You could also try to create a select query and assign it to conection first and let it open until everything was done. This could avoid to the connection to the pool and unassign it.

How looks the code for the creation of the query?

What is the setting for Connection.ResourceOptions.KeepConnection ?

You could also try to enable ExtendedMetaData for connection.

What are your connection settings?

Do you have in your HTML part something like <img src="cid:FileName"> ?

You are using a Generator and a trigger? I thought you were using "generated by default as identity" for field in create table.

In Firebird 4 something like this could work: UPDATE OR INSERT INTO ESTDTL (EST_ID, ESTDTL_ID, CSC_ID, ESTDTLDSC, CSTPLS, GSTINC, GSTPCT, QTYCLC, QTY, CST, GST, SLE, VAL) OVERRIDING USER VALUE VALUES (:NEW_EST_ID, coalesce(:NEW_ESTDTL_ID, -1), :NEW_CSC_ID, :NEW_ESTDTLDSC, :NEW_CSTPLS, :NEW_GSTINC, :NEW_GSTPCT, :NEW_QTYCLC, :NEW_QTY, :NEW_CST, :NEW_GST, :NEW_SLE, :NEW_VAL) MATCHING (EST_ID, ESTDTL_ID) RETURNING EST_ID, ESTDTL_ID

The images are not visible to me. And what was the solution for your initial issue?

Therefore I have used MATCHING (EST_ID, ESTDTLDSC) (And maybe additional fields), because ID is created by DB after post. But maybe there is another solution using the id field...

Have you also provided values for "providerType", "isFolder", ...? See my JSON above.

I have no experience with Microsoft API, but that looks to me that you do not need to create a sharelink first, instead you can directly enter the file or folder as sourceUrl: { "post": { "body": { "contentType": "text", "content": "I attached a reference to a file on OneDrive." }, "attachments": [{ "@odata.type": "#microsoft.graph.referenceAttachment", "name": "Personal pictures", "sourceUrl": "https://contoso.com/personal/mario_contoso_net/Documents/Pics", "providerType": "oneDriveConsumer", "permission": "Edit", "isFolder": "True" } ] } }

And this was my fault: You had a "b.*", not an "a.*".

The modify SQL should look something like this: UPDATE OR INSERT INTO ESTDTL (EST_ID, CSC_ID, ESTDTLDSC, CSTPLS, GSTINC, GSTPCT, QTYCLC, QTY, CST, GST, SLE, VAL) VALUES (:NEW_EST_ID, :NEW_CSC_ID, :NEW_ESTDTLDSC, :NEW_CSTPLS, :NEW_GSTINC, :NEW_GSTPCT, :NEW_QTYCLC, :NEW_QTY, :NEW_CST, :NEW_GST, :NEW_SLE, :NEW_VAL) MATCHING (EST_ID, ESTDTLDSC) RETURNING ESTDTL_ID, ESTDTLMNTDTE

The database file is missing...
