Detailed Description

A set of input parameters for createUnion(const CreateUnionRequest&) const.

Creates a table that is the concatenation of one or more existing tables. It is equivalent to the SQL UNION ALL operator. Non-charN 'string' and 'bytes' column types cannot be included in a union, neither can columns with the property 'store_only'.

Parameters

[in]	tableName	Name of the table to be created. Must not be the name of a currently existing GPUdb table. Cannot be an empty string.
[in]	tableNames	The list of table names making up the union. Must contain the names of one or more existing tables.
[in]	inputColumnNames	The list of columns from each of the corresponding input tables.
[in]	outputColumnNames	The list of names of the columns to be stored in the union.
[in]	options	Optional parameters. collection_name: Name of a collection in GPUdb to which the union is to be assigned as a child table. If empty, then the union will be a top level table. Default value is an empty std::map.
