Merge initial gender

in this video of Oracle SQL we will start with the merge statement basically merge statement is used to do the conditional insert or update in a particular table in this particular example I am going to use two tables having these similar structure so let's find out practically the implementation of merge statement so for implementing the merge statement here I go for a couple of table basically I will create a backup or a copy of this employee's table so for doing that I have created another table here named copy EMP basically the structure is similar but I have not taken all the fields because for the demo purpose we are good enough to continue with these number of fields as well now what I will do is first of all I will make a comparison between the employee ID of copy MP table and employee ID of employees table if the employee ID of copy MP table is matched with this table then I will update all these fields that is first-name lastname mobile number and department ID from this one maybe there is a scenario like the employee got updated maybe the last name or the mobile number or the department ID got changed so in order to just make a think I will do a conditional updation in the copy EMP table but if the employee ID in copy EMP is not matched with that of the employees table then I will insert that record using employee's table so let's see how we can do that so first of all let's clear the screen I will start writing it from the top alright so first of all we'll start with the merged keyword all right so merge into then in which particular table you want to merge means make the which table you want to make a copy so that is copy under scope EMP alright if required you can make the alias of this particular table and using vegetable you are making this merge statement first table is the copy MP in which you want to copy the data but from which table that you will specify here that is using employees all right using employees e não é is again the elyes and you will have to specify like using which field you are going to merge as I said like primary key should be there so on a dot employee ID EMP ID is equal to C dot EMP ID means the field names are same that's why I am putting it like that all right so here I specified like which is my main table from which table I am going to take the data and which which is the common field now after that if the primary key fields got matched so when matched ten all right then what all you want to do you want to update so simply write update set and what all fields are available...
