Deleting First Four records in a table
- Thread starter Sreevani
- Start date
Hello Sreevani,
There is really no such thing as "first x records" in a relational database like DB2. It may appear to be if you use a tool to look at the contents, but There is NO guarantee that the representation will be the exact state of the table. If you need to delete records from a table it should be based on precise conditions. If the table has a primary key, you can use this to state the delete action, otherwise use a combination of fields to get the proper conditions.
syntax is very simple:
delete from table
where ................... (the proper conditions)
Remember to give an additional commit or set to auto-commit to make a delete action permanent !!! T. Blom
