You can get your database connection details from whoever set up the database. You'll also need to get them to whitelist the Retool IP address.
Create a new resource in Retool, and select "Microsoft SQL" as the type.
Enter your database connection details.
You can now select your newly-created SQL Server resource from the Resource dropdown when creating queries in your Retool apps. You can toggle between SQL mode for raw SQL statements or the GUI mode for structured writes.
You can display the results of SQL Server queries as with any other query in Retool:
Images in MSSQL are stored as a
varbinary. To display them in Retool, you'll need to convert them to Base64 first. Here's an example of a stored procedure from one of our community members that can do the trick:
CREATE PROCEDURE [dbo].[spImageData_Put] ( – @Base64String as varchar(MAX), @TableID as integer ) AS BEGIN SET NOCOUNT ON update [dbo].[testtable] set base64imagestring = @Base64String, imagefield = CAST(N’’ AS xml).value(‘xs:base64Binary(sql:variable("@Base64String"))’, ‘varbinary(max)’) where TestTableID = @TableID END GO CREATE function [dbo].[fnConvertBinaryToBase64] (@BinaryImage varbinary(max)) RETURNS varchar(MAX) AS BEGIN DECLARE @result varchar(MAX) set @result = cast('' as xml).value('xs:base64Binary(sql:variable("@BinaryImage"))', 'varchar(max)') RETURN @result; END GO
