Configuration of freetds driver

In Linux systems the driver version must be set in freetds.conf file to the right use of charset pages., _(*8)

The file is usualy found in /etc/freetds/freetds.conf. Set the configuration at global section as the following example:, _(*9)

[global]
    # TDS protocol version
    tds version = 5.0

Configuring the charset conversion

This package offers to method to charset conversion, it can be converted in application layer or in database layer, we offered both methods because it can be useful for debugging, to config the application layer conversion you need to set up the following entries on the database.php file. You can view an example of the application encoding setup below:, _(*10)

'sybase' =>
    [
        'application_encoding' => true,
        'application_charset' => '',
        'database_charset' => ''
    ],

To use the database layer conversion add the property charset to connection configuration on the sybase configuration array, _(*11)

     'charset' => 'utf8',

Configuring the cache

As the library consults table information whenever it receives a request, caching can be used to avoid excessive queries, _(*12)

To use the cache, add the property cache_tables to the database.php connection configuration, you can customize the time of the cache with the property cache_time in the same configuration, _(*13)

        'cache_tables' => true,
        'cache_time' => 3600

Setting to use numeric data type

In the migration file you must replace use Illuminate\Database\Schema\Blueprint; with use Uepg\LaravelSybase\Database\Schema\Blueprint;. See the following example:, _(*14)

<?php

use Illuminate\Support\Facades\Schema;
// use Illuminate\Database\Schema\Blueprint;
use Uepg\LaravelSybase\Database\Schema\Blueprint; // or "use UepgBlueprint as Blueprint"
use Illuminate\Database\Migrations\Migration;

class CreateTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('table_name', function (Blueprint $table) {
            $table->numeric('column_name', length, autoIncrement);
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('table_name');
    }
}
