ODBC 3.x Database Writer Parameters

When you enter the Database in the Destination Dataset field, the Database field will be automatically populated in the Parameters box.

Enter the username and password to access the service.

When enabled, the database connection persists for the duration of an FME session.

For example, it may be desirable to maintain a connection when running a batch of 100 workspaces on the same database connection, which saves the processing time required to make and break a database connection.

FME considers the database connection to be the same when the database name, the username, and password are the same.

The time (seconds) after which to terminate a query to the database if it has not yet returned a connection/result.

If it is set to 0, there is no timeout. The default is 30.

Some features may contain out-of-range or invalid attribute values. These features will be rejected and cannot be written to the database. If Yes, the translation aborts immediately after encountering bad data. If No, the translation continues, but rejected features are not written to the database.

The number of features that FME places in each transaction before a transaction is committed to the database.

The default value is 1000.

This parameter allows for the execution of SQL statements before opening a table for writing. For example, it may be necessary to drop a constraint before attempting to write to it. The statements will be executed only when the first feature arrives at the writer.

Available menu options depend on the format.

Multiple SQL commands can be delimited by a character specified using the FME_SQL_DELIMITER directive, embedded at the beginning of the SQL block. The single character following this directive will be used to split the SQL block into SQL statements, which will then be sent to the database for execution. Note: Include a space before the character.

For example:

FME_SQL_DELIMITER ;
DELETE FROM instructors ;
DELETE FROM people
WHERE LastName='Doe' AND FirstName='John'

Multiple delimiters are not allowed and the delimiter character will be stripped before being sent to the database.

Any errors occurring during the execution of these SQL statements will normally terminate the reader or writer (depending on where the SQL statement is executed) with an error. If the specified statement is preceded by a hyphen (“-”), such errors are ignored.

This parameter allows for the execution of SQL statements after a set of tables has been written. For example, it may be necessary to clean up a temporary view after creating it.
