Netezza Spatial Writer Parameters

Specify the name of the Netezza ODBC Data Source Name (DSN). The DSN must specify a database that exists in Netezza.

Enter the username and password to access the service.

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.

Netezza cannot recover from a database error; features that are already written in the current translation will be dropped when a database error occurs. A database error can occur because of an invalid geometry or a database constraint violation. All database errors must result in translation failure. Therefore, this parameter does not affect behavior when a database error occurs.

However, some forms of bad data can be pre-validated and thus not incur database errors. For example, FME can detect out-of-range numeric values before writing them to the database. FME can also detect some types of invalid geometries prior to writing. If No, these bad features are rejected. If Yes, these bad features cause the translation to fail.

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.
