I've been used to quickly uploading a CSV file to append data to an existing table in BigQuery.
I've made the new table name the same as the existing table, and I've then had options to overwrite or append data to the existing table.
This seems to have changed in the past few days and there is a new BigQuery console UI.
When I try and create a new table from a CSV file upload, under the table name field it currently says:
Unicode letters, marks, numbers, connectors, dashes or spaces allowed.
The job will create the specified destination table if needed, or the
table must be empty if it already exists.
However, when I try and create a table with the same name as an existing table (even though the existing table is empty), I get a red warning saying:
Table already exists
Does anyone know if this feature has now been removed or how to easily append data?
The long way round is to upload a CSV to a new table, then query the new table and set the destination to append or overwrite an existing table. Not ideal, particulalry having to define a new table schema.
In order to append a CSV file to an existing BigQuery table when using the Console, please follow the instructions below:
In the Explorer panel, expand your project and select a dataset.
Expand the Actions option and click Open.
In the details panel, click Create table.
On the Create table page, in the Source section:
For Create table from, select Upload.
Browse file from system
On the Create table page, in the Destination section:
For Dataset name, choose the appropriate dataset.
In the Schema section, for Auto detect, check Schema and input parameters to enable schema auto detection. Alternatively, you can manually enter the schema definition
Click Advanced options.
For Write preference, choose Append to table

I created a new datasource with 4 tables of a sql database. In my first form i created a to_table_1 _bounded gridview via drag and drop. This created table Adapter and table adapter manager for example, which a bound to the form. Now I have a module1 where I want to perform an Insert Statement from the Table2Tableadapter. But I dont know how i can talk to the adapter, if I not create a gridview anywhere. I want to talk to the Datset.xsd table2 Adapter. Ther I already set up the sql Statements and the Insert statement is nevertheless Standard implemented in the adapter.
I know this must be so easy for someone who worked more then one time with databases. Hope You can help!
Cheers Steven
If you want to do your data access in a module then don't create the table adapter in the form; create it in the module. The Data Source wizard generates classes and you use those classes the same way you would any other. Do you have a problem using a String in a module? Of course not., If you want a String then you create a String. The same goes for a table adapter.
When you drag items onto a form from the Data Sources window it will generate some items automatically. There's no requirement that you keep all those items. Just delete the table adapter and manager and any code that uses them, then write your own code to populate a DataTable in your module. You've still got the DataSet in the form so you simply pass that, or a specific DataTable it contains, to your module to populate it.
You could go further and remove the DataSet from the form too and then use the GetData method of your table adapter to create a new DataTable and return that to the form. It's up to you. Don't limit yourself by what's generated for you. That is there to help but it's not the only way to do things. If you want to create something then create it.

I am using a combobox in VB .net to show customer's name. They also can type new names if they wish. Can I somehow save these new names in my sql database dynamically?
What I mean is if the name is new and does not exist in my database, can it be automatically saved to the database?
My combobox is bound to my name table.
Thanks.
If your combobox is bound to a datatable, then you should be able to use a DataAdapter to update the database table based on your datatable.
You could possibly also make this automatic by tying it into the combobox Validated event.
