Amazon Aurora Spatial (MySQL-Compatible) Writer Parameters
About Database Connections |
---|
Database formats include a Database Connection parameter that defines and stores authentication information. For general information about sharing database connections, please see Note that Database Connection parameters differ slightly, depending on context and/or database format. |
Connection From the Connection parameter in a database format, you can do one of the following: Select an existing, previously defined connection. See the section Reusing a Database Connection in Using Database Connections Select Add Database Connection to define a new connection. See database-specific parameters below, as well as the section Adding a Database Connection in a Workspace in Using Database Connections The new connection can be made visible only to the current user, or can be shared among multiple users. |
Connection Parameters
This specifies the machine running the Amazon Aurora database as either an IP address or host name. The database must have proper permissions and be set up to accept TCP/IP connections if connecting from a remote machine.
When connecting remotely, this specifies the TCP/IP port on which to connect to the DBMS service. The default port is 3306.
This field is automatically populated with the information specified in the Input Dataset field, which specifies the name of the database. The database must exist in the DBMS.
You can view DB clusters and instances in the Amazon RDS console by using the Clusters view, or the AWS command-line interface.
Username and Password
Enter the username and password to access the service.
Advanced
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 (which 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.
If the parameter is set to 0, then the entire write operation occurs in a single transaction.
Default: 1000
This parameter allows for the execution of SQL statements before writing to a table. For example, it may be necessary to clean up a table 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.
