Advanced
Features Per Transaction
The number of features that FME places in each transaction before a transaction is committed to the database.
The default value is 1000.
Query Timeout (Seconds)
This parameter defines the time, in seconds, after which a query will be terminated if it has not yet returned a result.
If set to zero, there is no timeout. The default is 30.
Note: If this value is not set high enough, then the query will return the error Provider Error - Timeout Expired.
SQL to Run Before Write
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.
SQL to Run After Write
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.
