Query crashes when changing for an older date

[Foguete]

Hi ! 

I have a problem. 

I am conected by OBDC with a query that seems to work properly as it returns datas. 

However, when I change the date for an older one in my query, Power Query returns the follow message:

- Query when the date allows a return:

- Query when I change the date for an older one, returning above error:

Any idea what could produce this type of error, because I am very lost to be fair.

Kind regards

Hi @Foguete ,

From the error message it seems that this is a data type conversion error. I found three similar threads, please see if they help:

1. Check the field data type first and query within the desired data type:

sql server - Data conversion or data mapping error in SQL

2. join between mismatching data types:

php - Why am I getting "Data conversion or data mapping error. SQLCODE=-802" on a simple DB2 select ...

3. sql - SQL0802 - Data Conversion or Data Mapping Error

Best Regards,

Thank you !

Indeed, the problem was coming from the only division in the SQL Query.

So to solve I added :

WHERE   the_Dividing_Column <> 0
