Question

我有以下代码运行针对SQL Server数据库的查询。我已经阅读了这些链接

http://jenikya.com/blog/2009/02/sqlexception-select-top-number.html

MS SQL Exception: Incorrect syntax near '@P0'

但我仍然无法看到我在哪里/为什么会收到'@ P0'问题。我把TOP参数包装在括号中。

private String DEP_AMC_QUERY = "SELECT TOP(1) ((fund_amc-reinsurance_premium)/1000)

as dep_amc“+ “FROM Hedging_Staging.dbo.:table”+ “WHERE internal_fund_code_identifier =：fund”+ “AND load_id =：load_id;”;

public BigDecimal getDepAmcValue(String fund,Long load_id,String table){

    NamedParameterJdbcTemplate jdbcTemplate = new NamedParameterJdbcTemplate(getDataSource());

    //Set up parameters
    MapSqlParameterSource namedParameters = new MapSqlParameterSource("fund",fund);
    namedParameters.addValue("load_id",load_id);
    namedParameters.addValue("table",table);
    MapUtils.debugPrint(System.out,"params", namedParameters.getValues());

    //Execute query
    return jdbcTemplate.queryForObject(DEP_AMC_QUERY,namedParameters,BigDecimal.class);
}

控制台和异常消息是

13:11:12,871 INFO  [ReinsuredFundAssetProcessor] looking up dep_amc value for AXX in AI_IFL_Policy table.

params = 
{
    table = AI_IFL_Policy java.lang.String
    fund = AXX java.lang.String
    load_id = 4356 java.lang.Long
} 
13:11:12,909 ERROR [AbstractStep] Encountered an error executing the step

有什么想法吗？

带有SQL Server的NamedParameterJdbcTemplate：'@ P0'附近的语法不正确
