- OutputTable
- Specify the name for the table that the function creates to store the coefficients output by the wavelet transform. This table must not exist.
- MetaTable
- Specify the name for the table that the function creates to store the meta information for the wavelet transform. This table must not exist.
- TargetColumns
- Specify the names of the columns in the input table or view that contain the data to transform. These columns must contain numeric values between -1e308 and 1e308. The function treats NULL as 0.
- SortColumn
- Specify the name of the column that defines the order of samples in the sequences to transform. In a time series sequence, the column can consist of timestamp values.If sort_column has duplicate elements in a sequence (that is, in a partition), sequence order can vary, and the function can produce different transform results for the sequence.
- PartitionColumns
- [Optional] Specify the names of the partition columns, which identify the sequences. Rows with the same partition column values belong to the same sequence. If you specify multiple partition columns, the function treats the first one as the distribute key of the output and meta tables.
- Wavelet
- [Required if you omit the wavelet filter table.] Specify a wavelet filter name from the following table.
- WaveletTransformLevel
- Specify the wavelet transform level. The value level must be an integer in the range [1, 1000].
- ExtensionMode
- [Optional] Specify the wavelet transform level. The value level must be an integer in the range [1, 1000].
