Question
What is the query to fetch the values of specific columns or fields in a table?
Solution
To fetch the values of specific columns or fields in a table, you would use the SQL SELECT statement. Here is a step-by-step guide on how to do it:
-
Start with the SELECT keyword: This keyword is used to select data from a database.
-
Specify the column names: After the SELECT keyword, write the names of the columns you want to fetch. If you want to fetch all columns, use the asterisk (*) symbol.
-
Use the FROM keyword: This keyword is used to specify the table from which you want to fetch the data.
-
Specify the table name: After the FROM keyword, write the name of the table.
Here is an example of a SQL query that fetches the "FirstName" and "LastName" columns from a table named "Employees":
SELECT FirstName, LastName FROM Employees;
If you want to fetch all columns from the "Employees" table, you would write:
SELECT * FROM Employees;
Remember to end your SQL query with a semicolon (;).
