SQL Server 2012 :: Data Transfer From Staging Table Into Main Table
Jan 14, 2014
What is the best way to transfer data from the staging table into the main table.
Example:
Staging Table Name: TableA_satge (# of rows - millions)
Main Table Name: TableA_main (# of rows - billions)
Note: Staging table may have some data same as the main table.
Currently I am doing:
- Load data into staging table (TableA_stage)
- Remove any duplication of rows from the staging table (TableA_stage)
- Disable all indexes on main table (TableA_main)
- Insert into main table (TableA_main) from staging table (TableA_stage)
- Remove any duplication of rows from the main table using CTE (TableA_main)
- Rebuild indexes on main_table (TableA_main)
The problem with the above method is that, it takes a lot of time and log file size grows very big.
I am trying to insert bulk data into main table from staging table in sql server 2012. If any error comes, this total activity is rollbacked. I don't want that to happen. I want to know the records where ever the problem persists, and the rest has to be inserted.
I'm trying to use Excel in SSIS to import the data from spreadsheet to a staging table. The package runs well from the web server using SSMS. But when I deploy and try to execute the package, I'm getting the below error. I've a question, whether I've to install the AccessDatabaseEngine driver in SQL database server or the web server where I'm executing the SSIS?
Error: The requested OLE DB provider Microsoft.Jet.OLEDB.4.0 is not registered. If the 64-bit driver is not installed, run the package in 32-bit mode.
We are designing a Staging layer to handle incremental load. I want to start with a simple scenario to design the staging.
In the source database There are two tables ex, tbl_Department, tbl_Employee. Both this table is loading a single table at destination database ex, tbl_EmployeRecord.
The query which is loading tbl_EmployeRecord is, SELECT EMPID,EMPNAME,DEPTNAME FROM tbl_Department D INNER JOIN tbl_Employee E ON D.DEPARTMENTID=E.DEPARTMENTID.
Now, we need to identify incremental load in tbl_Department, tbl_Employee and store it in staging and load only the incremental load to the destination.
The columns of the tables are,
tbl_Department : DEPARTMENTID,DEPTNAME
tbl_Employee : EMPID,EMPNAME,DEPARTMENTID
tbl_EmployeRecord : EMPID,EMPNAME,DEPTNAME
How to design the staging for this to handle Insert, Update and Delete.
I am having one store procedure which use to load data from flat file to staging table dynamically. everything is working fine.Staging_temp table have single column.All the data stored in that single column below is the sample Data.
I'm attempting to load some data into an explicit hierarchy in MDS 2012 via the staging table and struggling with the HierarchyName field. Specifically I'm loading data into stg.[Entity Name]_Consolidated and using the exact name of the explicit hierarchy I've set up in the front end web application.
Originally my hierarchy was labelled "Reporting Hierarchy" and when loading the data into staging using this name then running the batch from the Import Data screen I can see the error message "Error - The HierarchyName is missing or is not valid.". I've checked the table mdm.tblHierarchy and can see that the name there is exactly as it was in the staging table and have since renamed the hierarchy as "Reporting_Hierarchy" with the same results.
In my ETL job I would like to truncate stg table but before truncating stging table, I want to make sure that all the records are inserted in the data model. The sample is as below
create table #stg ( CreateID int, Name nvarchar(10) ) insert into #stg select 1, 'a' union all select 2, 'b' union all
[Code] ....
How can I check among these tables and make sure that all values are loaded into the data model and the staging table can be truncated.
where including/excluding a single column in an empty staging table would influence a resultset returning from distributed query? Both servers are SQL Server 2012. Nothing special about the staging table. It contains 12 columns with a mixture of INT and NVARCHAR(256) columns. In one case I exclude the column and the query returns in 17 seconds. When I include it the query does not return. Excluding the INSERT INTO the staging table and query returns in 17 secs with and without the column.
I am extracting source data which is in txt fille to OLE DB destination. But data of each day I want to save in different staging table. For Eg; tblProduct20081206, tblProduct20081207. How can it be done. I have seen lots of posting and script when destination is Txt. I want to use same table for staging but want to create different table for each day with adding date extension.
I am working on an HR project and I have one final component that I am stuck on.
I have an Excel File that is loaded into a folder every month.
I have built a package that captures the data from the excel file and loads it into a staging table (transforming a few bits of data).
I then combine it with another table in a view.
I have another package that loads that view into a Master table and I have added a Slowly Changing Dimension so that it only updates what has been changed. (it’s a table of all employees, positions, hire dates, term dates etc).
Our HR wants to have this data in a report (with charts and tables) and they wanted it to be in a familiar format. So I made a data connection with Excel loading the data into a series of pivot tables.
I have one final component that i cant seem to figure out. At the end of every year I need to capture a count of all Active Employees and all Termed employees for that year. Just a count.
The data is in one table labeled [EEMaster]. To test the count I have the following.
SELECT COUNT([PersNo]) AS HistoricalHC FROM [dbo].[EEMaster] WHERE [ChangeStatus] = 'Current' AND [EmpStatusName] = 'Active'
this returns the HistoricalHC for 2013 as 418.
SELECT COUNT([PersNo]) AS NumbOfTermEE FROM [dbo].[EEMaster] WHERE [ChangeStatus] = 'Current' AND [EmpStatusName] = 'Withdrawn' AND [TermYear] = '2013'
This returns the Number of Termed employees for 2013 as 42.
I have created a table to report from called [dbo.TORateFY] that I have manually entered previous years data into.
Hello, Maybe anyone have done that before? I have table where i store SOURCE_TABLE_NAME and DESTINATION_TABLE_NAME, there is about 120+ tables. i need make SSIS package which selects SOURCE_TABLE_NAME from source ole db, and loads it to DESTINATION_TABLE_NAME in destination ole db.
I made such SSIS package. set ole db source data access mode to table or view name variable. set ole db destination data access mode to table or view name variable. set to variables defoult values (names of existing tables) but when i loop table names is changed, it reports error, that can map columns, becouse in new tables is different columns.
I have two database(MYDB1 , MYDB2) on two different server's(SERVER1 , SERVER2) . I want to create an store procedure in MYDB1 on SERVER1 and get some data from a table of MYDB2 on SERVER2. How can i do this?
Hi, Is this anyway to finding updated/ deleted recored using anyother data flow transformation tasks without using sql task. Can find the new records using merge join task.
Is there better way to merge master table using staging table?
We need to Insert/Update a Fact Table from staging Table. currently we are using a SP which update Fact Table for Each region. this process is schedule, every 5 min job is run and Update fact table.but time of Insert and Update too long from staging to Fact, currently we are using merge statement for Insert and update.in my sp we are looping number how many region we need to update and at a time single Region we are updating using while loop in current SP.
Hi I have a production table in SQL Server 2005 that has approx 500,000 records---every 6 hours this table needs to be truncated and filled
The basic SSIS package uses a script compentant and imports the data into a staging table which has the same structure as the production table. I have a final Execute SQL Task that Truncates the production table and does a Insert into production-select * from stage table.
Takes around 30 seconds to run this last Execute SQL Task--problem is there is a risk that our webservice will query this table during the Execute SQL Task and return incorrect results.
Q1: In this last Execute SQL Task if I used a BEGIN TRANSACTION and COMMIT TRANSACTION; will this be any quicker ?
Q2: In this last Execute SQL Task- would it be better to use a RENAME TABLE technique in TSQL--any code examples ??
Q3:Is there any way in TSQL I can compare EVERY FIELD in two tables ie Stage and Production which have identical data structures and figure out a way to update only the records that changed? Is SQL Server Replication the best way to do this
After the staging_temp data gets inserted into main table.my probelm is to handle such a file where number of columns are more than the actual table.
If you see the sample rows there are 4 column separated by "¯".but actual I am having only 3 columns in my main table.so how can I get only first 3 column from the satging_temp table.
Is it possible/advisable when transfering very large amounts of data from server to server to: trasnfer the data to a new table first second alter new table adding indexes, defaults, ets based on original table
if it is what flow item would be used to transfer/alter the indexes and defaults?
I'm very new to ssis so the more detail you can give the better.
Hallo i have two tables, MainTable and MainTableAudit: the second one keeps DML auditing via triggers. I'm trying to build a query to highlight changes occurred to fields between the MainTable record and its audited records in MainTableAudit, for example, let's suppose i entered an item with some wrong attributes, and edited it three times: MainTable record contains the latest and current version ID002|Hitchhikers Guide to the Galaxy|Sci-fi|240 pages MainTableAudit contains edited ID002 versions ID002|Hitchhikers Guide to the Galaxy|Sci-fi|232 pages|2006-07-08 08:32:12 ID002|Hitchhikers Guide to the Galaxy|Sci-fi|212 pages|2006-05-08 10:54:02 ID002|Hitchhikers Guide to Galaxy|Sci-fi|222 pages|2006-07-04 11:42:16
I would like to build a report like this: first insertion: Hitchhikers Guide to Galaxy|Sci-fi|222 pages modified on 2006-07-04 11:42:16: field "Title" changed from "Hitchhikers Guide to Galaxy" to "Hitchhikers Guide to the Galaxy", field "PageNo" changed from "222" to "212" modified on 2006-05-08 10:54:02: field "PageNo" changed from "212" to "232" modified on 2006-07-08 08:32:12: field "PageNo" changed from "232" to "240" current version: Hitchhikers Guide to the Galaxy|Sci-fi|240 pages
i'd prefer to use T-SQL and keep all into a single place (a view or storedprocedure), or at least to use reporting services; btw i would like to avoid coding web pages or hosted applications.
I need to transfer data from one table to another.I will be using the SQL Query Analyzer to do this.This is not a simple transfer of data to the same structured tables.These tables are completely different, for the most part.For instance, I will be selecting certain fields of one table.....SELECT fldOne, fldTwo FROM someTableI need to take this information, one row at a time and input it into a different type table.So, something like this to insert into the other table...INSERT INTO otherTable( fld1, fld2) VALUES( value1, value2 )I've looked around for a sample to achieve this, but may have overlooked it?Anyone have a link to show this or a quick sample?Thanks all,Zath
I'm trying to import the contents of a CSV file into a staging table that I've created in SQL server 2005. To perform the import I have used the BCP utility with the use of a BCP format file.
The problem I'm having is that the data in some of the fields in the csv file are longer than the length of the corresponding field in my staging table. So when I try to import I get the following error:
[Microsoft][ODBC SQL Server Driver]String data, right truncation
And the record with the error does not import.
My question would be, is there a way of telling BCP to trim the data before importing into the staging table? Could I somehow specify in the BCP file to trim the data before importing or is there a switch that i can specify in the BCP command which tells BCP to trim data to the length of the destination column.
If it helps I'm using the command below to run BCP.
for bcp in, 1. use fixed length format file or delimitered file? 2. table w/o index including primary key? 3. sort the text file before bcp in (will it speed up indexes creation after data uploading?)
which pt will or will not improve the overall bcp in processing?
Just requesting for help about transferring data from one table to another.
For example: In Table1, there are 3 columns: Col1 Col2 Col3 T1C1R1 T1C2R1 T1C3R1 T1C1R2 T1C2R2 T1C3R2 T1C1R3 T1C2R3 T1C3R3 T1C1R4 T1C2R4 T1C3R4
In the target Table2, Col1 should be a string constant,e.g. "A" and Col2 from Col1 of T1 and Col3 from Col2 of T1: Col1 Col2 Col3 A T1C1R1 T1C2R1 A T1C1R2 T1C2R2 A T1C1R3 T1C2R3 A T1C1R4 T1C2R4
I found something like "INSERT INTO TABLE2 (COL1, COL2, COL3) SELECT COL1, COL4, COL7 FROM TABLE1" but this code requires colomn one of the table 1 be selected as well but the column one of the target table 2 requires a constant string.
I also tried this but doesn't seem to work:
Code Block
dtTable1 = ds.Tables(0) ' Table1 bSQL.Length = 0 For Each dr In dtTable1.Rows bSQL.Append("INSERT INTO Table2(Col1, Col2, Col3) ") bSQL.Append(" VALUES(") bSQL.Append("'" & "A" & "',") ' Constant for column 1 of Table2 bSQL.Append("'" & dr(0).ToString() & "',") ' All data in the first column of Table1 bSQL.Append("'" & dr(1).ToString() & "')") ' All data in the second column of Table1
i have two database on my sql server,, and i m trying to create a report in whch both database need to share their data.. @ the moment what i did, i simply create a view on one database to access the table of other database.. but is anyone has a better idea how can i transfer data from one database to another database... i think if i do with creating temp table that might resolve this problem.. but when it comes on another server of another database , how can i will do this ... please give me any idea if u got my point .

I have a flat file with columns from a geographical hierarchy such as:
Country Zone State County City Store Sub Store , etc.
The file also has data columns for months to the right of the above columns such as:
Jul Aug Sept ......... basically 25 of these columns for two years' data for one product and another set of 25 columns for another kind of product. A typical record in the file looks like:
Country Zone State County City Store Substore
USA Southeast FL Hillsborough Tampa walmart Fletcher
I need to upload this data into a staging table in SQL Server 2005 using SSIS, I created a table with the geographical hierarchy columns but am trying to figure out a way to load the monthly data. I can create 50 columns for the 50 months ( 25 months for each product) but that would be very crude.
Is there a better way of inserting data from this flat file into a destination table? I need all the data in the staging table in one upload.
Is there a way to transfer ntext data from one table to another?I tried thisUPDATE [projects]SET [description] = (SELECT [description_ntext] FROM [table] WHERE[id]=1)WHERE [id_project] = 1;and thisDECLARE @DESCRIPTION ntextSET @DESCRIPTION = (SELECT [bids].[bid_conditions] FROM [bids],[projects] WHERE [bid_accepted_id] = [bids].[id_bid] AND [id_project] =@ID_PROJECT);UPDATE [projects]SET [description] = @DESCRIPTIONWHERE [id_project] = 1;none of those work in MSSQL2K,error reported is "The text, ntext, and image data types are invalidfor local variables."
I am newbie to MDS of SQL,want to know how we can transfer tables from two different SQL Databases to MDS.Suggest me the steps to proceed with any examples.
