I'm new to SSIS, I'm trying to extract data from an Excel file into Postgres database,
I have tried a small file example that contains only one String column "column1" with 3 lines:
ab
ac
abb
And I have created one table with one column in Postgres
I have created a task with excel source, and ODBC destination the connection worked good I can see the data, but when I execute the task I get empty strings in the database.
I don't know what is the problem can anyone help?
PS: I'm using visual studio 2019, Postgres 9.4 with Pgadmin 3 and I imported Excel as 96-2003
I used OLEDB connection instead of ODBC connection and it worked

I have an excel sheet with a single workbook with data in it. The data is around 1000 rows and 50 columns. I need to import these data to an Oracle DB every week. Here comes the problem, the columns in the sheet belongs to different tables with some columns go in multiple tables. I use SQL Developer V.18.1.0.095. Thanks in advance for the help.
Note: I created a temp table and copied all data to it, then wrote the query to push each column to its respective tables. But, I feel its complex and think it won't work. Is there any better way.
PL/SQL Developer has special tool for tasks like this, calls ODBC Importer (Menu 'Tools'-> ODBC Importer).
For use it you have to set Excel File in USER / System DSN field and your domain user and password, and push Connect after.
After connection developer will ask you path of excel file, and after you can create table in heiborhood tab for your dataset.
Or, you can use sql loader. Ask google how to. It's easy.
I am trying to open a file that i exported from TOAD which has 1.4 million records. It has 4 columns.
I tried opening the file in notepad++, deleting half records there and copying them into other file and saving them. But when i open the 2 files in excel, all the columns are combined as one column.
Could someone give me a solution on how to divide the 1.4million records excel file into 2 files without messing up the columns or data.
If you are married to Excel, skip Toad completely and bring the data in directly with MS Query.
If this isn't SQL Server, you will need to set up an ODBC connection, and from there you can bind the query to the spreadsheet as follows:
From the "Data" tab, select "From Other Sources"
Pick SQL Server if it's SQL Server or MS Query if it's anything else
Skip all of the menus and paste in your SQL once you get to MS Query
Close MS Query, and your live query (and its results) will be dynamically linked to an Excel table (aka ListObject)
The great thing about this is when you want to refresh the query, right-click and refresh. Done.
Better still, you can set up the ODBC connection for your boss and he can do it himself.
Oh, and if you want this split into two datasets, change your SQL to pull the first half and the second half and have them each in a different worksheet. How you do this depends on your DBMS, which I'd encourage you to tag in your question.
I have a excel file which keeps updating in 15 minutes.
I want to store all the excel data to oracle database automatically. I mean when ever new rows insert into excel file it must insert into oracle database immediately. If any duplicate rows added to excel file it should not be inserted into database.
I need to read a Microsoft Excel 2003 file (.xls) from a query in SQL Server 2005, and then insert some of that data into some tables. Reading the file and then using its data is not a problem in itself, but I found that, for a column, sometimes I get a NULL value instead of the value that's shown in the Excel file. To be more specific: This column is always just one character long, and it can contain any one digit from 0-9, or the letter 'K'. It's when the column contains 'K' that the query gives me a NULL value. My assumption is that, since the first few rows contain numbers as the values of this column, the query assumes they will always be numbers, and when it finds a letter it just turns it into NULL.
I tried changing the format of the cells in the Excel file to text, and using CAST and CONVERT (not at the same time) on the value to try to make it a varchar, but it does nothing.
That looks like an older OLE DB driver for Excel. Not that it doesn't work--you can still "query" the spreadsheet with it. Maybe try something newer:
SELECT * FROM
OPENROWSET('Microsoft.ACE.OLEDB.12.0',
'Excel 12.0 Xml;HDR=YES;Database=C:\File.xls',
'SELECT * FROM [Sheet1$]')
You'll need an updated ODBC driver on the SQL Server (make sure to get the appropriate 32 vs 64 bit version).
I need to create an SSIS package for importing data from multiple Excel files into an SQL database. I plan on using nested Foreach Loop containers to achieve this. One Foreach File Enumerator and nested within that, a Foreach ADO.net Schema Rowset Enumerator
Problem to consider: Sheet names are different between excel files but structure remains the same.
I have created an Excel Connection Manager, but the Schema Rowset Enumerator is not accepting the connection manager in the Enumerator configuration.
After researching, I found that you can use the Jet Ole db provider to connect to an excel file. However, I can only specify Microsoft Access Database Files as the data source. Attempting to insert an Excel File as the data source fails
After more research I found that you can use the Odbc Data Provider with a connection string instead of a DSN. After inserting a connection string specifying the Excel file this also failed
I have been told not to use a Script Task to accomplish this and even after trying a last ditch effort to extract data from sheets be accessing the sheets by index I found that the index for the sheets in the different excel files are different
Any help would be greatly appreciated
Here is one possible way of doing this based on the assumption that there will not be any blank sheets in the Excel files and also all the sheets follow the exact same structure. Also, under the assumption that the file extension is only .xlsx
Following example was created using SSIS 2008 R2 and Excel 2007. The working folder for this example is F:\Temp\
In the folder path F:\Temp\, create an Excel 2007 spreadsheet file named States_1.xlsx with two worksheets.
Sheet 1 of States_1.xlsx contained the following data
Sheet 2 of States_1.xlsx contained the following data
In the folder path F:\Temp\, create another Excel 2007 spreadsheet file named States_2.xlsx with two worksheets.
Sheet 1 of States_2.xlsx contained the following data
Sheet 2 of States_2.xlsx contained the following data
Create a table in SQL Server named dbo.Destination using the below create script. Excel sheet data will be inserted into this table.
CREATE TABLE [dbo].[Destination](
[Id] [int] IDENTITY(1,1) NOT NULL,
[State] [nvarchar](255) NULL,
[Country] [nvarchar](255) NULL,
[FilePath] [nvarchar](255) NULL,
[SheetName] [nvarchar](255) NULL,
CONSTRAINT [PK_Destination] PRIMARY KEY CLUSTERED ([Id] ASC)) ON [PRIMARY]
GO
The table is currently empty.
Create a new SSIS package and on the package, create the following 4 variables. FolderPath will contain the folder where the Excel files are stored. FilePattern will contain the extension of the files that will be looped through and this example works only for .xlsx. FilePath will be assigned with a value by the Foreach Loop container but we need a valid path to begin with for design time and it is currently populated with the path F:\Temp\States_1.xlsx of the first Excel file. SheetName will contain the actual sheet name but we need to populate with initial value Sheet1$ to avoid design time error.
In the package's connection manager, create an ADO.NET connection with the following configuration and name it as ExcelSchema.
Select the provider Microsoft Office 12.0 Access Database Engine OLE DB Provider under .Net Providers for OleDb. Provide the file path F:\Temp\States_1.xlsx
Click on the All section on the left side and set the property Extended Properties to Excel 12.0 to denote the version of Excel. Here in this case 12.0 denotes Excel 2007. Click on the Test Connection to make sure that the connection succeeds.
Create an Excel connection manager named Excel as shown below.
Create an OLE DB Connection SQL Server named SQLServer. So, we should have three connections on the package as shown below.
We need to do the following connection string changes so that the Excel file is dynamically changed as the files are looped through.
On the connection ExcelSchema, configure the expression ServerName to use the variable FilePath. Click on the ellipsis button to configure the expression.
Similarly on the connection Excel, configure the expression ServerName to use the variable FilePath. Click on the ellipsis button to configure the expression.
On the Control Flow, place two Foreach Loop containers one within the other. The first Foreach Loop container named Loop files will loop through the files. The second Foreach Loop container will through the sheets within the container. Within the inner For each loop container, place a Data Flow Task that will read the Excel files and load data into SQL
Configure the first Foreach loop container named Loop files as shown below:
Configure the first Foreach loop container named Loop sheets as shown below:
Inside the data flow task, place an Excel Source, Derived Column and OLE DB Destination as shown below:
Configure the Excel Source to read the appropriate Excel file and the sheet that is currently being looped through.
Configure the derived column to create new columns for file name and sheet name. This is just to demonstrate this example but has no significance.
Configure the OLE DB destination to insert the data into the SQL table.
Below screenshot shows successful execution of the package.
Below screenshot shows that data from the 4 workbooks in 2 Excel spreadsheets that were creating in the beginning of this answer is correctly loaded into the SQL table dbo.Destination.
I ran into an article that illustrates a method where the data from the same excel sheet can be imported in the selected table until there is no modifications in excel with data types.
If the data is inserted or overwritten with new ones, importing process will be successfully accomplished, and the data will be added to the table in SQL database.
The article may be found here: http://www.sqlshack.com/using-ssis-packages-import-ms-excel-data-database/
Hope it helps.
I had a similar issue and found that it was much simpler to to get rid of the Excel files as soon as possible. As part of the first steps in my package I used Powershell to extract the data out of the Excel files into CSV files. My own Excel files were simple but here
Extract and convert all Excel worksheets into CSV files using PowerShell
is an excellent article by Tim Smith on extracting data from multiple Excel files and/or multiple sheets.
Once the Excel files have been converted to CSV the data import is much less complicated.
