make a function to getdata from different databases

[Anonymous]

Hi,

i have an SQL database with several "customer" tables over different databases. Of course i can load them seperately and with append-queryies merge them in a new table.

Now i want to be more flexible because i have over the 15 databases.

The different names of the databases can i save in new table (in my example 001, 002, 003 etc) . After that i want to invoke a funtion that for each database load the "customer" table and merge it in a new table.

let
    Source = Sql.Databases("Server"),
    #"001" = Source{[Name="001"]}[Data],
    customer1 = #"001"{[Schema="dbo",Item="customer"]}[Data],
in
    customer1
- - - - - - - - - - - - -
let
    Source = Sql.Databases("Server"),
    #"002" = Source{[Name="002"]}[Data],
    customer2 = #"002"{[Schema="dbo",Item="customer"]}[Data],
in
    customer2

Can someone help me make this function and how to implementate this?

With kind regards

Hello @Anonymous 

Create your own function that uses the table as parameter.

I will not be able to post here the complete function, but I will put down an example how to achieve this

function could look like:

(customertable) =>
let
    Source = Sql.Databases("Server"),
    #"001" = Source{[Name=customertable]}[Data],
    customer = #"001"{[Schema="dbo",Item="customer"]}[Data],
in
    customer

then create a table and add new column to invoke the function (code is not tested)

let
    Table = #table({"Customer""}, {{"001"},{"002"},{"003"}},
    AddColumn = Table.AddColumn(Table,"SQL",each YourFunctionName([Customer]))
in
    AddColumn

this was the solution:

(Databasenaam, Tabelnaam) =>
let
    Bron = Sql.Databases(Server),
    Database = Bron{[Name=Databasenaam]}[Data],
    Tabel = Database{[Schema="dbo", Item=Tabelnaam]}[Data]
in
    Tabel

let
    Table = Databases,
    Records = Table.AddColumn(Table, "Records", each HaalTabelOpUitDB([Databasenaam], "bedryf"))
in
    Records

Hi @Anonymous 

The below syntax will list all the database, then you will be able to reference this as a connection and expand all the tables you need and append together.

let
    Source = Sql.Databases("Server") 
in
    Source
