Variable behavior for .onConflict[X] method of .insert?
Let's say that I create an array of insert statements along the lines of db.insert(targetTable).values(targetValues) and, on a conflict, I want different behavior based on why there was a conflict.
For instance, if the conflict arises due to the
However, if a different field of the insert has a unique violation, I’d want to do nothing like:
And a third field has a foreign key constraint that would be violated by the insert. I would imagine that would look like:
What I’d REALLY like to be able to do is something of my choosing on a conflict like logging the skipped entry to a file. Something like:
Is anything like this possible? Can the .onConflict[X] methods be chained maybe? I’ve found that the Drizzle documentation doesn’t have a very thorough description of the API or the methods’ arguments, etc. so I have a hard time knowing what is and isn’t possible with the package.

iddb.insert(targetTable).values(targetValues).onConflictDoUpdate({ target: targetTable.id, set: targetValues })However, if a different field of the insert has a unique violation, I’d want to do nothing like:
db.insert(targetTable).values(targetValues).onConflictDoNothing({ target: targetTable.anotherUniqueField })And a third field has a foreign key constraint that would be violated by the insert. I would imagine that would look like:
db.insert(targetTable).values(targetValues).onConflictDoNothing({ target: targetTable.fieldWForeignConstraint })What I’d REALLY like to be able to do is something of my choosing on a conflict like logging the skipped entry to a file. Something like:
db.insert(targetTable).values(targetValues).onConflict((conflictObject) => {
if(conflictObject.field === “id”){
conflictObject.update({ target: targetTable.id, set: targetValues })
}
if(conflictObject.field === “anotherUniqueField” {
// write to file here
console.log("this entry was skipped do to a conflict on the field: "anotherUniqueField", targetValues);
// do nothing
return;
}
if(conflictObject.field === “fieldWForeignConstraint” {
// write to file here
console.log("this entry was skipped do to a conflict on the field: “fieldWForeignCosntraint”", targetValues);

return;
