SQL Query: Drop Table if Exists
The code snippet you provided checks if the table named 'tablename' exists, and if it does, it executes the DROP TABLE statement to delete it. This code can be used to ensure that the table is dropped before creating a new one.
IF OBJECT_ID('tablename', 'U') IS NOT NULL DROP TABLE tablename;
In this code:
- The IF OBJECT_ID('tablename', 'U') IS NOT NULL condition checks if the table named 'tablename' exists.
- If the condition is true (indicating that the table exists), the DROP TABLE statement is executed to delete the table.
Please note that you should replace 'tablename' with the actual name of the table you want to check and drop if it exists.
