SQL errro when importing entities from MySQL in integration studio


In Outsystem integration studio, I am creating a .Net extension and trying to import table (entities) from external MySQL database. In case of some entities its showing error and unable to publish the entity.

Below are the error which am facing :

An error occurred while publishing the Extension: System.Data.SqlClient.SqlException (0x80131904): String or binary data would be truncated.
The statement has been terminated.

Kindly suggest, what may be reason of error. I have checked by changing different data types in database. 

I have found the root cause of issue. Actually in MySQL database, Enum are string type like value is "startup", "sme" etc. When we limited this value to one character only like "s", "m". It works fine. Now my problem is how to import this kind of Enum in extension. Please suggest.

Thank you,

Hi Vikas,

The error message you get, "String or binary data would be truncated", means that you try to store a text (or binary) in the database that is larger than the maximum reserved space for it. It seems there is a table that you try to put one of the "enums" in them (in OutSystems, these would be "Static Entities"), but there's less space than the length of the texts.
