SQL Tips: Insert Value using Identity from Previous Insert

Ever find yourself needing to write SQL code to run on multiple tables where one of the values in a secondary INSERT statement is dependent upon the identity value from previous insert? Well, if so, this should work for you…

[code language=”sql”]DECLARE @NewApiId int;
INSERT INTO APIs (Name, Description) VALUES (‘Social Links’,’The Social Links API, available only to corporate clients, will output a report all of the clients for the client”s ClientTypeID that includes all of the recorded social media properties’);
SELECT @NewApiId = CAST(scope_identity() AS int);
INSERT INTO ApiSubscriptions (ApiId, ClientId) VALUES (@NewApiId, 666);
select * from APIs;
Select * from APISubscriptions WHERE ClientId=666;[/code]

Pretty simple, no?

I'm a technologist at heart, assisting companies best utilize the Internet to market themselves and sell their products and services online. This includes organizations as large as Google and as small as one or two individuals.
At Over The Top and Exhibit A Communications, I've programmed solutions for Google as well as at least one other company that was later acquired by Google.

I've been CTO of an Internet SaaS company and spent my time pretty evenly between guiding the future technical strategy of the company, architecting software solutions for my dev teams, designing and running a data center to service our clients world-wide as well as being a technical evangalist/sales engineer to our media clients large and small.

I've also been Chief Photographer of the Daily Sun/Post newspaper back when it was a 5-day a week daily newspaper.

I also spent a great many years as a beach lifeguardfor the City of San Clemente as well as Jr. Lifeguard instructor and then as it's program coordinator.
