If you would like us to spend some time helping you to diagnose the problem, please spend some time describing it and, ideally, providing a minimal sample that reproduces the problem.

[sysmat]

is there any spring property for r3dbc that will log SQL statements, like spring.jpa.show-sql?

[mp911de]

You can enable debug logging if you set the logger org.springframework.r2dbc.core to DEBUG.
