URL: http://GPUDB_IP_ADDRESS:GPUDB_PORT/append/records
Append (or insert) all records from a source table (specified by input parameter source_table_name) to a particular target table (specified by input parameter table_name). The field map (specified by input parameter field_map) holds the user specified map of target table column names with their mapped source column names.

Type |
Description |
table_name |
string |
The table name for the records to be appended. Must be an existing table. |
source_table_name |
string |
The source table name to get records from. Must be an existing table name. |
field_map |
map of
string
to
strings |
Contains the mapping of column names from the target table (specified by input parameter table_name) as the keys, and corresponding column names from the source table (specified by input parameter source_table_name). Must be existing column names in source table and target table, and their types must be matched. |

Supported Parameters
(keys) |
Parameter Description |
offset |
A positive integer indicating the number of initial results to skip from source table (specified by input parameter source_table_name). Default is 0. The minimum allowed value is 0. The maximum allowed value is MAX_INT. Default value is '0'. |
limit |
A positive integer indicating the maximum number of results to be returned from source table (specified by input parameter source_table_name). Or END_OF_SET (-9999) to indicate that the max number of results should be returned. Default value is '-9999'. |
expression |
Optional filter expression to apply to the source table (specified by input parameter source_table_name). Empty by default. Default value is ''. |
order_by |
Comma-separated list of the columns to be sorted from source table (specified by input parameter source_table_name) by; e.g. 'timestamp asc, x desc'. The columns specified must be present in input parameter field_map. If any alias is given for any column name, the alias must be used, rather than the original column name. Default value is ''. |
update_on_existing_pk |
Specifies the record collision policy for inserting the source table records (specified by input parameter source_table_name) into the target table (specified by input parameter table_name) table with a primary key. If set to true, any existing target table record with primary key values that match those of a source table record being inserted will be replaced by that new record. If set to false, any existing target table record with primary key values that match those of a source table record being inserted will remain unchanged and the new record discarded. If the specified table does not have a primary key, then this option is ignored. Default value is 'false'. The allowed values are:
