DB Data Sink Update properties list

The following tables list the required and optional properties of the DB Data Sink Update component. Required properties are displayed in bold text.

Required properties

Property	Description
Interface	Specify the method or driver you want to use to connect to the data source.
Host Name	Specify the data source. Options available on the Host Name list depend on the Interface you select. If you use SQLite as a Host, type the path and file name to the SQLite database file (For example, c:\mySQLite.db). If a database with the name you specify does not exist, SQLite will create one.
Destination Table	Click the Destination Table icon to select the destination table from a set of existing tables. You can also create a new Destination table based on a component’s port structure. See “Adding a Destination table”.
Key	Select the columns of the Destination table that identify the records to update. You must select a Destination table before you can select a key, and you can select multiple key columns.

Optional properties

Property	Description
User and Password	Specify an authorized database user and a password to protect the database against unauthorized access.
Update Options	Click the Update Options icon to select the attributes (key attributes are not listed) you want to include in the update. By default, all attributes are selected. Unselect those attributes you want to exclude from the update. In the SQL UPDATE SET clause column, you can overwrite the value of the incoming attribute with a new one. The new value can be a constant or an expression. In SQL language notation the contents of the columns will be processed as: UPDATE customersSET cu_createdate = '2005-02-26'WHERE …. You can use any expression allowed in the SQL language of the underlying database. Dynamic expression in square brackets will be evaluated during initialization of the component.
Write Block Size	Specify the number of records to be written to the file or pipe in a single write operation.
Pre-processing SQL	Click the Pre-processing SQL icon to open a window where you can create a query that runs during component initialization. Queries can include one or more SQL statements. If you use multiple statements, separate them with a semicolon (;).
Post-processing SQL	Click the Post-processing SQL icon to open a window where you can create a query that runs after all components execute. Queries can include one or more SQL statements. If you use multiple statements, separate them with a semicolon (;).
Opening Attribute Quote	Specify a prefix for attribute names in SQL statements.
Closing Attribute Quote	Specify a postfix for attribute names in SQL statements.
Database	Specify the database you want to use as data source. Additionally, you must select an appropriate interface, and in some cases, specify an appropriate user ID and password.
Schema	Identifies the schema/owner you want to use as data source. The objects displayed will be restricted accordingly and new tables will be created in that schema.
Standardize Data Format	Select the option to convert incoming `DATE` and `NUMBER` information into a standard format that Sybase ETL can move between systems that support different formats. Dates are converted into a format that includes the year, month, day, hour, minute, seconds, and fraction of a second: `YYYY-MM-DD hh:mm:ss.s`. For example, 2005-12-01 16:40:59.123 Numbers are converted with a '`.`' as the decimal separator.
IQ Lock Table in Exclusive Mode	Select the option to lock the target table and prevent it from being updated by concurrent transactions. When an exclusive table lock is applied, no other transaction can execute queries or perform any updates against the locked table. The IQ Lock Table in Exclusive Mode option also queues multiple projects that load the same table in Sybase IQ.
Wait Time for IQ Lock Table	Specify the maximum blocking time that the project should wait, before acquiring an Exclusive lock. Specify the time argument in the format hh:nn:ss.sss. If you do not enter a time argument, the server waits indefinitely until an Exclusive lock is available or an interruption occurs. When you specify “00:00:00.000” as the time argument, an Exclusive lock is acquired as soon as the project starts.
Database Options	Click the Database Options icon to set options that override performance defaults and control the behavior of some transactions. See “Database connection settings”.
