QUESTION 1
You have a SqlDataReader object named ordersDataReader. This object contains a column named
OrderQuantity that has an integer value. This object also contains one row for each order received
during the previous week.
You need to write code that will process each row in ordersDataReader and pass OrderQuantity to a
function named myFunction.
Actualtests.org - The Power of Knowing
Which code segment should you use?
A. long weeklyOrderQuantity = 0;
while (ordersDataReader.Read()) {
myFunction((int)ordersDataReader["OrderQuantity"]);
}
B. long weeklyOrderQuantity = 0;
while (ordersDataReader.NextResult()) {
myFunction((int)ordersDataReader["OrderQuantity"]);
}
C. long weeklyOrderQuantity = 0;
int orderCount = 0;
while (orderCount < ordersDataReader.FieldCount) {
myFunction((int)ordersDataReader["OrderQuantity"]);
orderCount++;
ordersDataReader.Read();
}
D. long weeklyOrderQuantity = 0;
int orderCount = 0;
while (orderCount < ordersDataReader.FieldCount) {
myFunction((int)ordersDataReader["OrderQuantity"]);
orderCount++;
ordersDataReader.NextResult();
}
Answer: A
Explanation: The SqlDataReader.Read method advances the SqlDataReader to the next record. The return
value is true if there are more rows; otherwise, false. We can therefore use it as the condition in the while
loop.
Reference: .NET Framework Class Library, SqlDataReader.Read Method [C#]
Incorrect Answers
B: SqlDataReader.NextResult method advances the data reader to the next result, when reading the
results of batch Transact-SQL statements. There is not a batch of Transact SQL statements in this
scenario however.
C, D: The SqlDataReader.FieldCount property gets the number of columns in the current row. It would be
incorrect to use this value in the condition expression for the while loop.
QUESTION 2
Your Microsoft SQL Server database has a stored procedure named GetCompanyName. Ge accepts
one parameter named @CustomerID and returns the appropriate company name.
You instantiate a SqlCommand object named CKCommand. You need to initialize CKCommand to
return the company name for @CustomerID with a value of "ALFKI".
Which code segment should you use?
Donwload Free Certbible, The Most Realistic Practice Questions and Answers,Help You Pass any Exams
Actualtests.org - The Power of Knowing
A. CKCommand.CommandText = "GetCompanyName, ALFKI";
CKCommand.Parameters.Add("@CustomerID");
B. CKCommand.CommandText = "GetCompanyName";
CKCommand.Parameters.Add("GetCompanyName", "ALFKI");
C. CKCommand.CommandText = "@CustomerID";
CKCommand.Parameters.Add("GetCompanyName", "ALFKI");
D. CKCommand.CommandText = "GetCompanyName";
CKCommand.Parameters.Add("@CustomerID", "ALFKI");
Answer: D
Explanation: The SqlCommand.CommandText Property gets or sets the SQL statement or stored procedure
to execute at the data source. Here we should set it to the name of the stored procedure: GetCompanyName.
The Parameter should contain ParameterName (here @CustomerID) and the Value (here the string ALFKI).
Note: An SqlCommand object represents a Transact-SQL statement or stored procedure to execute against a
SQL Server database.
Reference:
.NET Framework Class Library, SqlCommand.CommandText Property [C#]
.NET Framework Class Library, SqlParameter Members
Incorrect Answers
A, C: The CommandText should be set to the named of the stored procedure. We should not specify any
parameters in the CommandText.
B: The name of the parameter, not the name of the stored procedure, should be included in the
parameter.
QUESTION 3
You have a SqlDataReader object named CKproductsDataReader. The productsDataReader object
contains three columns in the following order:
1. ProductID as Integer
2. ProductName as nvarchar(40)
3. UnitsInStock as Integer
You want to use CKproductsDataReader to create an inventory management report. You define the
following three variables:
1. int myProductID;
2. string myProductName;
3. int myUnits;
You need to ensure that the report runs as quickly as possible.
Which code segment should you use?
A. myProductID = (int) CKproductsDataReader[1];
myProductName = (string) CKproductsDataReader[2];
myUnits = (int) CKproductsDataReader[3];
B. myProductID = (int) CKproductsDataReader[0];
myProductName = (string) CKproductsDataReader[1];
myUnits = (int) CKproductsDataReader[2];
Actualtests.org - The Power of Knowing
C. myProductID = (int) CKproductsDataReader["ProductID"];
myProductName = (string)
CKproductsDataReader["ProductName"];
myUnits = (int) CKproductsDataReader["UnitsInStock"];
D. myProductID = (int)
CKproductsDataReader.GetOrdinal("ProductID");
myProductName = (string)
CKproductsDataReader.GetOrdinal("ProductName");
myUnits = (int)
CKproductsDataReader.GetOrdinal("UnitsInStock");
Answer: B
Explanation: We should use ordinal-based lookups since they are more efficient than named lookups.
Column ordinals are zero-based: ProductId has ordinal number 0, myProductName has ordinal number 1,
and myUnits has ordinal number 2.
Incorrect Answers
A: Column ordinals are zero-based, not one-based.
C: Ordinal-based lookups are more efficient than named lookups.
D: The DataReader.GetOrdinal method gets the column ordinal, given the name of the column. We are
not interested in the Ordinal numbers. They should only be used to speed up the process.
Reference: .NET Framework Class Library, SqlDataReader.GetOrdinal Method [C#]
