- 
class systemds.script_building.script.DMLScript(context: SystemDSContext)¶
- DMLScript is the class used to describe our intended behavior in DML. This script can be then executed to get the results. - 
add_code(code: str) → None¶
- Add a dml code line to our script - Parameters
- code – the dml code line 
 
 - 
add_input_from_python(var_name: str, input_var: systemds.script_building.dag.DAGNode) → None¶
- Add an input for our preparedScript. Should only be executed for data that is python local. - Parameters
- var_name – name of variable 
- input_var – the DAGNode object which has data 
 
 
 - 
build_code(dag_root: systemds.script_building.dag.DAGNode) → None¶
- Builds code from our DAG - Parameters
- dag_root – the topmost operation of our DAG, result of operation will be output 
 
 - 
execute() → py4j.java_gateway.JavaObject¶
- If not already created, create a preparedScript from our DMLCode, pass python local data to our prepared script, then execute our script and return the resultVariables - Returns
- resultVariables of our execution 
 
 - 
execute_with_lineage() → Tuple[py4j.java_gateway.JavaObject, str]¶
- If not already created, create a preparedScript from our DMLCode, pass python local data to our prepared script, then execute our script and return the resultVariables - Returns
