The Database Destination Component is an SSIS Data Flow Component for loading and updating data into a database table. The component can be configured to insert, update, delete or upsert in row-by-row or bulk-load mode for ADO.NET, OLE DB and ODBC connections (see a list of supported databases below). Custom setup and teardown logic is supported via optional pre and post execute SQL commands. Error redirection is available in row-by-row mode and for ODBC bulk-load.
The availability in version 2.0 of the Database Destination Component makes obsolete the following SSIS+ destination components:
- ODBC Destination
- Oracle Destination
- DB2 Destination
- Informix Destination
- Sybase Destination
- Teradata Destination
The component allows usage of three kinds of database connections - ADO.NET, OLE DB and ODBC. Most of them support an optimized bulk-load mode, all support the regular row-by-row data processing.
|SQL Server||regular and bulk||regular and bulk||regular and bulk|
|Oracle||regular and bulk*||regular||regular and bulk||10-30x|
|Teradata||regular||regular||regular and bulk||80x|
|PostgreSQL||regular and bulk||-||regular and bulk||10x|
|DB2||regular and bulk||regular and bulk **||regular||20x|
|MySQL||regular||regular||regular and bulk||30x|
|Informix||regular and bulk||regular||regular||6-8x|
|SAP ASE||regular and bulk||-||regular and bulk|
* The bulk load is supported only with ODP.NET, Unmanaged Driver.
** The bulk load is supported only with Microsoft ODBC Driver for DB2.
In this page the general parameters are configured.
The page allows detailed mapping for each part of the database statement. Depending on the Action a database statement can have maximum three parts - Insert, Update and Match. The page shows mappings tabs according to the selected Action. This allows to specify exactly which columns will be used in each part of the statement. For example when the Action is Upsert, the user can insert all columns and update a few of them. The separated mappings can be used even to update a Primary Key.
In this tab the mappings for the insert part are configured. The tab is visible when the Action is Insert or Upsert.
In this tab the mappings for the update part are configured. The tab is visible when the Action is Update or Upsert.
In this tab the mappings for the match part are configured. The tab is visible when the Action is Update, Delete or Upsert.
Pre&Post Scripts Page
In this page the pre and post execute SQL commands are configured.
Since version 2.2, the component is providing result information in one or two Result Outputs. All of the fields of the destination table are columns of the Result Outputs. The type of
Action determines the availability of result outputs:
"Inserted Records Output" contains the field values of the inserted rows. It includes also the values that are populated automatically by the DBMS (e.g. identity fields).
"Updated Records Output" contains the old and the new field values of the updated records.
Supports both "Inserted Records Output" and "Updated Records Output" outputs (see above).
The "Deleted Records Output" contains the old field values of the deleted rows.
Efficient batch operations
When batch mode is enabled (i.e. when the batch size is specified to a number > 1), an automatically created temporary table is used to speed up the processing. Data is bulk inserted in this table and then the destination table is updated depending on the selected action with a one or more SQL commands. The temporary table is removed in the post-execute phase.
Oracle bulk mode can be used only with the ODP.NET, unmanaged driver. It doesn't allow update of a column used in the match part of the statement because of the Oracle MERGE statement limitations. Oracle OLE DB driver allows enabling of the bulk mode, but the execution is failing.
PostgreSQL ODBC bulk mode is array insert. When complex types are used the loading speed will be slower. Each additional complex column will slow down further.
DB2 ODBC bulk mode is array insert. DB2 OLE DB bulk mode is supported only with the Microsoft ODBC Driver for DB2, the driver doesn't support the field types: LONG VARCHAR FOR BIT DATA, VARGRAPHIC, XML and DECFLOAT.
SAP ASE ADO.NET driver supports bulk-load only in an empty table. An intermediate automatically created temporary table is used. Rows are bulk-loaded in a temporary temp table, then they are transferred to the destination table using SQL command. The temporary table is removed in the post-execute phase.
SAP ASE ODBC bulk mode is array insert when the table has an identity column.
SQL Server and SAP ASE permits inserting value in an identity column. SAP ASE permits updating an identity column. When the destination table has an identity column these modes are supported. Need to be explicitly enabled with the Identity Insert option.
Temporary table schema and database
In Bulk mode, when the Action is Update, Delete or Upsert, a temporary staging table is used, and by default it is created in the destination table schema.
The database and/or database schema of the staging table can be customized via the property TempSchema. It accepts either a schema or a combination of database + schema. E.g. specifying
TempDatabase.dbo for SQL Server will instruct to use a temporary table in a database TempDatabase and schema dbo.
Please note that some databases like DB2 need special configuration to use more than one database in a single SQL statement.
Enabling triggers and other settings with bulk inserts
By default triggers won't fire during a bulk insert, but the firing can be enabled for OLE DB driver and for SQL Server ADO.NET driver. To enable triggers the property FastLoadOptions should contain value FIRE_TRIGGERS.
For OLE DB drivers you can specify in FastLoadOptions property additional settings. Check available options for the SSPROP_FASTLOADOPTIONS property here.
PostgreSQL ADO.NET support requires installation of the Npgsql ADO.NET Data Provider for PostgreSQL.
Because of a bug in SAP ASE ADO.NET driver unsigned smallint, unsigned int, unsigned bigint and smallmoney field types cannot be used.
When used SAP ASE ODBC driver decimal or numeric field types are not working. We have sent the following incident cases: 11553913, 11553762, 11553757.
As of now, the component has been tested with the following databases (depending on database version compatibility, it will work on previous and future versions):
- SQL Server 2017
- Oracle 18c
- Teradata Express 16.20
- PostgreSQL 12.3
- IBM DB2 11.5
- MySql 8.0
- IBM Informix 14.10
- SAP ASE 16.0
In this quick-start we will setup Database Destination to make upsert in a database table. Bulk-copy mode will be used with the default batch size of 1000 rows.
To try upsert you can use the demo package from this archive. You should create a
TEST_TABLE table with the following columns (the archive contains script to do that) :
The NumberOfRows variable controls the number of rows used in the insert and in the upsert phase
Use the parameters below to configure the component.
Select an existing ADO.NET, OLE DB or ODBC connection manager.

Specify the desired action. This parameter has the options listed in the following table.
Action Description Insert Insert new rows in the destination table. Update Update rows matching primary key in the destination table. Delete Delete rows matching primary key in the destination table. Upsert Update rows matching primary key, insert non-matching in the destination table.
Specify the destination database table where the data is loaded, updated or deleted.
Specify the number of rows to be sent as a batch. If the size is set to 1, the component uses regular insert.
Specify the number of seconds allowed for the operation to complete before it is aborted.
Specify if Identity Insert or Identity Update should be allowed. The table must have identity column. Identity Insert is supported on SQL Server and SAP ASE. Identity Update is supported on SAP ASE.
Specify how to handle rows with errors.
