# SQL Server ODBC
* This is a V wrapper of SQL Server ODBC C/C++ library
## Dependencies
* ODBC C/C++ library
* Linux Install:
* Details: https://docs.microsoft.com/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server
* `msodbcsql17` and `unixodbc-dev` packages are needed
* Windows Install:
* `odbc` lib is included in windows sdk for most of distributions,
so there is no need to install it separately
* Details: https://docs.microsoft.com/en-us/sql/connect/odbc/microsoft-odbc-driver-for-sql-server
## Windows Notes
### Using `msvc`
* Make sure `cl.exe` of `msvc` is accessible from command line.
You can run `v` commands in `Visual Studio 2019 Developer Command Prompt` to be safe.
* C Headers and dlls can be automatically resolved by `msvc`.
### Using `tcc`
* Copy those headers to `@VEXEROOT\thirdparty\mssql\include`.
The version number `10.0.18362.0` might differ on your system.
Command Prompt commands:
```cmd
copy "C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\um\sql.h" thirdparty\mssql\include
copy "C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\um\sqlext.h" thirdparty\mssql\include
copy "C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\um\sqltypes.h" thirdparty\mssql\include
copy "C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\um\sqlucode.h" thirdparty\mssql\include
copy "C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\shared\sal.h" thirdparty\mssql\include
copy "C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\shared\concurrencysal.h" thirdparty\mssql\include
```
* dlls can be automatically resolved by `tcc`
## TODO
* Support Mac
* Support ORM
## Usage
```v ignore
import mssql
fn test_example() ? {
// connect to server
config := mssql.Config{
driver: 'ODBC Driver 17 for SQL Server'
server: 'tcp:localhost'
uid: '<your username>'
pwd: '<your password>'
}
mut conn := mssql.Connection{}
conn.connect(config.get_conn_str()) ?
defer {
conn.close()
}
// get current db name
mut query := 'SELECT DB_NAME()'
mut res := conn.query(query) ?
assert res == mssql.Result{
rows: [mssql.Row{
vals: ['master']
}]
num_rows_affected: -1
}
}
```
