Specifies the function name for which this .aml file is to be used. For predictors, this represents the type of the model trained. For information about model types, see Aster Scoring SDK Functions.
[Optional] Specifies the model tables that represent the input data for which to generate the .aml file. Each model_table is either a database table or a file that is installed on the database.
[Optional] Specifies an input model table tag for each input model table that the ModelTable argument specifies. Tags are supported for functions that accept multiple model tables and are used to distinguish the role of each model table in the context of the Aster Scoring SDK function.

Specify one model_tag for each model_table. For information about supported tags, see Aster Scoring SDK Functions.

[Optional] Specifies whether the corresponding model_table is a database file. Default: 'false' (that is, the model_table is a database table). If model_table is a database file, specify 'true'. Specify one Boolean for each model_table.
Specifies the column names of the request to be scored. For a predictor, these column names typically match the column names of the training data used to train the model.
Specifies the column types of the request to be scored. For a predictor, these column types typically match the columns types of the training data used to train the model. Specify one column_type for each column_name.
[Optional] Specifies the name for the AML model file that the function outputs. Default: 'model'. The file suffix is .aml. For example, if aml_model_file is 'model', the output file is model.aml.
[Optional] Specifies whether to overwrite the output AML model file if it exists. Default: 'false'.
[Optional] Specifies an argument for function_name. Typically, this argument is the same as it is in the corresponding SQL-MapReduce function. For supported clauses for each function, see Aster Scoring SDK Functions. For argument descriptions, see the documentation for the corresponding SQL-MapReduce function.

The values of n must proceed sequentially from 1. For example: RequestArgName1, RequestArgName2, RequestArgName3. The maximum value of n is 30.

[Optional] Specifies the value or values for the argument that RequestArgNamen specifies. The valid values are the same as they are for the corresponding argument of the SQL-MapReduce function.
