Low Risk
Behavior change is limited to an exception message, and the rest of the PR only adds/retags integration tests for tuple/map handling.
Overview
Fixes
PreparedStatementImpl.buildSQL()to report missing parameters using 1-based JDBC parameter positions instead of 0-based indexes.Adds integration coverage for tuple handling: a new prepared-statement test that writes/reads a
Tuple(String, Int32, Date)viaConnection#createStruct/setObject, plus a newResultSetMetaDataintegration test asserting tuple columns map toTypes.OTHER/Object(and moves the existing map metadata test into the integration group).Written by Cursor Bugbot for commit ce69cb1.
