GoLang Database Demo

Description:

The following sections provide an overview of essential operations when working with databases in Go, focusing on creating a database, inserting records, and retrieving data.

1. Creating a Database and Table

In Go, the process of creating a database typically involves establishing a connection to the database server using the database/sql package. After successfully connecting, you can execute SQL commands to create a new database and define the structure of your data by creating tables. For instance, you might create a users table with columns for user attributes like id, name, and age. The id column often serves as a unique identifier and is typically set to auto-increment.

2. Inserting Data into the Table

Once the table is set up, you can insert records into it. This is done using parameterized SQL statements to ensure safety against SQL injection attacks. Inserting data usually involves specifying the values for each column in the table. For example, adding new users would require you to provide their name and age, which are then stored in the database.

3. Retrieving Data from the Table

Retrieving data from the database is accomplished by executing SQL SELECT statements. In Go, you can query the database to fetch records and then process the results. This typically involves iterating through the returned rows and extracting data into variables. You can display this data or use it for further processing within your application.

Conclusion

These operations—creating a database and table, inserting records, and retrieving data—form the core of database interactions in Go. Mastering these concepts is crucial for building robust applications that manage persistent data, making them essential skills for developers and relevant topics for technical interviews.
