CAST() now produces warnings when casting a wrong INTEGER or CHAR values. This also applies to implicite string to number casts. (Bug #5912) ALTER TABLE now fails in STRICT mode if it generates warnings. Inserting a zero date in a DATE, DATETIME or TIMESTAMP column during TRADITIONAL mode now produces an error. (Bug #5933) mysql-test/r/bigint.result: New warning added mysql-test/r/cast.result: Added testing of wrong CAST's of strings to numbers and numbers to strings mysql-test/r/create.result: Added test for wrong default values (#5902) mysql-test/r/func_if.result: Changed tests to produce less warnings mysql-test/r/func_misc.result: New warning mysql-test/r/func_str.result: Added missing drop table Changed test to produce less warnings New warnings mysql-test/r/ndb_index_unique.result: Removed wrong default usage mysql-test/r/ps_1general.result: Changed tests to produce less warnings mysql-test/r/row.result: New warnings mysql-test/r/rpl_session_var.result: Changed tests to produce less warnings mysql-test/r/strict.result: New tests for CAST() and zero date handling mysql-test/r/subselect.result: Changed tests to produce less warnings mysql-test/r/type_ranges.result: Changed tests to produce less warnings mysql-test/t/cast.test: Added testing of wrong CAST's of strings to numbers and numbers to strings mysql-test/t/create.test: Added test for wrong default values (#5902) mysql-test/t/func_if.test: Changed tests to produce less warnings mysql-test/t/func_str.test: Added missing drop table Changed test to produce less warnings New warnings mysql-test/t/ndb_index_unique.test: Removed wrong default usage mysql-test/t/ps_1general.test: Changed tests to produce less warnings mysql-test/t/rpl_session_var.test: Changed tests to produce less warnings mysql-test/t/strict.test: New tests for CAST() and zero date handling mysql-test/t/subselect.test: Changed tests to produce less warnings mysql-test/t/type_ranges.test: Changed tests to produce less warnings sql/Makefile.am: Added new include file sql/field.cc: Added warnings for zero dates for DATE, DATETIME and TIMESTAMP Moved Field_blob::max_length() to a more appropriate position Changed type for 'level' in set_warning() to avoid casts sql/field.h: Changed type for 'level' in set_warning() to avoid casts sql/field_conv.cc: Copy date and datetime fields through string in 'traditional' mode to detect zero dates sql/item.cc: Removed compiler warnings Give warnings for wrong CAST of strings -> number sql/item.h: Moved Item_string::val_real() and ::val_int() to item.cc sql/item_row.cc: Better detection of null values (which doesn't produce warnings) sql/item_sum.cc: Better detection of null values (which doesn't produce warnings) sql/item_timefunc.cc: Give warnings for wrong CAST of number -> string sql/my_decimal.cc: Fixed typo in comment sql/mysql_priv.h: Removed prototype for static function Moved defines for error handling to sql_error.h (to be able to use these in field.h) sql/mysqld.cc: Simplify code sql/sql_class.h: Moved to sql_error.h sql/sql_load.cc: Removed wrong cast sql/sql_parse.cc: Fixed wrong printf() sql/sql_table.cc: Made mysql_prepare_table() static Changed references to pointers to make code more readable ALTER TABLE now aborts if one gets warnings in STRICT mode sql/time.cc: Fixed possible wrong call sql/unireg.cc: Removed one call to current_thd Give errors if one uses a wrong DEFAULT value
