DECOMPRESS

Decompresses data using the zlib compression algorithm. The zlib compression algorithm is compatible with WinZip. Use the DECOMPRESS function when you receive data over a wide area network.

Syntax

DECOMPRESS( value, precision)

Argument	Required/ Optional	Description
value	Required	Binary datatype. Data that you want to decompress.
precision	Optional	Integer datatype.

Return Value

Decompressed binary value of the input value.

NULL if the input is a null value.

Example

Your organization has an online order service. You received compressed customer order data over a wide area network. You want to read the data using

Data Integration

and load the data to a data warehouse. You can decompress each row of data using DECOMPRESS for the row.

Data Integration

can then load the decompressed data to the target.
