- Method Detail
  - name
```
public final String name()
```
    The name of the transform node.
    
    Returns:
    
    The name of the transform node.
  - hasInputs
```
public final boolean hasInputs()
```
    For responses, this returns true if the service returned a value for the Inputs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - inputs
```
public final List<String> inputs()
```
    The data inputs identified by their node names. You can associate a table name with each input node to use in the SQL query. The name you choose must meet the Spark SQL naming restrictions.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasInputs() method.
    
    Returns:
    
    The data inputs identified by their node names. You can associate a table name with each input node to use in the SQL query. The name you choose must meet the Spark SQL naming restrictions.
  - sqlQuery
```
public final String sqlQuery()
```
    A SQL query that must use Spark SQL syntax and return a single data set.
    
    Returns:
    
    A SQL query that must use Spark SQL syntax and return a single data set.
  - hasSqlAliases
```
public final boolean hasSqlAliases()
```
    For responses, this returns true if the service returned a value for the SqlAliases property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - sqlAliases
```
public final List<SqlAlias> sqlAliases()
```
    A list of aliases. An alias allows you to specify what name to use in the SQL for a given input. For example, you have a datasource named "MyDataSource". If you specify From as MyDataSource, and Alias as SqlName, then in your SQL you can do:
    
    select * from SqlName
    
    and that gets data from MyDataSource.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSqlAliases() method.
    
    Returns:
    
    A list of aliases. An alias allows you to specify what name to use in the SQL for a given input. For example, you have a datasource named "MyDataSource". If you specify From as MyDataSource, and Alias as SqlName, then in your SQL you can do:
    
    select * from SqlName
    
    and that gets data from MyDataSource.
  - hasOutputSchemas
```
public final boolean hasOutputSchemas()
```
    For responses, this returns true if the service returned a value for the OutputSchemas property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - outputSchemas
```
public final List<GlueSchema> outputSchemas()
```
    Specifies the data schema for the SparkSQL transform.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasOutputSchemas() method.
    
    Returns:
    
    Specifies the data schema for the SparkSQL transform.
  - toBuilder
```
public SparkSQL.Builder toBuilder()
```
    Specified by:
    
    toBuilder in interface ToCopyableBuilder<SparkSQL.Builder,SparkSQL>

  - serializableBuilderClass
```
public static Class<? extends SparkSQL.Builder> serializableBuilderClass()

  - equalsBySdkFields
```

```
    Specified by:
    
    equalsBySdkFields in interface SdkPojo
  - toString
```
public final String toString()
```
    Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
    
    Overrides:
    
    toString in class Object
  - getValueForField
```
