Java 插入负数-ORA-01722

我正在使用jdbcTemplate向Oracle数据库中插入一些数据。不幸的是，我遇到了以下错误：

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();

及之后：

 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);

字符串记录[8]的值为“-0.34”。有没有解决这个问题的建议？

如果用引号括起一个数字，它就会变成一个字符串。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()+"')";

如前所述，您应该删除引号，但我建议您

jdbcTemplate.update(sqlSettlementBalance);

使用

jdbcTemplate.update(sqlSettlementBalance, Object... args);

例如，类似这样的事情：

 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 ('"...,?,'"+sb.getNuControl()+"')";

jdbcTemplate.update(sqlSettlementBalance, doubleVLBalance);

PreparedStatement的用法见示例
