{
    name:'database',
    connection:[
        {
            name:'default',//name of connection
            type:'mongodb',//database type: 'mongodb','mysql','sqlserver'

How to use

Save

if object is exist update else insert

global.db.Save('{connectionName}','{table or collection Name}',[{key list}],object,{Function})

example

global.db.Save('default','news',['title'],{title:'hi',createAt:new Date()},(error,data)=>{
    // After run Save
})

Update

global.db.Update('{connectionName}','{table or collection Name}',[{key list}],object,{Function})

example

global.db.Update('default','news',['title'],{title:'hi',createAt:new Date()},(error,data)=>{
    // After run Update
})

Delete

global.db.Delete('{connectionName}','{table or collection Name}',[{key list}],object,{Function})

example

global.db.Delete('default','news',['title'],{title:'hi'},(error,data)=>{
    // After run Delete
})

Search

global.db.Search('{connectionName}','{table or collection Name}',{query},{odata},func)

Suppose we have an object like this

{
    firstName:string
    lastrName:string
    age:number
    score:number
}

If you want to use Odata:Odata Doc

If you want to use "query" :

• select

examples:

select:['firstName','lastrName','age']

select : ['age',{type:'function',name:'sum',field:'score',title:'totalScore'}]
    

• order by

example:

order:[['age','ASC'],['score','DESC']]      

• where

examples:

grater than

where:{age:{$gt:12}}    Mean age>12

grater or equal than

where:{age:{$gte:12}}   Mean age>=12

lower than

where:{age:{$lt:12}}    Mean age<12

lower or equal than

where:{age:{$lte:12}}   Mean age<=12

equal than

where:{age:{$eq:12}}   Mean age==12 
where:{age:12}   Mean age==12 

not equal than

where:{age:{$ne:12}}   Mean age<>12 | age!=12  

or than

where:{$or:[{age:12},{sccore:{$gte:300}}]}   Mean (age==12 or score>=300) 

and than

where:{$and:[{age:12},{sccore:{$gte:300}}]}   Mean (age==12 and score>=300) 

sample of Search

global.db.Search('default','UserPoint',{
                                            where:{$or:[{age:12},{sccore:{$gte:300}}]},
                                            select:['age',{type:'function',name:'sum',field:'score',title:'totalScore'}],
                                            order:[['age','ASC']]
                                       },
                                       {
                                            $top:10,
                                            $skip:12,
                                            $count:true
                                       },(error,data){
                                            //data.value is list of array
                                            var totals=data.value
                                            //if in odata count=true , return count of data without odata $top and $skip
                                            var totalCount=data.count
                                       })
