I'm connected to MySQL DB.
A week ago I installed the new personal gateway and all refreshes ran smoothly.
Starting yesterday, I've been getting the following error:
"There was an error when processing the data in the dataset".
---> "Value was either too large or too small for an int64.. The exception was raised by IDataReader interface. Table: xxx"
One important thing to note is that some of the refreshes are OK, but some fail.
Why is that ?
How can I fix it ?
