◆ execute()

bool sp_instr_hpop::execute ( THD thd,
uint nextp 

Execute this instruction.

thdThread context
[out]nextpindex of the next instruction to execute. (For most instructions this will be the instruction following this one). Note that this parameter is undefined in case of errors, use get_cont_dest() to find the continuation instruction for CONTINUE error handlers.
