Insert BLOB using java for both DB2 and Oracle

阅读更多关于 Insert BLOB using java for both DB2 and Oracle

问题 I am currently validating an application developed on Oracle for DB2. Since we don't want to maintain two separate sources, I need some query to insert blob into a field, that works in both oracle and db2. I don't have any identifier to distinguish under which DB the application is running. I used utl_raw.cast_to_raw in oracle and CAST() as BLOB in DB2 which are mutually incompatible. 回答1: You won't be able to find a common SQL that uses some kind of casting. But you can do this with "plain"

oracle与db2分区的区别

阅读更多关于 oracle与db2分区的区别

ORACLE 和 DB2 都引入了partition的概念.但是区别还是相当大的. ORACLE的分区是表的分区,每张表可以按某一列的值将数据进行组织,索引,和查询.每个分区可以放在不同的表空间里,各分区可以单独操作. DB2的分区是数据库分区,它的每个分区可以视为一个独立的数据库,有自已的后台进程,内存结构和存储磁盘,分区的数据库的每个分区上的表空间是一致的,也就是说,一个分区数据库中的表,就好像把数据分区放在不同的数据库中一样.在分区数据库中建表,如不指定分区键,系统认为表的第一个字段是分区键. 在最新未公开发布的DB2 V9.1中,也支持了表分区的概念,其用法与ORACLE的用法类似. ORACLE 的分区表建表语句: CREATE TABLE product_information ( product_id NUMBER(6) , product_name VARCHAR2 (50) , product_description VARCHAR2(2000) , category_id NUMBER(2) , weight_class NUMBER(1) , warranty_period INTERVAL YEAR TO MONTH , supplier_id NUMBER(6) , product_status VARCHAR2(20) , list_price

Connect PHP to AS400 with ODBC or DB2

阅读更多关于 Connect PHP to AS400 with ODBC or DB2

I'm trying to connect my WEB server to AS400. The web server has not DB2 library neither ODBC library. I have installed XAMPP in my Windows computer, and one of my colleagues also did. He has Client Access on his Computer. We both installed: - XAMPP - ibm_data_server_driver_package_win32_v10.5.exe We tried to install PECL DB2 extension ( LINK ) but unsuccessfully (got error ".\php.exe appears to have a suffix .exe, but config variable php" : seems that nobody has solved this problem on Windows...). Then we saw that XAMPP has the ODBC Module already on it, so we tried to estabilish a connection

问题 I would like to test a DB2 stored procedure running on an AS400 system. I have the IBM System i Access for Windows installed and can run SQL commands against the DB2 database. My question is: What is the syntax to execute a stored procedure that takes in a parameter and returns a result as an output parameter and print the value to the screen? Just to clarify: I am not asking how to call the proc in code. I want to execute the proc and see the results in the gui tool (which is similar to SQL

DB2 9.7 sum 子查询 ErrorCode -112 苦逼的问题

阅读更多关于 DB2 9.7 sum 子查询 ErrorCode -112 苦逼的问题

对于Db2，一直抱有不太友好的态度，果然这两天发生了问题。程序在开发版上能够正常运行，到客户那边却SQL报错。问题如下：表：Test Col1 （int） | Col （varchar 10） 1 | row1 2 | row2 Sql: select sum(Col1 * (select Col1 from Test where (Col1=2) ) from Test 报错： ERRORCODE= -112 几经查证后发现是DB2版本问题，同样的9.7，客户的版本没有安装fix pack. IBM官方资料显示，该问题是在聚合函数里用子查询导致的，该问题在fp4修正。 IC70754: EXTENDING SUPPORT OF SUBQUERY IN AGGREGATE FUNCTIONS http://www-01.ibm.com/support/docview.wss?uid=swg1IC70754 应为客户无法更新版本，所以只有我们找对应版本来验证。官方网站能够下载到的Express-C的版本已经是10.1，如果想下老版本的Express-C，可以从以下Ftp下载。 ftp://ftp.software.ibm.com/software/data/db2/express/db2exc_images/ ps.百度的搜索是在不敢恭维，找了半天没啥发现

Restart initial id of table with using MAX() method

阅读更多关于 Restart initial id of table with using MAX() method

I am doing some changes on my table and I couldn't figure out the problem. This is my SQL script; ALTER TABLE X ALTER COLUMN X_ID RESTART WITH (SELECT MAX(X_ID) FROM X); Altough I used AS instead of WITH and tried other combinations, I couldn't find the exact syntax. (By the way, I cannot set this property in the initialization, I got to do it after creation of the table ) When looking at the syntax for ALTER TABLE you will find that you can only use a constant, e.g., "RESTART WITH 12345". A query itself is not possible. For automation you would need to break it up, use a variable, generate
