we will create a second (log) table to store the actions taken on that test table using a simple DML trigger. Afterward, we will create three basic triggers in T-SQL code: INSERT, UPDATE, and DELETE. Then
trigger_name を有効または無効にします。 トリガーを無効にした場合、それはまだテーブルに対して定義されています。 ただし、テーブルに対して INSERT、UPDATE、または DELETE ステートメントを実行すると、トリガーが再度有効化されるまでトリガー内のアクションは実行されません。 ALL テ...
A computed column can't be the target of an INSERT or UPDATE statement. Note Each row in a table can have different values for columns that are involved in a computed column; therefore, the computed column might not have the same value for each row. Based on the expressions that are use...
To describe this in more detail: Two database servers with identical tables. One Process writes data into Table 'A' and now I want that a trigger (after insert or after update) writes the same Data into table 'A' on the second database server, with the identical...
For every insert, update, or delete action specified in the MERGE statement, SQL Server fires any corresponding AFTER triggers defined on the target table, but does not guarantee on which action to fire triggers first or last. Triggers defined for the same action honor the order you specify...
DELETE 语句与 REFERENCE 约束"main_id_cons"冲突。该冲突发生于数据库"Stock"，表"db o.test_sub", column 'main_id'。语句已终止。产生这类信息的原因是，你创建了默认的外键约束。默认的就是，为了保证数据的完整性，比如有父子关系的两表。你必须先删除掉子表的数据，让父表的数据，没有子表...
alter TRIGGER [dbo].[TRIGGER_STAGE_INSERT] ON [dbo].[AMGR_Opportunity_Tbl] after insert, update AS BEGIN DECLARE @STAGE VARCHAR (50) SET @STAGE = (SELECT Stage from INSERTED) IF @STAGE IN ('not started','Initial comm','Needs assessment','Proposal submission'...
You must also have space quota in the tablespace in which space is to be acquired in order to use the add_table_partition, modify_table_partition, move_table_partition, and split_table_partition clauses. Additional Prerequisites for Constraints and Triggers...
The INSERT statement inserts rows into a table or view. Inserting a row into a view inserts the row into the table on which the view is based if no INSTEAD OF INSERT trigger is defined for this view. If such a trigger is defined, the trigger is activated instead. ...
