Date datetime, my. Time datetime). Now, to ease my SQL statements (and for performance reasons) I want to make sure the column my. Date always has the time set to '0. Time column always has the date set to '1/1/1. Transact-SQL Syntax Conventions. Syntax-- SQL Server Syntax -- Trigger on an INSERT, UPDATE, or DELETE statement to a table or view (DML Trigger) CREATE [ OR ALTER. I want to know how can I use UPSERT or in other words UPDATE if records exists Else enter new record operation in SQL Server using one statement? This example shows. SQL Server: Why is TRUNCATE TABLE a DDL and not a DML operation and difference from DELETE. First let's look at the difference assuming we want to delete the whole.You can do this in a regular trigger but an "INSTEAD OF" trigger would work even better. It helps avoid dealing with trigger recursion that you would otherwise experience since you will be modifying the underlying table. This type of trigger overrides the action of the statement that triggered it. Instead, it just executes the code inside of the trigger. Here is a sample code that stores the date and time in the format you specified, it creates a table and two INSTEAD OF triggers, one for inserts and the other one for deletes: CREATE TABLE [dbo] . My. Table] (. [ID] [int] IDENTITY (1,1) NOT NULL PRIMARY. Date] [datetime] NOT NULL. Time] [datetime] NOT NULL. My. Table. Insert. Trigger ON My. Table. INSTEAD OF INSERTASBEGINSET NOCOUNT ON. INSERT INTO My. Table. Date, my. Time). SELECTCONVERT(VARCHAR(1. Date, 1. 01). DATEADD (DD, - CAST (my. Time AS FLOAT), my. Time). CREATE TRIGGER dbo. My. Table. Update. Trigger ON My. Table. INSTEAD OF UPDATEASBEGINSET NOCOUNT ON. SET my. Date = CONVERT (VARCHAR(1. Inserted. my. Date, 1. Time = DATEADD (DD, - CAST(Inserted. Time AS FLOAT). Inserted. Time). FROM Inserted, My. Table. WHERE Inserted. ID = My. Table. ID. You can now run these statements and verify that the date and time are stored as you wanted: INSERT INTO My. Table. SELECTGETDATE (), GETDATE (). SELECT * FROM My. Table. SET Mydate = GETDATE (). Time = GETDATE (). SELECT * FROM My. Table. The code that removes the time part from my. Date is fairly straightforward - - when you convert from datetime to varchar(1. The code that sets the my. Time column to '1. I am using the DATEADD function to subtract number of days between the base date of '1. Date column. I can do this because internally dates are stored as integers. The numeric value of '1. This code gives you the number of days between today and '1. SELECTDATEDIFF (DD, '1. Deprecated Database Engine Features in SQL Server 2. THIS TOPIC APPLIES TO: SQL Server (starting with 2.

These features are scheduled to be removed in a future release of SQL Server. Deprecated features should not be used in new applications. For SQL Server 2. Deprecated Database Engine Features in SQL Server 2. You can monitor the use of deprecated features by using the SQL Server Deprecated Features Object performance counter and trace events. For more information, see Use SQL Server Objects. The value of these counters are also available by executing the following statement: SELECT * FROM sys. WHERE object_name = 'SQLServer: Deprecated Features'. Features Not Supported in the Next Version of SQL Server The following SQL Server Database Engine features will not be supported in the next version of SQL Server. Do not use these features in new development work, and modify applications that currently use these features as soon as possible. The Feature name value appears in trace events as the Object.
