BUG#26495791: CONTRIBUTION: EXPAND TEST SUITE TO INCLUDE CRC32 TESTS
From mysql-server: 09fdfad50764ff6809e7dd5300e9ce1ab727b62a e90ae1707e0ca46abc775d1680d1856c4be38b66 described in http://github.com/mysql/mysql-server/pull/157 Apart from external contribution I have added few more additional testcases for CRC32() function, which are given below. New Testcases added: ->Verify the crc value of various numeric and string data types(int, double, blob, text, json, enum, set) ->Verify the crc value when expressions having comparison_operators and logical_operators ->Verify the crc value for the expression having string_functions, arithmetic_functions, json_functions ->Verify the crc value for the expression having Geometry functions like POINT, LINESTRING, MULTILINESTRING, POLYGON, MULTIPOLYGON ->Verify the crc value generated from stored procedures, functions, triggers, prepare statement, views. Fix: Patch based on contribution by Daniel Black (Github user: grooverdan) Reviewed-by: Anitha Gopi anitha.gopi@oracle.com Reviewed-by: Srikanth B R srikanth.b.r@oracle.com RB: 17294
