neo:

Backup-ul full o data la 3 zile

Pai fa restore, afla tabelele si FK cu ceva de genul ( nu pot verifica acum, dar trebuie sa mearga)

SELECT
    FK_Table  = FK.TABLE_NAME,
    FK_Column = CU.COLUMN_NAME,
    PK_Table  = PK.TABLE_NAME,
    PK_Column = PT.COLUMN_NAME,
    Constraint_Name = C.CONSTRAINT_NAME ,
"ALTER TABLE " + FK.TABLE_NAME + " ADD CONSTRAINT "  +  C.CONSTRAINT_NAME + " FOREIGN KEY (" + CU.COLUMN_NAME + ")" +
"REFERENCES " + PK.TABLE_NAME+  "(" + PT.COLUMN_NAME + ")" as SQL


FROM
    INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS C
    INNER JOIN
    INFORMATION_SCHEMA.TABLE_CONSTRAINTS FK
        ON C.CONSTRAINT_NAME = FK.CONSTRAINT_NAME
    INNER JOIN
    INFORMATION_SCHEMA.TABLE_CONSTRAINTS PK
        ON C.UNIQUE_CONSTRAINT_NAME = PK.CONSTRAINT_NAME
    INNER JOIN
    INFORMATION_SCHEMA.KEY_COLUMN_USAGE CU
        ON C.CONSTRAINT_NAME = CU.CONSTRAINT_NAME
    INNER JOIN
    (
        SELECT
            i1.TABLE_NAME, i2.COLUMN_NAME
        FROM
            INFORMATION_SCHEMA.TABLE_CONSTRAINTS i1
            INNER JOIN
            INFORMATION_SCHEMA.KEY_COLUMN_USAGE i2
            ON i1.CONSTRAINT_NAME = i2.CONSTRAINT_NAME
            WHERE i1.CONSTRAINT_TYPE = 'PRIMARY KEY'
    ) PT
    ON PT.TABLE_NAME = PK.TABLE_NAME
ORDER BY
    1,2,3,4

si apoi poti sa recreezi FK  copiind coloana SQL in baza ta( atentie - fa un backup mai intii ... si incearca pe un restore..)
