Sql server trigger if updating online dating games
If the Update() returns TRUE even the value of Name is not changed, do I have to compare the value in the inserted and deleted virtual tables to find out if the value is really changed?
If you want to do actions based on whether the values are changed you're going to need to use SQL and compare the inserted and deleted rows.
Here's an approach to keeping a last updated column in sync: --/* IF OBJECT_ID('dbo.tgr_tbl Sample_Insert Update', 'TR') IS NOT NULL DROP TRIGGER dbo.tgr_tbl Sample_Insert Update GO --*/ CREATE TRIGGER dbo.tgr_tbl Sample_Insert Update ON Sample AFTER INSERT, UPDATE AS BEGIN --Trigger IF UPDATE(Sample Name) BEGIN UPDATE tbl Sample SET Sample Name Last Changed Date Time = CURRENT_TIMESTAMP WHERE Sample ID IN (SELECT Inserted. Sample Name, '') Note that the IF UPDATE() check is used to help improve the efficiency of the trigger for when the Sample Name column is NOT being updated.
Qty To Repair - it only tests if column appears in update list, and is always true for inserts.
Qty To Repair ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified] ON [dbo].[SCHEDULE] AFTER UPDATE AS BEGIN SET NOCOUNT ON; UPDATE SCHEDULE SET modified = GETDATE() , Modified User = SUSER_NAME() , Modified Host = HOST_NAME() FROM SCHEDULE S INNER JOIN Inserted I ON S.
Qty To Repair Column to new value, if new value equal to old value in one or multi row, solution 1 update all updated row in Schedule table but solution 2 update only schedule rows that old value not equal to new value.
Qty To Repair IF UPDATE (Qty To Repair) begin INSERT INTO tmp Qty To Repair Changes (Order No, Part Number, Modified Date, Modified User, Modified Host, Qty To Repair Old, Qty To Repair New) SELECT S. Part Number, GETDATE(), SUSER_NAME(), HOST_NAME(), D. The T-SQL for creating this trigger is shown below.It is very important to include the INNER JOIN to the INSERTED table so that only the updated rows are affected. ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified] ON [dbo].[SCHEDULE] AFTER UPDATE AS BEGIN SET NOCOUNT ON; IF UPDATE (Qty To Repair) BEGIN UPDATE SCHEDULE SET modified = GETDATE() , Modified User = SUSER_NAME() , Modified Host = HOST_NAME() FROM SCHEDULE S INNER JOIN Inserted I ON S. It does not check if column value has changed, because you might have more than one row, where some values have changed and some have not. If I comment out the where then the modified information is updated in every case.Tags: Adult Dating, affair dating, sex dating
