我为使用 Merge 的 Oracle 准备了一个 SQL 查询。但是，当我尝试使用 Java 的 Prepared Statements 时，出现以下错误。

java.sql.SQLSyntaxErrorException: ORA-00923: FROM keyword not found where expected

at ke.co.smart.Switch.serviceProcessor(Switch.java:181)
at ke.co.smart.Switch.run(Switch.java:359)

下面是我准备执行的 SQL 语句。

String sql = "MERGE INTO smart.tmp_switch_membership dest USING (SELECT "
                + membershipNumber + " member," + prevMembershipNumber + "," + schemeCode
                + "," + schemePlan + "," + memberPlan + "," + primaryCareProvider
                + "," + employeeNumber + "," + employerCode + "," + employerDesc
                + "," + brokerCode + "," + brokerDesc + "," + numberOfBeneficiaries.intValue()
                + " FROM DUAL) src ON (src.member = dest.membership_number) "
                + "WHEN NOT MATCHED THEN "
                + "INSERT(membership_number, prev_member_number, scheme_code,"
                + "scheme_plan, member_plan, primary_care_prov, correspondence_ind,"
                + "employee_number, employer_code, employer_desc, broker_agent_code,"
                + "broker_agent_desc, beneficiary_count) "
                + "VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
        PreparedStatement ps = con.prepareStatement(sql);
        ps.setString(1, membershipNumber);
        ps.setString(2, prevMembershipNumber);
        ps.setString(3, schemeCode);
        ps.setString(4, schemePlan);
        ps.setString(5, memberPlan);
        ps.setString(6, primaryCareProvider);
        ps.setString(7, employeeNumber);
        ps.setString(8, employerCode);
        ps.setString(9, employerDesc);
        ps.setString(10, brokerCode);
        ps.setString(11, brokerDesc);
        ps.setInt(12, numberOfBeneficiaries.intValue());
        ps.execute();
        con.commit();
        ps.close();

给予的任何帮助将不胜感激。

SELECT关键字后面没有空格。你应该有空间

"... dest USING (SELECT "
                      ^^^

在这里你也忘记了空格：

 + " FROM DUAL) src ON src.member = dest.membership_number"
            + "WHEN NOT MATCHED THEN"

将其更改为

 + " FROM DUAL) src ON src.member = dest.membership_number "
            + "WHEN NOT MATCHED THEN "
