PostgreSQL and MySQL support ORDER BY with LIMIT; standard FETCH FIRST syntax is also available in modern versions. Oracle supports FETCH FIRST in current versions; older ROWNUM queries must sort in an inner query before limiting in an outer query. Always specify deterministic ordering and test the exact target version.

Check the intended interpreter and run a syntax check first. Enable xtrace only around the suspect section because it prints expanded values; redirect diagnostics securely and mask credentials. Reproduce with controlled input, inspect each command status, and use ShellCheck to catch common quoting and portability issues.

Bean A needs B while B needs A, so neither constructor can complete first. Treat the exception as an ownership/design signal: extract the shared responsibility, invert a dependency, or communicate through an event. Lazy lookup can defer resolution but does not remove the cycle or its coupling.
