SQL查询在代码中正常工作，而不是在测试中

我试图调用SQL查询（Oracle数据库）来更新一个表中的列，当链接表中的某些列具有某些值时。我的语法在一般的代码工作正常，但在我的单元测试，我得到一个“BadSQLGrammarException”：SQL查询在代码中正常工作，而不是在测试中

org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [UPDATE (SELECT ex.STATUS FROM BRRS_EXECUTION ex, BRRS_DEMANDE dem WHERE dem.ID_DEMANDE=ex.ID_DEMANDE AND dem.UTILISATEUR=?

SET STATUS=?]; nested exception is org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement "UPDATE ([*]SELECT EX.STATUS FROM BRRS_EXECUTION EX, BRRS_DEMANDE DEM WHERE DEM.ID_DEMANDE=EX.ID_DEMANDE AND DEM.UTILISATEUR=?

显然问题出在括号和选择之间。看起来它不接受“UPDATE（SELECT ...”）语法，如果你想要更多这个，这里是查询（对列和表名称使用常量）以及它使用的函数：

private static final String UPDATE_REQUETE_SAS_SQL = "UPDATE (SELECT ex."+ COL_STATUS + 
     " FROM " + TABLE_BRRS_EXECUTION + " ex, " + TABLE_BRRS_DEMANDE + " dem " 
     + "WHERE dem." + COL_ID_DEMANDE + "=ex." + COL_ID_DEMANDE + " " 
     + "AND dem." + COL_UTILISATEUR + "=:UTILISATEUR " 
     + "AND dem." + COL_PROFIL + "=:PROFIL " 
     + "AND dem." + COL_REGION + "=:REGION " 
     + "AND dem." + COL_REGIME + "=:REGIME " 
     + "AND ex." + COL_ID_EXECUTION + "=:ID_EXECUTION)" 
     + " SET " + COL_STATUS +"=:STATUS"; 

@Override 
    public void deleteRequeteSAS(RequeteSASEntity requeteSASEntity, String user, String region, String profil, String regime) { 
     // affectation des parametres nommés 
     final SqlParameterSource params = new MapSqlParameterSource() 
       .addValue(COL_STATUS, STATUS_SUPPRIME) 
       .addValue(COL_ID_EXECUTION, requeteSASEntity.getIdExecution()) 
       .addValue(COL_UTILISATEUR, user) 
       .addValue(COL_REGION, region) 
       .addValue(COL_PROFIL, profil) 
       .addValue(COL_REGIME, regime); 


     // execution de l'update 
     jdbcTemplate.update(UPDATE_REQUETE_SAS_SQL, params); 


    }

最后，这里是我的测试：

@Test 公共无效testSupprimerRequete（）抛出IOException异常{

String mockUser = "QUAREFMETIER-00001"; 
    String mockRegion = "99"; 
    String mockProfil = "030"; 
    String mockRegime = "01"; 

    List<RequeteSASEntity> listReqInit = new ArrayList<RequeteSASEntity>(); 
    listReqInit.add(requeteSASJdbc1); 
    listReqInit.add(requeteSASJdbc2); 

    requeteSASRepository.deleteRequeteSAS(requeteSASJdbc1, mockUser, mockRegion, mockProfil, mockRegime); 

    assertTrue(!listReqInit.isEmpty()); 
    assertTrue(listReqInit.get(1).getStatus() == 7); 
}

当然我的测试中，我使用了类似的XML定义的基础上，用同样的结构

。

那么我的查询中的问题在哪里，我该如何纠正它？或者，如果它是与更新问题（SELECT ...语法，我怎么能有一个类似的查询这将工作？谢谢。

也许看到https://stackoverflow.com/questions/2334712/how-do-i-update-from-a-select-in-sql-server –

一般来说，你不能从'UPDATE（SELECT ..你必须以'UPDATE TableName ...'开头毕竟，你正在更新表 - 你没有更新你的'select'语句。 –

@DM一些数据库系统（包括SQL标准）考虑子查询是虚拟表，并允许在某些条件下更新此虚拟表。可能在测试中使用的数据库不允许它，而实际的数据库却可以。 –

Update TableName Set COL_STATUS =(
SELECT EX.STATUS FROM BRRS_EXECUTION EX, BRRS_DEMANDE DEM WHERE 
DEM.ID_DEMANDE=EX.ID_DEMANDE AND DEM.UTILISATEUR=? AND DEM.PROFIL=? AND 
DEM.REGION=? AND DEM.REGIME=? AND EX.ID_EXECUTION=?);

您可以用这种方式修改您的查询。

哼，不，它不是同一个查询。当两个表的其他列有给定的条件时，我想将COL_STATUS设置为绝对值（= 7 - >：STATUS）。你们不这样做。 – Djbapt

SQL查询在代码中正常工作，而不是在测试中
