Update Query with INNER JOIN between tables in 2 different databases on 1 server

Need some SQL syntax help :-)

Both databases are on the same server

db1 = DHE
db2 = DHE_Import

UPDATE DHE.dbo.tblAccounts
INNER JOIN DHE_Import.dbo.tblSalesRepsAccountsLink
ON DHE.dbo.tblAccounts.AccountCode = DHE_Import.tblSalesRepsAccountsLink.AccountCode
SET DHE.dbo.tblAccounts.ControllingSalesRep = DHE_Import.dbo.tblSalesRepsAccountsLink.SalesRepCode

I can do a query in Access with linked tables with similar syntax - BUT SQL doesn't like it.

I'm sure it's a simple issue :-D

Thanks!

Should look like this:

UPDATE DHE.dbo.tblAccounts
SET DHE.dbo.tblAccounts.ControllingSalesRep =
DHE_Import.dbo.tblSalesRepsAccountsLink.SalesRepCode
from DHE.dbo.tblAccounts
INNER JOIN DHE_Import.dbo.tblSalesRepsAccountsLink
ON DHE.dbo.tblAccounts.AccountCode =
DHE_Import.tblSalesRepsAccountsLink.AccountCode

Update table is repeated in FROM clause.

Sorry its late, but I guess it would be of help to those who land here finding a solution to similar problem.
The set clause should come right after the update clause. So rearranging your query with a bit change does the work.

UPDATE DHE.dbo.tblAccounts
SET DHE.dbo.tblAccounts.ControllingSalesRep
= DHE_Import.dbo.tblSalesRepsAccountsLink.SalesRepCode
from DHE.dbo.tblAccounts
INNER JOIN DHE_Import.dbo.tblSalesRepsAccountsLink
ON DHE.dbo.tblAccounts.AccountCode
= DHE_Import.tblSalesRepsAccountsLink.AccountCode

It also has other useful code snippets which are commonly used.

update <dbname of 1st table>.<table name of 1st table> A INNER JOIN <dbname of 2nd table>.<table name of 2nd table> RA ON A.<field name of table 1>=RA.<field name of table 2> SET A.<field name of table 1 to be updated>=RA.<field name of table 2 to set value in table 1>


Replace data in `<>` with your appropriate values.

That's It.

//For Access Database:
UPDATE ((tblEmployee
LEFT JOIN tblCity ON (tblEmployee.CityCode = tblCity.CityCode))
LEFT JOIN tblCountry ON (tblEmployee.CountryCode = tblCountryCode))
SET tblEmployee.CityName = tblCity.CityName,
tblEmployee.CountryName = tblCountry.CountryName
WHERE (tblEmployee.CityName = '' OR tblEmployee.CountryName = '')

Update one table using Inner Join

UPDATE Table1 SET name=ml.name
FROM table1 t inner JOIN
Table2 ml ON t.ID= ml.ID

UPDATE table1 a
inner join table2 b on (a.kol1=a.b.kol1...)
SET a.kol1=b.kol1
WHERE
a.kol1='' ...

for me until the syntax worked -MySQL

which may be useful

Update
A INNER JOIN B ON A.COL1=B.COL3
SET
A.COL2='CHANGED', A.COL4=B.COL4,......
WHERE ....;

Following is the MySQL syntax:

UPDATE table1
INNER JOIN table2 ON table1.field1 = table2.field2
SET table1.field3 = table2.field4
WHERE ...... ;

You could call it just style, but I prefer aliasing to improve readability.

UPDATE A
SET ControllingSalesRep = RA.SalesRepCode
from DHE.dbo.tblAccounts A
INNER JOIN DHE_Import.dbo.tblSalesRepsAccountsLink RA
ON A.AccountCode = RA.AccountCode


For MySQL

UPDATE DHE.dbo.tblAccounts A
INNER JOIN DHE_Import.dbo.tblSalesRepsAccountsLink RA
ON A.AccountCode = RA.AccountCode
SET A.ControllingSalesRep = RA.SalesRepCode
