Question

SqlDataSource chargesDS = (SqlDataSource)lv2Item.FindControl("charges_gv_datasource");
string sql = "WITH relevant_ids AS (SELECT ir.result_id AS relevant_result_id FROM inspection_result_tbl ir WHERE ir.inspection_job_id= '" + incidentID.Text + "') SELECT ir.charge_id, COLLECT(ir.result_id) AS result_ids, ch.charge_progress, ch.claim_verification, ch.hours_allowed, ch.sap_notification, ch.total_checked, ch.charge FROM inspection_result_tbl ir LEFT JOIN relevant_ids ON ir.result_id=relevant_ids.relevant_result_id LEFT JOIN charges_tbl ch ON ir.charge_id=ch.charge_id WHERE ir.charge_id IS NOT NULL GROUP BY ir.charge_id, ch.charge_progress, ch.claim_verification, ch.hours_allowed, ch.sap_notification, ch.total_checked, ch.charge";
                    chargesDS.SelectCommand = sql;

我有一个数据源，我给它上面显示的选择命令，但它给了我错误：

遇到不支持的Oracle数据类型USERDEFINED。

使用堆栈跟踪：

有关如何解决此错误的任何想法？我认为这与COLLECT部分有关。

感谢。

我只是通过替换

来解决这个问题

using System.Data.OracleClient;

带

using Oracle.DataAccess.Client;

您还必须为上述更改添加参考：Oracle.DataAccess
