Updating a sql table from excel
Under Custom Properties select SQLCOMMAND and the button at the end of the input. You are now prompted with an input box, you need to enter an SQL update command (example below) d.
You then need to configure the parameter mappings top the columns (example below) With that complete you are done!!
And if so, would there ever be updates, wouldn't it all just be inserts. Cells(l Row, 2) SQLSelect = "select ID from Test where Country= ' " & Col A & " ' and Name=' " & Col B & " ' and Month=' " & Split Month& " ' and Year=' " & Split Year & " ' " Cn.
You need to make these design decisions before the code can be finished. Execute SQLSelect You totally ignored every point I made, every question I asked.
At this stage we can determine which rows of the Excel sheet are new, and which exist already. Before sorting the columns, I would advise converting the Excel columns to the same type as database columns, in this case I have selected the four columns: a. The data belonging to the new row will be inserted into the table, and the data belonging to the Existing Row will update said row. Drag the line from the conditional split to the OLE DB Destination, you will be prompted to choose the output, you want to select New Row (as defined in the Conditional Split) 4.
cursor1 is for the key column and cursor2 is for the column selected by the user input cursor1 = Data Value Cursor. sql Command = "ALTER TABLE Products ADD " col Name " varchar(50);" dbsettings = Database Data Source Settings( "System. Sql Client", "Server=localhost; Database=Northwind; UID=myuser; PWD=mypass",sql Command) ds = Database Data Source(dbsettings) new Data Table = Document.
I am going to assume you know the basics of SSIS and so will start from the perpective of a new project in BIDS. Now that is in place, both streams of data need to be sorted by the ID columns (note, make sure you pass through the columns you have just converted and don’t pass through the Excel columns. We will perform the left outer join and the conditional to determine if each row is either a new row or existing row. Double click on the Merge Join, select the UID column from the database, and the UID, First Name, Surname, and Age columns from the Excel Source. Remeber to change the join type to Left outer Join Now we can perform the conditional split: 1.
Now things get exciting, we want to create a data flow that queries both the Excel File and the database table, both will need to be sorted on the same column, and then we perform a left outer join. Configure the Excel Source to open our Excel file (you will need to create an Excel Connection manager) 3. Configure the OLE DB source to reference the person table (you will need to create an OLE DB Connection manager instance) 5. Double click the conditional split and configure as shown below: This will now give us two streams coming out of the conditional split, those belonging to the the New Row and those belonging to the Existing Row. Configure the OLD DB Destination to insert to the person table 3.
But what my question is why can't i get the ID for each iteration in excel from sql table and if the ID holds some value,i will update the record with that ID other wise i can insert the record.
weather am i going or thinking in a not possible way?
