Copy value column from a table to other table

[dani33l_87]

Hi,

 

 

How can I copy the value from a column (table nw_items) to other table (nw_products). or even better, into a column (in nw_products) that already exists and has all values set to 0 ?

 

I tried this

 

INSERT INTO nw_products (ID_PLAYER)

SELECT nw_items.ID_OWNER

FROM nw_items;

 

and got this error :#1062 - Duplicate entry '0-0' for key 'PRIMARY'

Give us a clue.

 

What is the structure of said tables and how are they related?

suppose you have two tables table1 and columnname1 as column and table2 with columnname2 as column then the query would look like

 

 

 

UPDATE table1,table2 SET table1.columnname1=table2.columnname1 where table2.columnname1=something;

 

 

the error is for inserting duplicate values in the column with primary key check for that
