Basic Usage

Init using Database name, Table names and Column names. After that, you can do all kinds of CRUD ( Create, Read, Update, Delete ) operations.

Add as many tables and columns you want using these simple codes.

Initialize the Database and the Tables

static Future<Database> init({ String dbName = 'demo.db', int version = 1, List<DbTable> tables })
DbTable(String tableName, {List<DbColumn> dbColumns})
DbColumn(String columnName, {String columnDataType = " TEXT "})

Suppose, we're trying to create a database of two tables named People and Test, each containing three columns. So, we'll write:

EasiestDb.init(dbName: "Data", version: 1, dbTables: [
    DbTable("People", dbColumns: [
      DbColumn('Col 1'), // Default data type is TEXT
      DbColumn('Col 2'),
    ]),
    DbTable("Test", dbColumns: [
      DbColumn('Col 3'),
      DbColumn('Col 4', columnDataType: "TEXT UNIQUE"),
    ]),
  ]);

Look carefully, we didn't add any ID primary key column. That's because easiestdb library does it by default for each table.

Also, you may add as many SQL Constrains in columnDataType parameter. By default, its set to TEXT.

Add data

static Future<int> addData(int tableIndex, List<Datum> data)
Datum(int columnIndex, String value)

Add data in the 1st(0) table:

EasiestDb.addData(0, [
    Datum(1, "AAA"),
    Datum(2, "123"),
]).then((id) {
    print("ID: $id");
});

To pass anything other than string in addData function, you can just convert them to String and pass it ( may be by using yourValue.toString() )

Get All data from a table

static Future<List<Map<String, dynamic>>> getAllData(int tableIndex, {bool ascending = true})

Get all data from the 1st(0) table ( all the indexes start from 0 )

EasiestDb.getAllData(0).then((listMap) {
    listMap.forEach((map) {
        print("${map.values.elementAt(0)}"); // Showing the value of the ID column
        print("${map.values.elementAt(1)}"); // Showing the value from another column
    });
});

Get one data

static Future<List<Map<String, dynamic>>> getOneRowData(int tableIndex, int rowId)

Get data from the 1st(0) table and the 7th(7) row ( all the indexes start from 0 but the rowId starts from 1 )

EasiestDb.getOneRowData(0, 7).then((listMap) {
    listMap.forEach((map) {
        print("${map.values.elementAt(0)}"); // Showing the value of the ID column
        print("${map.values.elementAt(1)}"); // Showing the value from another column
    });
});

Search data

static Future<List<Map<String, dynamic>>> getRowsByMatchingColumnData(int tableIndex, int columnIndex, var valueToMatch, {bool ascending = true})

Searching data in 1st(0) table in the 2nd(1) column by a value:

EasiestDb.getRowsByMatchingColumnData(0, 1, 'AAA').then((listMap) {
    listMap.forEach((map) {
        print("${map.values.elementAt(0)}"); // Showing the value of the ID column
        print("${map.values.elementAt(1)}"); // Showing the value from another column
    });
});

Update data in a row

static Future<int> updateOneDataById(int tableIndex, int rowId, List<Datum> data)
Datum(int columnIndex, String value)

Update data in the first table (0), 7th(7) row:

EasiestDb.updateOneDataById(0, 7, [
    Datum(1, "F F F F F F "),
    Datum(2, "G G G G G G "),
]).then((count) {
    print("Count: $count");
});

Delete one row data

static Future<int> deleteOneData(int tableIndex, int rowId)

Delete the 7th(7) row from the 1st(0) table:

EasiestDb.deleteOneData(0, 7).then((val) {
    print("Count: $val");
});

Delete a row if value matches in a column

static Future<int> deleteDataBySearchingInColumn(int tableIndex, Datum datum)
Datum(int columnIndex, String value)

Delete a one/more data from the first table if matches value in the 2nd(1) column:

EasiestDb.deleteDataBySearchingInColumn(0, Datum(
    1, "F F F F F F "
)).then((val) {
    print("Count: $val");
});

Delete all data from a table

static void deleteTable(int tableIndex)

Delete/Drop the 2nd(1) table:

EasiestDb.deleteTable(1);

Delete the all data from the database

static void deleteDatabase()

Delete/Drop the whole database:

EasiestDb.deleteDatabase();

Run custom SQL commands

static Database getDatabaseObject()

And last but not the least, if you're trying to do something but there's no a function/method created for that command, you can always get the database object and run any custom command like below:

EasiestDb.getDatabaseObject().execute(sqlCommand)

But if you really want that function implemented in easiestdb library, you can:

  1. fork the repo
  2. create a new branch by your github username
  3. add the code
  4. commit + push
  5. make a pull request.

You're welcome...
