HSQLDB& DBUnit,在SQL查询

标签: java hsqldb dbunit

我正在使用maven构建项目并收到错误消息:

o.d.database.DatabaseTableMetaData - Cannot find column from ResultSetMetaData             
info via DatabaseMetaData. Returning null.
java.lang.IllegalStateException: Did not find column 'T2_PRF_VALUE' for
<schema.table> 'PUBLIC.CDD_PRF_TABLE4' in catalog 'PUBLIC' because names do
not exactly match

我试图深入研究DBUNIT和HSQLDB驱动程序,并没有找到任何方法来解决此警告。

我的设置是(使用maven):

  

的pom.xml

    <dependency>
        <groupId>org.dbunit</groupId>
        <artifactId>dbunit</artifactId>
        <version>2.5.2</version>
    </dependency>
    <dependency>
        <groupId>org.hsqldb</groupId>
        <artifactId>hsqldb</artifactId>
        <version>2.3.3</version>
        <scope>test</scope>
    </dependency>

hsqldb.script

SET SCHEMA PUBLIC
ALTER USER SA SET INITIAL SCHEMA PUBLIC
ALTER USER SA SET LOCAL TRUE
GRANT DBA TO SA
CREATE SCHEMA PUBLIC AUTHORIZATION DBA
CREATE MEMORY TABLE PUBLIC.CDD_APP_TABLE1 (id INTEGER, value VARCHAR(20));
CREATE MEMORY TABLE PUBLIC.CDD_APP_TABLE2 (id INTEGER, value VARCHAR(20));
CREATE MEMORY TABLE PUBLIC.CDD_APP_TABLE3 (id INTEGER, value TIMESTAMP);
CREATE MEMORY TABLE PUBLIC.CDD_APP_TABLE4 (id INTEGER, value TIMESTAMP);
CREATE MEMORY TABLE PUBLIC.CDD_PRF_TABLE1 (id INTEGER, value VARCHAR(20));
CREATE MEMORY TABLE PUBLIC.CDD_PRF_TABLE2 (id INTEGER, value VARCHAR(20));
CREATE MEMORY TABLE PUBLIC.CDD_PRF_TABLE3 (id INTEGER, value TIMESTAMP);
CREATE MEMORY TABLE PUBLIC.CDD_PRF_TABLE4 (id INTEGER, value TIMESTAMP);
  

query.sql的

SELECT T1.VALUE as T1_PRF_VALUE,
   T2.VALUE as T2_PRF_VALUE
FROM CDD_PRF_TABLE3 AS T1 inner join CDD_PRF_TABLE4 AS T2
ON T1.ID= T2.ID
  

Main.java

final public static String  URL  =  "jdbc:hsqldb:res:hsqldb/hsqldb";
final public static String  DRIVER  =  "org.hsqldb.jdbcDriver";
final public static String  USERNAME  =  "sa";
final public static String  PASSWORD  =  "";
final public static String  SCHEMA_NAME  =  "PUBLIC";

public static JdbcDatabaseTester createHsqldbConnection() throws ClassNotFoundException {
    return new JdbcDatabaseTester(DRIVER, URL,  USERNAME, PASSWORD, SCHEMA_NAME);
}

感谢任何知道如何解决此警告的人。 顺便说一下,我已经看到很多关于这个问题的问题,但没有找到任何好的答案

答案 0 :(得分:0)

不同的JDBC驱动程序返回其ResultSetMetaData.getColumnName(int)调用中的基础列名称或列别名

HSQLDB返回getColumnName(int)调用的基础列名。您可以让HSQLDB返回列别名(如果有),并将连接属性;get_column_name=false附加到连接URL。请参阅指南:
