Question

目前我在DAO类中通过JDBC获取postgresql函数数据时遇到问题。连接正在建立。

CallableStatement  mngStatement = conn              
                     .prepareCall("{? = CALL SELECT_SEARCH_DETAILS(?,?,?,?,?,?,?,?)}");

mngStatement.registerOutParameter(1, Types.VARCHAR);
mngStatement.setString(2,abc.getContractNumber());
mngStatement.setString(3,abc.getOrderNumber());
mngStatement.setString(4,abc.getShipmentNumber());
mngStatement.setString(5,abc.getShipmentControlNo());
mngStatement.setString(6,abc.getStatusFromDate());
mngStatement.setString(7,abc.getStatusToDate());
mngStatement.setString(8,abc.getSourceSystem());
mngStatement.setString(9,abc.getDestinationSystem());

mngStatement.execute();
rs  = (ResultSet) mngStatement.getObject(1);

得到如下错误：

org.postgresql.util.PSQLException：格式错误的函数或过程偏移量为1的转义语法。

请帮我解决你的建议。在此先感谢。

功能：

FUNCTION SELECT_SEARCH_DETAILS(
    IN P_CONTARCT_NUM character varying,
    IN P_ORDER_NUM character varying,
    IN P_SHIPMENT_NUM  character varying,
    IN P_SHIP_CON_NUM  character varying,
    IN P_FROM_DATE  character varying,
    IN P_TO_DATE  character varying,
    IN P_SOURCE_SYSTEM character varying,
    IN P_DESTINATION_SYSTEM character varying)
  RETURNS table(CONTRACT_NUMBER text,ORDER_NUMBER text, SHIPMENT_NUMBER text, SCN text, STATUS_CODE text,STATUS_DATE text, LAST_UPDATE_DATE text, SOURCE_SYSTEM text, DESTINATION_SYSTEM text, RFID_FOLLOW_ON_CODE text, UID_INDICATOR text, IVC_SHIPMENT_SEQ_ID text) AS

您不需要CallableStatement。

使用常规PreparedStatement和select语句。

当您的函数返回一个表（“set”）时，您需要使用：

select * from SELECT_SEARCH_DETAILS(...);

所以完整代码如下所示：

PreparedStatement pstmt = conn.prepareStatement("select * from SELECT_SEARCH_DETAILS(?,?,?,?,?,?,?,?)");

pstmt.setString(1, abc.getContractNumber());
pstmt.setString(2, abc.getOrderNumber());
pstmt.setString(3, abc.getShipmentNumber());
pstmt.setString(4, abc.getShipmentControlNo());
pstmt.setString(5, abc.getStatusFromDate());
pstmt.setString(6, abc.getStatusToDate());
pstmt.setString(7, abc.getSourceSystem());
pstmt.setString(8, abc.getDestinationSystem());

ResultSet rs = pstmt.executeQuery();
