1.创建Table

CREATE TABLE #CORELIB#.XXHSPHT(

BQSCID_L FOR BQSCID CHAR(30) NOT NULLDEFAULT ' ',

BQMPDT_L FOR BQMPDT DECIMAL(8,0) NOTNULL DEFAULT 0,

XXHSPHT_TCREATE_ROWTS FOR COLUMN BQTMZ1TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,

XXHSPHT_ROW_CHANGE_TS FOR COLUMN BQTMZ2TIMESTAMP GENERATED ALWAYS FOR EACH ROW NO UPDATE AS ROW CHANGE TIMESTAMP NOTNULL,

CONSTRAINT #CORELIB#.XXHSPHT-t_PK_CONSTRAINTPRIMARY KEY(BQSCID,BQMPDT));

Table描述

LABEL ON TABLE #CORELIB#.XXHSPHT IS 'XXX history file');

列名缩写

LABEL ON COLUMN #CORELIB#.XXHSPHT(

BQSCID IS 'SEC       ID                ',

BQMPDT IS 'MARKET          PRICE          DATE');

字段描述

LABEL ON COLUMN #CORELIB#.XXHSPHT(

BASCID TEXT IS 'Security ID      ',

BQMPDT TEXT IS 'Market price date  ',

BQTMZ1 TEXT IS 'Create time   ',

BQTMZ2 TEXT IS 'Chang time   ');

2.创建View

CREATE VIEW #CORELIB#.XXHSPHV1 AS SELECT BQSCID,BQMPDTFROM XXHSPHT;

View描述

LABEL ON TABLE #CORELIB#.XXHSPHV1IS 'XXX history view');

3.游标

定义游标:

EXCE SQL

DECLARECS_XXHSPHV1 CURSOR FOR

SELECTBQSCID,BQMPDT FROM XXHSPHV1

FOR READ ONLY

OPTIMIZE FOR1000ROW

WITH NC;

打开游标:

ECCE SQL

OPEN CS_XXHSPHV1;

ERROR 处理(Return ErrorID:SQSTT)

Get数据:

EXCE SQL

FETCH NEXT FROM CS_XXHSPHV1 FOR 1000ROWS INTO :peData(结构体);

peFetchCount =SQLERRD(3);获取游标内总条数

ERROR 处理(Return Error ID:SQSTT)

关闭游标:

ECCE SQL

CLOSE CS_XXHSPHV1;

ERROR 处理(Return ErrorID:SQSTT)
