使用jdbc模板从spring boot调用postgres存储过程[重复]

Question

我正在从 Oracle DB 迁移到 Postgres。我在 oracle 中使用存储过程，并使用 jdbc 模板在我的 Spring Boot 代码中访问它们。使用 postgres 存储过程运行代码时出现错误。这是我的代码的 sn-p：

@Repository
 public class DatabaseImpl implements RegistrationDao {
            @Autowired
            DataSource dataSource;
            private JdbcTemplate jdbcTemplate;
            private SimpleJdbcCall spStoreTempData;

            @PostConstruct
            private void postConstruct() throws SQLException {
                jdbcTemplate = new JdbcTemplate(dataSource);
                spStoreTempData = new SimpleJdbcCall(jdbcTemplate).withProcedureName("stmt_temp_store").withSchemaName("my_schema");
            }

            @Override
            public Map<String, Object> storeTempData(String v_user_type, String v_refid, String v_phone, String v_scode, String v_id_number, String v_email,
                                                     String v_tnc, String v_channel, String v_temp_uuid, String v_totp, String v_totp_expperiod, String v_svc_type, String v_reason, String v_max_retries) {

                SqlParameterSource in = new MapSqlParameterSource()
                        .addValue("v_user_type", v_user_type)
                        .addValue("v_refid", v_refid)
                        .addValue("v_phone", v_phone)
                        .addValue("v_scode", v_scode)
                        .addValue("v_id_number", v_id_number)
                        .addValue("v_email", v_email)
                        .addValue("v_tnc", v_tnc)
                        .addValue("v_channel", v_channel)
                        .addValue("v_temp_uuid", v_temp_uuid)
                        .addValue("v_totp", v_totp)
                        .addValue("v_totp_expperiod", v_totp_expperiod)
                        .addValue("v_svc_type", v_svc_type)
                        .addValue("v_reason", v_reason)
                        .addValue("v_max_retries", v_max_retries)
                        .addValue("v_code", "")
                        .addValue("v_msg", "");

                Map<String, Object> result = null;
                try {
                    result = spStoreTempData.execute(in);
                } catch (Exception e) {
                    System.out.println(e.getLocalizedMessage());
                }
                return result;
            }

}

执行此代码时，我收到以下错误：

CallableStatementCallback; bad SQL grammar [{? = call my_schema.stmt_temp_store(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)}]; nested exception is org.postgresql.util.PSQLException: ERROR: my_schema.stmt_temp_store(numeric, character varying, numeric, numeric, character varying, character varying, character varying, character varying, character varying, numeric, character varying, numeric, character varying, numeric, character varying, character varying) is a procedure
    Hint: To call a procedure, use CALL.

我做错了什么？ Here is a link 使用 oracle db 时代码的工作原理

Answer 1

检查它是Procedure还是Function，如果是function你应该使用

spStoreTempData = new SimpleJdbcCall (jdbcTemplate) .withFunctionName (" name_you_function "). WithSchemaName (" my_schema ");
