Database

Import into PostGIS

Description

Imports a vector layer currently loaded in QGIS into a PostGIS database. Prior to this a connection between QGIS and the PostGIS database has to be created (for example with the DB Manager).

Parameters

Layer to import [vector: any]
Existing vector layer in QGIS.
Database (connection name) [selection]

Name of the database connection (not the database name).

Options:

  • 0 — local

Default: 0

Schema (schema name) [string]

An existing schema of the selected database can be chosen. By default this is the ‘public’ schema.

Default: public

Table to import to (leave blank to use layer name) [string]

Defines a table name for the imported vector file. By default the name of the vector file is chosen.

Default: (not set)

Primary key field [tablefield: any]

Optional.

Sets the primary key field from an existing field in the vector layer.

Geometry column [string]

Defines the name of the geometry column in the new PostGIS table. Geometry information for the features is stored in this column.

Default: geom

Overwrite [boolean]

Overwrites existing tables having the same name.

Default: True

Create spatial index [boolean]

Specify whether to create a spatial index or not. By default a spatial index is created.

Default: True

Convert field names to lowercase [boolean]

If activated this prevents the field names of the input vector layer from being converted to lowercase. By default field names will be lowercase after the import.

Default: True

Drop length constraints on character fields [boolean]

Specify whether the length constraints on character fields should be dropped or not. By default the length constraints are applied.

Default: False

Outputs

Console usage

processing.runalg('qgis:importintopostgis', input, database, schema, tablename, primary_key, geometry_column, overwrite, createindex, lowercase_names, drop_string_length)

PostGIS execute SQL

Description

Allows a SQL database query to be performed on a PostGIS database connected to QGIS.

Parameters

Database [string]

Name of the database, not the connection name. By default you don’t have to fill in the name, the current database connection will be chosen.

Default: (not set)

SQL query [string]

Defines the SQL query, for example ‘create schema test;’.

Default: (not set)

Outputs
