You can create a dynamic entity that has data stored externally in an IBM DB2 or Oracle relational database management system (RDBMS). (For a list of database versions and platforms supported by Trillium DQ, see Relational Data Sources.)
Before you issue the createentity command, create a loader connection
for the DB2 or Oracle data source. The loader connection specifies where the data source
files are located and allows the createentity command to connect to the
data source and initiate the entity creation process. (For information about creating a
loader connection, see Loader
Connections.)
Syntax
createentity <loader_connection> username <username> password <password> table <table_name>where,
|
<loader_connection> |
Name assigned by the repository administrator to the loader connection. |
|
<username> |
User ID required to validate the connection to the data source. You must always provide the username and password parameters when connecting directly to a relational database management system (RDBMS). |
|
<password> |
Password required to validate the connection to the data source. Use this parameter if a login name and password are required. |
|
<table_name> |
Name of the relational database table to be imported. |
Optional Parameters
|
Parameter |
Description |
|---|---|
|
jobname <job_name> |
Job ID or name of the data load job. |
|
columns {names} |
Indicates the names of the columns from which to import data. |
|
skip <number> |
Number of rows to skip before starting to import data rows. All rows after the skipped rows will be loaded to the repository. For example, if your file has 300 rows and you select to skip the first 99, the system will load 200 rows, starting with the 100th row. |
|
first <number> |
Number of records from the beginning of the file to load (for example, the first 1000 records). |
|
random <percentage> |
The degree to which you want to randomly sample a percentage of records from the file. |
Example
This command connects to a loader connection named db2conn for an
IBM DB2 database. There are three table columns that are used to create the dynamic
entity: div A, player, and score.
createentity db2conn username db2user password db2pwd jobname db2_dyn1 table littleleague columns {{div a} player score}When multiple columns are represented within a space-delimited line of column names, be sure to enclose them in braces ({}). If a column name contains white space, enclose the column name in braces ({}) also.
