SQL is a powerful tool that is used to store, manipulate, and retrieve data that is organized in tables. Unfortunately, this same tool is often abused to manipulate the data, which is something that’s very dangerous.

SQL is a powerful tool that can store, manipulate, and retrieve data that is organized in tables. Unfortunately, this same tool is often abused to manipulate the data, which is something thats very dangerous.

A lot of data we store in our databases isn’t all that is there. It could be that there is a lot of data that isn’t all that is there.

For example, lets say we have a database of names. We may want to retrieve all the names that are male. Well, how would we go about this? I dont know. Lets say we dont have a query for this. We can use another database to do the job. This database is called a table.

So, we could use a table to store the names. A table is like a list. The table itself is nothing. it does not contain any sort of records. We could use this table as our data to perform some functions, which would be something like, finding all males in the database, getting a count of how many there are, and so on.

This sounds great, except the tables are not the same. It would be possible to do the same as above, but a lot of things would have to be modified. For example, if we wanted to count how many males there are in our database, we would need to use another table called a sex table. The sex table would contain only one row of data. This would require you to use a different database to retrieve the data.

The problem we have is that sql tables have many of the same columns as those in the data itself. These columns are called foreign keys.

So how do we implement this? First, we need to create a new table using the same name as the table we want to track. Then we should update the definition of the foreign key columns to reference the data we’d be tracking. Finally, we should add a primary key to that table.

This sounds like a lot of work, but in retrospect it really isn’t that bad. The data is already in a table, so we should not have to change the name, but we do need to update the definition of the foreign key columns to reference the data. Plus, if we’re going to get into the details of how to implement foreign keys in a database, I recommend reading about it here.

Also, I would suggest adding a primary key to the tables that will need to be related to the data. The data will have no primary key because it is not related to any tables. The actual definitions of these tables should include the foreign key columns to be used.
