I have to update "table2" from another "table1" located in another database.The "table1" located in another database is updated daily with transactions from the last day.I just want to update "table2" with the new values added into "table1". Rows are not going to be deleted from "table1", It's a historical record of transactions which I want to replay into "table2" because "table2" (in the other database in the same server) will be used for SSAS, for BI. This is what I tried: USE BDID_BI; GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE Transaction Update AS insert [BDID_BI].[dbo].[Transaction] * SELECT * FROM [BDID].[dbo].[hl_transaction] as B WHERE ( SELECT * FROM [BDID_BI].[dbo].[Transaction] WHERE date Another comment, this time by Kenneth Fisher: The above will work but you are making an important assumption, that all of your data was loaded for that date.SQL Server provides the following ways to change data in an existing table.Describes the database application programming interfaces (APIs) that support options for updating data at the current position of a result set.In both cases, you use the SQL statement INSERT INTO to accomplish the task.

INSERT INTO statements are commonly referred to as append queries.

To remove all the records from a table, use the DELETE statement and specify which table or tables from which you want to delete all the records.

After the tables have been created and the data added, changing or updating data in the tables becomes one of the day-to-day processes in maintaining a database.

w=300" data-large-file=" w=443" class="size-full wp-image-106 aligncenter" title="Table2" src=" w=869" alt="Table2" / We need to update the values of column ‘T2Description’ of table T2 which currently have null values ,with the values from table T1(field- T1Description). w=545" class="alignleft size-full wp-image-110" title="Result" src=" w=869" alt="Result" srcset=", w=150 150w,

Note that, here we have 2 common field types i.e, Category and Description. The update script will look like- Result : Result " data-medium-file=" w=300" data-large-file="
