![]() This patch implements an Oracle style function to_number() with the following signatures: - to_number(number_or_string_subject) - to_number(string_subject, string_format) The function is implemented in sql/item_numconvfunc.cc. The function returns the DOUBLE data type for all signatures and input data types. The format parser understands the following components: - Digits: 0, 9 - Hex digits: X - Group separators: comma (,) and G - Decimal delimiers: period (.) and D - Approximate number signature: EEEE - Currency/numeric flags: $ and B - Currency signatures: C, L, U - Sign signatures: S, MI, PR - Special format signatures: V, TM, TM9, TME - Format flag: FM Note, the parser was implemented assuming that we'll also have the oppostite function to_char() soon for numeric input. So it parser all known components. However, the function to_number() does not support: - Formats V, TM, TM9, TME. to_number() returns NULL if the format string has these components. These componens are supported only by to_char() in Oracle. Features not inclided into this patch: - The ON CONVERSION ERROR clause - The third parameter (nlsparam) - Internationalized components: G, D, C, L, U. These features will be implemented later, under terms of MDEV-36978. Notable changes in the other files: - item_func.h: adding Item_handled_func::Handler_double - simple_parser.h: adding a number of *CONTAINER* templates They help to save on duplicate code when creating classes suitable for passing into parsing templates such as OPT, OR2C, OR3C, etc - simple_parser.h: Adding parsing templates OR4C and OR5C - simple_parser.h: Moving the template "OPT" towars the beginning of the file Rule parsing templates TOKEN, TokenChoice, AND2, OR2C, OR3C, OR4C, OR5C, LIST now provide a sub-class Opt, to parse its optional rule. - simple_parser.h: Adding "explicit" to all "operator bool" definitions - Renaming Parser_templates::TOKEN to Parser_templates::TokenParser - Adding "explicit" to all "operator bool()" templates/classes, to avoid hidden implicit conversion (to int, void*, etc). - Renaming the LIST template parameter ELEMENT to ELEMENT_PARSER, to make it clearer what it is for. - Renaming the OPT template parameter RULE to RULE_PARSER, to make it clearer what it is for. |

This directory contains test suites for the MariaDB server. To run currently existing test cases, execute ./mysql-test-run in this directory. Some tests are known to fail on some platforms or be otherwise unreliable. In the file collections/smoke_test there is a list of tests that are expected to be stable. In general you do not have to do "make install", and you can have a co-existing MariaDB installation, the tests will not conflict with it. To run the tests in a source directory, you must do "make" first. In Red Hat distributions, you should run the script as user "mysql". The user is created with nologin shell, so the best bet is something like # su - # cd /usr/share/mariadb-test # su -s /bin/bash mysql -c ./mysql-test-run This will use the installed MariaDB executables, but will run a private copy of the server process (using data files within /usr/share/mariadb-test), so you need not start the mysqld service beforehand. You can omit --skip-test-list option if you want to check whether the listed failures occur for you. To clean up afterwards, remove the created "var" subdirectory, e.g. # su -s /bin/bash - mysql -c "rm -rf /usr/share/mariadb-test/var" If tests fail on your system, please read the following manual section for instructions on how to report the problem: https://mariadb.com/kb/en/reporting-bugs If you want to use an already running MySQL server for specific tests, use the --extern option to mysql-test-run. Please note that in this mode, you are expected to provide names of the tests to run. For example, here is the command to run the "alias" and "analyze" tests with an external server: # mariadb-test-run --extern socket=/tmp/mysql.sock alias analyze To match your setup, you might need to provide other relevant options. With no test names on the command line, mysql-test-run will attempt to execute the default set of tests, which will certainly fail, because many tests cannot run with an external server (they need to control the options with which the server is started, restart the server during execution, etc.) You can create your own test cases. To create a test case, create a new file in the main subdirectory using a text editor. The file should have a .test extension. For example: # xemacs t/test_case_name.test In the file, put a set of SQL statements that create some tables, load test data, and run some queries to manipulate it. Your test should begin by dropping the tables you are going to create and end by dropping them again. This ensures that you can run the test over and over again. If you are using mysqltest commands in your test case, you should create the result file as follows: # mariadb-test-run --record test_case_name or # mariadb-test --record < t/test_case_name.test If you only have a simple test case consisting of SQL statements and comments, you can create the result file in one of the following ways: # mariadb-test-run --record test_case_name # mariadb test < t/test_case_name.test > r/test_case_name.result # mariadb-test --record --database test --result-file=r/test_case_name.result < t/test_case_name.test When this is done, take a look at r/test_case_name.result. If the result is incorrect, you have found a bug. In this case, you should edit the test result to the correct results so that we can verify that the bug is corrected in future releases. If you want to submit your test case you can send it to developers@lists.mariadb.org or attach it to a bug report on http://mariadb.org/jira/. If the test case is really big or if it contains 'not public' data, then put your .test file and .result file(s) into a tar.gz archive, add a README that explains the problem, ftp the archive to ftp://ftp.mariadb.org/private and submit a report to https://mariadb.org/jira about it.
