VLOOKUP
=VLOOKUP(lookup_value, table_array, col_index_num,
[range_lookup])
HLOOKUP
=HLOOKUP(lookup_value, table_array, row_index_num,
[range_lookup])
Syntax:
=VLOOKUP(lookup_value,table_array,col_index_num,[range_lookup])
Arguments:
•lookup_value Required
The value to search in the first column of the table or range.
•table_array Required
The range of cells that contains the data.
•col_index_num Required
The column number in the table_array argument from which the
matching value must be returned.
•range_lookup Optional
A logical value that specifies whether you want VLOOKUP to find
an exact match or an approximate match.
Microsoft® Excel® Lookup Functions
Description:
•Searches the first column of a range of cells, and then returns a
value from any cell on the same row of the range.
Remarks:
• The values in the first column of table_array can be text, numbers, or
logical values.
•Uppercase and lowercase text are equivalent.
• If range_lookup is TRUE, the values in the first column of table_array must
be placed in ascending order.
• If range_lookup is TRUE or omitted, an exact or approximate match is
returned.
• If range_lookup is FALSE, an exact match will be attempted, sorting not
required
Microsoft® Excel® Lookup Functions
Errors:
#VALUE! – If col_index_num is less than 1
#REF! – If col_index_num is greater than the number of columns in the
table_array
#N/A – If range_lookup is FALSE and an exact match cannot be found
#N/A – If lookup_value is less than the smallest value in the first
column of table_array

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.

• 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

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

_______ 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.
