My Laravel web app uses the schema builder for database portability, so the MySQL-specific YEAR column type is not available.

I want to be able to sort and select rows of data by year (including BETWEEN). What's the best portable column type for storing year values?

What's the best portable column type for storing year values?

smallint is a good choice to represent years, and it's ANSI SQL, so will work in most databases. It will last until the year 32767.

Some databases support create domain which basically lets you create your own types. You could create a year domain for other databases. I prefer the simplicity of smallint for year though.

YEAR Data Type, A database table contains multiple columns with specific data types such as numeric or string. In addition, MySQL also has BIT data type for storing bit values. The Date field has been added as a Column field and grouped by year: Helper column alternative. As an alternative to automatic date grouping, you can add a helper column to the source data, and use a formula to extract the year. Then add the Year field to the pivot table directly. Steps. Create a pivot table; Add Color field to Rows area; Add Color field Values area, rename to "Count" Add Date field to Columns area, group by Year; Change value field settings to show count if needed; Notes

Could you do something like this:

public function up()
{
    Schema::create('mytable', function(Blueprint $table)
    {
        $table->increments('id');
        // columns
        $table->timestamps();
    });

    DB::statement('ALTER mytable ADD year YEAR' );

}

MySQL Data Types Overview, order_items from the sample database for demonstration. Sample Tables. This example uses the YEAR() function to extract year data from the� But I am confused what kind of data type I should use for storing month - year value. Here is what I have considered. Two Integer columns one for year other for month (clear to understand and strong to manipulate (anybody who uses this table can easily use ranges and orders) but I think that would take more space than another solution. Use a

I think this should work:

Schema::table('tablea_name', function(Blueprint $table)
{
    DB::statement('ALTER TABLE table_name ADD year YEAR(4);');
});

Portable solution would be if Laravel provides any way to access this method (in /vendor/laravel/framework/src/Illuminate/Database/Schema/Blueprint.php) in upcoming versions:

/**
 * Add a new column to the blueprint.
 *
 * @param  string  $type
 * @param  string  $name
 * @param  array   $parameters
 * @return \Illuminate\Support\Fluent
 */
protected function addColumn($type, $name, array $parameters = array())
{
    $attributes = array_merge(compact('type', 'name'), $parameters);

    $this->columns[] = $column = new Fluent($attributes);

    return $column;
}

SQL Server YEAR() Function By Practical Examples, To store the date data in the database, you use the SQL Server DATE data type. MM is two digits that represent a month of a year, which ranges from 01 to 12. B) Using DATE to define the table columns example The following INSERT statement illustrates how to insert a row with literal date values into the table:. Introduction to Oracle DATE data type. The DATE data type allows you to store point-in-time values that include both date and time with a precision of one second. The DATE data type stores the year (which includes the century), the month, the day, the hours, the minutes, and the seconds. It has a range from January 1, 4712 BCE through December

As at Laravel 5.8, you can do this:

$table->year('birth_year');

An Essential Guide To SQL Server DATE Data Type, These may include weekdays, holidays, quarters, or time of year. Each subsequent column will be an attribute of that date, where the types and size of As a result, storing calendar data in a permanent location can be an easy solution. through @End_date, as we insert rows into our calendar table. The purpose of these 12 rows is to ensure that when we consider the actual table data there will be no gaps in the 12 columns. This is achieved by using the generated 12 rows as the "from table" in our query, and the "A" table is LEFT JOINED based on the year/month of a date column [some_dt] to the 12 monthly rows.

Designing a Calendar Table, Store temporal data in a row format; Store time values in a date field; Index fields Often you'll have time represented in columns in your attribute table, for instance, This is a special database field type specifically for storing time and date information. For example, yearly data can be stored as 2000, 2001, and so on. When working with a PivotTable, you can display or hide subtotals for individual column and row fields, display or hide column and row grand totals for the entire report, and calculate the subtotals and grand totals with or without filtered items.

Best practices for storing temporal data—Help, Each column in a database table is required to have a name and a data type. data is expected inside of each column, and it also identifies how SQL will interact with the stored data. YEAR, A year in four-digit format. The n parameter indicates whether the field should hold 4 or 8 bytes. float(24) holds a 4 -byte field and� Create a table with hstore data type. We create a table named books that has three columns: id is the primary key that identifies the book. title is 0the title of the products attr stores attributes of the book such as ISBN, weight, and paperback. The data type of the attr column is hstore.

SQL Data Types for MySQL, SQL Server, and MS Access, Storage requirements are given in Section 10.5, “Data Type Storage A bit-field type. The behavior used by the server for DECIMAL columns in a table depends on MySQL displays YEAR values in YYYY format, but permits assignment of to the maximum row size (65,535 bytes, which is shared among all columns)� I was asked to alter a column from CHAR(2) to CHAR(4). You might not think that would be a big deal but it ended up being a big pain. To start with here are a few facts. The table has 1.4 billion rows. The table takes up 750 GB. The database has multiple filegroups each with multiple files. Total size a bit over 2 TB.

Comments
  • How about int? Or, char(4) would also work.
  • Isn't it possible to use raw statements to in the schema builder?
  • This wouldn't be a portable solution.
  • To further my understanding can you tell me what you mean by portable? Do you mean so you can switch between databases so it's not mySql specific for example?
  • This wouldn't be a portable solution.
