Creating stored procedure in SQLite
(6 answers)
Closed 8 years ago.
I want to add a stored procedure that will return a result set with after passing 6 parameters in, in Sqlite. How can I go about it?
SQLite does not have stored procedures.
As an embedded database, SQLite has no client/server communication overhead, and is designed to be used together with a 'real' programming language.
Write the procedure in that language.

I have a personal, non-CRAN, R package. Its purpose is reduce the amount of repeated wrangling I need to do. The data must be pulled from sql server. This pull from SQL is done weekly. Where should I put my sql file and where should I put the R code that does a scheduled weekly sql pull?
You will need to make a chron task which will load the package, pull the data (see here) and recompile the package.
Do you mean you use SQL to pull data from somewhere? What is your data source? Or do you mean you write SQL to create data?
Without knowing the specific, you have 2 options:
1. You could use RODBC package and use sqlQuery() e.g.
Data<- sqlQuery(odbcDriverConnect(...),paste("SELECT
*
FROM DTtest;"))
to 'call' your data from your data source using SQL. More information you can find: https://www.statmethods.net/input/dbinterface.html
This way, you do not need to worry about where to save your sql file (I assume you mean the data). In this case, you only need to make sure your working directory is properly linked to your R script or at least where your R output wants to be in.
Assuming, you have a SQL script to pull data from somewhere else, you can windows scheduler or any types of scheduler to schedule and run the script and make the output saved in one folder where you also use R to grab the data from that directory.

Sounds like a basic question but I couldn't seem to find it.
Is there a way to define in SQLite a column which will be a single bit?
No.
SQLite does not have a separate Boolean storage class. Instead, Boolean values are stored as integers 0 (false) and 1 (true).

AS at 2021-01-20, I should say YES, you can define bit datatype in SQLite and it's working.

The problem is that my dll deals with encryption and the key is stored in constant variable. I want the key to be difficult to get. I understand that there's no way to hide it completely, but I hope there's a way to make it difficult to get the key. What could you suggest?
Thank you for your help!
What you are after is specifically tool that is capable of doing "String Obfuscation"
