FROM - In the FROM clause, re-specify the table you want to update.SET - Next, specify the new value for the column of the updated table.(Users can also use the SQL alias instead of the table name). UPDATE - First, specify the table name that you want to update.A single update statement cannot be used to update multiple columns from different tables.DBAs cannot update multiple tables simultaneously using SQL Server UPDATE JOIN.SQL Server UPDATE JOIN is also known as a " cross-table" update.Using SQL Server UPDATE JOIN, you can Update a table by joining two or more tables together. With the help of UPDATE JOIN (Cross-Table Update), a DBA can perform various tasks such as updating the main table using an audit table (another table) in case of any mismatch, updating records in the main table based on multiple tables, etc. A DBA may update all or some records based on the condition specified in the WHERE clause. SELECT * FROM OnkarSharma_UPDATE_JOIN.tbl_MenuĭBAs use update queries in SQL Server to update an existing row in a table. SELECT * FROM OnkarSharma_UPDATE_JOIN.tbl_OrderItemsģ) To get the data from the "tbl_Menu" table, use the following query.
SELECT * FROM OnkarSharma_UPDATE_JOIN.EmployeeĢ) To get the data from the "tbl_OrderItems" table, use the following query. Let's check our following tables by using the following queries.ġ) To get the data from the "Employee" table, use the following query. Next, you can insert data to these tables using the SQL INSERT statement or by adding data direct to the tables in SSMS. OrderStatus TINYINT NOT NULL, - => OrderStatus: 4: Cancelled 3: Pending 2: Processing 1: Completedĭiscount DECIMAL(5, 2) NOT NULL DEFAULT 0, OrderId INT IDENTITY (108, 1) PRIMARY KEY, PRINT 'New Database ''OnkarSharma_UPDATE_JOIN'' Created'ĮmployerID BIGINT NOT NULL DEFAULT 228866,
Copy this query and execute it in Query Explorer or the command line. The following SQL query creates a new database and a few tables. You can still do this step if you already have an existing database.
