01:45:00 In this video, we learn how to use the having keyword with group by to filter the data after it has been aggregated. We use count and count is simply the sum of the number of people in each country. We use bigger than to filter out countries that have a count greater than a certain value.
01:50:00 In this video, the narrator explains how to use various aggregate functions in PostgreSQL. These functions can be used to compute a single result from a set of input values. The most common aggregate functions are count, max, and min. The narrator also explains how to use the stat function, which computes various statistics from a dataset.
01:55:00 In this video, a full course on PostgreSQL, the max and min functions are explained, as well as the average function. Finally, the sum operator is introduced.

02:00:00 - 03:00:00

This video is a tutorial on how to use PostgreSQL operators for arithmetic. The video starts with a data set and demonstrates how to sum, aggregate, and perform basic calculations with the PostgreSQL operators. It then goes on to explain how to use dates with PostgreSQL, and how to add a primary key to a table. Finally, it covers how to use indexes and constraints to improve table performance.

02:00:00 This video teaches beginners how to use the PostgreSQL operators for arithmetic. The video starts with a data set and demonstrates how to sum, aggregate, and perform basic calculations with the PostgreSQL operators.
02:05:00 In this video, the arithmetic operators for PostgreSQL are explained. These operators are straightforward to use and can be used to calculate results in a similar way to other languages.
02:10:00 In this chapter, the author teaches how to handle nulls with PostgreSQL by using the coalesce keyword.
02:15:00 In this video, we learn how to use the PostgreSQL coalesce keyword to specify a default value for a column when the value is no. We also learn how to tackle division by zero using this keyword.
02:20:00 This video teaches how to use dates with PostgreSQL. The first function gives the actual date, and the other two give the time and the interval.
02:25:00 The "Learn PostgreSQL Tutorial - Full Course for Beginners" video introduces the concept of dates and date arithmetic, then demonstrates the age function, which allows users to extract specific values from a date.
02:30:00 In this video, the instructor explains how to use primary keys in a table. The first thing that he wants to do is to describe the person table, which has a primary key ID of one. Then he inserts a person with the same ID as Alfredo, and the table fails because the ID is already in use. He drops the constraint and the table works.
02:35:00 In this video, the author demonstrates how to add a primary key to a table using the ALTER TABLE command. The command requires that the table be declared with a constraint name and that the constraint be unique for every row. If the constraint is not unique, the command will fail.
02:40:00 The unique constraint is a constraint that allows you to have unique values for a given column. It is useful when you need to prevent duplicate values for a column. In this video, you will learn how to add the constraint and how to use it.
02:45:00 This video teaches beginners how to use PostgreSQL to create and use indexes and constraints. The first part of the video covers how to create a table and insert data. The second part covers how to use indexes and constraints to improve table performance.
02:50:00 This video explains how to use PostgreSQL's check constraint feature to ensure that only specific values are allowed in a column.
02:55:00 In this tutorial, the author explains how to delete records from a table using the delete command. The command can be executed from either a script or a SQL file. The author also shows how to filter the deletion by using the where clause.

03:00:00 - 04:00:00

This video tutorial explains how to use the PostgreSQL update command to update a table's data. The command requires a where clause to avoid updating or modifying the entire table. The presenter also teaches how to use the on conflict keyword to perform updates on a row that has a conflict.

03:00:00 In this video, the update command is explained and how it works. The where clause is used to filter rows to be updated, and the condition is used to specify which rows to update.
03:05:00 This video tutorial explains how to use the PostgreSQL update command to update a table's data. The command requires a where clause to avoid updating or modifying the entire table.
03:10:00 In this video, the presenter teaches how to use the on conflict keyword to perform updates on a row that has a conflict. When using this keyword, you first need to determine the current value of the row with the conflict and then use the set command to set the value of the excluded dot email to the new value.
03:15:00 In this video, the presenter teaches how to create a relationship between two tables in PostgreSQL. A relationship is a column that references a primary key in another table, and in order for this to work, the types have to be the same. The syntax goes like this: car underscore ID, that type.
03:20:00 In this tutorial, a beginner's guide to PostgreSQL, the author drops two tables and then creates a new table with a foreign key to the old one. The author then executes the table creation from a file, checks for errors, and sees that the table was created successfully.
03:25:00 In this video, the presenter teaches how to assign two cars to two people and how to use a foreign key constraint to ensure that the cars are assigned only when there is a relation between the person and car tables.
03:30:00 This video teaches how to perform an inner join between two tables, using the PostgreSQL SELECT statement. The video covers how to select every column from both tables, and specify the table to join in parentheses.
03:35:00 This video explains how to perform a left join between two tables, which includes returning all the records, even if there is no matching row in the other table.
03:40:00 In this tutorial, we learn how to delete records with foreign keys, and how to avoid errors caused by still-referenced records.
03:45:00 This video teaches how to delete data from a PostgreSQL table using different techniques, including deleting the table itself if no foreign key constraint exists, or updating the table's ID to remove the foreign key constraint first.
03:50:00 This video explains how to generate a CSV file from a PostgreSQL table with the help of the big integer data type. You can use sequences to manage the IDs of newly inserted rows.
03:55:00 In this video, we learn about PostgreSQL extensions, which are functions that can add extra functionality to the database. We also learn how to use IDs, which are universally unique identifiers, with Postgres.
