Query parameters for featuer layer.
Properties
| Property | Type | Notes |
|---|---|---|
number | The buffer distance for the input geometries. | |
string | Specify the geodatabase version to be queried. | |
IGeometry | The geometry of the spatial filter. | |
number | This option can be used to specify the number of decimal places for the returned geometries. | |
groupByFieldsForStatisticsinherited | string[] | One or more |
boolean | If true, don't add missed fields into layer.outFields for client query. | |
number[] | Object IDs of records to be queried. | |
orderByFieldsinherited | string[] | One or more |
outFieldsinherited | string[] | The list of fields to be included in the returned result set. |
The definitions for one or more field-based statistics to be calculated. | ||
pageinherited | number | Page number starts from 1, not 0. |
pageSizeinherited | number | Page size. |
boolean | If true, it returns distinct values based on the fields specified in outFields. | |
boolean | If true, the queried features have full precision geometry. | |
boolean | If true, the geometry of each result feature will be returned. | |
boolean | If true, m-values are included in the results if the features have m-values. Otherwise, m-values are not returned. | |
boolean | If true, z-values are included in the results if the features have z-values. Otherwise, z-values are not returned. | |
SpatialRelationship | The spatial relationship to be applied to the input geometry while performing the query. | |
"none" | "standard" | "native" | The sqlFormat parameter can be either standard SQL-92 standard or it can use the native SQL of the underlying data store. | |
TimeExtent | The time instant or the time extent to query. A null value specified for start time or end time will represent infinity for start or end time, respectively. | |
Units | The unit for calculating the buffer distance. | |
whereinherited | string | A where clause for the query. |
gdbVersion
gdbVersion: stringSpecify the geodatabase version to be queried.
geometryPrecision
geometryPrecision: numberThis option can be used to specify the number of decimal places for the returned geometries.
groupByFieldsForStatistics
groupByFieldsForStatistics: string[]One or more jimuFieldName by which the values will be grouped for calculating the statistics.
notAddFieldsToClient
notAddFieldsToClient: booleanIf true, don't add missed fields into layer.outFields for client query.
orderByFields
orderByFields: string[]One or more jimuFieldName by which the features/records will be ordered.
Use ASC for ascending and DESC for descending. The following fields are used to control the ordering.
orderByFields is set to ASC (ascending order) by default if <ORDER> is unspecified.
outFields
outFields: string[]The list of fields to be included in the returned result set.
outStatistics
outStatistics: StatisticDefinition[]The definitions for one or more field-based statistics to be calculated.
returnDistinctValues
returnDistinctValues: booleanIf true, it returns distinct values based on the fields specified in outFields.
returnFullGeometries
returnFullGeometries: booleanIf true, the queried features have full precision geometry.
returnGeometry
returnGeometry: booleanIf true, the geometry of each result feature will be returned.
returnM
returnM: booleanIf true, m-values are included in the results if the features have m-values. Otherwise, m-values are not returned.
returnZ
returnZ: booleanIf true, z-values are included in the results if the features have z-values. Otherwise, z-values are not returned.
spatialRel
spatialRel: SpatialRelationshipThe spatial relationship to be applied to the input geometry while performing the query.
sqlFormat
sqlFormat: "none" | "standard" | "native"The sqlFormat parameter can be either standard SQL-92 standard or it can use the native SQL of the underlying data store.
time
time: TimeExtentThe time instant or the time extent to query. A null value specified for start time or end time will represent infinity for start or end time, respectively.
distance: numberThe buffer distance for the input geometries.
