Convert MS SQL Server Query in MYSQL QUERY - mysql

Question

I have written a Query,
SELECT dbo.boat.boatno, dbo.boat.boattype, dbo.staff.staffFirstName, dbo.staff.staffLastName,
dbo.branch.branchAddress
FROM dbo.boat INNER JOIN
dbo.BoatOwner ON dbo.boat.OwnerNo = dbo.BoatOwner.OwnerNo INNER JOIN
dbo.branch ON dbo.boat.BranchNo = dbo.branch.branchno INNER JOIN
dbo.staff ON dbo.branch.branchno = dbo.staff.Branchno
WHERE (dbo.branch.branchAddress LIKE '%LONDON%')
But It doesn't work in MYSQL QUERY
How can i convert this into MYSQL QUERY?

Answer 1

You need to know correct table names for MySQL. Assuming a similar structure, I might try:
SELECT b.boatno, b.boattype, s.staffFirstName, s.staffLastName, br.branchAddress
FROM boat b INNER JOIN
BoatOwner bo
ON b.OwnerNo = bo.OwnerNo INNER JOIN
branch br
ON b.BranchNo = br.branchno INNER JOIN
staff s
ON br.branchno = s.Branchno
WHERE br.branchAddress LIKE '%LONDON%';
MySQL does not use the three-part naming that SQL Server does. There is no "schema" in the middle of the name. The additional periods in the column names are probably one source of confusion. Using table aliases should work in both databases and makes the code more readable.

Just a guess from general principles, but perhaps the simpler
SELECT A.boatno, A.boattype, D.staffFirstName, D.staffLastName, C.branchAddress
FROM dbo.boat A, dbo.BoatOwner B, dbo.branch C, dbo.staff D
WHERE B.OwnerNo = A.OwnerNo AND C.branchno = A.BranchNo AND D.Branchno = C.branchno
AND C.branchAddress LIKE '%LONDON%'
may work.
To begin, make sure also that you can SELECT from dbo.boat, dbo.BoatOwner, dbo.branch and dbo.staff using your PHPmyAdmin environment. Sometimes the simple things trip us up...

SELECT b.boatno, b.boattype, s.staffFirstName, s.staffLastName, br.branchAddress
FROM boat b INNER JOIN
BoatOwner bo
ON b.OwnerNo = bo.OwnerNo INNER JOIN
branch br
ON b.BranchNo = br.branchno INNER JOIN
staff s
ON br.branchno = s.Branchno
WHERE br.branchAddress LIKE '%LONDON%';
GROUP BY b.boatno
Isn't that enought?
