DBunit; confusion over case sensitivity on table/c

问题:

I'm getting this error when I start up my application

Caused by: org.dbunit.dataset.NoSuchColumnException: CLIENT.ID -  (Non-uppercase input column: ID) in ColumnNameToIndexes cache map. Note that the map's column names are NOT case sensitive

I'm not too sure why I'm getting this, since my table/column names all all referenced in upper case(even though the message insists this shouldn't be an issue)

My table :

mysql> describe CLIENT;
+------------------+--------------+------+-----+---------+----------------+
| Field            | Type         | Null | Key | Default | Extra          |

Snippet of my domain entity :

@Id
@GeneratedValue
@Column(name="ID")
private Integer id;

Snippet of test date I'm trying to force DBUnit to use:

<dataset>
  <CLIENT ID="-1"
    ADDRESS1="Endeavour House"
    ADDRESS2="Russell Rd"
    COUNTRY="England"
    COUNTY="Suffolk"
    MAINPHONENUMBER="0845 606 6067"
    NAME="Suffolk County Council"
    POSTCODE="IP1 2BX"
    SECTOR="Local Government"
    TOWN="Ipswich"
    WEBSITEURL="www.suffolk.gov.uk"/>
</dataset>

I can't think of anything else to try, have dropped tables and recompiled java code, any ideas?

回答1:

Aren't you trying to put to database Client with ID already set? ID column is read-only, only database can "write" to it.

回答2:

I have fixed the error by adding the mentioned column to my entity.

回答3:

I've also had this problem after adding a column to one of my entities (using an in-memory HSQL database).

I managed to solve this problem by simply deleting the temporary files that had previously been generated: mem:testdb.log, mem:testdb.properties and mem:testdb.script

Why did this error occur? => A database schema is stored in the mem:testdb.script file and is not re-generated when the entity is modified.

I ran into the same error, fortunately we had some other test written earlier and found that in most of the tutorials the format the way the xml is written is for the FlatXMLDataSet if you are using XML data set then the correct version is as follow checkout the link at the bottom for more information.

it should be in following format.

<?xml version="1.0" encoding="UTF-8"?>
<dataset>
    <table>
        <column>id</column>
        <column>name</column>
        <column>department</column>
        <column>startDate</column>
        <column>endDate</column>
        <row>
            <value>999</value>
            <value>TEMP</value>
            <value>TEMP DEPT</value>
            <value>2113-10-13</value>
            <value>2123-10-13</value>
        </row>
    </table>
</dataset>

One more time I faced this error in another project, we have a hierarchy of model class, some how hibernate used to create a table Role with 7 columns but while running it with DBUnit it was unable to create the columns(Only 5 were created) hence it was throwing this error, Solution : Manually created this table and 3 more relationship tables which were not created by hibernate.

this error goes away with mysql and hsql if you make format = flat
