- Identify the Target Table
- The target table is specified by the variable <%=odiRef.getTable("L","INT_NAME","A")%>.
- This dynamic expression retrieves the name of the target table (likely through Oracle Data Integrator or a similar system).
- Understand the Action
- The task involves running a DELETE SQL command to remove all data from the identified target table.
- The SQL query is structured as:
o delete from <%=odiRef.getTable("L","INT_NAME","A")%>
- This query will delete all rows in the specified table.
- Transaction Context
- The delete operation is executed in a transaction. However, it’s important to note that this transaction is not committed immediately.
- The deletion will only take place if the DELETE_ALL Knowledge Module (KM) option is selected.
- Execution Conditions
- The DELETE_ALL Knowledge Module option needs to be selected to trigger this command. It’s part of a larger ETL (Extract, Transform, Load) process where, if this option is chosen, the data in the target table is deleted.
- Data Deletion
- The DELETE command will remove all data from the target table but will not remove the table itself or its schema.
- Commitment
- Since the operation is not committed by default, the changes (deletion of the rows) will be rolled back unless explicitly committed later in the process.
