SQLite Non-Spatial Writer Parameters

Enter the name of the SQLite3 database file.

• If this option is unchecked (default) and a database already exists, then tables and features are written to the existing database.
• If this option is checked, any existing database is deleted before writing begins.

If no database exists when writing begins, a new database is created.

Note: After a database is deleted, it cannot be recovered – all data is lost.

If a template file is specified, the destination file is replaced with a copy of the template before writing begins.

Specifies which SQL operations will be performed by default by this writer. This default writer-level value can be overwritten at the feature type or table level.

• INSERT: Allows for only INSERT operations.
• UPDATE and DELETE: These writer modes can be overwritten at the feature type level.

The number at which the writer will start writing features into the database. The writer skips the number of features in this parameter, and then it begins writing the features that follow.

Usually, the value specified is 0 (this is the default) – a non-zero value is usually only specified when a data load operation is being resumed after failing partway through.

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

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.

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.
