Hi All ,
I have a problem in which i have one staging table where external party populates the data . My work is to copy these values into my internal tables.
I have 7 internal tables to be populated from this one table. This external party populated table can have duplicate rows , I need to do unique insert which i am doing currently .
My sample code :
Insert into table Internal1 ( a , b,c,d ) select unique a,'hello',c, d from external;
Insert into table internal2( g,k,p,i) select unique a,b,somecolumn, d from external ;
The external table contains a very large amount of data and i feel bad about the code when it hits DB 7 times for 7 inserts.
Can someone suggest a better idea ?
Thanks in advance .
