Hello there,
|
||||
|
||||
To make use of the Data Initialization feature in POG Setup, put your insert statements in the data_initialization.sql file. (One per line).
|
||||
Then, on step 1 of Setup, choose "Drop, recreate tables and reset data":
|
||||
|
||||
This will
|
||||
|
||||
1. Drop any tables that have the same name as the object(s) you have in the objects folder.
|
||||
2. Recreate the tables and indexes(if needed)
|
||||
3. Execute the insert statements in data_initialization.sql one by one.
|
||||
|
||||
Regards,
|
||||
The POG Team
