Thankyou, @nilendraFabric, for your response.
Hi DominilMs,
We appreciate your question on the Microsoft Fabric Community Forum.
From what I understand, @Temp TABLE refers to table variables, which are limited to the current batch or block of the script. This means they work only inside a single Script activity if all operations happen within that same script. On the other hand, #Temp TABLE are temporary tables that only exist for the current SQL session.
In Microsoft Fabric Pipelines, every Script activity runs in its own separate session. Because of this, the #Temp table created in one activity or statement is not accessible in the next activity, even if it is inside the same pipeline. This is why you see the error: 'Invalid object name '#temp'.'
To keep data available across different activities or to avoid this problem, please follow the steps below:
- Use permanent tables by creating a normal table in your Lakehouse or Warehouse for temporary data. Permanent tables stay available across sessions, so you will not face the scope problem.
DROP TABLE IF EXISTS dbo.TempStorage;
CREATE TABLE dbo.TempStorage (sCode VARCHAR(30));
INSERT INTO dbo.TempStorage (sCode) VALUES ('1');
SELECT * FROM dbo.TempStorage;
- If you prefer to use temporary structures like @Temp, make sure all related operations (creation, insert, and select) happen inside one script only. This works because @Temp is available only during the execution of one activity.
DECLARE @Temp TABLE (sCode VARCHAR(30));
INSERT INTO @Temp (sCode) VALUES ('1');
SELECT * FROM @Temp;
