Option 1: Create and Update
Option 2: Insert and Select
Option 3: Delete and Insert
Option 4: Create and Insert

Answer 1

The given statements involve the SQL operations of (3) Delete and Insert.

Step-by-step explanation:

In SQL, the operation of deleting records from a table is represented by the DELETE statement, and the operation of inserting new records into a table is represented by the INSERT statement. Option 3, "Delete and Insert," accurately captures the SQL operations performed in the given statements.

This combination of operations suggests a scenario where existing data is deleted from a table, and new data is inserted in its place or in another table.

Option 3 is correct.

Answer 2

The given SQL statements involve creating a table (CREATE) and inserting data into it (INSERT). These operations fall under Data Definition Language (DDL) and Data Manipulation Language (DML), respectively.

Option 4: Create and Insert

Step-by-step explanation:

In the given SQL statements, the operations performed are the creation of a table (`Create`) and the insertion of data into that table (`Insert`). These operations are carried out using SQL Data Definition Language (DDL) and Data Manipulation Language (DML) statements, respectively.

Create Operation:

The `CREATE` statement is used to define a new table in the database. It specifies the table name, along with the columns and their data types. This operation is part of Data Definition Language (DDL) and is used for creating database objects like tables, indexes, etc. In the context of the given options, the `Create` operation signifies the creation of a table.

Insert Operation:

The `INSERT` statement is employed to add one or more rows of data into a table. It is a Data Manipulation Language (DML) statement and is used for manipulating data stored in a database. In the context of the given options, the `Insert` operation indicates the addition of data into the previously created table.

In summary, Option 4, "Create and Insert," accurately represents the SQL operations performed in the provided statements. The `CREATE` statement is used to create a table, and the `INSERT` statement is utilized to insert data into that newly created table. This combination of DDL and DML operations is common when setting up a database schema and populating it with initial data.
