Let me be very specific with what i need. Problem Statement 1: I have got few text files having numerous records which are delimited by pipeline. These files are there in a remote windows server which are the source file for our daily load into a sql server table. I want to write a scripts which will get the filename from the source file path and the number of records in it.–
Next task is to get the counts from sql server table which is ther in an another server(remote) and then validate the counts of table and file.
Please help.....

I have data flow task, which import data from sql server to excel. Currently it requires to have excel templated in place, meaning that I have xlsx file with column names without data in my network location. If I run the package the excel will be filled with data.
What is needed: If I run ssis package I need new xlsx file to be created every time if package is executed. So I need to just create xlsx file with define columns every time and the xlsx file name should include date.
I imagine that I have to set up script task before data flow task, which just creates xlsx file. I am not very familiar with C#, I hope that someone could share the code what to use to achieve this.
Or, you could create a folder and place a Template excel file with predefined format and no data.
Every time the process runs, it must:
Copy the file using File System task to the destination location
Use Data flow task to populate the data into the file in the Destination location
Rename the file in the Destination location as required
My goal is to build automatic process, which imports data from multiple xlsx files from certain directory to sql server database in regular phases.
I already created SSIS package, which imports data to sql server database. But everytime if I run this package, all xlsx files data will be inserted, but I would not like to import all data again, I would like to import just those xlsx files again, which have been updated after last import.
Currently my data flow is following:
Excel source > OLE DB Destination which runs inside foreach loop container.
I imagine something like that:
I have to insert last import timestamp with file name into some log table and then have to compare it with the xlsx last modified date. But I do not know how to do it. Hope that someone could provide some step by step instructions.
This link will give you step by step answer.
You need to take care about flat file connection to excel file connection and join based on last modified date column.
I have some csv files. I want to write SQL Server script to read the file at certain period and insert in SQL Server db, if record is not found and ignore it if file has already been read previously by scheduler. Each csv will contain one record only.
Like:
1.csv => John,2000,2012/12/12
2.csv => Tom,3000,2012/12/11
It will be great if someone can provide examples of script.
Thanks!
If I was you I would create an SSIS package that uses the multi file input. This input let's you pull data from every file in a directory.
Here are the basic steps for your SSIS package.
Check if there are any files in the "working" directory. If not end the package.
Move every file from your "working" directory to a "staging" directory.
You will do this so that if additional files appear in your "working" directory while you are in the midst of the package you won't lose them.
Read all of the files in the "staging" directory. Use a data flow with the multi file input.
Once the reading has been completed then move all of the files to a
"backup" directory.
This of course assumes you want to keep them for some reason. You could just as easily delete them from the "staging" directory.
Once you have your package completed then schedule it using SQL Server agent to run the package at whatever interval you are interested in.
I have a folder with a .sql files; 1 file per query. I want to execute all queries/ sql files and save them as csv.
Is there a way to do that automated without using the windows cli (disabled in my environment). I do have the SQL Server Management Studio.
I would approach this task using SSIS, providing you have Business Intelligence Development Studio (BIDS) installed.
First create a 'Foreach Loop Container' pointed to the folder with the SQL files, then use a variable to retreive each file name.
Next, create a flat file connection and set the 'Connection String' property to the variable that contains the file location.
Next, using the 'Execute SQL Task' component set the 'SQLSourceType' to 'File Connection' and the 'FileConnection' to the one created in the previous step.
Finally, depending on how the data is returned you have a couple of options, if the result set is small, only a row or a single column, then you can save the results to a variable and using a 'Dataflow' task create a 'Derived Column' component and export the contents of that variable to a CSV file. Or, if the dataset is larger you could dump the results to a temp table and then using an 'OLE DB Source' and 'OLE DB Destination' you could push the full result set straight into a CSV.
Hopefully this isn't too convoluted of a solution, this approach has the advantage of being able be run from either a remote machine or from the server itself, plus you can automate its execution with a SQL Agent Job.
Create a VB.NET console application.
Generate a list of files that end in .SQL from the folder in question.
Load the contents of each file into individual SQL Commands
Execute the SQL Command for each, storing the results in DataSets.
For each table in each dataset, create a new .csv file
For each .csv file, you will need to iterate over each cell in the datatable, and utilize proper escaping for .csv files.
Use 'for' in combination with either sqlcmd or bcp command for each file in the script folder.
I'm fairly new to SQL Server.
I'm trying to bulk insert into a table, using the command in SQL Server Management Studio (2005):
BULK INSERT Table1 FROM 'c:\text.txt' WITH (FIELDTERMINATOR = '|')
I get the error:
Msg 4860, Level 16, State 1, Line 1
Cannot bulk load. The file "c:\text.txt" does not exist.
I'm positive the file actually exists.
I get the feeling that it is looking for the file on the local hard drive for where ever the server is. Is that the case? If so, how do you generally solve this problem? (to note, I've tried specifying the network address of my PC when entering the location of the text file, but I get a permission error. Also, I know in advance that my company doesn't allow files to placed on a server).
SQL Server does not have an SQL statement that reads data from the client end (as the other posters have pointed out). Other RDBMS products do implement this (eg. the Postgres COPY statement lets you specify a file on the server or a file on the client that is read by the db connectivity library on the client side).
You can achieve moving data from a file on the client to a table on SQL Server using the bcp command line program.
bcp lets you copy data from a local file to a table on the server, or from a table (or select query) on the server into a local file. For example:
bcp servername.dbname.tablename in c:\temp.txt -T -c
will copy a tabbed delimited file (temp.txt) into the specified table (assuming the file contains the right number of columns).
I am not sure if this helps, but it is the only way to move data from a client file to a server table without giving the server some sort of access across the network to the data file on client.
I'd agree that it's a problem with the file being on your C drive, and not the server's drive.
If it's a permissions issue, have you tried creating a file share on your workstation that the server does have permissions to read from? Maybe something like \YourWorkstation\SQLFile, and then granting everyone (or Guest, depending on how your network permissions are set up) read access on it?
If you can't create the share on your laptop, or you can't grant rights to it for some reason, is there a file share somewhere in the office that you do have rights to, and that SQL can also read from? Maybe a NAS or a "Common" network folder?
Have you created a share drive on your machine that the server can see? If so then you just need to refer to the path including your machine name instead of C:
Yes, it will look for the file on the SQL server itself.
If you can map a network drive to the C drive of your SQL server, then you can just copy the file over before running the bulk insert.
If you absolutely can't get any access to the server's file system, then you can look at doing something like this:
write a program that reads your text file and inserts the contents into single record in a temporary table that has a Text field, perhaps using a stored procedure
have the program execute the bcp command to export the data from the temporary table into a text file on the SQL server's local file system, to a folder that the account under which the SQL service is running has write permission
have the program run a bulk insert command specifying the path to the text file on the server
delete the text file and the temporary table
