Delete vs Truncate in MySQL and MS SQL Server

-
Delete vs Truncate in MySQL and MS SQL Server DELETE DELETE is a DML Command. DELETE statement is executed using a row lock, each row in the table is locked for deletion. We can specify filters in where clause It deletes specified data if where condition exists. Delete activates a trigger because the operation are logged individually. Slower than truncate because, it keeps logs. Rollback is possible. TRUNCATE TRUNCATE is a DDL command. TRUNCATE TABLE always locks the table and page but not each row. Cannot use Where Condition. It Removes all the data. TRUNCATE TABLE cannot activate a trigger because the operation does not log individual row deletions. Faster in performance wise, because it doesn't keep any logs. Rollback is possible. DELETE and TRUNCATE both can be rolled back when used with TRANSACTION (TRUNCATE can be rolled back in SQL Server, but not in MySQL ). if there is a PK with auto increment, truncate will reset the counter Learn SQL with us a PCWorkshops !

The Seven Different Types of Coding Blocks in Java

-
Java   Coding Blocks    In Java , the term "coding block" typically refers to a block of code within certain constructs that define the scope and execution context of variables and statements. There are several types of coding blocks in Java, each serving different purposes. Here’s an overview: 1. Method Block A  Java  method block is the section of code within a method. It defines the scope of local variables and contains the statements that make up the method. public class MyClass { public void myMethod () { // Method block starts here int localVariable = 10 ; System.out.println(localVariable); // Method block ends here } } 2. Class Block A  Java  class block is the section of code within a class definition. It contains the class’s fields (variables), methods, and nested classes. public class MyClass { // Class block starts here int instanceVariable; // Field public void myMet...
