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:EasiestSqlLibrary:1.0.0.2'
}

Basic Usage

Steps to follow:

  1. Initialize
  2. Add Tables and Columns
  3. Call doneAddingTables method

After that, you can do all kinds of CRUD ( Create, Read, Update, Delete ) operations.

Initialize the Database and the Tables

EasiestDB.init(Context context)
easiestDB.addTableColumns(String tableName, Column... columns)
easiestDB.doneAddingTables()
EasiestDB easiestDB = EasiestDB.init(this)
                    .addTableColumns("table 1",
                            new Column("Column a1", "text"),
                            new Column("Column a2", "text")
                    )
                    .addTableColumns("table 2",
                            new Column("Column b1", "text"),
                            new Column("Column b2", "text", "unique")
                    )
                    .doneAddingTables();
  • You don't need to add the "ID" primary key column. EasiestSqlLibrary does that by default.

Add data

easiestDB.addDataInTable(int tableIndex, Datum... data)
Datum(String columnName, String value)
Datum(String columnName, int value)
Datum(String columnName, double value)
Datum(int columnIndex, String value)
Datum(int columnIndex, int value)
Datum(int columnIndex, double value)
boolean added = easiestDB.addDataInTable(0,
        new Datum(1, "Value1"),
        new Datum(2, "Value2")
);

Get All data from a table

easiestDB.getAllDataFrom(int tableIndex)
easiestDB.getAllDataFrom(String tableName)
Cursor cursor = easiestDB.getAllDataFrom(0);
if (cursor != null) {
    while (cursor.moveToNext()) {
        int value1 = cursor.getInt(columnIndex);
        String value2 = cursor.getString(columnIndex);
        double value3 = cursor.getDouble(columnIndex);
    }
}

or

easiestDB.getAllDataOrderedBy(int columnIndex, boolean ascending, int tableIndex)
Cursor cursor = easiestDB.getAllDataOrderedBy(0, true, 0);
if (cursor != null) {
    while (cursor.moveToNext()) {
        int value1 = cursor.getInt(columnIndex);
        String value2 = cursor.getString(columnIndex);
        double value3 = cursor.getDouble(columnIndex);
    }
}

Get All data from a row within a table

easiestDB.getOneRowData(int tableIndex, int rowNumber)
easiestDB.getOneRowData(String tableName, int rowNumber)
Cursor cursor = easiestDB.getOneRowData(0, 1); // rowNumber starts from 1 but tableIndex starts from 0
if (cursor != null) {
    cursor.moveToFirst();
    int value1 = cursor.getInt(columnIndex);
    String value2 = cursor.getString(columnIndex);
    double value3 = cursor.getDouble(columnIndex);
}

Search value in a column within a table

easiestDB.searchInOneColumn(int columnIndex, String valueToSearch, int limit, int tableIndex)
easiestDB.searchInOneColumn(String columnName, String valueToSearch, int limit, int tableIndex)
Cursor cursor = easiestDB.searchInOneColumn(1, "Value1", 0, 0);
if (cursor != null) {
    cursor.moveToFirst();
    int value1 = cursor.getInt(columnIndex);
    String value2 = cursor.getString(columnIndex);
    double value3 = cursor.getDouble(columnIndex);
}

Match values in multiple columns. ( Example: Matching ID and password for a user within a table )

easiestDB.searchValuesInMultipleColumns(int tableIndex, Datum... data)
Cursor cursor = easiestDB.searchValuesInMultipleColumns(1,
        new Datum(1, "Value1"),
        new Datum(2, "Value2")
);
boolean matched = cursor.getCount() > 0;

Update data in a row

easiestDB.updateData(int tableIndex, int rowNumber, Datum... data)
boolean updated = easiestDB.updateData(0, 1,
        new Datum(1, "Value1.1"),
        new Datum(2, "Value2.2")
);

Delete one row

easiestDB.deleteRow(int tableIndex, int rowNumber)
boolean deleted = easiestDB.deleteRow(0, 1);

Delete a row if values match in a column

easiestDB.deleteRowIfValuesMatchIn(int tableIndex, Datum data)
easiestDB.deleteRowIfValuesMatchIn(int tableIndex, Datum data)
boolean deleted = easiestDB.deleteRowIfValuesMatchIn(0,
        new Datum(1, "Value1")
);

Delete all data from a table

easiestDB.deleteAllDataFrom(String tableName)
easiestDB.deleteAllDataFrom(int tableIndex)
easiestDB.deleteAllDataFrom(0)

Delete the all data from the database

easiestDB.deleteDatabase()
boolean deleted = easiestDB.deleteDatabase();

I hope, you will enjoy using the library. Feel free to contribute codes.
