Alexander Barkov	78a891c87b	A partial patch for MDEV-12518 Unify sql_yacc.yy and sql_yacc_ora.yy Making sql_yacc.yy close to sql_yacc_ora.yy: 1. Adding struct sp_cursor_name_and_offset into %union 2. Adding field_type_numeric, field_type_string, field_type_lob, field_type_temporal, field_type_misc 3. Adding keyword_sp_data_type and keyword_sp_not_data_type 4. Removing "opt_savepoint". Moving this grammar to "rollback" instead. This fixes one shift/reduce conflict. 5. Minor indentation cleanup.	9 years ago

Monty	5a759d31f7	Changing field::field_name and Item::name to LEX_CSTRING Benefits of this patch: - Removed a lot of calls to strlen(), especially for field_string - Strings generated by parser are now const strings, less chance of accidently changing a string - Removed a lot of calls with LEX_STRING as parameter (changed to pointer) - More uniform code - Item::name_length was not kept up to date. Now fixed - Several bugs found and fixed (Access to null pointers, access of freed memory, wrong arguments to printf like functions) - Removed a lot of casts from (const char) to (char) Changes: - This caused some ABI changes - lex_string_set now uses LEX_CSTRING - Some fucntions are now taking const char* instead of char* - Create_field::change and after changed to LEX_CSTRING - handler::connect_string, comment and engine_name() changed to LEX_CSTRING - Checked printf() related calls to find bugs. Found and fixed several errors in old code. - A lot of changes from LEX_STRING to LEX_CSTRING, especially related to parsing and events. - Some changes from LEX_STRING and LEX_STRING & to LEX_CSTRING* - Some changes for char* to const char* - Added printf argument checking for my_snprintf() - Introduced null_clex_str, star_clex_string, temp_lex_str to simplify code - Added item_empty_name and item_used_name to be able to distingush between items that was given an empty name and items that was not given a name This is used in sql_yacc.yy to know when to give an item a name. - select table_name."' is not anymore same as table_name. - removed not used function Item::rename() - Added comparision of item->name_length before some calls to my_strcasecmp() to speed up comparison - Moved Item_sp_variable::make_field() from item.h to item.cc - Some minimal code changes to avoid copying to const char * - Fixed wrong error message in wsrep_mysql_parse() - Fixed wrong code in find_field_in_natural_join() where real_item() was set when it shouldn't - ER_ERROR_ON_RENAME was used with extra arguments. - Removed some (wrong) ER_OUTOFMEMORY, as alloc_root will already give the error. TODO: - Check possible unsafe casts in plugin/auth_examples/qa_auth_interface.c - Change code to not modify LEX_CSTRING for database name (as part of lower_case_table_names)	9 years ago
Alexander Barkov	33b6a347e4	MDEV-12533 sql_mode=ORACLE: Add support for database qualified sequence names in NEXTVAL and CURRVAL	9 years ago
Monty	847eb24b17	Fixed some wrong/inconsistent error message - Added trigger name to "Trigger already exists" error message - Added also missing query name to ER_DUP_QUERY_NAME - Fixed wrong use of MASTER_DELAY_VALUE_OUT_OF_RANGE	9 years ago
Monty	17a87d6063	MDEV-10139 Support for SEQUENCE objects Working features: CREATE OR REPLACE [TEMPORARY] SEQUENCE [IF NOT EXISTS] name [ INCREMENT [ BY \| = ] increment ] [ MINVALUE [=] minvalue \| NO MINVALUE ] [ MAXVALUE [=] maxvalue \| NO MAXVALUE ] [ START [ WITH \| = ] start ] [ CACHE [=] cache ] [ [ NO ] CYCLE ] ENGINE=xxx COMMENT=".." SELECT NEXT VALUE FOR sequence_name; SELECT NEXTVAL(sequence_name); SELECT PREVIOUS VALUE FOR sequence_name; SELECT LASTVAL(sequence_name); SHOW CREATE SEQUENCE sequence_name; SHOW CREATE TABLE sequence_name; CREATE TABLE sequence-structure ... SEQUENCE=1 ALTER TABLE sequence RENAME TO sequence2; RENAME TABLE sequence TO sequence2; DROP [TEMPORARY] SEQUENCE [IF EXISTS] sequence_names Missing features - SETVAL(value,sequence_name), to be used with replication. - Check replication, including checking that sequence tables are marked not transactional. - Check that a commit happens for NEXT VALUE that changes table data (may already work) - ALTER SEQUENCE. ANSI SQL version of setval. - Share identical sequence entries to not add things twice to table list. - testing insert/delete/update/truncate/load data - Run and fix Alibaba sequence tests (part of mysql-test/suite/sql_sequence) - Write documentation for NEXT VALUE / PREVIOUS_VALUE - NEXTVAL in DEFAULT - Ensure that NEXTVAL in DEFAULT uses database from base table - Two NEXTVAL for same row should give same answer. - Oracle syntax sequence_table.nextval, without any FOR or FROM. - Sequence tables are treated as 'not read constant tables' by SELECT; Would be better if we would have a separate list for sequence tables so that select doesn't know about them, except if refereed to with FROM. Other things done: - Improved output for safemalloc backtrack - frm_type_enum changed to Table_type - Removed lex->is_view and replaced with lex->table_type. This allows use to more easy check if item is view, sequence or table. - Added table flag HA_CAN_TABLES_WITHOUT_ROLLBACK, needed for handlers that want's to support sequences - Added handler calls: - engine_name(), to simplify getting engine name for partition and sequences - update_first_row(), to be able to do efficient sequence implementations. - Made binlog_log_row() global to be able to call it from ha_sequence.cc - Added handler variable: row_already_logged, to be able to flag that the changed row is already logging to replication log. - Added CF_DB_CHANGE and CF_SCHEMA_CHANGE flags to simplify deny_updates_if_read_only_option() - Added sp_add_cfetch() to avoid new conflicts in sql_yacc.yy - Moved code for add_table_options() out from sql_show.cc::show_create_table() - Added String::append_longlong() and used it in sql_show.cc to simplify code. - Added extra option to dd_frm_type() and ha_table_exists to indicate if the table is a sequence. Needed by DROP SQUENCE to not drop a table.	9 years ago

Alexander Barkov	48a7ea6da3	Uninitialized Column_definition::pack_flag for ROW-type SP variables and their fields Fixed that the Column_definition::pack_flag member corresponding to ROW-type SP variables and their fields was not properly initialized. This lead to sporadic test failures. Valgrind complained about jumps depending on uninitialized value in VALGRIND builds. This patch makes sure that sp_head::fill_spvar_definition() is always called for ROW variables and their fields. Additionally, fixed that a function with a scalar parameter erroneously acceptes ROWs with one fields. Now an error is returned.	9 years ago

Alexander Barkov	9dfe7bf86d	MDEV-10598 Variable declarations can go after cursor declarations Based on a contributed patch from Jerome Brauge.	9 years ago
Alexander Barkov	84c55a5668	MDEV-10581 sql_mode=ORACLE: Explicit cursor FOR LOOP MDEV-12098 sql_mode=ORACLE: Implicit cursor FOR loop	9 years ago
Alexander Barkov	f429b5a834	MDEV-12011 sql_mode=ORACLE: cursor%ROWTYPE in variable declarations Implementing cursor%ROWTYPE variables, according to the task description. This patch includes a refactoring in how sp_instr_cpush and sp_instr_copen work. This is needed to implement MDEV-10598 later easier, to allow variable declarations go after cursor declarations (which is currently not allowed). Before this patch, sp_instr_cpush worked as a Query_arena associated with the cursor. sp_instr_copen::execute() switched to the sp_instr_cpush's Query_arena when executing the cursor SELECT statement. Now the Query_arena associated with the cursor is stored inside an instance of a new class sp_lex_cursor (a LEX descendand) that contains the cursor SELECT statement. This simplifies the implementation, because: - It's easier to follow the code when everything related to execution of the cursor SELECT statement is stored inside the same sp_lex_cursor object (rather than distributed between LEX and sp_instr_cpush). - It's easier to link an sp_instr_cursor_copy_struct to sp_lex_cursor rather than to sp_instr_cpush. - Also, it allows to perform sp_instr_cursor_copy_struct::exec_core() without having a pointer to sp_instr_cpush, using a pointer to sp_lex_cursor instead. This will be important for MDEV-10598, because sp_instr_cpush will happen after sp_instr_cursor_copy_struct. After MDEV-10598 is done, this declaration: DECLARE CURSOR cur IS SELECT * FROM t1; rec cur%ROWTYPE; BEGIN OPEN cur; FETCH cur INTO rec; CLOSE cur; END; will generate about this code: +-----+--------------------------+ \| Pos \| Instruction \| +-----+--------------------------+ \| 0 \| cursor_copy_struct rec@0 \| Points to sp_cursor_lex through m_lex_keeper \| 1 \| set rec@0 NULL \| \| 2 \| cpush cur@0 \| Points to sp_cursor_lex through m_lex_keeper \| 3 \| copen cur@0 \| Points to sp_cursor_lex through m_cursor \| 4 \| cfetch cur@0 rec@0 \| \| 5 \| cclose cur@0 \| \| 6 \| cpop 1 \| +-----+--------------------------+ Notice, "cursor_copy_struct" and "set" will go before "cpush". Instructions at positions 0, 2, 3 point to the same sp_cursor_lex instance.	9 years ago
