This command instructs pgloader to load data from an IBM IXF file.
Using advanced options and a load command file
The command then would be:
$ pgloader ixf.load
And the contents of the
ixf.load file could be inspired from the following:
LOAD IXF FROM data/nsitra.test1.ixf INTO postgresql:///pgloader TARGET TABLE nsitra.test1 WITH truncate, create table, timezone UTC BEFORE LOAD DO $$ create schema if not exists nsitra; $$, $$ drop table if exists nsitra.test1; $$;
Please refer to Command Clauses for documentation about common clauses.
IXF Source Specification: FROM
Filename where to load the data from. This support local files, HTTP URLs and zip files containing a single ixf file of the same name. Fetch such a zip file from an HTTP address is of course supported.
IXF Loading Options: WITH
When loading from a IXF file, the following options are supported:
When this option is listed, pgloader issues a TRUNCATE command against the PostgreSQL target table before reading the data file.
When this option is listed, pgloader issues an ALTER TABLE … DISABLE TRIGGER ALL command against the PostgreSQL target table before copying the data, then the command ALTER TABLE … ENABLE TRIGGER ALL once the COPY is done.
This option allows loading data into a pre-existing table ignoring the foreign key constraints and user defined triggers and may result in invalid foreign key constraints once the data is loaded. Use with care.
When this option is listed, pgloader creates the table using the meta data found in the DBF file, which must contain a list of fields with their data type. A standard data type conversion from DBF to PostgreSQL is done.
This options expects as its value the possibly qualified name of the table to create.
This options allows to specify which timezone is used when parsing timestamps from an IXF file, and defaults to UTC. Expected values are either UTC, GMT or a single quoted location name such as ‘Universal’ or ‘Europe/Paris’.
