Question

我正在尝试用java在Oracle DB中创建一个表。当我运行这个时，我收到错误

ORA-00900：无效的SQL语句

调用中的无效参数

我不知道如何解决这个问题，我所有的研究都是空洞的。

package Project2;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class Embedded {

private static String dbURL = "jdbc:oracle:thin:@query.engr.uconn.edu:1521:BIBCI";
private static Connection conn = null;
private static Statement stmt = null;

public static void main(String[] args) {
    createConnection();
    createTable();
    //insertValue();
    shutdown();
}

private static void createConnection() {
    try {
        Class.forName("oracle.jdbc.OracleDriver").newInstance();
        //Get a connection
        conn = DriverManager.getConnection(dbURL, "cse4701", "datamine");
    } catch (Exception except) {
        except.printStackTrace();
    }
}

private static void createTable() {
    //String sql = "CREATE TABLE IG_READY (PatientId VARCHAR(20), APC integer, TP53 integer, KRAS integer, PIK3CA integer, PTEN integer, ATM integer, MUC4 integer, SMAD4 integer, SYNE1 integer, FBXW7 integer, Status integer)";
    try {
        stmt = conn.createStatement();
        stmt.executeQuery("creat table CRCDB.IG_READY (PatientId VARCHAR(20), APC integer, TP53 integer, KRAS integer, PIK3CA integer, PTEN integer, ATM integer, MUC4 integer, SMAD4 integer, SYNE1 integer, FBXW7 integer, Status integer, PRIMARY KEY (PatientId));");
        //stmt.executeQuery("use CRCDB");
        stmt.close();
    } catch (SQLException e) {
        System.out.println(e.getMessage());
    }
}

private static void shutdown() {
    try {
        if (stmt != null) {
            stmt.close();
        }
        if (conn != null) {
            DriverManager.getConnection(dbURL + ";shutdown=true");
            conn.close();
        }
    } catch (SQLException sqlExcept) {
        System.out.println(sqlExcept.getMessage());
    }
}

}

错误在于你的sql语句

  stmt.executeQuery("creat table CRCDB.IG_READY (PatientId VARCHAR(20), APC integer, TP53 integer, KRAS integer, PIK3CA integer, PTEN integer, ATM integer, MUC4 integer, SMAD4 integer, SYNE1 integer, FBXW7 integer, Status integer, PRIMARY KEY (PatientId));");

你误解了“创建表格”

首先执行带有小测试表的stmt，然后创建表

我希望这可以帮助你解决问题，如果我得到任何其他信息，我肯定会告诉你
