SQL查询在代码中工作正常，而不是在测试中

Question

当链接表中的某些列具有某些值时，我正在尝试调用SQL查询（Oracle DB）来更新一个表中的列。我的语法在通用代码中工作正常，但在我的单元测试中，我得到一个“BadSQLGrammarException”：

    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。它似乎不接受“UPDATE（SELECT ...”语法。如果你想要更多这个，这里是查询（列和表名的常量）和使用它的函数：

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);


    }

最后这是我的测试：

@Test     public void testSupprimerRequete（）抛出IOException {

    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，对于我的测试，我使用类似的xml定义的基础，具有相同的结构。

那么我的查询中的问题在哪里？我该如何纠正？或者，如果它是UPDATE的问题（SELECT ...语法，我怎么能有一个类似的查询，它会起作用？ 谢谢。

Answer 1

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=?);

您可以通过这种方式修改查询。
