In This Chapter
When the database server calls a DataBlade function, it passes the function an extra argument, called the function parameter. The function parameter stores the following state information about the DataBlade function:
Argument information includes the data types of the arguments and whether the arguments are null
Return-type information includes the data types of the return values and whether these return values are null
The function-parameter structure,
MI_FPARAM
, is the mechanism by which the database server and the DataBlade function communicate about state information.
