COMPRESS

Compresses data using the zlib compression algorithm. The zlib compression algorithm is compatible with WinZip. Use the COMPRESS function before you send large amounts of data over a wide area network.

Syntax

COMPRESS( value )

Argument	Required/ Optional	Description
value	Required	String datatype. Data that you want to compress.

Return Value

Compressed binary value of the input value.

NULL if the input is a null value.

Example

Your organization has an online order service. You want to send customer order data over a wide area network. The source contains a row that is 10 MB. You can compress the data in this row using COMPRESS. When you compress the data, you decrease the amount of data

Data Integration

writes over the network. As a result, you may improve task performance.
