Alexey Botchkov d9ea0d0cd5 Bug#41371 Select returns 1 row with condition "col is not null and col is null" ... For application compatibility reasons MySQL converts "<autoincrement_column> IS NULL" predicates to "<autoincrement_column> = LAST_INSERT_ID()" in the first SELECT following an INSERT regardless of whether they're top level predicates or not. This causes wrong and obscure results when these predicates are combined with others on the same columns. Fixed by only doing the transformation on a single top-level predicate if a special SQL mode is turned on (sql_auto_is_null). Also made sql_auto_is_null off by default. per-file comments: mysql-test/r/func_isnull.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" test result updated mysql-test/t/func_isnull.test Bug#41371 Select returns 1 row with condition "col is not null and col is null" test case added sql/mysqld.cc Bug#41371 Select returns 1 row with condition "col is not null and col is null" sql_auto_is_null now is OFF by default. sql/sql_select.cc Bug#41371 Select returns 1 row with condition "col is not null and col is null" remove_eq_conds() split in two parts - one only checks the upper condition, the req_remove_eq_conds() recursively checks all the condition tree. mysql-test/extra/rpl_tests/rpl_insert_id.test Bug#41371 Select returns 1 row with condition "col is not null and col is null" test fixed (set the sql_auto_is_null variable) mysql-test/r/mysqlbinlog.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/r/mysqlbinlog2.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/r/odbc.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/r/query_cache.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/r/user_var-binlog.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/binlog/r/binlog_row_ctype_ucs.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/binlog/r/binlog_stm_ctype_ucs.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/rpl/r/rpl_insert_id.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/rpl/r/rpl_row_mysqlbinlog.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/suite/rpl/r/rpl_sp.result Bug#41371 Select returns 1 row with condition "col is not null and col is null" result updated mysql-test/t/odbc.test Bug#41371 Select returns 1 row with condition "col is not null and col is null" test fixed (set the sql_auto_is_null variable)		2009-11-03 17:54:41 +04:00
