In this directory you'll find out some pgloader usage examples.
|
|
|
|
To use them, please first create a pgloader database, then for each example
|
|
the tables it needs, then issue the pgloader command:
|
|
|
|
$ createdb --encoding=utf-8 pgloader
|
|
$ cd examples
|
|
$ psql pgloader < simple/simple.sql
|
|
$ ../pgloader.py -Tvc examples/pgloader.conf simple
|
|
|
|
If you want to load data from all examples, create tables for all of them
|
|
first, then run pgloader without argument.
|
|
|
|
The provided examples are:
|
|
|
|
. simple
|
|
|
|
This dataset shows basic case, with trailing separator and data
|
|
reordering.
|
|
|
|
. errors
|
|
|
|
Same test, but with impossible dates. Should report some errors. If it
|
|
does not report errors, check you're not using psycopg 1.1.21.
|
|
|
|
Should report 3 errors out of 7 lines (4 updates).
|
|
|
|
. clob
|
|
|
|
This dataset shows some text large object importing to PostgreSQL text
|
|
datatype.
|
|
|
|
. cluttured
|
|
|
|
A dataset with newline escaped and multi-line input (without quoting)
|
|
Beware of data reordering, too.
|
|
|
|
. csv
|
|
|
|
A dataset with csv delimiter ',' and quoting '"'.
|
|
|
|
. partial
|
|
|
|
A dataset from which we only load some columns of the provided one.
|
|
|
|
. serial
|
|
|
|
In this dataset the id field is ommited, it's a serial which will be
|
|
automatically set by PostgreSQL while COPYing.
|
|
|
|
. reformat
|
|
|
|
A timestamp column is formated the way MySQL dump its timestamp,
|
|
which is not the same as the way PostgreSQL reads them. The
|
|
reformat.mysql module is used to reformat the data on-the-fly.
|
|
|
|
. udc
|
|
|
|
A used defined column test, where all file columns are not used but
|
|
a new constant one, not found in the input datafile, is added while
|
|
loading data.
|
|
|
|
You can launch all those pgloader tests in one run, provided you created the
|
|
necessary tables:
|
|
|
|
$ for sql in */*sql; do psql pgloader < $sql; done
|
|
$ ../pgloader.py -Tsc pgloader.conf
|
|
|
|
[...]
|
|
|
|
Table name | duration | size | copy rows | errors
