Actian Ingres Non-Spatial Reader Parameters

Database Connections

Connections store authentication information. For general information about sharing database connections, please see Using Database Connections.

Note: Depending on context and/or database format, you might see different combinations of Database Connection parameters.

ClosedConnection

Select an existing connection, or Add Database Connection to define a new connection.

The new connection can be made visible only to the current user, or can be shared among multiple users.

Connection Parameters

ClosedHost

This specifies the machine running Ingres database as either an IP address or host name.

ClosedPort

When connecting remotely, this specifies the TCP/IP port on which to connect to the Ingres database service. The default port is II7, which maps to a port number dynamically chosen by the Ingres service when it was installed.

ClosedDatabase

This specifies the name of the Ingres database.

ClosedUsername and Password

Enter the username and password to access the database, user account, or wherever authentication is required.

ClosedQuery 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.

Constraints

ClosedTable List

After you have specified the database connection, click the Browse button to select tables for import. A connection window appears while the system compiles a table from the database.

Once the table list appears, you can select one or more tables, and then click OK to dismiss the window. The table name(s) will appear in the Table List field in the parameter box.

Schema Attributes

ClosedAdditional Attributes to Expose

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

  • In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
  • In a non-dynamic scenario, you can use this parameter to expose additional attributes on multiple feature types.

Advanced

ClosedSQL to Run Before Read

This parameter allows for the execution of SQL statements before opening a table for reading. For example, it may be necessary to create a temporary view before attempting to read from it.

For detailed information about SQL functions, click the corresponding menu item in the SQL to Run editor helpClosed.

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.

ClosedSQL To Run After Read

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