PowerBI Data Types
Hello,
I'm importing data from a mySQL database to run some reports on. There is a column that repsents the coupon type and is identified by a number 1 - 5.
When the data is loaded into PowerBI, it categorizes this column as a Boolean, specifically True, vs. the whole number it actually is.
When I query the Database outside of PowerBI I can see each of the whol enumbers appropriately (1 -5).
Is there a way I can load this datatype specifically before PowerBI Transforms it automatically for me?
The column causing trouble was type TINYINT inside the database. I created a new datasource and wrote a SQL statement that used the CAST() function to change the type and load it into PowerBI successfully.
For reference, it looked like this:
CAST(coupon.type AS SIGNED) as coupon_Type

When you look at the data in Power Query, you should be able to edit or delete the step that wrongly identifies the column as a bool.
It happens upon initial data load, so it seems there is no step to delete or change. I've tried changing it post load but the BOOL becomes a 1 or 0 when I change it to a whole number type.
Hi JacktheYeti ,
Method 1:
Go to File->Options and settings-> Options, disable the type detection option like picture below (disable the option will affect all fields' type detection, so do this carefully).
Method 2:
Change the data type in Report view or Data view .
Method 3:
Enter into Query Editor, delete the step named "Changed Type", or change the data type.
Best Regards,
Amy

Thanks Amy, I gave this a try but was unsuccessful. The data would load in as TRUE and FALSE or 1 and 0.
