To access format parameters, open the Feature Type Properties dialog by clicking the properties 
button on a feature type in the workspace. These parameters are applicable only to the selected feature type.
General tab
Geometry
This parameter specifies the type of geometry for features to be written to the destination table.

netezza_type |
Database Type(s) |
FME Representation |
|
netezza_none |
Not applicable |
No geometry |
|
netezza_point
|
POINT |
Single point geometry. fme_geometry = fme_point fme_type = fme_point |
|
MULTIPOINT |
Aggregate containing one or more points. fme_geometry = fme_aggregate fme_type = fme_point |
|
|
netezza_line
|
LINESTRING |
Single line geometry. fme_geometry = fme_line fme_type = fme_line |
|
MULTILINESTRING |
An aggregate of linestrings. fme_geometry = fme_aggregate fme_type = fme_line |
|
|
netezza_polygon
|
POLYGON |
A single polygon or donut geometry. fme_geometry = fme_polygon or fme_donut fme_type = fme_polygon |
|
MULTIPOLYGON |
An aggregate of simple polygons or donut polygons. fme_geometry = fme_aggregate fme_type = fme_polygon |
|
| netezza_geometry |
Allows geometries of any of the specific types (points, multipoints, lines, etc.) to be written to the same table. |
|
|
netezza_ |
GEOMETRYCOLLECTION |
An arbitrary collection of geometry. |
When appending to an existing table, if the value of this parameter is incompatible with the geometry column type of the spatial column in the existing table, expect translation failure.
When inserting a geometry, if the type of the geometry is incompatible with the value of this parameter, the translation will fail.
The Format Parameter Write Multi Geometries (see below) modifies this parameter.
Format Parameters tab: Netezza Spatial and Non-Spatial
Overwrite Table
- No: Data will be appended to the existing table.
- Yes: The table will be dropped if it exists, then created.
- TRUNCATE: If the table does not exist, it will be created, and if the table does exist, then all its rows will be deleted.
UPDATE Key Columns
This parameter instructs the Netezza writer to perform UPDATE operations on the table.
The parameter is a comma-separated list of column names (for example, ID,NAME). These column names are used to match the same-named attributes on an input feature against rows in the destination table. Matching rows in the destination table will be updated by the attribute values of the input feature.
Note: If this parameter and DELETE Key Columns are both supplied, translation fails.
DELETE Key Columns
This parameter instructs the Netezza writer to perform DELETE operations on the table.
The parameter is a comma-separated list of column names (for example, ID,NAME). These column names are used to match the same-named attributes on an input feature against rows in the destination table. Matching rows in the destination table will be deleted.
Note: If this parameter and UPDATE Key Columns are both supplied, translation fails.
Format Parameters tab: Additional Parameters for Netezza Spatial
Geometry Column
This parameter can be used to specify the name of a spatial column. If it is not specified, the default name of THE_GEOM will be used.
Write Multi Geometries
This parameter is a modifier for the Geometry parameter (click the General tab in the Feature Type Properties dialog) when its value is one of netezza_point, netezza_polygon, or netezza_linestring.
This parameter can cause these Geometry values to be treated as MULTIPOINT, MULTILINESTRING, and MULTIPOLYGON, respectively.
In the table below, the behavior of this parameter is described in the context of Geometry = netezza_point.
| Yes |
All incoming points will be written out as MULTIPOINT geometries. All single-level point collections will be written out as MULTIPOINT geometries. All nested point collections will be written out as GEOMETRYCOLLECTIONs. |
| No |
All incoming points will be written out as POINT geometries. All incoming collections of points, including nested point collections, will be flattened and written out, one row per point. |
| FIRST_FEATURE |
The first input feature determines whether this parameter is set to Yes or No:
|
Geometry type mismatches result in translation failure. See Geometry above for details.
Note: This parameter is ignored if Geometry is set to netezza_geometry.
Geometry Column Width
Specifies a fixed width for the geometry column.
Any feature whose geometry is larger than this size will be dropped. If this parameter is not specified, then on insertion, the geometry column width will be automatically expanded in size, as needed, up to the maximum size of 64000 bytes.
