Jay is actually having difficulty getting some sleep themselves, but he waited long before advising Gloria the scenario, when he don’t need certainly to started right away and state it.
Line 24 concatenates, or contributes, the brand new SP_part worthy of on parse_string_param factor worth, and you will is sold with an about comma and you may room
That it line casts the new extracted parse_string_param really worth due to the fact a sequence before sequence concatenation. Line twenty five subtracts SP_part about param factor. So it subtraction gets the latest action one to actions the brand new kept techniques closer towards defined foot situation. Line 26 after that recursively calls SP_parse_integer with INOUT parameters param and parse_string_param. The fresh new INOUT variables guarantee that most of the recursive calls compared to that MySQL recursive ask operate on the same parameter research beliefs. Line 28 shuts brand new if the-stop, and lines 31 and 30 intimate brand new held processes in itself.
The original phrase we encouter is actually Nil and therefore once more brings the experience regarding a good builtin phrase you to number in order to a no more outlined value or good zeroed worth or an esteem one wide variety so you’re able to nothing
We shall make use of the 2nd held techniques over – call_SP_parse_integer – to call the new SP_parse_integer kept process. In the range 5, call_SP_parse_integer eter. This makes feel since systems do not need to create changes into value of n. For the a short-hands ways, line sixteen kits INOUT varying to help you an empty string. Observe that we did not need to officially declare it because once the a user-outlined adjustable into MySQL recursive query viewed right here, we are going to only use they to the specific class we shall you want since i work on the new held procedure. We simply cannot initialize they to NULL, while the later MySQL surgery you to need NULL because the a factor will go back NULL beliefs.
