Importing data for specific dates for Azure Analysis Service Database

[dhruvip23]

Hello everyone,

I am trying to import the last 7 years worth of data from a database with an Azure Analysis Service Database connection. It has data from 1900 and kind of large in size and takes up the whole capacity. What DAX query can I use to only pull a certain amount of data and where do I put it? Thanks for your help

Hi @dhruvip23 ,

Try the DAX below. It screens dates from today to seven years ago.

EVALUATE
CALCULATETABLE(
    'YourTableName',
    'YourTableName'[YourDateColumnName] >= DATE(YEAR(TODAY()) - 7, MONTH(TODAY()), DAY(TODAY())) 
    && 'YourTableName'[YourDateColumnName] <= TODAY()
)

Hey Gao,

Thank you so much for this, it works as I expected it to be. Now, the only issue I've got is the table I want to bring in doesn't have any date table. Althogh I've applied the DAX to the other table and it worked out but how do I add that date column into my cuurent table. Many thanks.

Hi @dhruvip23 ,

What about passing filters like this? Assuming that the table does not contain dates, consider filtering out the KEY by other containing dates first, and then filtering the table using the KEY.

EVALUATE
VAR __keys =
    CALCULATETABLE (
        VALUES ( 'OtherTablehasDate'[FieldName] ),
        'OtherTablehasDate'[Date]
            >= DATE ( YEAR ( TODAY () ) - 7, MONTH ( TODAY () ), DAY ( TODAY () ) )
            && 'OtherTablehasDate'[Date] <= TODAY ()
    )
VAR __result = CALCULATETABLE('Table',TREATAS(__keys,'Table'[FieldName]))
RETURN
    __result

Hi @dhruvip23  - These are my finding, comments and questions related your post.

1. First of all, we need to understand which AAS tier is being used here. Please refer below link for the size and pricing. https://azure.microsoft.com/en-us/pricing/details/analysis-services/

2. If data size is more the the AAS tier that being used, we will face the memory issue. So we should revisit if AAS tier is enough or need to upgrade the tier

3. We can still optimise the data model to fit into the existing tier but to understand that we need to look into the model or share below information if possible.

• No of Tables used and respective relationship 
• Help us to identify which are dimension tables and which one is fact
• No of Columns and Rows in the each column based on Data Type

Based on the information, we can help more to resolve this issue or provide better way to fix this issue
