PreQR: Pre-training Representation for SQL Understanding
Summary: PreQR introduces a pretrained SQL representation with an automaton-encoded query structure and a schema-conditioned graph neural network. Attention-based SQL encoding enables on-the-fly schema linking, replacing one-hot encodings and boosting performance on cardinality estimation and join order.
