如何通过将参数传递给查询来获取函数的值

编程问答 2022-06-09

问题描述

 StringBuilder query = new StringBuilder();

  query.append("SELECT * from Demography Demo")
  .append(" WHERE Demo.Roll IN ( '5','1') AND DemoVer.Roll is null ")
  .append(" AND date(Demo.Updt) between ")
  .append("date('").append("?").append("') AND  CURRENT DATE-100 DAY");

  final Object[] args = new Object[]{getVal()};

  result = jdbcTemplate.query(query,args,new Mapper());

我生成的查询显示“？”仅代替函数中的值

编辑1：它仍然显示吗？而不是价值。我不确定执行查询的代码是否正确。

query.append("SELECT * from Demography Demo")
  .append(" WHERE Demo.Roll IN ( '5','1') AND DemoVer.Roll is null ")
  .append(" AND date(Demo.Updt) between ")
  .append(" timestamp(?)").append(" AND CURRENT DATE-100 DAY");

  final Object[] args = new Object[] {
        getVal() 
    } ; //its returning '2020-09-01 03:00:00'
    int[] types = new int[] { Types.CHAR  };
    List<Record> result = null;  
    result = jdbcTemplate.query(query,types,new Mapper());

生成的查询-

SELECT * from Demography Demo WHERE Demo.Roll IN ( '5','1') AND DemoVer.Roll is null 
   AND date(Demo.Updt) between
   timestamp(?) AND CURRENT DATE-100 DAY

预期查询-

SELECT * from Demography Demo WHERE Demo.Roll IN ( '5','1') AND DemoVer.Roll is null 
   AND date(Demo.Updt) between
   timestamp('2020-09-01 03:00:00') AND CURRENT DATE-100 DAY
