I am new to MYSQL queries so I am struggling with this.
I have two tables
Table 1
id phone1 phone2 name ...
1 123 456
3 234 567
7 345 678
Table 2
id p1 p2 age ...
1 1123 2456
7 1345 2678
3 1234 2567
ID is the same for both tables. Both tables have many other rows.
I want to copy the data from Table 2 to Table 1 such that the id stays the same.
So the output should be
Table 1
id phone1 phone2 name
1 1123 2456
3 1234 2567
7 1345 2678
Already answered :
In your case :
UPDATE table1 t1
INNER JOIN table2 t2 ON t2.id = t1.id
SET t1.phone1 = t2.p1,
t1.phone2 = t2.p2;
Try This.
UPDATE table1 tbl1
JOIN table2 tbl2
ON tbl2.id = tbl1.id
SET tbl1.phone1 = tbl2.p1,
tbl1.phone2 = tbl2.p2;
UPDATE Table1 tab1
INNER JOIN Table2 tab2 ON tab2.id = tab1.id
SET
tab1.Column2 = tab2.Column3;
