When transferring data such as a picture or a plug-in document through ODBC protocol, the data must be transferred in the form of a BLOB (Binary Large OBject). The BLOB data type is the most generic type that most ODBC compliant applications support. It can be used to store any data types in the raw format and transferred from one application to another without losing the data content type. However, the tricky part is how to insert the data into a blob so that when the data is pulled out of the blob, the data property remains unchanged. This will be the main topic of this technical note. I will demonstrate how send a receive data through ODBC plug-in in various scenarios.
