Usage
This activity is used to access a table(s) or view(s) within a valid OLE DB Scope. The data access is defined by a dtabase SQL Statement.
Tablename
If you are accessing a single table with the statement (example: SELECT * FROM TABELE1), then the table name is optional. In the case of a more complex statement where you include more than one table (example: SELECT * FROM TABELE1, TABELE2 where TABELE1.PK = TABELE2.pk ....) then you have to define a unique tablename defining the access indicator for the OLE system.
Example
The CreateOLEQueryScope activity, as used in the larger example "Read MetaClass names from UBIK database":
