選擇Oracle Java-ORA-00905：未找到關鍵字

Question

我正在嘗試在銀行中進行連接測試並提取一些信息，請認真研究，但是我遇到了以下錯誤：

    Exception in thread "main" java.sql.SQLException: ORA-00905: 
not found keyword

        at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
        at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:331)
        at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:288)
        at oracle.jdbc.driver.T4C8Oall.receive(T4C8Oall.java:743)
        at oracle.jdbc.driver.T4CStatement.doOall8(T4CStatement.java:207)
        at oracle.jdbc.driver.T4CStatement.executeForDescribe(T4CStatement.java:790)
        at oracle.jdbc.driver.OracleStatement.executeMaybeDescribe(OracleStatement.java:1039)
        at oracle.jdbc.driver.T4CStatement.executeMaybeDescribe(T4CStatement.java:830)
        at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1132)
        at oracle.jdbc.driver.OracleStatement.executeQuery(OracleStatement.java:1272)
        at Principal.Principal.main(Principal.java:46)

當我使用簡單的select運行代碼時，例如select * from plan; 它完美地工作。

我該如何解決此錯誤代碼，並且有一種更簡單的方法可以在oracle數據庫中執行選擇，或者此代碼就足夠了？

我想運行查詢以顯示島上的所有列值1（ICCID）。

package Principal;
import java.sql.*;


public class Principal {

         public static void main(String[] args) throws Exception {

                   Connection conexao = ObterConexao();

                   Statement statement = conexao.createStatement();


                   String query = "SELECT a.rp_package_value AS ICCID, "
                           + "c.rrs_resource_value AS IMSI, "
                           + "  ( "
                                + "  CASE "

                   ResultSet resultSet = statement.executeQuery(query);


                   if (resultSet.next()) {

                            System.out.println(resultSet.getObject(2));

Answer 1

您在這一行中有一條SQL注釋：

+ "AND (SUBSTR (c.rrs_resource_value, 6, 2) <> '00') -- valida se o HLR existe "

問題在於Java代碼不知道SQL代碼中的任何換行符，因此會忽略“-”之后的所有內容。 只需將此行更改為：

+ "AND (SUBSTR (c.rrs_resource_value, 6, 2) <> '00') "

Answer 2

正如Volodymyr Pasechnyk指出的那樣 ，問題出在SQL查詢中。

您可以從查詢中刪除注釋，也可以將注釋從--更改為將注釋的代碼包裝在/*和*/ 。

所以改變：

+ "AND (SUBSTR (c.rrs_resource_value, 6, 2) <> '00') -- valida se o HLR existe "

至

+ "AND (SUBSTR (c.rrs_resource_value, 6, 2) <> '00') /* valida se o HLR existe */ "

並更改：

+ "--AND a.rp_package_value like '89955053110002178148' "

至

+ "/*AND a.rp_package_value like '89955053110002178148'*/ "
