Do you also dislike it to manually convert Excel tables into PostgreSQL? Not having real fun in exporting to CSV, then manually writing the SQL header and importing the stuff in PG? This article here explains how to convert a table into an SQL database via OpenOffice. Essentially you open the Excel (or whatever) table with OpenOffice-Calc, select and copy the full table or a subset to the clipboard, and simply paste it into OpenOffice-Base with the right mouse button. A wizard pops up which let's you define the type of each column and a primary key. Save & done. Can't be easier!

Usage of OpenOffice-Base with various drivers

  • See Database drivers page for overview. There are drivers for PostgreSQL, SQLite and MS-Access mdb files.

PostgreSQL (OpenOffice.org 2.x)

Installation of PostgreSQL driver (MS-Windows and Linux)

  1. download postgresql-sdbc-X.Y.Z.zip driver (take the "recommended" file) and save the file to your disk.
  2. Start OpenOffice, choose 'Tools/Package Manager'. Click on the add button and select the downladed file (DO NOT EXTRACT IT !) in the upcoming File dialog. The driver gets installed now, afterwards, the file is listed in the dialog with state enabled. In case you have installed an older version of the driver, remove it now. Close the dialog.
  3. Restart openoffice (even the quickstarter on windows must be shut down !!!).
  4. Done (did you really close openoffice? Please do.)

Usage of PostgreSQL driver (MS-Windows and Linux)

After starting OpenOffice.org again, use: File -> New -> Database to enter the DB dialog.

  • Connect to existing database (select driver): postgresql
  • Connection settings: We have to define the server ("host") name and the name of the database, probably also the user name in case you have to connect with a different user name. To find out, ask your DB administrator or use in a terminal "psql -l " or, if the database is on a remote server, "psql -h host.mydomain.org -l". An entry may look like this:
       dbname=pgtest host=my.databaseserver.org
  • User name (the login name): yourname
  • Finish brings you to a 'Save as' dialog for the connection, saves these settings as file. This file you can use later to re-establish the connection (instead of defining all again).
  • Then click on 'Tables' in the next screen to see the existing PG tables in the database. Usually the 'public' scheme contains the user tables.
  • The 'Queries' button takes you to the query mode, it contains a graphical query designer.

Installation of PostgreSQL driver (MacOSX)

Please use the JDBC driver.

There are not mac OSX version of official SDBC driver, you can connect your postgreSQL database using the JDBC driver.


1)Download the JDBC driver at : PosgreeSQL
(select the driver for your pgsql version) for example with postgreSQL-8.1 we need to download this driver: 

JDBC 8.1-407 JDBC 2


2) Open Neooffice - preferences:

select : 

  Java

clik on : 

  classpath

click on : 

    add archive   ( aggiungi archivio )

select the downloaded driver

click on : 

  ok

3) Come back to : 

  neooffice - database

In the database configuration window:

at the point : connect to an existant database (collega a un database esistente), select the option : 

  JDBC


clik on : 

 next (avanti)

http://img111.imageshack.us/img111/2128/immagine3uw6.png

insert the url to your pgsql database (in this example we have host=localhost, dbname=grassdb): 

  postgreesql://localhost/grassdb

class driver JDBC : 

  org.postgresql.Driver

click on : 

 try class (classe di prova)

if oll is ok :

clik on : 

  ok

go to the next step

insert : 

 user name

 chek the flag 'request password'

clik on : 

  try connection  ( connessione di prova )

insert :

click on : 

  ok

if oll is ok :

click on 

  end ( fine )

to save the database

MySQL (OpenOffice.org 2.x)


DBF files (OpenOffice.org 2.x)

No installation needed, the driver is included in the standard version of OpenOffice.org.


MS-Access mdb files (OpenOffice.org 2.x)

SQLite files (OpenOffice.org 2.x)

After installation of 'sqliteodbc', add the driver to /etc/odbcinst.ini (either add next lines or create as new file if the file does not yet exist): 

    [SQLite]
    Description=SQLite ODBC Driver
    Driver=/usr/local/lib/libsqlite3odbc.so
    Setup=/usr/local/lib/libsqlite3odbc.so

Now the SQLite driver is available for ODBC. The next step is to add the definition(s) of the database you want to connect to. Add an ODBC Data Source Name (DSN) to your definition file at $HOME/.odbc.ini (replace 'user' and 'mymapset' with the correct entries): 

    [nc_sqlite]
    Description=North Carolina SQLite DB
    Driver=SQLite
    Database=/home/user/grassdata/nc_spm/mymapset/sqlite.db
    # optional lock timeout in milliseconds
    Timeout=2000

Converting Excel, CSV, ... to PostgreSQL/MySQL/... via OO-Base

  • Bringing data into OpenOffice 2.0's database: You can for example open an Excel file with OpenOffice, select contents, then open a DB connection in OpenOfficeBase and paste the table into it. The wizard allows to define the type of each column before creating the table. Using the right mouse button on a column name, you can define it as primary key. Important: If generating a PostgreSQL table, prefix the new table name with "public." (example: public.table1) to avoid that the user name is used as schema name.

Step by step DB import procedure (MS-Windows and Linux)

Here we show how to get a spreadsheet table into a SQL database.

1. Mark and copy to clipboard the relevant table parts in the Excel/CSV/whatever table (OO-Calc):

Open the original table with OpenOffice-Calc. For CSV files, they need the .csv extension.

(see also larger screenshot)

2. Open OO-Base and establish a connection to the database (see above for driver installation):

Go File -> New -> Database to launch OO-Base.

(see also larger screenshot)

(see also larger screenshot)

(see also larger screenshot)

3. In the table wizard, paste (right mouse button) earlier selected OO-Calc spreadsheet into the table section:

First select "table" from left menu, then paste into it:

(see also larger screenshot)

4. A wizard opens, define a table name:

When connecting to PostgreSQL, be sure to write a prefix for the schema, usually "public.":

(see also larger screenshot)

5. Select the columns you want to transfer:

(see also larger screenshot)

6. Define primary key (right mouse button on desired column) and all column types:

WARNING: If you make a mistake in defining the column types, all rows after the first failing conversion will be silently ignored. Verify later that all rows arrived in the final SQL table.

(see also larger screenshot)

7. Save and enjoy. The table is now written into your SQL database.

Note that the conversion can take some time.

You can now connect the table to GRASS, R-stats, ... as you like.

Step by step DB import procedure (MacOSX)

There are not difference between osx and linux.
Look for 'Step by step DB import procedure (MS-Windows and Linux)'.
