Method Details

create

@Endpoint(describeByClass=true)
public static SqlDataset create(Scope scope,
 Operand<TString> driverName,
 Operand<TString> dataSourceName,
 Operand<TString> query,
 List<Class<? extends TType>> outputTypes,
 List<Shape> outputShapes)

Factory method to create a class wrapping a new ExperimentalSqlDataset operation.

Parameters:

scope - current scope

driverName - The database type. Currently, the only supported type is 'sqlite'.

dataSourceName - A connection string to connect to the database.

query - A SQL query to execute.

outputTypes - The value of the outputTypes attribute

outputShapes - The value of the outputShapes attribute

Returns:

a new instance of SqlDataset

handle

public Output<? extends TType> handle()

Gets handle.

Returns:

handle.

asOutput

public Output<TType> asOutput()

Description copied from interface: Operand

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

Specified by:

asOutput in interface Operand<TType>
