Hello!

I'm using datamart and when I load queries after transforming, in Data preview all data of Text and Date types is displayed as null.

I supposed that this is the feature of Data preview and tried to connect to data in Excel using SQL key, but there also only nulls are showed up.

Number values are displayed correctly.

How can I solve this problem?

Best regards,

Helen

It turned out that the Datamart sorts tables from null by default, so rows with all nulls were displayed first)
