Here are examples of SQL statements for SELECT, INSERT, UPDATE, and DELETE operations in Microsoft SQL Server:
Microsoft SQL Server SELECT Statement
The SELECT statement is used to retrieve data from one or more database tables.
SELECT column1, column2, ...
FROM table_name
WHERE condition;
Microsoft SQL Server INSERT Statement
The INSERT statement is used to insert new rows of data into a table
INSERT INTO Customers (FirstName, LastName, Email)
VALUES ('John', 'Doe', 'john.doe@example.com');
Microsoft SQL Server UPDATE Statement
The UPDATE statement is used to modify existing data in a table.
UPDATE Customers
SET Email = 'newemail@example.com'
WHERE CustomerID = 1;
DELETE Statement
The DELETE statement is used to remove rows of data from a table.
DELETE FROM Customers
WHERE CustomerID = 1;
Please note that the examples above are basic templates, and you would need to modify them based on your specific table structure, column names, and conditions. Additionally, it’s important to exercise caution when performing DELETE or UPDATE operations as they can permanently modify or remove data from your database. Always make sure to have proper backups and double-check your conditions before executing such statements.
