sybase

I have 200K rows to be inserted in one single database table. I tried to use jdbcTemplate.batchUpdate in spring in order to do insertion 10,000 per batch. However, this process consumes too much time (7 mins for 200K rows). So on database side, I check the number of rows inserted by select count(*) from table_X . I found the number of rows increased slightly instaed of 10K expected. Can anyone explain what's reason or is it something which should be configurated on Database side ? PS: I am using sybase .... Sanka There are lot of approaches available on the web. Performance directly depends on

I have a single process that queries a table for records where PROCESS_IND = 'N', does some processing, and then updates the PROCESS_IND to 'Y'. I'd like to allow for multiple instances of this process to run, but don't know what the best practices are for avoiding concurrency problems. Where should I start? The pattern I'd use is as follows: Create columns "lockedby" and "locktime" which are a thread/process/machine ID and timestamp respectively (you'll need the machine ID when you split the processing between several machines) Each task would do a query such as: UPDATE taskstable SET

I have this query: SELECT Field1, OrderFor, Writeback, Actshipdate, Orderstatus, receivedate, receivetime FROM orderinfo, shippinginfo WHERE orderinfo.orderid = shippinginfo.orderid AND shippinginfo.custid = '37782' AND receivedate = DATE(NOW()) AND receivetime = ??????? I am using Sybase adaptive server anywhere and trying to get records for the last hour. try this !! SELECT Field1, OrderFor, Writeback, Actshipdate, Orderstatus, receivedate, receivetime FROM orderinfo, shippinginfo WHERE orderinfo.orderid = shippinginfo.orderid AND shippinginfo.custid = '37782' AND receivedate = DATE(NOW())

首先判断错误为页损坏或者索引损坏，根据 Adaptive Server failed to retrieve a row via its RID in database 'escourt5' because the requested RID has a higher number than the last RID on the page. Rid pageid = 0x1c88a8; row num = 0x27. Page pointer = 0x261CA000, pageno = 1869992, status = 0x1, objectid = 8 , indexid = 0, level = 0. 判断其中 :objectid = 8 表示日志段有问题 解决方法一：截断日志 先把 sysdatabases 的 status 修改成 -32768 然后重新启动数据库 1>update sysdatabases set status = -32768 　 where name = "escourt5" 4>go 登陆数据库 1> dump transaction escourt5 with truncate_only 2> go Msg 921, Level 14, State 1: Line 1: Database 'escourt5' has not been

How can I backup my sybase tables and restore using command line? please help me with the command using bcp I have tried using sybase central GUI Thanks. Michael Gardner Since you didn't specify whether you are running on Windows or Unix I'll try to cover both. Unix bcp is located in $SYBASE/$SYBASE_OCS/bin/ Windows bcp is located in %SYBASE%\%SYBASE_OCS%\bin Export bcp DB_NAME..TABLE_NAME out TABLE_NAME.bcp -Sservername -Uusername -Ppassword -[c or n] Choose either -c or -n depending if you want the file to be human readable or not. I recommend using -n unless you have a compelling need to

I'm trying to set up a Sybase query that will give me the following output: Table KeyType KeyNumber Column table1 PK 1 table1_id table1 FK 2 table2_id table1 FK 3 table3_id table1 FK 4 table4_id table1 Unique 5 table1_abc table1 Unique 5 table1_def In other words, I need the PK for each table, and every foreign key it has, as well as every unique key (not where a key has more than one element, such as the unique key above, this is identified by having the same KeyNumber). I'm guessing I need to use sysobject, syscolumns, syskeys and sysconstraints but I can't seem to figure out how they
