Hi there! <br />Can someone look at my solution if it might have concurrency issues with Sqlconnection:<br />1. Dbxexpress connection on Unimainmodule <br />2. One Sqldataset and one dataprovider on a separate datamodule. <br />3. Business logic in a separate unit <br />4. On unimainmodule create ; an instance of datamodule and an instance of datamodule are created and freed on unimainmodule destroy. <br />5. On datamodule create, Sqldataset sqlconnection is set to the sqlconnection from unimainmodule and on datamodule destroy, Sqldataset sqlconnection is set to nil<br />6. One Sqldataset and one dataprovider are shared among clientdatasets on datamodule.<br /><br />Can someone look at this scenario and tell me if there will be concurrency problem? <br /><br />Thanks<br/>
