Bulk create rows using SQL Server data
Bulk inserts rows into a push dataset table using data from SQL Server. Supply DatasetId and WorkspaceId in the connection string.
Standard SQL query example
This is the base query accepted by the connector. To execute it in SQL Server, you have to pass it to the Data Gateway via a Linked Server. See how to accomplish this using the examples below.
INSERT INTO Products
SOURCE(
'MSSQL',
'Data Source=localhost\developer;Initial Catalog=Northwind;Integrated Security=true',
' SELECT T.* FROM ( SELECT TOP 50
ProductName AS [Name]
,C.CategoryName AS Category
,Discontinued AS IsComplete
,GETDATE() AS ManufacturedOn
,CAST(UnitPrice * ReOrderLevel * 100 AS BIGINT) AS Sales
,CAST(UnitPrice AS DECIMAL) AS Price
FROM Northwind.dbo.Products AS P
JOIN Northwind.dbo.Categories C ON P.CategoryId = P.CategoryId
) AS T
CROSS JOIN GENERATE_SERIES(1, 2000)
-- COMMENT: 50 x 2000 = 100 000 rows
'
)
CONNECTION(
Parameters = '[{ Name: "TokenUrl",Value:"https://login.microsoftonline.com/organizations/oauth2/v2.0/token"}
,{ Name: "DatasetId",Value: "6a0e04da-a6e4-4533-abe4-30fcabd0e2a5"},
{ Name: "WorkspaceId",Value: "848353e2-f3b1-4fb4-89d7-44e84b8bdf9f"}]'
)
Using OPENQUERY in SQL Server
SELECT * FROM OPENQUERY([LS_TO_POWER_BI_IN_GATEWAY], 'INSERT INTO Products
SOURCE(
''MSSQL'',
''Data Source=localhost\developer;Initial Catalog=Northwind;Integrated Security=true'',
'' SELECT T.* FROM ( SELECT TOP 50
ProductName AS [Name]
,C.CategoryName AS Category
,Discontinued AS IsComplete
,GETDATE() AS ManufacturedOn
,CAST(UnitPrice * ReOrderLevel * 100 AS BIGINT) AS Sales
,CAST(UnitPrice AS DECIMAL) AS Price
FROM Northwind.dbo.Products AS P
JOIN Northwind.dbo.Categories C ON P.CategoryId = P.CategoryId
) AS T
CROSS JOIN GENERATE_SERIES(1, 2000)
-- COMMENT: 50 x 2000 = 100 000 rows
''
)
CONNECTION(
Parameters = ''[{ Name: "TokenUrl",Value:"https://login.microsoftonline.com/organizations/oauth2/v2.0/token"}
,{ Name: "DatasetId",Value: "6a0e04da-a6e4-4533-abe4-30fcabd0e2a5"},
{ Name: "WorkspaceId",Value: "848353e2-f3b1-4fb4-89d7-44e84b8bdf9f"}]''
)')
Using EXEC in SQL Server (handling larger SQL text)
The major drawback of OPENQUERY is its inability to incorporate variables within SQL statements.
This often leads to the use of cumbersome dynamic SQL (with numerous ticks and escape characters).
Fortunately, starting with SQL 2005 and onwards, you can utilize the EXEC (your_sql) AT [LS_TO_POWER_BI_IN_GATEWAY] syntax.
DECLARE @MyQuery NVARCHAR(MAX) = 'INSERT INTO Products
SOURCE(
''MSSQL'',
''Data Source=localhost\developer;Initial Catalog=Northwind;Integrated Security=true'',
'' SELECT T.* FROM ( SELECT TOP 50
ProductName AS [Name]
,C.CategoryName AS Category
,Discontinued AS IsComplete
,GETDATE() AS ManufacturedOn
,CAST(UnitPrice * ReOrderLevel * 100 AS BIGINT) AS Sales
,CAST(UnitPrice AS DECIMAL) AS Price
FROM Northwind.dbo.Products AS P
JOIN Northwind.dbo.Categories C ON P.CategoryId = P.CategoryId
) AS T
CROSS JOIN GENERATE_SERIES(1, 2000)
-- COMMENT: 50 x 2000 = 100 000 rows
''
)
