Answer:

(a) Variable

Explanation:

In the programming world, a variable is used to store data that can be referenced and modified in a computer program. It typically refers to the label for the location (in memory) of a particular data used in programs. For example;

var b = 12.

This implies that the value 12 is stored in a location in memory that is labeled as b. Anytime the value 12 is needed either for retrieval or modification purposes, it can be referenced by simply calling the variable b.

Answer:

The correct answer is

D. The number of items in the column list doesn't match the number in the VALUES list.

Explanation:

When performing an insert action, the number of values to be inserted into each columns Must match the number of the columns that have been mentioned.

Now let us look at the question as given:

INSERT INTO InvoiceCopy (VendorID, InvoiceNumber, InvoiceTotal, PaymentTotal, CreditTotal, TermsID, InvoiceDate, InvoiceDueDate) VALUES (97, '456789', 8344.50, 0, 0, 1, '2016-08-01')

From the insert statement above, we have declared the system to insert into 8 columns( VendorID, InvoiceNumber, InvoiceTotal, PaymentTotal, CreditTotal, TermsID, InvoiceDate, InvoiceDueDate) of the table InvoiceCopy, but the number of values to be inserted into each column respectiveley is 7. So the statement will try to insert value 97 into column VendorID, Value 456789 into column InvoiceNumber, Value 8344.50 into InvoiceTotal, Value 0 into column PaymentTotal, Value 0, into Column CreditTotal, Value 1, into Column TermsID, Value '2016-08-01' into Column InvoiceDate, But null will be inserted into Column InvoiceDueDate, However, the Question states that None of these columns Accept Null Values. This means that we have to specify values for EVERY column we want to insert into. Because of this number mismatch, the computer will throw an error. This is what is Wrong with the statement.

An insert statement is used to add new values to a database. When performing an insert statement, there are 3 main information that needs to be defined:

The name of the table that the new data is being inserted into
The name of the columns that you want to insert the values into
The actual values that you want to add to the columns mentioned in (2) above.

The basic syntax of an insert statement is as follows:

INSERT INTO table_name (column1_name, column2_name, ...)

VALUES (data_for_column1, data_for_column2, ...);
