Eu tenho um problema com uma instrução UPDATE que contém uma instrução SELECT aninhada em combinação com instruções LEFT OUTER JOIN.

Situação: Em nosso banco de dados há uma nova coluna adicionada a todas as pessoas que estão em nosso banco de dados, e quero atualizar a coluna com o valor "X" em determinadas pessoas, mas apenas para as pessoas que possuem determinadas condições.

Com a seguinte instrução SELECT eu seleciono com sucesso todas as pessoas que precisam ter esta coluna atualizada. A coluna que quero atualizar é "Testfield"

SELECT
    TESTDB.CONTACT.number2 AS CustomerID,
    TESTDB.PERSON.firstname AS FirstName,
    TESTDB.PERSON.lastname AS LastName,
    (SELECT UPPER(string19) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) AS Testfield
FROM         
    TESTDB.CONTACT 
    LEFT OUTER JOIN TESTDB.PERSON ON TESTDB.CONTACT.contact_id = TESTDB.PERSON.contact_id
    LEFT OUTER JOIN TESTDB.UDPERSONSMALL ON TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.udpersonSmall_id 
    LEFT OUTER JOIN TESTDB.UDCONTACTLARGE ON TESTDB.CONTACT.userdef2_id = TESTDB.UDCONTACTLARGE.udcontactLarge_id
WHERE 
    (TESTDB.CONTACT.contact_id = TESTDB.PERSON.contact_id) 
/*  No retired people*/
    AND TESTDB.PERSON.retired = '0'
/*  Other conditions*/
    AND ((SELECT UPPER(string05) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'A'
    OR  (SELECT UPPER(string07) FROM CRM5.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'B'
    OR  (SELECT UPPER(string08) FROM CRM5.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'C')
/*  testpersonen*/
    AND (SELECT string45 FROM TESTDB.UDPERSONLARGE WHERE TESTDB.PERSON.userdef2_id = TESTDB.UDPERSONLARGE.UDPERSONLARGE_id) = '123'
ORDER BY
    CustomerID, FirstName, LastName

Resultado:

10001;Test1;Person1;
10001;Test2;Person2;
10001;Test3;Person3;
10001;Test4;Person4;
10001;Test6;Person6;
10001;Test7;Person7;
10001;Test8;Person8;

(7 rows affected)

Isso está correto, as pessoas têm o valor NULL no Testfield no momento. (a quarta coluna está vazia)

Agora quero atualizar a coluna "Testfield", e tentei isso até agora:

UPDATE
    TESTDB.CONTACT 
    LEFT OUTER JOIN TESTDB.PERSON ON TESTDB.CONTACT.contact_id = TESTDB.PERSON.contact_id
    LEFT OUTER JOIN TESTDB.UDPERSONSMALL ON TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.udpersonSmall_id 
    LEFT OUTER JOIN TESTDB.UDCONTACTLARGE ON TESTDB.CONTACT.userdef2_id = TESTDB.UDCONTACTLARGE.udcontactLarge_id
SET
    (SELECT UPPER(string19) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'J'
WHERE 
    (TESTDB.CONTACT.contact_id = TESTDB.PERSON.contact_id) 
/*  No retired people*/
    AND TESTDB.PERSON.retired = '0'
/*  Other conditions*/
    AND ((SELECT UPPER(string05) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'A'
    OR  (SELECT UPPER(string07) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'B'
    OR  (SELECT UPPER(string08) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'C')
/*  testpersonen*/
    AND (SELECT string45 FROM TESTDB.UDPERSONLARGE WHERE TESTDB.PERSON.userdef2_id = TESTDB.UDPERSONLARGE.UDPERSONLARGE_id) = '123'

Mas aqui recebo o erro de que não aceita o LEFT OUTER JOIN colocado aqui:

Msg 156, Level 15, State 1, Server TESTSERVER, Line 3
Incorrect syntax near the keyword 'LEFT'.
Msg 156, Level 15, State 1, Server TESTSERVER, Line 7

Msg 102, Level 15, State 1, Server TESTSERVER, Line 17
Incorrect syntax near '='.
Msg 102, Level 15, State 1, Server TESTSERVER, Line 19

Eu também tentei assim:

UPDATE
    TESTDB
SET
    (SELECT UPPER(string19) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'X'
FROM
    TESTDB.CONTACT 
    LEFT OUTER JOIN TESTDB.PERSON ON TESTDB.CONTACT.contact_id = TESTDB.PERSON.contact_id
    LEFT OUTER JOIN TESTDB.UDPERSONSMALL ON TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.udpersonSmall_id 
    LEFT OUTER JOIN TESTDB.UDCONTACTLARGE ON TESTDB.CONTACT.userdef2_id = TESTDB.UDCONTACTLARGE.udcontactLarge_id
WHERE 
    (TESTDB.CONTACT.contact_id = TESTDB.PERSON.contact_id) 
/*  No retired people*/
    AND TESTDB.PERSON.retired = '0'
/*  Other conditions*/
    AND ((SELECT UPPER(string05) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'X'
    OR  (SELECT UPPER(string07) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'X'
    OR  (SELECT UPPER(string08) FROM TESTDB.UDPERSONSMALL WHERE TESTDB.PERSON.userdef_id = TESTDB.UDPERSONSMALL.UDPERSONSMALL_id) = 'X')
/*  testpersonen*/
    AND (SELECT string45 FROM TESTDB.UDPERSONLARGE WHERE TESTDB.PERSON.userdef2_id = TESTDB.UDPERSONLARGE.UDPERSONLARGE_id) = '123'

Isso resulta em outro erro:

Msg 102, Level 15, State 1, Server TESTSERVER, Line 4
Incorrect syntax near '('.
Msg 102, Level 15, State 1, Server TESTSERVER, Line 4
Incorrect syntax near '='.

Msg 102, Level 15, State 1, Server TESTSERVER, Line 19

O software é um CRM com banco de dados SQL Server 2005.

Alguém poderia me ajudar com a sintaxe? Estou me perdendo.

Desde já, obrigado.
