react-native-sqlite-tool

This repository is based on react-native-sqlite-storage, you should install and link react-native-sqlite-storage first

Installation

 npm install --save react-native-sqlite-tool

Then follow the instructions to use react-native-sqlite-tool;

Steps

1. Create a class for one table

   import { SqlLite } from "react-native-sqlite-tool";
   //if you use typescript
   export interface T {
       //primary key
       id?: string;
       value?: string;
   }
   //Set primaryKey dbName tableName createTableSql
   class DemoSql extends SqlLite<T> {
       primaryKey = "id";
       dbName = "default.db";
       tableName = "todo";
       createTableSql = `CREATE TABLE IF NOT EXISTS todo (
           id  varchar(32) NOT NULL,
           value varchar(255) DEFAULT NULL,
           PRIMARY KEY (id)
       )`;
       constructor() {
           super();
           //important
           this.init();
       }
   }
      
   export const DemoSqlInstance = new DemoSql();

2. You can use follow apis

   insert(item: T): Promise;

   import { demoSqlInstance } from "./Demo";
   export interface T {
       //primary key
       id?: string;
       value?: string;
   }
   class Todo {
       insert(item: T) {
           return demoSqlInstance.insert(item);
       }
   }

   updateByCondition(newParams: T, conditionParams: T): Promise;

   const item={value:"new value"}
   demoSqlInstance.updateByCondition(item,{id:"123"})

   updateByPrimaryKey(newParams:T): Promise

   const item = { id: "123", value: "new value" }
   demoSqlInstance.updateByPrimaryKey(item);

   deleteByPrimaryKey(primaryValue: any): Promise

   demoSqlInstance.deleteByPrimaryKey("123")

   selectByPrimaryKey(primaryValue: any): Promise<T | null>

   demoSqlInstance.selectByPrimaryKey("123")

   select(selectSql?: string, orderSql?: string): Promise<[] | T[]>

   demoSqlInstance.select()
   demoSqlInstance.select("id=123")
   demoSqlInstance.select("id=123","create_time desc")

   selectOne(selectSql?: string): Promise<T | null>

   demoSqlInstance.selectOne("id=123")

   selectBySql(selectSql: string): Promise<T[]>

   demoSqlInstance.selectOne("select * from todo where id='123' order by create_time desc")

   executeSql(sql: string): Promise

   demoSqlInstance.executeSql("select * from todo where id='123' order by create_time desc")
