I have two tables employeedetails and educationdetails
employeedetails
empid name
1 xyz
2 asd
3 pqr
Now this empid is a foreign key in educationdetails
empid qualification Percentage
1 SSC 56
1 HSC 78
1 BE 55
2 SSC 80
2 HSC 67
2 BE 71
I want to update second table educationdetails like for empid 1 i want to change the marks of HSC from 78 to 80
how to do this as we are having 3 rows with same id
First define PRIMARY KEY to table educationdetails
.
Use below query.
UPDATE educationdetails
SET Percentage = 80
WHERE empid=1 AND qualification = 'HSC'
You have to uniquely identify the column you want to update in the educationdetails
table. So you will need to know the empid
and the qualification
of the row you want to amend.
UPDATE educationdetails
SET Percentage = 80
WHERE empid=1 AND qualification = 'HSC'
