SSIS lookup match output to temporary table (2023)

  I want to update the match data in the destination table and insert data that does not match.
  A few days ago I read an article aboutWWW.SQLservercentral.comdvs
  

  http://www.sqlservercentral.com/articles/Integration+Services+(SSIS)/102924/

  SEE Option 3 (INSERT THEN UPDATE)
  

  
  Where you requested to load match data into temp table and then use temp table to update target table match data...(Performance will be faster compared to OLEDB command.)
  I don't want to use the OLEDB command because the performance is worse and I have approx. 46 million rows coming from the source.

  

  NOTE: I can't create \ am not allowed to create a temp \ fitness table, I want to use the temp ## table so as not to increase the number of tables in my database.
  

  Since the source data has 46 million records and I'm assuming the same large number will be in the destination table to lookup, this approach won't be efficient. I would suggest the following:

  1. load the source data into the raw/stage table.
  2. use the T-SQL MERGE statement to upsert between the final destination table and the raw/staging table.

  POINT 2)
  I can't use t-sql MERGE statement because my source and destination table are in different databases and I don't want to HARDCODE the database name with the table name in T-sql Merge, that's why I'm looking for an SSIS solution.

  Why don't you want to use the database name in the 2 part naming? This is absolutely correct and can be done.

  ENT 1)
  USE RAW\STAGING TABLE: This is my question, how to create a temporary table to load MATCH data coming from SEARCH? So I can use this temporary table to UPDATE THE MATCH DATA in the DESTINATION TABLE.

  I said this may not be efficient because the Find component will have to store all the target records in memory and then identify the delta. This step will be less efficient if the destination table has millions of rcds and LOOK Up is not worth using for me.

  Hola

  in the ssis package you have 2

  1-you can use recordset.

  RecordSet should use variable and

  The variable will be a data type object.

  2- you can use Raw File Destination.

  Hi Rihan,

  from my understanding you have to create the temp table structure first, then you have to load data into the temp table.

  Please try the link below, it might fix the error you are getting.

  Hello Anil,
  Thanks for the reply..

  If you go through my entire thread, I already mentioned that I took the Execute SQL task to create the temporary table and set the required properties like "Keep same connection" and "Delay validation".
  Althoughafter creating temp table ## in EExcute SQL task before data flow taskCan't see temp table ## for LOAD MATCH The data in the temp table came from LOOKUP.
  IMAGE is only to give the idea of ​​requirement..
  Some help?

  May I ask the reason for the temp table? What will you use the data in this temporary table for?

  Have you considered using a Raw file as the destination?

  Since the source data has 46 million records and I'm assuming the same large number will be in the destination table to lookup, this approach won't be efficient. I would suggest the following:

  1. load the source data into the raw/stage table.
  2. use the T-SQL MERGE statement to upsert between the final destination table and the raw/staging table.

  Another problem you will run into when using a destination table is that lookups are deadlocks, this is especially true for large data sets. It would create a lookup cache in memory of the target instead of doing a direct lookup in the table.

  Hello, Harry,
  thanks for the reply
  POINT 1)
  USE RAW\STAGING TABLE: This is my question, how to create a temporary table to load MATCH data coming from SEARCH? So I can use this temporary table to UPDATE THE MATCH DATA in the DESTINATION TABLE.

  POINT 2)
  I can't use t-sql MERGE statement because my source and destination table are in different databases and I don't want to HARDCODE the database name with the table name in T-sql Merge, that's why I'm looking for an SSIS solution.
