## Installation
check out the [pub.dev](https://pub.dev/packages/easiestdb) for updated installation instructions
## 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 init({ String dbName = 'demo.db', int version = 1, List tables })`
###### `DbTable(String tableName, {List 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 addData(int tableIndex, List 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: $id");
});
```
To pass anything other than `string` in `addData` function, you can just convert them to String and pass it ( may be by using `yourValue.toString()` )
## Get All data from a table
###### `static Future>> getAllData(int tableIndex, {bool ascending = true})`
Get all data from the 1st(0) table ( all the indexes start from 0 )
```
EasiestDb.getAllData(0).then((listMap) {
listMap.forEach((map) {
print("${map.values.elementAt(0)}"); // Showing the value of the ID column
print("${map.values.elementAt(1)}"); // Showing the value from another column
});
});
```
## Get one data
###### `static Future>> getOneRowData(int tableIndex, int rowId)`
Get data from the 1st(0) table and the 7th(7) row ( all the indexes start from 0 but the rowId starts from 1 )
```
EasiestDb.getOneRowData(0, 7).then((listMap) {
listMap.forEach((map) {
print("${map.values.elementAt(0)}"); // Showing the value of the ID column
print("${map.values.elementAt(1)}"); // Showing the value from another column
});
});
```
## Search data
###### `static Future>> getRowsByMatchingColumnData(int tableIndex, int columnIndex, var valueToMatch, {bool ascending = true})`
Searching data in 1st(0) table in the 2nd(1) column by a value:
```
EasiestDb.getRowsByMatchingColumnData(0, 1, 'AAA').then((listMap) {
listMap.forEach((map) {
print("${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 updateOneDataById(int tableIndex, int rowId, List 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 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 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...
