I am querying a large public data set in Big Query and when I select the entire table, I get an error saying the result is too big and I should enable the "Allow Large Results". I read through the documentation for this and followed the steps mentioned,
Select a destination table
Check " Allow Large results"
Despite doing this I get a very vague error that says "Required parameter Missing". I am not sure how to fix this error and what parameter is missing. I Wuld greatly appreciate if anyone who has encountered this error is able to provide some inputs
Error page snapshot
Check out value for your destination table! - data-analyst-1326:null.tbl1
The dataset value is null!
Hope this will help

I am doing something that seems like it should be very easy yet I have yet to figure this out. I have read countless posts and tried everything I can think of and still no success.
Here goes:
I created a Pipeline Parameter pplLastWritten with a default value of 2022-08-20 12:19:08 (I have tried without the time for troubleshooting and still get errors)
Then I create a Data Flow Parameter ptblTableName
I have tried to convert to a Date, keeping as is and converting later...you name it still errors out.
In the expression builder I tried this and many more ways to build out to a sql statement:
"SELECT * FROM xxxxxx."+$ptblTableName+"where Lastwritten>='{$ptblLastWritten}'"
This is the post I got the idea from: ADF data flow concat expression with single quote
This is the error I got most of the time.
Operation on target df_DynamicSelect failed: {"StatusCode":"DF-Executor-StoreIsNotDefined","Message":"Job failed due to reason: at Source 'RptDBTEST'(Line 5/Col 0): The store configuration is not defined. This error is potentially caused by invalid parameter assignment in the pipeline.","Details":""}
I have tried so many things but in the end nothing has worked. I am new to Data Factory and come from the SSIS world which was so much easier. I would greatly appreciate someone helping. Please explain this like I'm a kindergartener because this tool is making me feel like it. :) Thank you in advanced.
I have tried various ways to format
Using different ideas in the expression builder
the ideas in this post: ADF data flow concat expression with single quote
You can use concat() function in the Data flow dynamic expression like below.
Here is the sample data in SQL.
I have created two dataflow parameters mytable and mydate.
Passed the values like below. Check the expression checkbox. For date you can also pass like this '2022-11-07T00:00:00.0000000'.
In the Query option use below Expression.
concat('select * from dbo.',$table_name,' where mydate >=','\'',$mydate,'\'')
Values inserted in Target table.
sq
in image you can see that i am getting error "invalid number".
how can i fix this error.
you should check your data types for every column where you want to insert data. For example I see that you try to add data with "$9,99" which seems a little bit strange. May have a look again.
Maybe there is a column of orders which expects a number and you're trying to insert an non-number.
You could double-check the table definition in SQL Developer or by using DESC <table>.
When creating a BigQuery data connector for Google Data Studio, my query works until I attempt to parameterize some fields. As soon as I add parameters, I get the unhelpful and unspecific error:
The query returned an error.
Error ID: xyz
How can I figure out what the underlying issue is that is causing this problem?
1. Check BigQuery Logs in Cloud Logging
If there is an error executing a query in BigQuery, the underlying cause will likely be visible in Cloud Logging. In Cloud Logging, execute this query to show these errors, and hopefully get insight into the underlying problem:
resource.type="bigquery_resource"
severity=ERROR
Its possible these logs will show that the query is failing because the format of certain data is invalid -- in that case its likely because having no default values for parameters is preventing the BigQuery query from succeeding. In that case:
2. Give Parameters Default Values
The connector passes the query to BigQuery, which executes it. In order for this to work correctly, the parameters need to have some values. Provide them in the form of parameter default values that will result in a valid query.
I have a valid SQL query in Big Query which executes fine when run. However, Big Query tells me 'an internal error occurred and the request could not be completed' under the validator and as such I cannot save the query as a view.
Why is this? It's very frustrating and it hasn't happened with other queries I've written. I've double checked all the schema references are fully defined etc. It's been happening for the past 3 days now.
Many thanks for any help.
I'm tasked to create a program that will run an extremely long query. That query executes well in Oracle but whenever I try to run it from VB.Net, it results to the error mentioned on the title. And also, I have noticed that when I copy my query to an SQLDataSource, it copied only certain parts and not the whole query. Is there any chance for this? Thank you!
