back to 1's and 0's - Simple, universal and does exactly what it says on the tin!
If the code hasn't been changed, why is the LKED date today?
