[sqlite] How to read data from mem?

[Sairam Gaddam]

I want to read the mem when the program is inside the sqlite3VdbeExec()
function and in case OP_Insert.


Here the mem consists of entire row to be inserted. When I read the mem
*pData, I found from the member pData->flags that it contains a BLOB. But
when I tried to print BLOB in pData->z, I didnt get correct results. How to
print a BLOB?

I tried to print the contents in it by performing a deep copy of that mem
and converting it to real value using sqlite3VdbeRealValue(). But no
satisfactory result.
Can someone kindly help me how to get data from mem?
