# Microsoft SQL Server connection source codes
Small example console source codes how to connect to the Microsoft SQL Server, how to update rows and how to read the table.
## Running under Windows
1. clone this repository to your computer
2. install the **Microsoft SQL Server** (as a **Docker** container)
3. prepare the user, the table and rows in the database
4. build and run the example **Java** code
5. compile and run the example **.NET C#** code
6. run the example **PHP** code
### 1. Cloning to your computer
- install [GIT] on your computer
- clone this repository to your computer by the GIT command
`git clone https://github.com/petrfaltus/ms-sql-server-connection-source-codes.git`
### 2. Installation of the Microsoft SQL Server (as a Docker container)
- install [docker desktop] on your computer
- refer the [Microsoft SQL Server image]
The subdirectory `docker-database` contains prepared Windows batches:
- `01-run-database.cmd` - pulls the image and runs the container **at the first time**
- `02-switch-database-OFF.cmd` - stops the already existing container
- `02-switch-database-ON.cmd` - starts the already existing container
- `03-inspect-database.cmd` - shows details for already existing container
- `04-exec-connection-to-database-sa.cmd` - executes the **sqlcmd tool** terminal into running database container (as the user *sa*)
- `04-exec-connection-to-database-testuser.cmd` - executes the **sqlcmd tool** terminal into running database container (as the user *testuser*)
- `containers.cmd` - lists currently running containers and list of all existing containers
### 3. Preparing the database
For the connection to the database use either the **sqlcmd tool** terminal or the [Microsoft SQL Server Management Studio]
#### Connection using sqlcmd tool
Use prepared Windows batches, every SQL command terminate by the keyword **GO**
```sql
SELECT @@version;
GO
```
#### Connection using Microsoft SQL Server Management Studio
User *sa* (default password *Syst3mAdm1n!*)
User *testuser* (default password *T3stUs3r!*)
#### SQL lines for sa
```sql
CREATE DATABASE testdb;
USE testdb;
CREATE LOGIN testuser WITH PASSWORD = 'T3stUs3r!';
CREATE USER testuser FOR LOGIN testuser;
GRANT SELECT TO testuser;
GRANT CREATE TABLE TO testuser;
GRANT INSERT TO testuser;
GRANT UPDATE TO testuser;
GRANT ALTER TO testuser;
GRANT EXECUTE TO testuser;
ALTER LOGIN testuser WITH DEFAULT_DATABASE=testdb;
```
#### SQL lines for testuser
```sql
USE testdb;
CREATE TABLE animals (
name VARCHAR(40) NOT NULL,
legs TINYINT NOT NULL,
created DATETIME DEFAULT GETDATE(),
updated DATETIME,
remark VARCHAR(80),
id INT IDENTITY(1,1) PRIMARY KEY NOT NULL
);
CREATE TRIGGER animals_update
ON animals
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;
UPDATE animals
SET updated = GETDATE()
WHERE id IN (SELECT id FROM Inserted)
END;
INSERT INTO animals (name, legs) VALUES ('chicken', 2);
INSERT INTO animals (name, legs) VALUES ('fox', 4);
INSERT INTO animals (name, legs) VALUES ('eagle', 2);
INSERT INTO animals (name, legs) VALUES ('ant', 6);
INSERT INTO animals (name, legs) VALUES ('horse', 4);
CREATE OR ALTER FUNCTION factorial(@n INT) RETURNS INT AS
BEGIN
IF (@n < 0)
RETURN -1;
DECLARE @result INT = 1;
IF (@n < 2)
RETURN @result;
DECLARE @ijk INT = 2;
WHILE @ijk <= @n
BEGIN
SET @result = @result * @ijk;
SET @ijk = @ijk + 1;
END;
RETURN @result;
END;
CREATE OR ALTER PROCEDURE add_and_subtract(@a INT, @b INT, @x INT OUT, @y INT OUT) AS
BEGIN
SET @x = @a + @b;
SET @y = @a - @b;
END;
```
#### optional SQL check lines for testuser
```sql
USE testdb;
SELECT * FROM animals;
SELECT count(*) FROM animals;
SELECT count(*) FROM animals WHERE id!=1;
SELECT dbo.factorial(2);
SELECT dbo.factorial(3);
SELECT dbo.factorial(4);
DECLARE @a INT = 12;
DECLARE @b INT = 5;
DECLARE @x INT;
DECLARE @y INT;
PRINT 'a = ' + CONVERT(VARCHAR(6), @a);
PRINT 'b = ' + CONVERT(VARCHAR(6), @b);
EXECUTE dbo.add_and_subtract @a, @b, @x OUT, @y OUT;
PRINT 'x = ' + CONVERT(VARCHAR(6), @x);
PRINT 'y = ' + CONVERT(VARCHAR(6), @y);
```
### 4. The Java client source code
- install [Java JDK] on your computer
- set the OS environment `%JAVA_HOME%` variable (must exist `"%JAVA_HOME%\bin\java.exe"`)
#### 4.1. Apache Maven
- install [Apache Maven] on your computer
- add the Maven directory (where the batch `mvn.cmd` locates) to the OS environment `%PATH%` variable
The subdirectory `java-maven` contains prepared Windows batches:
- `01-build.cmd` - cleans, compiles and builds the Maven project
- `02-run.cmd` - runs the built Java archive (JAR)
- `03-clean.cmd` - cleans the Maven project
#### 4.2. Gradle Build Tool
- install [Gradle Build Tool] on your computer
- add the Gradle directory (where the batch `gradle.bat` locates) to the OS environment `%PATH%` variable
The subdirectory `java-gradle` contains prepared Windows batches:
- `01-build.cmd` - cleans, compiles and builds the Gradle project
- `02-run.cmd` - runs the built Java archive (JAR)
- `03-clean.cmd` - cleans the Gradle project
### 5. The .NET C# client source code
- use the `csc.exe` .NET C# compiler that is the part of Microsoft .NET Framework (part of OS)
The subdirectory `csharp` contains prepared Windows batches:
- `01-compile.cmd` - compiles the source code (contains the path definition to the `csc.exe` compiler)
- `02-run.cmd` - runs the Windows executable
- `03-clean.cmd` - deletes the Windows executable
### 6. The PHP client source code
- install [PHP] on your computer
- set the OS environment `%PHP_HOME%` variable (must exist `"%PHP_HOME%\php.exe"`)
- install [Microsoft ODBC Driver] (or already installed as a part of [Microsoft SQL Server Management Studio])
- install [Microsoft Drivers for PHP for SQL Server]
- copy `php_pdo_sqlsrv_74_nts_x64.dll` from [Microsoft Drivers for PHP for SQL Server] to the PHP directory `%PHP_HOME%`
To the `php.ini` in the PHP directory `%PHP_HOME%` add lines
```
[PHP]
extension_dir = "ext"
extension=php_pdo_sqlsrv_74_nts_x64.dll
[Date]
date.timezone = Europe/Prague
```
The subdirectory `php` contains prepared Windows batch:
- `01-run.cmd` - runs the code through the PHP interpreter
