Trigger creation fails with error 4016 when CALLing a procedure with ENUM INOUT parameter inside trigger

Environment

• Version: OceanBase seekdb (r) (Built 1-042b4c3c6ef9b8a461555ee3cf6e2eccd1e03376 Apr 9 2026)
• Platform: arm64
• Runtime Environment: Android Virtual Device (emulator-5554) created by Android Studio
• Startup Command: ./data/local/tmp/seekdb --nodaemon --base-dir /data/local/tmp/seekdb_data --port 5881
• Listening Port: 5881

Description

When running the mysqltest test case pl.pl_enum_set_bugs_mysql on an Android emulator, the creation of a trigger fails with error 4016 Internal error. The trigger contains a CALL statement to a procedure that has an ENUM INOUT parameter. The same test passes on a Linux environment.

Steps to Reproduce

1. On the target machine, navigate to the directory: /obdata/data/AndroidTest/ob_opensource_test/tools/deploy
2. Execute the following commands:

export OCEANBASE_HOME=/obdata/data/AndroidTest/ob_opensource_test/
cd ${OCEANBASE_HOME}/tools/deploy
source activate_obd.sh
export OBD_SEEKDB_STATUS_FALLBACK_TCP=1

obd test mysqltest test_env --mysqltest-bin=${OCEANBASE_HOME}/deps/3rd/u01/obclient/bin/mysqltest --obclient-bin=${OCEANBASE_HOME}/deps/3rd/u01/obclient/bin/obclient --init-only --init-sql-dir=${OCEANBASE_HOME}/tools/deploy --init-sql-files='init.sql,init_user.sql|root@sys|test'
obd test mysqltest test_env --mysqltest-bin=${OCEANBASE_HOME}/deps/3rd/u01/obclient/bin/mysqltest --obclient-bin=${OCEANBASE_HOME}/deps/3rd/u01/obclient/bin/obclient --disable-reboot --test-set=pl.pl_enum_set_bugs_mysql

Actual Result

• On Android Emulator: The test fails with error 4016 Internal error during trigger creation.
• On Linux: The test passes successfully.

Additional Context

The issue appears to be specific to the Android (arm64) platform when handling the creation of a trigger that invokes a stored procedure with an ENUM INOUT parameter.

Start by running the mysqltest case pl.pl_enum_set_bugs_mysql with the supplied obd commands on the Android arm64 environment, then compare trigger creation with Linux. Focus on the trigger that CALLs a procedure with an ENUM INOUT parameter; done means the test passes on Android without error 4016.
