DB Data Provider Index Load properties list identifies the connection parameters and other items you must define for the component.
Property |
Description |
---|---|
Interface |
Identify the method or driver to use to connect to the datasource. |
Host Name |
Identify the datasource. The options that appear in the Host Name list depend on the interface you select. |
Query |
Create a query that retrieves information
from the datasource. Use the predefined variable LoadIndex to qualify
the selection criteria in the WHERE clause. Enclose LoadIndex with
square brackets, because it is evaluated before the query is sent
to the database, for example:
select * FROM SALES WHERE SA_DELIVERYDATE >'[LoadIndex]' ORDER BY SA_DELIVERYDATE Note:
Quote characters differ between database systems. In Microsoft Access databases, use # for datetime values. Use the Query window to create a simple query, or click the Query Designer icon to open the Query Designer. |
Ascending Index |
Select the attribute that contains the ascending index for delta load. |
Property |
Description |
---|---|
User and Password |
Identify an authorized database user and protect the database against unauthorized access. |
Load Index Value |
The maximum value of the ascending index attribute
is automatically used and stored when executing a Sybase IQ InfoPrimer job
or schedule. The Load Index Value simulates the project using the
specific value provided by the user. For example:
2005-01-19100 |
Read Block Size |
Determine the number of records retrieved by the component in a single step. |
Pre Processing SQL |
Create a script that runs during component initialization. Scripts can include one or more SQL statements. If you use multiple statements, separate them with a semicolon (;). |
Post Processing SQL |
Create a script that runs after all components execute. Scripts can include one or more SQL statements. If you use multiple statements, separate them with a semicolon (;). |
Database |
Identify the database to use as datasource. If you select this option, you must also select an appropriate interface, and in some cases, specify an appropriate user ID and password. |
Schema |
Identify the schema or owner you want to use as datasource. The objects that appear are restricted accordingly and new tables are created in the schema you specify. |
Standardize Data Format |
Convert incoming DATE and NUMBER information into a standard format that Sybase IQ InfoPrimer can move between systems that support different formats. Dates are converted into this format: YYYY-MM-DD
hh:mm:ss.s. For example:
2005-12-01 16:40:59.123Numbers are converted using a period (“.”) as the decimal separator. |
Database Options |
Set options that override performance defaults and control the behavior of some transactions. |
Transactional |
All work performed by the component, including preprocessing SQL statements and postprocessing SQL statements, is done in a single database transaction that is committed when the project finishes normally. Select this option to roll back the transaction, if this component encounters an error. |
