MSSQLDataWriter loads data into MSSQL database.
|Component||Data output||Input ports||Output ports||Transformation||Transf. required||Java||CTL||Auto-propagated metadata|
|Input||0||||Records to be loaded into the database||Any|
|Output||0||For information about incorrect records||Input 0 (plus three Error Fields for MSSQLDataWriter|
 If no file containing data for loading (Loader input file) is specified, the input port must be connected.
This component has one optional input port and one optional output port.
MSSQLDataWriter does not propagate metadata.
Metadata on the output port 0 contain three additional
fields at their end:
number of incorrect row,
number of incorrect column,

MSSQLDataWriter loads data into a MSSQL database
using the MSSQL database client. SQL Server Client Connectivity Components
must be installed and configured on the same machine where
bcp command line tool must be available.
MSSQLDataWriter reads data through the input port or from a file. If the input port is not connected to any other component, data must be contained in file that should be specified in the component using Loader input file attribute.
If you connect some other component to the optional output port,
it can serve to log the rejected records and information about errors.
Metadata on this error port must have the same metadata fields as the
input records plus three additional fields at its end:
number of incorrect row (integer),
number of incorrect
error message (string).
MSSQLDataWriter is a bulk loader suitable for uploading many records to database.
To insert several records, you can also use DBOutputTable,
which does not require the
Depending on an edge being connected to the input port, you either can or you must specify another attribute (Loader input file). It is the name of an input file with data to be loaded, including its path.
If it is not set, a loader file is created in CloverETL
or OS temporary directory (on Windows) or
is used instead of temporary file (on Unix).
The file is deleted after the load finishes.
If it is set, specified file is created. It is not deleted after data is loaded and it is overwritten on each graph run.
If an input port is not connected, the file must exist, must be specified and must contain data that should be loaded. It is not deleted nor overwritten.
Parameters serve to pass additional parameters to
All of the parameters must have the form of
key only (if its value is
Individual parameters must be separated from each other by a colon, semicolon or pipe.
Note that a colon, semicolon or pipe can also be a part of some parameter value,
but in this case the value must be double quoted.
Among the optional parameters, you can also set
fieldTerminator for User name,
Password or Column delimiter
If some of the three attributes
(User name, Password and
Column delimiter) will be set, corresponding
parameter value will be ignored.
If you also need to specify the server name,
you should do it within parameters.
The pattern is as follows:
For example, you can specify both server name and user name in the
MSSQLDataWriter does not write lists and maps.

Set up the following attributes of MSSQLDataWriter.
|Path to bcp utility||C:/Program Files/Microsoft SQL Server/Client SDK/ODBC/110/Tools/Binn/bcp.exe|
In case the server uses a non-standard port number, append the port number after Server name.
The port number is separated by a comma, not by a semicolon.
To test that the connection to database works, you can read some
database table with
bcp utility directly:
bcp [database_name].[database_schema].[tablename] out outputfile -U user -S serverHostName,port -c
bcp master.dbo.products out products.txt -U doejohn -S mssql.example.com,1435 -c
You can use the utility to check that you can insert records into database table:
bcp [database_name].[database_schema].[tablename] in inputfile -U user -S serverHostName,port -c
bcp master.dbo.products in inputfile.txt -U doejohn -S mssql.example.com,1435 -c
inputfile.txt should be a tab-delimited csv file.
