Updating two tables in oracle rich men beautiful women dating
Keep in mind, though that the approach above should be your first try. Okay, so that’s it for a scenario that works fine because the “lookup” table (employees) is key-preserved.
By the way, we are using a correlated sub query in this case. So what about a scenario where the lookup table is not key preserved?
The following code example creates and explicitly sets properties to update a two-table view.
You can use this example as a guide for customizing update property settings on a view.
Additional points: There are nine primary labels and each of the nine have multiple details (a company can have all nine primaries and all detail labels).
I would then run queries off of the company table to find companies with the primary and/or detail project label I am currently looking for.
In the past, we'd have accomplished this by a combination of INSERT and UPDATE statements, but starting with Oracle we've now got the Oracle MERGE command which does this in one step.
The MERGE statement is designed to combine multiple operations to reduce the complexity of mixed insert and update operations. a delete statement that affects more than one row).
