db2

问题 I have a python program that calls a stored procedure from db2 database. I am using results = cursor.fetchall() to process the results of my stored procedure. However, my stored procedure returns two cursors. results only contains the first one. I need a way to loop through as many cursors as I want. I was hoping fetchmany() would be my answer but it is not. I need to be able to do multiple result sets as the program I am writing can only call one stored procedure. It would take a lot to go

问题 I'm trying to connect to IBM DB2 database with C# application. At first I've installed IBM Data Server Driver Package , which, according to the documentation is for applications using ODBC, CLI, .NET, OLE DB, PHP, Ruby, JDBC, or SQLJ, use IBM Data Server Driver Package . Then I thought I could use IBM.Data.DB2 assembly and happily connect. It didn't work at all, as the app kept crashing while looking for db2app.dll in its current working directory. Then I installed IBM Data Server Client ,

问题 The title is very descriptive i think... My scenario is the next. I need to put the result of a result set (for example a result set with 6 columns and variable rows) from a stored procedure in some temporary table to make some operations over this new table. I find some examples in the web but nothing in DB2... The big problem is how to populate that new table with the restult set of a called stored procedure 回答1: DECLARE GLOBAL TEMPORARY TABLE probably accomplishes what you want. You can

问题 I have a OdbcDataReader that gets data from a database and returns a set of records. The code that executes the query looks as follows: OdbcDataReader reader = command.ExecuteReader(); while (reader.Read()) { yield return reader.AsMovexProduct(); } The method returns an IEnumerable of a custom type ( MovexProduct ). The convertion from an IDataRecord to my custom type MovexProduct happens in an extension-method that looks like this (abbrev.): public static MovexProduct AsMovexProduct(this

问题 Oracle and SQL server have a database change notification feature that notifies table/row level changes in a database to registered clients. The feature is mostly used for synchronization of data with other data sources. I've been looking for this feature in DB2 but so far, no luck. Does DB2 not provide this feature at all or am I missing something? 回答1: There is no such feature out of the box, not in the LUW version anyway (since you reference Oracle and MS SQL Server, I guess that's what

问题 For some reason (I have no control over this) dates are stored as Integers in an iSeries AS400 DB2 system that I need to query. E.g. today will be stored as: 20,171,221 Being in the UK I need it to be like the below in Date format: 21/12/2017 This is from my query: (OAORDT = date field) Select Date(SUBSTR( CHAR( OAORDT ),7,2) ||'/' || SUBSTR(CHAR ( OAORDT ),5,2) || '/' || SUBSTR(CHAR (OAORDT ),1,4)) AS "Order Date" from some.table However, all I get is Nulls. If I remove the Date function,

问题 Although in Oracle DB its is allowed to parametrize the number of rows that the query can fetch by adding to the query: select ... from ... where ... and rownum <= @MaximumRecords I can't add similar condition to acuivalent query running in DB2 : It is allowed to add: select ... from ... where ... fetch first 500 rows only (where there is fixed number of rows) but not: select ... from ... where ... fetch first :1 rows only (:1 == @MaximumRecords) Is someone aware of a solution/work-around to

问题 We have an application on IBM WebSphere Application Server 7.x and it connects to a remote database on z/os DB2 10.x. For annual operation, DB2 shut down and restarted.

问题 Im using DB2 on server and my application connects directly to that server. As data provider i use v9.7 FP5 ibm data server driver and visual studio addins.

Cant i just include some provider DLLs into ClickOnce package and update them only on the computer that is deploying
