begin_download_deletes table event

Processes statements related to a specific table just before fetching a list of rows to be deleted from the specified table in the remote database.

Parameters

In the following table, the description provides the SQL data type. If you are writing your script in Java or .NET, you should use the appropriate corresponding data type. See SQL-Java data types and SQL-.NET data types.

In SQL scripts, you can specify event parameters by name or with a question mark. Using question marks has been deprecated and it is recommended that you use named parameters. You cannot mix names and question marks within a script. If you use question marks, the parameters must be in the order shown below and are optional only if no subsequent parameters are specified (for example, you must use parameter 1 if you want to use parameter 2). If you use named parameters, you can specify any subset of the parameters in any order.

Parameter name for SQL scripts	Description	Order (deprecated for SQL)
s.last_table_download	TIMESTAMP. The last download time for the table.	1
s.remote_id	VARCHAR(128). The MobiLink remote ID. You can only reference the remote ID if you are using named parameters.	Not applicable
s.username	VARCHAR(128). The MobiLink user name.	2
s.table	VARCHAR(128). The table name.	3

Default action

Remarks

This event is executed immediately before fetching a list of rows to be deleted from the named table in the remote database.

Note

For each download table, the begin_download_deletes, download_delete_cursor, and end_download_deletes events are invoked in sequence. Consider implementing all of the download delete logic for a table in a download_delete_cursor event implemented as a single stored procedure that returns a result set containing all of the rows to be deleted from the remote table. The reduced number of script invocations may result in improved download performance.

You can have one begin_download_deletes script for each table in the remote database.
