Error OLE DB u ODBC

aishak12 what is your data source? SQL Server? Seems like it is not available to connect. Try to connect using SSMS to see if you can connect to SQL Server if that is your source.

aishak12 , With this error, Seems like there is column with data type int and it now getting some text value, now. Open Edit Query/ data Tranformation mode, and check for error. Either a message on top of tables display or in columns.  Find the column with issue and correct it

Please refer these for debugging

Hi aishak12 

The error is telling you that a VARCHAR is being coverted to INT.  Your query is returngin VARCHAR data in a column and then trying to convert that to INT.

Find the column where ths problem is happening by checking your query code.
