This video is going to be all about the process of updating the existing data present in the table. How to update the values in the table is precisely explained over here. We are using sqlite3 and we are working on the IPL2020 database which has been already created. The update helps in adding, changing, and deleting the information present in the existing record.
Syntax:
var_name.execute(“UPDATE TABLE_NAME SET COLUMN1= “VALUE1”… WHERE CONDITION”)
Note that the WHERE clause is very important. It specifies which record is to be updated. If the WHERE clause is avoided then each entry in the table gets updated.
Also, we need to use the SELECT query to display the values which we have just updated.
Syntax:
var1_name = var_name.execute(“SELECT * FROM TABLE_NAME”)
where * means all the values.
