Reading and Writing BLOBs on External Database Servers

A description of situations involving BLOB data.

This section covers the following situations:

• Reading data from (or writing data to) an external database server that supports the BLOB data type.

• Configuring Sybase CEP Server and wanting to write BLOB data to (or read it from) an external database server that does not support the BLOB data type, but does support a character/varchar/string data type.

• BLOB Data Background
  Convert BLOB data to a character string in order to store the information on servers that do not typically support the data type.
• Connecting and Communicating with External Database Servers that Do Not Support BLOBs
  Sybase CEP Server performs base64 encoding and decoding for BLOB data when you store it as character data.
• Connecting and Communicating with Database Servers that Support BLOBs
  Connecting and communicating with databse servers that support BLOBs requires either encoding the data in (or decoding it from) base64 format when receiving the data from (or passing it to) external database servers.
