Vector general¶

설명¶

<put algorithm description here>

Parameters¶

Input layer [vector: any]

<put parameter description here>

Outputs¶

Output [vector]

<put output description here>

Console usage¶

processing.runalg('qgis:deleteduplicategeometries', input, output)

설명¶

This algorithm allows to execute an SQL query on a set of input vector layers thanks to the virtual layer provider.

Parameters¶

Input layer [vector: any]

<put parameter description here>

Additional data sources [vector]

Data sources that have to be loaded for reference in the SQL query. Any layer already loaded in QGIS is available in the query through its name or id. But for use of this algorithm in a script, input sources should be set here. Each input data source can be referred to as input1 ... inputN as layer names in the query.

Query [string]

The SQL query. SQLite, Spatialite and QGIS expression functions can be used here.

Unique identifier field [string]

Optional parameter to specify which field of the query should be used as a unique id.

Geometry field [string]

Optional parameter to specify which field should be considered as the geometry field, if one wants to avoid possibly slow autodetection.

Geometry type [selection]

Optional parameter to specify the type of the geometry if one wants to avoid possibly slow autodetection.

Geometry types:

• 0 — Autodetect
• 1 — NoGeometry
• 2 — Point
• 3 — LineString
• 4 — Polygon
• 5 — MultiPoint
• 6 — MultiLineString
• 7 — MultiPolygon

Geometry CRS [crs]

Optional parameter to specify the coordinate system of the geometry if one wants to avoid possibly slow autodetection.

Outputs¶

Output [vector]

Output vector

Console usage¶

processing.runalg('qgis:executesql', inputs, query, uid, geom_field, geom_type, crs)

Default: []

Attribute summary [selection]

<put parameter description here>

Options:

Statistics for summary (comma separated) [string]

Optional.

<put parameter description here>

Default: 0

Outputs¶

Joined layer [vector]

<put output description here>
