问题 I need to execute the command . /home/db2v95/sqllib/db2profile before I can import ibm_db_dbi in Python 2.6.

问题 I trying to configure an XA DB2 DataSource, xa-datasource (based on http://community.jboss.org/wiki/SetUpADB2Datasource) using com.ibm.db2.jcc.DB2XADataSource class ( local-tx-datasource works using the com.ibm.db2.jcc.DB2Driver ).

问题 I am trying to use the data analysis tool Pandas in Python Language. I am trying to read data from a IBM DB, using ibm_db package. According to the documentation in Pandas website we need to provide at least 2 arguments, one would be the sql that would be executed and other would be the connection object of the database. But when i do that, it gives me error that the connection object does not have a cursor() method in it. I figured maybe this is not how this particular DB Package worked. I

问题 I may be wrong, but it seems to be different opinions in the interwebs about what these are. SQL Server, MySQL, DB2, and PostgreSQL show different definitions for these tables. After reading a ton from different vendors (database manuals, user posts, etc.) I was able to distinguish three types of tables of interest (there are many, many more types of no interest for this question). Please bear with me: Heap Table : All rows are stored (probably unordered) in the heap table. Each row has an

问题 I need to find and clean up line breaks, carriage returns, tabs and "SUB"-characters in a set of 400k+ string records, but this DB2 environment is taking a toll on me. Thought I could do some search and replacing with the REPLACE() and CHR() functions, but it seems CHR() is not available on this system (Error: CHR in *LIBL type *N not found). Working with \t, \r, \n etc doesn't seem to be working either. The chars can be in the middle of strings or at the end of them. DBMS = DB2 System =

问题 We are currently using VARCHAR for storing text data in DB2 however we are hitting the problem that length of VARCHAR specified is not the same as length of text because in DB2 VARCHAR length specified is UTF-8 data length which can vary depending on stored text data. For example some texts contain characters from different languages and because of it some texts with 500 characters can't be saved in VARCHAR(500) and etc. Now we are planning to migrate to VARGRAPHIC. I need to know what are

问题 I have already installed IBM DB2 Database Express on Windows 7 Pro. Now, I would like to create my C# code in order to select/insert/update records in DB2 tables. I spend the whole day searching over the internet for links on how to install either OLEDB or ODBC Driver in order to connect to DB2 database. But without success!!! So, i'm wondering if somebody can help me or send me a useful link to download driver. Thank you 回答1: Download: In the webpage: http://www-933.ibm.com/support
