The IDWT2D function outputs a message that indicates whether the function succeeded and an output table of transformed (reconstructed) matrices.
|Message that indicates whether the function was successful.
|Inherited from input table column with same name
|Sequence identifier of the sequence to which the data belongs. Rows with the same partition column values belong to the same sequence.
The output table has a partition_column for every partition_column in the data table.
If the data table has multiple partition columns, the first one is the distribute key in the output table.
If the data table has only one partition_column, the output table has as its distribute key a function-generated column named dwt_idrandom_name. Every cell of dwt_idrandom_name has the value 1.
|Y index of the reconstructed matrix.
|X index of the reconstructed matrix.
|INTEGER, SMALLINT, BIGINT, BIGSERIAL, DOUBLE PRECISION, NUMERIC [(p, s)], or SERIAL
The output table has an input_column for every input_column in the data table.
