Question

我在PostgreSQL数据库中创建了一个包含42列的表。其中五个是bigint类型，而其他类型是character varying类型。然后我尝试使用一些java代码和spring framework中的jdbc库插入数据。

我遇到了一些我需要找到的错误，这很难，因为该表包含很多列 jdbc中要插入该表的语法：

        String sql = "insert into t_reconcile_stage values("
                + " ?::bigint,"             // 1 id 
                + "?::bigint,"              // 2 m_participant_id
                + "?::bigint,"              // 3 m_status_data_id
                + "?,"                      // 4 reconcile_file
                + "?::date,"                // 5 reconcile_date
                + "?,"                      // 6 transaction_date
                + "?,"                      // 7 transaction_time
                + "?::bigint,"              // 8 stan

                + "?::bigint,"              // 24 issuer_fee
                + "?::bigint,"              // 25 biller_fee

                + "?,"                      // 39 free_data10
                + "?::bigint,"              // 40 settlement_amount
                + "?::bigint,"              // 41 charge_amount
                + "?"                       // 42 status
                + ")";                      // 

        simpleJdbcTemplate.update( sql,
                d[0],d[1],d[2],d[3],d4,
                d[5],d[6],d[7],d[8],d[9],
                d[10],d[11],d[12],d[13],d[14],
                d[15],d[16],d[17],d[18],d[19],
                d[20],d[21],d[22],d[23],d[24],
                d[25],d[26],d[27],
                d[28],d[29],d[30],d[31],d[32],d[33],d[34],d[35],d[36],d[37],d[38],
                d[39],d[40],d[41]
        );

我得到的错误：

我不知道错误发生在哪一列。所以我需要使用java中的try-catch语句逐列将数据插入到该表中。是否可以在Postgres中进行INSERT这样的查询？
或者找到该错误的任何其他方法？或者我错过了什么？（我是处理数据库的初学者。）

Answer 1

INSERT是全有或全无操作。插入一个新行，并且需要使用值或NULL（使用显式输入或默认列）分配每一列。所以不，你所要求的是不可能的。

来自Postgres的错误是：

错误：整数的输入语法无效：“”

问题的根源在于您尝试将空字符串作为bigint号出售，这是不可能的。将字符数据转换为整数时，必须将空字符串转换为某种有效形式。 0或NULL（不含引号）。

Answer 2

此错误的一种解决方法是为列指定默认值（但这并非总是很好）。这样，如果你在insert语句中缺少数据，它应该使用默认值。

虽然我建议你设计一个更新方法的修订版，正如上面提到的海报，你的整个问题来自你的数组中的一个值是空的，并且可以通过适当的数据验证来修复。

将数据逐列插入PostgreSQL中的行
