Thank you @v-jingzhang for information.

Sure we will try to connect Vertica,  Using Vertica datasource connection and check if direct M Query paramenter works or not.

Will keep you posted once done this activity from our side.

Hi @Rahul_Mahajan 

It is because the Dynamic M Query Parameter feature is only available to DirectQuery mode queries. It is not available to queries in Import mode or Live Connection mode. However, the ODBC connector only supports Import mode at present, so you are not able to see the Bind to parameter option. 

Reference:

Power BI data sources - Power BI | Microsoft Docs

User editing of DirectQuery query parameters

Dear @v-jingzhang ,

Thank you for information.

We gone through with given documentation, its say that ODBC not supported in direct query mode as mention in your reply. so can we achive this Direct query using vertica data source- Data query/Live connection ?  kindly assist.

Thank you

Hi @Rahul_Mahajan 

Vertica supports DirectQuery connection. But I'm not sure whether it supports Dynamic M Query Paramters.

In Power BI February 2022 Feature Summary blog, it introduces which data sources are supported currently. Here is the link: Dynamic M Query Parameters now supports SQL Server and more data sources 

When Dynamic M Query Parameters was released, the feature supported M-based data sources (such has Azure Data Explorer, Databricks, BigQuery, Snowflake and more) but did not support other sources like SQL Server. This month we’re excited to announce that Dynamic M Query Parameters now supports more DirectQuery data sources:

• T-SQL based data sources: SQL Server, Azure SQL Database, Synapse SQL pools (such as Azure Synapse Analytics), and Synapse SQL OnDemand pools
• Oracle
• Teradata
• Dataflows (enhanced compute engine enabled)
• SAP Hana Relational

It doesn't mention Vertica so I cannot confirm. Can you give it a try and share your finding with the community?

Dear @v-jingzhang ,

Thank you for your help.

We have tried the Dynamic M Query Parameters with Vertica DB and its working fine as expected.
