If you want to insert a lot of data into a database with SQL Server, then you can use a Stored Procedure. The procedure needs to be created on the database machine and not the server you are running your application from. There is no Command Line or other way for this procedure to connect via the network. For example, if you are running your application from your local machine, within Visual Studio. This means that you have to have a remote connection to the database first such as using SQL Server Management Studio (SSMS) or SQL Query Analyzer.
Update Multiple Rows In Sql Server With Different Values
UPDATE [dbo].[tblMain] SET [Level1] = ‘New Level’ WHERE id = 1;
SQL Update Multiple Rows By ID
UPDATE [dbo].[tblMain] SET [Level1] = ‘New Level’ WHERE id = 1;
SQL Update Multiple Columns
UPDATE table SET col1 = ‘foo’ WHERE id = 1;
UPDATE table SET col1 = ‘foo’ WHERE id = 2;
In this tutorial, we will learn how to update multiple rows in SQL Server with different values.
To update multiple rows in SQL Server, we need to use UPDATE statement with SET clause and specify the columns that we want to update.
We can also use the WHERE clause to filter the rows that need to be updated.
Update Multiple Rows With Different Values
Updating multiple rows with different values is not something that you can do with a single UPDATE statement, but it’s possible to achieve this task in SQL by using subqueries. The following example demonstrates how to update multiple rows with different values:
INSERT INTO [dbo].[tblEmployee]([Name], [Age]) VALUES(N’David’, 29), (N’Donald’, 35), (N’Michael’, 28);
SELECT * FROM tblEmployee;
ID NAME AGE
1 David 29
2 Donald 35
3 Michael 28
UPDATE table_name SET column1 = value1, column2 = value2, … where condition;
In this example, we are updating all the rows in a table. Let’s say that you want to change the salary of all the employees whose salary is less than 15000. You can use the following query to update multiple rows in SQL Server:
UPDATE Employee SET Salary = 15000 WHERE Salary < 15000;
UPDATE is a DML statement that updates the existing records in a table.
Out of all the DML statements, UPDATE is the most commonly used. That’s because it’s used to update the existing data in a table.
UPDATE
The UPDATE statement is used to modify existing records in a table. The basic syntax of the UPDATE statement is:
UPDATE table_name SET column_name1 = value, column_name2 = value,… WHERE condition;
In this tutorial, I will show you how to update multiple rows in SQL Server with different values. I will also share with you some useful tips on how to update multiple columns and how to update multiple rows from different tables at once.
Update Multiple Rows By Id
Let’s assume that we have a table named Employee, which contains employee details such as ID, Name, Age and Salary. We want to update their salaries based on their ages. So our database would look something like this:
ID Name Age Salary 1 John 25 5000 2 Mary 26 7000 3 Sara 27 8000 4 Sam 28 9000 5 Ana 29 10000 6 Jane 30 11000 7 Mark 31 12000 8 Tommy 32 13000 9 Bob 33 14000
Now let’s say we want to increase the salary of all employees whose age is greater than 25 by 1000$. We can use an UPDATE statement like so:
SQL Server has two different syntaxes to update a table. These two methods are INSERT and UPDATE. The difference between these two is that in INSERT, you can add new rows, while in UPDATE, you can update existing rows.
INSERT INTO table_name (column1, column2) VALUES(value1, value2).
UPDATE table SET col1 = ‘value1’, col2 = ‘value2’ WHERE id = ‘id’
Explanation:
UPDATE table SET col1 = ‘value1’, col2 = ‘value2’ WHERE id = ‘id’
The first part of the statement tells SQL Server to update the rows in the table. In this case, all rows in the table are updated.
We can also specify which rows are updated by specifying a WHERE clause. For example:
UPDATE products SET price = 100 WHERE categoryId = 1
This will update all products in category 1 with a price of 100.
The above syntax is used to insert new values into a table. The table name and column names are separated by commas. The values are surrounded by parentheses and separated by commas as well.
UPDATE table_name SET column1 = ‘value1’, column2 = ‘value2’ WHERE some_condition= true .
The above syntax is used to update existing values in a table. In this case, we are updating the value of one or more columns based on some condition using the LIKE operator or an IN statement. You can also use other operators such as BETWEEN and NOT IN which we will cover later in this article.
UPDATE syntax:
Updating multiple rows in SQL Server can be accomplished by using an IN clause with the WHERE and SET operators. The following example updates three rows in the sales table where the product name is equal to ‘Shoes’:
SELECT * FROM sales WHERE product_name = ‘Shoes’ UPDATE sales SET quantity = 100 WHERE product_name = ‘Shoes’ SELECT * FROM sales WHERE product_name = ‘Shoes’ UPDATE sales SET quantity = 200 WHERE product_name = ‘Shoes’ SELECT * FROM sales WHERE product_name = ‘Shoes’ UPDATE sales SET quantity = 300.
In this tutorial, we will learn how to update multiple rows in SQL Server by ID. When you have a table with a primary key and you need to update multiple rows but only for one value, you can use the UPDATE statement.
The following example updates the email address of all employees whose last name is “Smith” using a WHERE clause:
UPDATE Employee SET EmailAddress = ‘new@email.com’ WHERE LastName = ‘Smith’;
UPDATE statement is used to update the existing records in the table.
UPDATE SQL is a database programming statement used to modify the data in a table. It can be used to insert, update, or delete data from existing records in a table.
SQL UPDATE Syntax
The general syntax of an UPDATE statement is as follows:
UPDATE [table_name] SET [column1]=value1,[column2]=value2,…[columnN]=valuen WHERE [condition];
Here are some examples of UPDATE statement:
UPDATE products SET price = price * 1.5 WHERE id IN (1, 2);
UPDATE products SET price = price * 1.5 WHERE id NOT IN (3, 4);
UPDATE products SET price = price * 1.5, quantity = quantity + 1 WHERE id IN (1, 2);
UPDATE products SET price = price * 1.5, product_name = ‘New Brand’ WHERE id IN (1, 2);
