type ResolveTransactionChanges<T, TOperation> = TOperation extends "delete" ? T : Partial<T>;

type ResolveTransactionChanges<T, TOperation> = TOperation extends "delete" ? T : Partial<T>;

Defined in: packages/db/src/types.ts:94

• T extends object = Record<string, unknown>

• TOperation extends OperationType = OperationType

update and insert are both represented as Partial<T>, but changes for insert could me made more precise by inferring the schema input type. In practice, this has almost 0 real world impact so it's not worth the added type complexity.
