AndroidEasySQL-Library

An Easier & Lazier approach to SQL database for Android

Installation

Add it in your root build.gradle at the end of repositories:

allprojects {
  repositories {
    maven { url 'https://jitpack.io' }
  }
}

Add the dependency

dependencies {
     implementation 'com.github.p32929:AndroidEasySQL-Library:1.3.1'
}

Usage

Steps to follow:

• Initialize
• Set Table Name (Not mandatory)
• Add columns
• Call done method

After that you can do:

• Add data
• Read data
• Edit data
• Delete data
• & more

Code example

Initialization, Set Table Name, Add columns, altogether:

EasyDB easyDB = EasyDB.init(this, "TEST", null, 1) // TEST is the name of the DATABASE
                .setTableName("DEMO TABLE")  // You can ignore this line if you want
                .addColumn(new Column("C1", new DataType()._text_().unique().done()))
                .addColumn(new Column("C2", new DataType()._text_().notNull().done()))
                .addColumn(new Column("C3", new DataType()._text_().done()))
                .doneTableColumn();

You can add as many constraint methods like unique() , notNull() etc. Just, don't forget to call the done() method at the end. See the example above...

addColumn(column)

Column(columnName, dataType)

** Saving the object into a variable will make easier to work with the database later. **

** You don't have to add any primary key. The library does it by default (as ID column) **

Adding data:

You can call the addData() in two ways:

addData(columnNumber, data)

addData(columnName, data)

data parameter in addData() can be either integer or string. After adding all data, call doneDataAdding() method.

columnName is String and columnNumber is integer

Example:

boolean done = easyDB.addData(1, "Data1")
                .addData(2, "Data2")
                .addData(3, "Data3")
                .doneDataAdding();

or

boolean done = easyDB.addData("C1", "Data1")
                .addData("C2", "Data2")
                .addData("C3", "Data3")
                .doneDataAdding();

Thus, it will return a boolean value. True means data added successfully, False means data isn't added successfully.

Showing data:

To get all data as a Cursor object, call getAllData() like this:

Cursor res = easyDB.getAllData();

Later use a while loop like this:

while (res.moveToNext()) {
	// Your code here
}

To get an integer from res call getInt(columnIndex) and to get a String call getString(columnIndex) like this:

int anIntegerVariable = res.getString(columnIndex);
String aStringVariable = res.getString(columnIndex);

here columnIndex is an integer, starts from 0

Example:

while (res.moveToNext()) {
    int anIntegerVariable = res.getString(columnIndex);
    String aStringVariable = res.getString(columnIndex);
}

Update / Edit data:

To update / Edit, call updateData(columnNumber, data) method. Example:

boolean updated = easyDB.updateData(1, "UpdatedData1")
                .updateData(2, "UpdatedData2")
                .updateData(3, "UpdatedData3")
                .rowID(id);

UpdatedData can be either integer or String. Thus, it will return a boolean value. So, you can know if your data is updated or not...

Delete data:

To delete a row data, call deleteRow(rowId) like this:

boolean deleted = easyDB.deleteRow(rowId);

Thus, it will return a boolean value. So, you can know if your data is updated or not...

Delete a table fully:

To delete a table and its all data, call deleteAllDataFromTable like this:

easyDB.deleteAllDataFromTable();

Hope you'll enjoy using the library :)
