Lookup
Functions
Syntax:
=INDEX(array,row_num,[column_num])
Arguments:
•array Required
A range of cells or an array constant.
•row_num Optional
Selects the row in array from which to return a value.
oIf row_num is omitted, column_num is required.
•column_num Optional
Selects the column in array from which to return a value.
oIf column_num is omitted, row_num is required.
Microsoft® Excel® Lookup Functions
Description:
• Returns the value of an element in a table or an array, selected by the
row and column number indexes.
Remarks:
• If both the row_num and column_num arguments are used, INDEX
returns the value in the cell at the intersection of row_num and
column_num.
Errors:
#REF! – If row_num and column_num do not point to a cell within array

Microsoft® Excel® Lookup Functions
Syntax:
=MATCH(lookup_value, lookup_array, [match_type])
Arguments:
•lookup_value Required
The value that you want to match in lookup_array.
•lookup_array Required
The range of cells being searched.
•match_type Optional
Specifies how Excel matches lookup_value with values in lookup_array.
oThe number -1, 0, or 1
Microsoft® Excel® Lookup Functions
Description:
• Searches for a specified item in a range of cells, and then returns the
relative position of that item in the range
Remarks:
• The lookup_value argument can be a value (number, text, or logical
value) or a cell reference to a number, text, or logical value.
• MATCH returns the position of the matched value within lookup_array, not
the value itself.
• MATCH does not distinguish between uppercase and lowercase letters
when matching text values.
Errors:
#N/A – If MATCH is unsuccessful in finding a match

Microsoft® Excel® Lookup Functions
Microsoft® Excel® Lookup Functions
Description:
•A combination of INDEX and MATCH can be used as a form of table
lookup.
•It is similar to the VLOOKUP and HLOOKUP function but more flexible.
•It is usually of the form:
=INDEX(some_array, MATCH(some_value, some_array, criteria),
[MATCH(some_value, some_array, criteria)])
Microsoft® Excel® Information Functions
How would you find the count of oranges using INDEX and MATCH?
=INDEX(A1:B5,MATCH("Oranges",A1:A5,0),MATCH
("Count",A1:B1,0))
OR
=INDEX(B1:B5, MATCH("Oranges",A1:A5,0))
Microsoft® Excel® Information Functions
Syntax:
=LOOKUP(lookup_value,lookup_vector, [result_vector])
Arguments:
•Lookup_value Required
a value that LOOKUP searches for in the first vector. Lookup_value can be a
number, text, a logical value, or a name or reference that refers to a value.
•Lookup_vector Required
a range that contains only one row or one column. The values in lookup_vector can
be text, numbers, or logical values. Must be in asending order.
•Result_vector Optional
is a range that contains only one row or column. It must be the same size
as lookup_vector.

least one column label and at least one cell below the column label for
specifying the condition

not place the criteria range below the list
•Make sure the criteria range does not overlap the list

Access creates
__________ databases
◦ Data is stored in
various separate
tables by subject or

◦ The data is related
and can be brought
together in ways that
you specify

_______ are the most important
parts of a database.
______ store your data in rows and
columns. All databases contain
one or more of these.
_______ retrieve and process your
data. They can combine data from
different tables, update your data,
and perform calculations on your
data.
_____ control data entry and data
views. They provide visual cues
that make data easier to work
with.
_______ summarize and print your
data. They turn the data in your
tables and queries into documents
for communicating ideas.

To distinguish one record from
another, tables can contain a
primary key field.
◦ The primary key is an
identifier—such as a part
number, a product code, or
an employee ID—that's
unique to each record.
◦ The primary key should be a
piece of information that
won't change frequently.
◦ When tables relate, the
primary key of one table
becomes a foreign key of the
other table.
