I'm working on Sql server to Snowflake migration project,So i pointed ssrs reports to Snowflake data source and converting sql queries as per snowflake,but i'm not able to get how can we write queries for parameterized reports.Example select * from Student where Std_id=#id,want to convert to snowflake query.
You can use SQL variables:
https://docs.snowflake.com/en/sql-reference/session-variables.html
or Snowflake Scripting Variables:
https://docs.snowflake.com/en/developer-guide/snowflake-scripting/variables.html
I think the SQL variables would be helpful in your case, but Snowflake Scripting variables would be more similar to your SQL Server # variables.

I am using SQL Server 2008 and want to convert table data into json format. Can I convert it directly through firing query?
I have created a stored procedure that can take your table and output JSON. You can find it at
GitHub - SQLTableOrViewToJSON
Once you run the stored procedure, you can output your table by making a call like the following:
EXEC SQLTableOrViewToJSON 'MyTable', 'C:\WhereIStowMyJSON\'
Built in support for formatting query results is added in SQL Server 2016 and it will be available in Azure Database.
In older versions you would need to use CLR or some heavy TSQL like:
Producing JSON Documents from SQL Server queries via TSQL
The above solutions seem unnecessarily complicated; starting with 2008, SQL Server supports the following syntax (answer from DBA StackExchange)
SELECT * FROM dbo.x FOR JSON AUTO;
The above query returns a single JSON-formatted column that looks like this (assuming dbo.x contains columns col1~col4of corresponding types):
[{"col1":"val1","col2":"val2","col3":5,"col4":"2019-02-11"}]

SO heres what I am trying to do.
I have a table which has 2 columns - QC_Check and Query. For each QC_Check I have a query. There are several records like this.
Is there a way using SQL transformation that, I can fetch the SQL query stored in the Query column to Informatica, run the queries in Teradata and get the results stored somewhere.
Although, I have not tried it myself, this should be possible using SQL transformation in Query mode with Dynamic SQL Queries.
Use the table with Query column as a source. Create a SQL transformation with Query mode. Connect the Query column to the SQL transformation.
Write ~Query_Port~ in the SQL editor in the SQL transformation:
If you want to capture the results from your query, you have to configure output ports for columns you retrieve from the database.
I've written an oracle query which executes fine against Oracle 11g DB (I wrote it in PL/SQL developer). But when I try to copy/paste it into Microsoft Query as SQL, it fails with ORA-00900: invalid SQL statement.
Is there a list of what can be included in query for Microsoft Query to be treated as valid? In my query I use a lot of SQL modelling - is it not supported?
I don't believe any of the MODEL features of Oracle are supported by any MS SQL variant.
But as that is an ORA message you are still executing against Oracle, I have to assume that the connection is messing with the SQL. Why do you need to issue the sql through MS Query?
(Perhaps you could define a view/function/proc in Oracle with your model syntax, and then use that object through MS Query)
What is a dynamic SQL query, and when would I want to use one? I'm using SQL Server 2005.
Here's a few articles:
Introduction to Dynamic SQL
Dynamic SQL Beginner's Guide
From Introduction to Dynamic SQL:
Dynamic SQL is a term used to mean SQL code that is generated programatically (in part or fully) by your program before it is executed. As a result it is a very flexible and powerful tool. You can use dynamic SQL to accomplish tasks such as adding where clauses to a search based on what fields are filled out on a form or to create tables with varying names.
Dynamic SQL is SQL generated by the calling program. This can be through an ORM tool, or ad-hoc by concatenating strings. Non-dynamic SQL would be something like a stored procedure, where the SQL to be executed is predefined. Not all DBA's will let you run dynamic SQL against their database due to security concerns.
A dynamic SQL query is one that is built as the program is running as opposed to a query that is already (hard-) coded at compile time.
The program in question might be running either on the client or application server (debatable if you'd still call it 'dynamic') or within the database server.
