…e (Part of #4269) The literal is kept at the PREPARE (which leaves SQLCODE 0, touches no row) and run at each EXECUTE through EXECUTE IMMEDIATE's path. The oracle precompiler takes the same forms; DYNDEMO proves them on Db2. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

What
EXEC SQL PREPARE name FROM '<INSERT ... VALUES literal>'andEXEC SQL EXECUTE name(noUSING) in the det translator (det/sql.py) and the oracle precompiler (tests/tools/equivalence_sql.py). The literal is kept at the PREPARE (which runs a no-op: SQLCODE 0, no row) and run at each EXECUTE through theEXECUTE IMMEDIATEpath (DetSql.savepoint).Checklist: partial [c:fe6377e7] -- DESCRIBE, EXEC SQL CALL, CONNECT, prepared non-INSERT / EXECUTE ... USING / host-variable text left
Class table (dynamic SQL with source-literal text)
No burned estate issues any of these forms (Q4, 2026-10-05 census); proof is on the synthetic DYNDEMO estate.
