[jira] Created: (OPENJPA-1667) Incorrect column type for LOB streaming in MySQL

Incorrect column type for LOB streaming in MySQL
------------------------------------------------

                 Key: OPENJPA-1667
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1667
             Project: OpenJPA
          Issue Type: Bug
          Components: sql
    Affects Versions: 2.0.0, 1.3.0
         Environment: MySQL 5.1.30
            Reporter: Milosz Tylenda
            Assignee: Milosz Tylenda
            Priority: Minor


After the changes made in OPENJPA-740, a LOB streaming field is mapped to TINYBLOB instead of BLOB in MySQL. This is because column size is -1 and in MySQLDictionary.getColumnType we assume that only size = 0 means "size unknown". Adding a check for -1 will probably resolve the issue.
