Merge を使用する Oracle 用の SQL クエリを用意しました。ただし、Java のプリペアド ステートメントを使用しようとすると、次のエラーが発生します。
java.sql.SQLSyntaxErrorException: ORA-00923: FROM keyword not found where expected

以下は、実行のために準備したSQLステートメントです。
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();
与えられた助けに感謝します。
