java - 插入负数 - ORA-01722

Question

我正在使用 jdbcTemplate 将一些数据插入到 Oracle 数据库中。不幸的是我收到了这个错误:

java.sql.SQLSyntaxErrorException: ORA-01722: invalid Number

首先，我将字符串转换为 double :

Number number = nmFormat.parse(record[8]);
double doubleVLBalance = number.doubleValue();

之后:

 String sqlSettlementBalance = "INSERT INTO STARR4.TBSETR_SETTLEMENT_BALANCE"+
                "(DT_MOVEMENT,NU_CUSTOMER_REF, NU_MOD_CUSTOMER_REF,"+
                "NU_HIERARCHICAL_NODE, CD_ACQUIRER, CD_PRODUCT,"+
                "CD_BALANCE_TYPE, NU_CUSTOMER, VL_BALANCE, NU_CONTROL)"+
                "VALUES ('" ...,'"+doubleVLBalance+"','"+sb.getNuControl()+"')";

jdbcTemplate.update(sqlSettlementBalance);

字符串record[8]的值为“-0.34”。有什么建议可以解决这个问题吗？

Answer 1

如果用引号将数字括起来，它就会变成字符串。删除引号。

 String sqlSettlementBalance = "INSERT INTO STARR4.TBSETR_SETTLEMENT_BALANCE"+
            "(DT_MOVEMENT,NU_CUSTOMER_REF, NU_MOD_CUSTOMER_REF,"+
            "NU_HIERARCHICAL_NODE, CD_ACQUIRER, CD_PRODUCT,"+
            "CD_BALANCE_TYPE, NU_CUSTOMER, VL_BALANCE, NU_CONTROL)"+
            "VALUES ('" ...,"+doubleVLBalance+",'"+sb.getNuControl()+"')";
