This section contains information that is specific to the database type Netezza.

Supported Functions

The Netezza database can be used with:

sqlexec (APL)
SQL Loader Agent

For data loading, it is recommended that you use the SQL Loader Agent. You can also use APL function sqlExec for both data loading and unloading. For information on how to use sqlExec with Netezza see the section below, APL Examples. For further details, see also the IBM Netezza Data Loading Guide.

Preparations

This section describes preparations that you must perform before attempting to connect to a Netezza database.

A driver, provided by your IBM contact, is required to access the Netezza database. This driver must be stored on each host (Platform or EC) that will connect to a Netezza database.

For to access the Netezza database, follow the steps below:

Copy the Netezza files to the directory MZ_HOME/3pp in the Platform or EC.
Restart the Platform and EC for the change to take effect.

APL Examples

This section gives examples of how to use the APL function sqlExec with a Netezza Database profile.

Example - Load data from an external table on the Netezza database host

initialize {
 int rowcount = sqlExec("NETEZZA.NetezzaProfile", 
 "INSERT INTO mytable 
 SELECT * FROM EXTERNAL '/tmp/test.csv' USING (delim ',')");
}

Example - Load data from an external table on the EC host

initialize {
 int rowcount = sqlExec("NETEZZA.NetezzaProfile", 
 "INSERT INTO mytable SELECT * FROM EXTERNAL '/tmp/test.csv' 
 USING (delim ',' REMOTESOURCE 'JDBC')");
}

Example - Unload data to an external table on the EC host

initialize {
 int rowcount = sqlExec("NETEZZA.NetezzaProfile", 
 "CREATE EXTERNAL TABLE '/tmp/test.csv' 
 USING (DELIM ',' REMOTESOURCE 'JDBC') 
 AS SELECT * FROM mytable");
}
