QUESTION
In odd/even question if we provide very large value (like up to 12 digits ) then there are error in program;
...ANSWER
Answered 2021-Dec-03 at 23:27The maximum value (a 32 bit) int
can take in C++ is 2,147,483,647. So, 12 digits can't be handled by int
– use long int
or long long int
, instead.
QUESTION
This is the sample request payload that is being sent to insert into the oracle stored procedure:
...ANSWER
Answered 2021-Nov-10 at 11:58You are using the stored procedure operation of the Database connector in a generic way, ie the parameters and the query are passed dynamically. That works for base types, but for arrays and user defined types it requires them to be constructed with special functions Db::createArray() and Db::createStruct(). Also you may need to specify the types in the database connector configuration.
QUESTION
Here I am not able to access the value of the name
outside of the string even if I use other string the value is not initializing.
ANSWER
Answered 2021-Jun-27 at 15:05Your question is not clear. But I hope this will fix it. Be sure to initialize variable n with a value that you want.
QUESTION
I want to set up a RDBMS for structured time series data of limited size (about 6000 series, 50mb of data) at various frequencies (daily, monthly, quarterly, annual CY and annual FY), and I want to run SQL queries on the database (mostly join various tables by time). The database is updated once a month. The variable names of the tables in this database are rather technical not very informative. The raw data is labeled as shown in the table below (example of a monthly table).
I started setting this up in MySQL and figured that just equipping tables with appropriate temporal identifiers gives me the join functionality I want. I could however not find out how to store the variable labels appropriately. Is it possible to somehow add attributes to the columns? Or can I link a table to the table mapping labels to the column names, such that it is carried along in joins? Or should I set this up using a different kind of database? (database must be easy to set up and host though, and SQL is strongly preferred). I am grateful for any advice.
Update: I figured you can add comments to MySQL columns and tables, but it seems these cannot be queried in a standard way or carried along in joins. Is it possible to retrieve the information in the comments along with the queried data from a standard database connector (like this one for the R language: https://github.com/r-dbi/RMySQL)? Below a DDL example for tables with variable labels as comments.
...ANSWER
Answered 2020-Nov-27 at 13:42I would structure your data differently. I would put all your measures in a single table and have a single measure per row. I would then add a DATE table (so that you have the week/month/quarter/year values for each metric date) and a METRIC_TYPE table that holds the labels for each metric code.
By normalising the data like this I think you have a more flexible design and it'll allow you to do what you want.
This is only for illustration of what I mean - it is not meant to be a definitive design:
QUESTION
I am having to use base R and I am only really familiar with ggplot2. I have told R to colour my plot by site, which it has done... but unlike ggplot2 it doesn't automatically give me a legend to tell me which colour it has assigned to which site. Is there either a way to tell R to plot a site in a specific colour or a way to make it create a legend. I tried creating a legend but it seemed I had to input exactly what colour, shape etc should be on the legend which defeats the point.
Thanks.
...ANSWER
Answered 2020-Jun-25 at 13:46Here is an example with the iris data set.
Species would be your Site. You define the color for Species and then build the legend, in which the colors are made with unique(iris$Species))
.
QUESTION
I am calling Stored Proc from Spring Data JPA :
Procedure is:
...ANSWER
Answered 2020-Apr-27 at 10:25Here's what happened:
- you declared a procedure with 3 parameters: 1 in and 2 out
- you said: "Procedure is accepting one parameter and I am also passing 1 argument"
- that was the 1st procedure's parameter (
arg1 IN
) - it results in "PLS-00306: wrong number or types of arguments"
- that was the 1st procedure's parameter (
Of course it does; you need to provide 2 more arguments (datatype should be able to accept VARCHAR2
values returned by the procedure).
QUESTION
I'm trying to call a pretty simple procedure, and if I'm in the Toad editor, it works fine:
...ANSWER
Answered 2020-Jan-08 at 23:14When you specify CommandType.StoredProcedure
, the CommandText
should be the name of the procedure, not a PL/SQL script. The parameter is passed in the Parameters
collection.

Install npls
You can use npls like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
