Description

I've seen somewhere in the review exchange a note about REPLACE which should work as possible and fail if not, don't remember anything about IGNORE, and can't find anything in the patch tests. Anyway, it's strange that the result is different for different engines, but if that's expected, please feel free to close, just check that the tests have it.

For InnoDB tables, INSERT IGNORE, REPLACE, LOAD IGNORE, LOAD REPLACE fail when duplicate key situation occurs (and fail with a rather unfortunate ER_FOREIGN_DUPLICATE_KEY_WITH_CHILD_INFO (not included in the test case, it's meant to be run with --force --force to get the complete result, and with --mysqld=--default-storage-engine=....

--source include/have_innodb.inc

# To make all engines equal in this regard

SET sql_mode='STRICT_ALL_TABLES';

# Create an outfile with two identical historical records

create or replace table t (a int) with system versioning;

set system_versioning_insert_history= on;

insert into t (a,row_start,row_end) values (1,'2022-01-01','2023-01-01'),(1,'2022-01-01','2023-01-01');

select a,row_start,row_end into outfile 'f' from t for system_time all;

# Run with default engine of your choice

create or replace table t (a int primary key) with system versioning;

load data infile 'f' replace into table t (a,row_start,row_end);

select a,row_start,row_end from t for system_time all;

create or replace table t (a int primary key) with system versioning;

load data infile 'f' ignore into table t (a,row_start,row_end);

select a,row_start,row_end from t for system_time all;

create or replace table t (a int primary key) with system versioning;

replace into t (a,row_start,row_end) values (1,'2022-01-01','2023-01-01'),(1,'2022-01-01','2023-01-01');

select a,row_start,row_end from t for system_time all;

select a,row_start,row_end from t for system_time all;

# Cleanup

drop table t;

MyISAM behaves correctly. InnoDB is wrong because of the following code in row0ins.cc, function row_ins_duplicate_error_in_clust():

          if (cursor->index->table->versioned()

              && entry->vers_history_row())

                  ulint trx_id_len;

                  byte *trx_id = rec_get_nth_field(

                          rec, offsets, n_unique,

                          &trx_id_len);

                  ut_ad(trx_id_len == DATA_TRX_ID_LEN);

                  if (trx->id == trx_read_trx_id(trx_id)) {

                          err = DB_FOREIGN_DUPLICATE_KEY;

The right solution is to restrict DB_FOREIGN_DUPLICATE_KEY to the proper conditions.
