◆ aggregateUnique() \[1/2]

AggregateUniqueResponse kinetica.Kinetica.aggregateUnique ( AggregateUniqueRequest request\_ )
inline

Returns all the unique values from a particular column (specified by column\_name) of a particular table or view (specified by table\_name).

If column\_name is a numeric column, the values will be in data. Otherwise if column\_name is a string column, the values will be in json\_encoded\_response. The results can be paged via offset and limit parameters.

{"{"}"limit":"10","sort\_order":"descending"{"}"}

The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

If a RESULT\_TABLE name is specified in the options, the results are stored in a new table with that name–no results are returned in the response. Both the table name and resulting column name must adhere to standard naming conventions; any column expression will need to be aliased. If the source table's shard key is used as the column\_name, the result table will be sharded, in all other cases it will be replicated. Sorting will properly function only if the result table is replicated or if there is only one processing node and should not be relied upon in other cases. Not available if the value of column\_name is an unrestricted-length string.

Parameters
request\_ Request object containing the parameters for the operation.
Returns
Response object containing the result of the operation.

◆ aggregateUnique() \[2/2]

AggregateUniqueResponse kinetica.Kinetica.aggregateUnique ( string table\_name,
string column\_name,
long offset = 0,
long limit = -9999,
IDictionary\< string, string > options = null )
inline

Returns all the unique values from a particular column (specified by column\_name ) of a particular table or view (specified by table\_name ).

If column\_name is a numeric column, the values will be in data. Otherwise if column\_name is a string column, the values will be in json\_encoded\_response. The results can be paged via offset and limit parameters.

{"{"}"limit":"10","sort\_order":"descending"{"}"}

The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

If a RESULT\_TABLE name is specified in the options , the results are stored in a new table with that name–no results are returned in the response. Both the table name and resulting column name must adhere to standard naming conventions; any column expression will need to be aliased. If the source table's shard key is used as the column\_name , the result table will be sharded, in all other cases it will be replicated. Sorting will properly function only if the result table is replicated or if there is only one processing node and should not be relied upon in other cases. Not available if the value of column\_name is an unrestricted-length string.

Parameters
table\_name Name of an existing table or view on which the operation will be performed, in \[schema\_name.]table\_name format, using standard name resolution rules.
column\_name Name of the column or an expression containing one or more column names on which the unique function would be applied.
offset A positive integer indicating the number of initial results to skip (this can be useful for paging through the results). The default value is 0. The minimum allowed value is 0. The maximum allowed value is MAX\_INT.
limit A positive integer indicating the maximum number of results to be returned, or END\_OF\_SET (-9999) to indicate that the maximum number of results allowed by the server should be returned. The number of records returned will never exceed the server's own limit, defined by the max\_get\_records\_size parameter in the server configuration. Use has\_more\_records to see if more records exist in the result to be fetched, and offset and limit to request subsequent pages of results. The default value is -9999.
options Optional parameters. The default value is an empty Dictionary.
Returns
Response object containing the result of the operation.

◆ AggregateUniqueAsync() \[1/2]

async System.Threading.Tasks.Task\< AggregateUniqueResponse > kinetica.Kinetica.AggregateUniqueAsync ( AggregateUniqueRequest request\_,

If column\_name is a numeric column, the values will be in data. Otherwise if column\_name is a string column, the values will be in json\_encoded\_response. The results can be paged via offset and limit parameters.

Not available if the value of column\_name is an unrestricted-length string.

Parameters
request\_ Request object containing the parameters for the operation.
cancellationToken Cancellation token to cancel the operation.
Returns
Task that returns the response object containing the result of the operation.
