使用timesten连接数据库的一大堆乱七八糟的东西

sql

单表无索引单列排序 SELECT * FROM MWT_UD_PD_SB_RH_DLQ ORDER BY XH
单表有索引单列排序 SELECT * FROM MWT_UD_PD_SB_RH_DLQ ORDER BY SCCJ
单表无索引多列排序 SELECT * FROM MWT_UD_SBD_SB ORDER BY XH, YXZT
单表分组 SELECT YXZT FROM MWT_UD_SBD_SB GROUP BY  YXZT
分组排序 SELECT YXZT FROM MWT_UD_SBD_SB GROUP BY  YXZT
ORDER BY YXZT
单表分组求数量 SELECT YXZT,COUNT(*) FROM MWT_UD_SBD_SB GROUP BY YXZT
单表分组过滤 SELECT YXZT,COUNT(*) FROM MWT_UD_SBD_SB GROUP BY YXZT HAVING COUNT(*) < 10
单表分析函数 SELECT COUNT(*) FROM (
SELECT OBJ_ID,CLS_ID,CUSER_ID,
DENSE_RANK() OVER(PARTITION BY OBJ_DISPIDX 
ORDER BY XH) RANK
FROM MWT_UD_PD_SB_RH_JYZ
) WHERE RANK = 1
单表计算 SELECT AVG(OBJ_LOCALID),AVG(SL),SUM(OBJ_DISPIDX)/SUM(SL) 
FROM MWT_UD_PD_SB_RH_JYZ
单表分组计算 SELECT SL,AVG(OBJ_LOCALID),AVG(SL) 
FROM MWT_UD_PD_SB_RH_JYZ GROUP BY SL
单表计算过滤 select OBJ_DISPIDX ,LENGTH(OBJ_DISPIDX) from MWT_UD_SBD_SB where LENGTH(OBJ_DISPIDX) <=4
单表模糊匹配 select * from MWT_UD_SBD_DLFGQ where ZHDQMC like '67CF9F24-FA5E%'
多表联合查询 select * from MWT_UD_PD_SB_RH_JYZ j, MWT_UD_SBD_SB b where j.OBJ_ID = b.OBJ_ID
单表过滤查询 SELECT * FROM MWT_UD_PD_SB_RH_GTJC WHERE OBJ_DISPIDX BETWEEN 192089651 AND 198000000

数据导入：

ttBulkCp -i"DSN=tt_1122;UID=cacheuser;PWD=timesten;oraclePWD=oracle"mw_app.MWT_UD_PD_SB_RH_JYZ /home/tt/test/mwt_ud_pd_sb_rh_jyz.txt

1、  Linux中连接timesten的命令

ttisql "DSN=tt_1122;UID=cacheuser;PWD=timesten;oraclePWD=oracle"

2、  Linux中启动和关闭timesten的命令

启动命令：

ttDaemonAdmin –start –force 或 ttDaemonAdmin –startserver

关闭命令：

ttDaemonAdmin –stop –force 或 ttDaemonAdmin –stopserver
