问题 I would like to know the quantity of logs used (active logs) by each connection in the database. I know how to retrieve the quantity of active logs for the database, but not for each application. Knowing the quantity of active logs in the database helps me to identify if a log-full condition is approaching. However, I want to know which application is approaching to this condition of log-full. For this reason, I need to know how much log is used by each transaction (each application), but I

问题 Good day everyone! I need to get info from stored procedures in IBM DB2 database on remote server.

问题 I have to implement a partitioning for the column data ( Column Name : ID ) for a very large database table ( DB2 ). Table has more than a billion rows and keeps growing. Partitioning has to be implemented like illustrated here i.e. I have to calculate minId & maxId for a specified range. ID column values are unique but not sequential so simple approach as illustrated in above link will not work - i.e. starting from an ID then keep adding range. WITH ROWNUMTAB AS ( SELECT ROWNUM, ID FROM (

问题 I designed below query for my delete operation. I am new to SQL and just wanted to check with experienced people here if it is fine or any better way to do this. I am using DB2 database DELETE FROM TableD WHERE B_id IN ( SELECT B.B_id FROM TableB tB INNER JOIN TableA tA ON tB.A_id = tA.A_id WHERE A_id = 123 ) AND C_id IN (1,2,3) This has two IN clause which I am little worried and not sure if I could use EXISTS clause anywhere. Database Structure as below: Table A has ONE TO MANY relation

问题 I have a MS Query connection from Excel 2016 sheet to IBM DB2 database. I use parameterized query and link parameter values to Excel cell. While "singular value" clauses such as = < > like work, I can't get IN clause to work with multiple values but otherwise super simple query. Here's a simple demo dataset how I produce the parameter values: Column D formula is =IF(C2>5,A2&",","") which checks column C value for higher than 5 and populates ID in column D if TRUE . I'm expecting to use a

问题 I would like your help about this graph which I have.I would like to find a way how write a script to create a table named COMPS to represent this component/subcomponent tree structure, as an edge list for the graph. I can use these names for the columns of the table COMPONENT, SUBCOMPONENT, SUBCOMPCOUNT. Any ideas? Components of type b occur in more than one place in the structure of component a. But the structure of component b is the same, regardless of its position Component d also occurs
