db2

问题 I have issue with creating a proper SQL expression. I have table TICKET with column TICKETID TICKETID 1000 1001 I then have table STATUSHISTORY from where I need to retrieve what was the last time (maximum time) when that ticket entered VENDOR status (last VENDOR status) and when it exited VENDOR status (by exiting VENDOR status I mean the first next INPROG status, but only first INPROG after the VENDOR status, it's always INPROG the next status after VENDOR status). Also it is also possible

问题 I'm getting the error while querying DB2 database 'SQL5193N The current session user does not have usage privilege on any enabled workloads' How should I check if a user has usage permission on workloads? 回答1: To granting the USAGE privilege on a workload. You can use; http://www.ibm.com/support/knowledgecenter/SSEPGG_11.1.0/com.ibm.db2.luw.admin.wlm.doc/doc/t0051489.html To check whether the user has DBADM authority: db2 "SELECT DISTINCT GRANTEETYPE, GRANTEE, DBADMAUTH from SYSCAT.DBAUTH" To

问题 My initial query looks like this: select process_date, count(*) batchCount from T1.log_comments order by process_date asc; I need to be able to do some quick analysis for weekends that are missing, but wanted to know if there was a quick way to fill in the missing dates not present in process_date . I've seen the solution here but am curious if there's any magic hidden in db2 that could do this with only a minor modification to my original query. 回答1: Note: Not tested, framed it based on my

问题 I have a few instances of DB2 10.5 server running on one physical Linux machine, let name them INST1 and INST2. All of them contain multiple schemas, however schema-naming is unique accross whole machine, for example INST1_SCHEMA_A, INST2_SCHEMA_A etc. What I would like to do is to somehow create a user that can access all of those schemas as they were on one instance, so it would be possible to make a queries like: SELECT ID FROM INST1_SCHEMA_A UNION SELECT ID FROM INST2_SCHEMA_A How can I

问题 I trying to implement the example from this manual Generating Unique Values in DB2 Universal Database but encountered the following problem. I've two tables, CREATE TABLE PC_LIST ( PC_ID CHAR(13) FOR BIT DATA NOT NULL, PC_NAME VARCHAR(100) NOT NULL PRIMARY KEY (ID) ); And second table CREATE TABLE PC_DATA ( ID CHAR(13) FOR BIT DATA NOT NULL, PC_ID CHAR(13) FOR BIT DATA NOT NULL, PC_NAME VARCHAR(100) NOT NULL PRIMARY KEY (ID), FOREIGN KEY (PC_ID) REFERENCES PC_LIST(PC_ID) ); I add records to

问题 I have this txt file, formatted with the '|' character between columns, and this script generated by the db2 LOAD wizard: LOAD FROM "<path_and_name_of_the_txt_file>" OF DEL MODIFIED BY ANYORDER COLDEL| METHOD P (1, 2, 3) MESSAGES "<path_and_name_of_a_new_log_file>" REPLACE INTO DB2ADMIN.WEB_NOHAB_CONSOLI (RUC, RAZSOC, FECHA) NONRECOVERABLE INDEXING MODE AUTOSELECT LOCK WITH FORCE; The script just works ok. Now I have to call it from my VFP form (cStatement contains all the LOAD from above):

问题 I'm relatively new to .NET but I'm trying to determine if it's possible to have a single .NET 4 application connect to multiple vendor databases simultaneously (SQL Server, Oracle, DB2 and MySQL) using ADO.NET and execute queries simultaneously? All the examples I've found so far talk about connecting to only one database at a time. Thanks! 回答1: You just need 4 connections strings and 4 separate ADO Connection objects. And then what SLaks said about async queries to do them simultaneously, if

问题 I was trying to write a package file in C for db2. But I was just wondering what all include files and functions can be used. I saw this example in this link by york university. It explains a lot but I don't know what resources are available in terms of include libraries and their functions. Your help is highly appreciated. http://www.eecs.yorku.ca/course_archive/2012-13/W/3421/db2notes/programs/sage.sqc 回答1: Here's a link to the PDF manuals -- see the Application Development section. 来源：

问题 I need to multiply a certain row in a DB2 table 18000 times. Some of the column values will remain as the original and some need to be incremented by 1. I have very little knowledge in DB2 and I just can't find a concrete simple answer on how to do this. Can someone please give me an example on how to achieve this? DB2 version: 9.7 / OS: Windows 2k8 For example I have the following table: T_RES_TABLE Col1 |Col2|Col3 |Col4| ---------------------- 1 | 1| 1| 1| What I need to achieve is: T_RES

问题 We use Flyway as a DB migration tool. Now we want to use it for executing some import statements on our database. In the data are some stored procedures and commands that contain the ";" character. So we wanted to change the delimiter in the sql script. In IBM Data studio I achieved this by following sql code: --#SET TERMINATOR @ insert into "CONTROL"."AP18_ADMIN_RIGHTS" ("REG_ID", "USERNAME") values(12,'testuser')@ --#SET TERMINATOR ; But when I tried to execute this code using flyway I got
