1. First thing may be to turn the spreadsheets into tables. It's
trivial to turn a spreadsheet into an Access table (eg
http://databases.about.com/aa123100a.htm).
2. Once you have all the representations in Access, you have a choice
to make: standardise the data representation in Access, or export all
the data in its various models to MySQL and standardise the mess there.
Presumably you know Access much better than MySQL, so you may want to
do this standardisation in Access before exporting to MySQL. In that
case, you'll want to implement logic of the sort I described in Access,
before exporting the data to MySQL.
3. You have choices for how to export tables from Access to MySQL.
Simplest may be to export from Access to text files, then use the MySQL
utility mysqlimport to import the data into a mysql table. Or, you can
also use an Access-to-mysql converter script (Google for them), or a
GUI tool like DbTools, which is freeware. Or (perhaps the most complex
method), you can create the target MySQL table, use ODBCAdmin to create
a DSN for it, and export to that.
Is that the info you are looking for?

Hi,
First of all thank you for your reply.
The table names I've wrote in the e-mail were just for info, I do
use underscore instead of space, as you can see I do the same for the
fields in the table.
In theory it is simple but I need some help on how that will be
"translated" to mysql, I have a concept in mind, but I do not know how
to exactly apply it to the situation.
I am in a situation where I have the data gathered from more
persons and everybody had a personal way of designing the database or
excel table and now I need to build a database that will include all
the data in the tables bellow, that is way I was not able to give you a
table description from mysql since I do not have all the tables
imported into mysql.
After I will import the tables into mysql I have to make somehow
the new table and I would like it to be good, and that it can be
further upgraded ( maybe a new service will need to be entered for a
customer and I need to have all the data in one place ) and to be able
to handle each entry not by using 4 fields that are varchar.
If you / someone can help me with this task I will be very
grateful, as I have said before I am a beginer and do not have much
experience with MySQL.
Best regards and thank you for your advice,
Cristi Stoica

A few points:
1. Instead of spaces, use underscores or nothing in table names
2. If Address_Code contains addresses of Sales_Representatives, it
needs an
column for Sales_Representative ids.
3. One way to merge cp2, cp3 and cp4 would be:
(1) add int 'old_id' columns to cp2, cp3 and cp4,
populate with sequential values such that
old_id values are unique across cp2, cp3 or cp4
(2) make a new customers table structure as desired, and include
the new cp2 cp3 & cp4 old_ids, and
an auto_increment int primary key,
(3) import into customer from cp2, cp3, cp4,
excluding dupes computed without reference to old_id
(4) make a customertype table whose columns include
all columns in cp2 cp3 & cp4 which are not in customers
auto_increment primary key id
customer_id
customer_type (whatever values you want corresponding to cp2
etc)
(5) populate customer_type from joins on
customer and cp2
customer and cp3
customer and cp4
using old_id
(6) drop the old_id column from customers

Hi,
I have the following tables: ( some in Microsoft Access and some in
Excel ) and I want to migrate the data into MySQL and develop an

*1) Sales Representative Code

cp2_packet2 VARCHAR
cp2_user VARCHAR
cp2_customer_phone VARCHAR
cp2_id_serie VARCHAR
cp2_id_number INTEGER
cp2_personal_code INTEGER ( it's the unique code of a person so I
cannot use it as a unique key since a client can have more contracts
and more locations )
*4) Customer Packet 3*
cp3_client_id INTEGER( it is not for the location, so if I select all
the data with this code it can show more than one entry since one
client can have more locations )
cp3_contract_number INTEGER
cp3_customer_name VARCHAR
cp3_customer_packet VARCHAR
cp3_street VARCHAR
cp3_street_number VARCHAR
cp3_block_of_flats_number VARCHAR
cp3_staircase_number VARCHAR
cp3_floor_number VARCHAR ( ground floor is considered P in the
current database and other problems )
cp3_flat_number VARCHAR
*5) Customer Packet 4*

cp4_customer_name VARCHAR
cp4_customer_packet VARCHAR
cp4_street VARCHAR
cp4_street_number VARCHAR
cp4_block_of_flats_number VARCHAR
cp4_staircase_number VARCHAR
cp4_floor_number VARCHAR
cp4_flat_number VARCHAR
Now a little info on the tables:
Customer Packet 3 and 4 client_id are identical, but they do not exist
all the time.
Customer Packet 2,3,4 can be grouped based on street, street_number,
block_of_flats_number, staircase_number, flat_number, the floor number
is not in the Customer Packet 2, but there are a few clients that are
only inf CP2, CP3 or CP4 and I need to add him also, with the data that
I find in the tables, otherwise I will lose this clients and the will
not show up anymore.
>From all the tables I will have to be able to make a new table that
will have all the data, and if a customer is only in the customer
packet 2, let's say, he will have blanks for the other fields in table
CP( Customer Packet)3 and 4.
Lets say consider this example like this:
I have CP2 cable contracts, CP3 internet contracts and CP4 the VoIP
contracts and I need to get all the data in one table.
I will need to be able to have an unique ID for each entry, so that is
way I am thinking of creating a big table with all this data since I
cannot use string as a condition, I've had some problems with imports
from excel/csv into mysql and I would like to be able to control each
location.
I will need to get all this data into a new table that looks like this:
*Custmer Data
*id unique, primary key
customer_name
customer_street
customer_street_number
customer_block_of_flats_number
customer_staircase_number
customer_flat_number
customer_cp2_packet_old ( use cp2_packet_old )
customer_cp2_packet_new ( use cp2_packet_new )
customer_client_id ( you will find it in cp3 or cp4, it should be in
both, but since user error exists, it's not in both. )
customer_cp3_packet ( use cp3_customer_packet )
customer_cp3_name ( use cp3_customer_name )
customer_cp3_contract_number ( use cp3_contract_number )
customer_cp4_packet ( use cp4_customer_packet )
customer_cp4_name ( use cp4_customer_name )
customer_cp4_contract_number ( use cp4_contract_number )
customer_area
customer_container
customer_code
( The customer_area, customer_container, customer_code are based on
street, street number, block of flats number, staircase number)
I think I will have to join the tables, but I have no experience with
joining tables.
MySQL version: 4.0.24
OS: linux
If you have any sugestions or recomandations on how the new table
should look / how to solve this problem please feel free to advise me
since I am willing to learn.
Best regards,
Cristi Stoica
