The STOCK_TRADE table stores
real-time (intraday) trade data. You may want too modify this table to comment out
the constraint statement.
-
Locate the STOCK_TRADE table.
-
Use double dashes to comment out the line that reads:
constraint PK_STOCK_TRADE primary key
(INSTRUMENT_ID, TRADE_SEQ_NBR, TRADE_DATE) on o1
The line should now read:-- constraint PK_STOCK_TRADE primary key
(INSTRUMENT_ID, TRADE_SEQ_NBR, TRADE_DATE) on o1
