A flexible and powerful SQL query string builder for InterSystems IRIS

SQLBuilder

A flexible and powerful SQL query string builder for InterSystems IRIS

Benefits

1. Nice and clean object oriented methods instead of having to use concatenation
and substituition to generate dynamic queries
2. Flexibility to build query adding clauses with logical conditions

Installation

Docker

Open terminal and clone/git pull the repo into any local directory

$ git clone https://github.com/henryhamon/sql-builder.git

Open the terminal in this directory and run:

$ docker-compose build

Run the IRIS container with your project:

$ docker-compose up -d

How to Run the Application

Open InterSystems IRIS terminal:

$ docker-compose exec iris iris session iris
USER>zn "IRISAPP"
IRISAPP>Write ##class(gen.SQLBuilder).%New().Select("name, ssn").From("sample.person").GetSQL()

Examples

Set tRS = ##class(gen.SQLBuilder).%New("sample.person").Where("Age = ?", 30).Execute()

SQL Executed:

Select * From sample.person Where Age = '30'
