ERROR "InnoDB: Records in wrong order" with nopad collation

    XMLWordPrintable

Details

    Description

      I've set it to Minor because the provided data file which LOAD DATA loads into the table contains random garbage, partially binary. The file wasn't generated as "bad" intentionally, but was rather a result of some datatype mix – blob or varbinary columns selected into an outfile or alike, – but it makes the test case unnatural, and I don't have a more convincing one for now. Still, given the corruption nature of the errors, I thought it would better to have it filed. Feel free to do whatever you want with it.

      Download the attached data file and put it into /tmp, or change the location in the test case as needed.

      --source include/have_innodb.inc
       
      CREATE TABLE t (f VARCHAR(64), id INT, KEY(f,id)) ENGINE=InnoDB COLLATE utf8_nopad_bin;
      LOAD DATA LOCAL INFILE '/tmp/load.data' INTO TABLE t;
      CHECK TABLE t EXTENDED;
       
      # Cleanup
      DROP TABLE t;
