SQL 语法异常 - 无效字符，但查询工作正常

【中文标题】SQL 语法异常 - 无效字符，但查询工作正常

【英文标题】：SQL Grammar Exception-Invalid Character, but query working fine

【发布时间】：2018-08-13 07:14:19

【问题描述】：

我写了一个查询，它获取员工的数量，我在 sql developer 中对其进行了测试，它准确且工作正常，但不知何故我在我的 IDE 日志中无缘无故地收到 BadSqlGrammeException

SELECT COUNT(DISTINCT emp_code)
FROM Xxmpcd_Salary_Detail_Table
WHERE Prayas_Erp_Org_Id LIKE '202-%'
AND Yyyymm='201803'
ORDER BY Emp_Name ASC;

IDE 日志

org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [SELECT count(Distinct emp_code)  FROM Xxmpcd_Salary_Detail_Table WHERE Prayas_Erp_Org_Id LIKE '202-%' AND Yyyymm='201803'  Order by Emp_Name ASC;]; nested exception is java.sql.SQLException: ORA-00911: invalid character

JAVA 代码：

public int getNoOfRows(SalaryMigrateSearchParamDTO searchParam) 
    MapSqlParameterSource param = new MapSqlParameterSource();
    String query = "SELECT count(Distinct emp_code) "
            + " FROM Xxmpcd_Salary_Detail_Table ";
    if (searchParam.getCircle() != null && !"".equals(searchParam.getCircle())) 
        query += "WHERE Prayas_Erp_Org_Id LIKE '" + searchParam.getCircle() + "-%' ";
     else 
        query += "WHERE Prayas_Erp_Org_Id LIKE '" + searchParam.getRegion() + "-%' ";
    
    query += "AND Yyyymm='" + searchParam.getYearMonth() + "'  "
            + "Order by Emp_Name ASC ;";
    return getNamedParameterJdbcTemplate().queryForObject(query, param, Integer.class);

请提供解决方案，以便我识别问题，是服务器端出现的问题，我正在使用 Spring MVC 框架开发 Web 应用程序。

【问题讨论】：

请向我们展示发出此查询的 java 代码。

@Tamas 看到我的编辑，我也附加了 java 代码

你测试省略了吗？在 ASC 之后？

可能重复wheres-my-invalid-character-ora-00911

【参考方案1】：

尝试删除语句的最后一个分号（';'）。

【讨论】：

哦..那是工作，我忘了删除最后一个分号，它提出了问题，非常感谢@finqq
