Node Js Php Serialize Function

The sqlite3 module provides you with two methods for controlling the execution flow of statements.. It’s safe to nest the serialize() method as follows Each command inside the serialize() function is guaranteed to finish executing before the next one starts.

1. node function
2. node function plant
3. node functions in sap cpi

In your example, the CREATE TABLE will finish before the INSERT gets run If you didn't use serialize() then the CREATE TABLE and INSERT statements would be run in parallel.

node function

node function, node functions in sap pi, node function plant, node function biology, node functions in sap cpi, node functional programming, node function example, node function return, node function return value, node function default value

They would start so quickly one after the other that the INSERT may actually finish before the table has been created, giving you an error about trying to insert data into a table that doesn't exist.. serialize The serialize() method puts the execution mode into serialized mode It means that only one statement can execute at a time.

The serialize() method allows you to execute statements in serialized mode, while the parallelize() method executes the statements in parallel.. After the serialize() method returns, the execution mode is set to the original mode again.. If CREATE TABLE wins the race then the program will work fine But if INSERT wins the race, the program will break with an error.. This is called a race condition, because every time you run your program you might get a different winner.. What does it do? Asynchrony in nodejs is great, except that it makes your code Other statements will wait in a queue until all the previous statements are executed..
