Page 62: Correction To Question 70-229-02.02.012
------------------------------------------------
On page 62, the correct answer for question 70-229.02.02.012 should be A, not B.
Change the text to be:
"Correct Answers: A
A. Correct: When a unique index exists, UPDATE or INSERT statements that would
generate duplicate key values are rolled back, and SQL Server displays an error
message. This is true even if the UPDATE or INSERT statement changes many rows
but causes only one duplicate. If an attempt is made to enter data for which
there is a unique index and the IGNORE_DUP_KEY clause is specified, only the
rows violating the UNIQUE index fail. When processing an UPDATE statement,
IGNORE_DUP_KEY has no effect.
SQL Server does not allow the creation of a unique index on columns that already
include duplicate values, whether or not IGNORE_DUP_KEY is set. If attempted,
SQL Server displays an error message; duplicates must be eliminated before a
unique index can be created on the column(s).
B. Incorrect: see explanation for A.
C. Incorrect: see explanation for A."
Pages 137 & 209: @@ROWS Should Be @@ROWCOUNT
--------------------------------------------
On page 137, in the first answer B, and on page 209, in the second entry under
Symbols, change:
"@@ROWS"
To:
"@@ROWCOUNT"
