INSERT Statement

-

 the presenter covers the INSERT statement in SQL, which is used to add new rows to a table in a relational database. Here's a summary of the key points:

  1. Purpose of INSERT statement: The INSERT statement is part of Data Manipulation Language (DML) in SQL, used to read and modify data in a database. It is specifically used to add new rows of data to a table.


  3. Syntax of INSERT statement: The syntax of the INSERT statement is as follows: INSERT INTO table_name (column1, column2, ..., columnN) VALUES (value1, value2, ..., valueN);

      • table_name: Name of the table where data is to be inserted.
      • (column1, column2, ..., columnN): List of columns into which data will be inserted.
      • (value1, value2, ..., valueN): Corresponding values to be inserted into each column listed.

    2. Inserting one row at a time: Data can be inserted into a table one row at a time by providing values for each column in the VALUES clause.

    3. Inserting multiple rows at once: Multiple rows can be inserted into a table in a single INSERT statement by specifying each row's values separated by commas in the VALUES clause.

    Example: INSERT INTO author (author_id, last_name, first_name, email, city, country) VALUES ('A1', 'Chong', 'Raul', 'RFC@IBM.com', 'Toronto', 'CA'), ('A2', 'Ahuja', 'Rav', 'Rav@xyz.com', 'Delhi', 'IN'); By understanding the syntax and usage of the INSERT statement, users can effectively add new data to tables within a relational database.

Notes on Hiring for Data Science Teams

-
  Unicorn Myth in Hiring: Companies often seek individuals with a myriad of skills for data science roles. Ideal candidates possess domain-specific knowledge, excel in data analysis, and have strong presentation and storytelling skills. However, finding such a "unicorn" is rare, and the focus should shift to other essential qualities. Resonance with Company DNA: The key is to identify applicants who resonate with the company's values and business domain. While analytics skills can be taught, passion for the business is intrinsic and contributes significantly to productivity. Curiosity Matters: Curiosity is a top priority in hiring for a data science team. Candidates should demonstrate a broad curiosity, showing interest in various aspects of their surroundings beyond just data science. Sense of Humor: A lighthearted approach is crucial, as being too serious may hinder collaboration and creativity. A sense of humor aids in navigating challenges and fosters a positive work ...

switch functions

-
  Nested IF Function : The  nested IF  function allows you to perform tests with multiple conditions and return different values based on the results of those tests. It is called “nested” because one IF function is embedded inside another IF function. Syntax of a generic nested IF formula: =IF(condition1, result1, IF(condition2, result2, IF(condition3, result3, result4) ) ) Each subsequent IF function is embedded into the  value_if_false  argument of the previous function. SWITCH Function : The  SWITCH  function is a more compact alternative to nested IF statements. It compares an expression against a list of values and returns the result according to the first matching value. Syntax of the SWITCH function: =SWITCH(expression, value1, result1, [default or value2, result2], ... [default or valueN, resultN]) It has four arguments: expression : The value to compare against the list of values. valueN : A value com...
