Hi Mike,

Thanks for putting this together! I'd like to have the sheet I'm using this on overwrite the tab's contents whenever this script is executed. I thought I could add clearSheet to line 94 would do it, but that just returns 'clearSheet is not defined'. Sorry for bugging you - I'm sure this is a basic question.

@remanifest you just need to add an options object to runSql with {clearSheet: true}

how do I actually run this and pass a query?
Do I make a button and assign the script and hardcode the sql there? I'm not sure how it fits together

do I need a supplemental file?

Exception: No HTML file named sidebar was found.

Are there docs for this project somewhere?

@Maxhodges here's the post that goes thru it

Thanks for this!
I am facing an issue when I connect to MySQL 8 (https://issuetracker.google.com/issues/119660771)
Anybody found a workaround?

@alan345 I don't think Google's JDBC support MySQL 8 yet.

Shameless plug: You can try https://seekwell.io/

I have data within my organisation Intranet. I want to bring data on our mobile through Microsoft Power Apps so that we can see parameters from our mobile phones.

I have saved all parameters in excel on my office desktop and it gets continuously updated also.

Now I want all those data in google sheet and want google sheet to update per sec as per the excel sheet on my desktop.

pls guide how to use your code.

Thanks

Hey just a suggestion - don't publish database credentials, it's a bad idea :)

@XxLilBoPeepsxX it's on purpose. It's a demo database with a demo user specifically for this purpose.

How do I configure this to use with Microsoft SQL server and on a different server? Is there a way to automate it, so it pulls automatically when the sheet is loaded? Thanks.

@spra8560 Do you know your credentials? i.e. the hostname, username, password for SQL Server?

You could add an apps script trigger to run the script when the Sheet is open. We also offer scheduling (without writing code to do it) thru https://seekwell.io/

Good Morning Mr. Mike, Yes, I know the credentials and observed in the post where it says to use SQL server as the type.  I work for GSA (Federal Agency) and attempting to use Google Sheets to provide real time meter status for our buildings and trending data (up to a year) for all 100+ buildings in our region.   Our IT department has turned off ODBC but I can push data from Niagara (BAS Software) to SQL server via JDBC or MSSQL connector.   In the database I have configured I have 300+ tables (3-4 meters per site).   I don't mind requesting a purchase of the software/script you have, I just have to get it past the sniff test of the IT dept and has to work with what restrictions are in place.  I utilized the script you had but not sure how to set it up for each table (if I need to setup a tab for each, etc).   Please advise at your convenience.  Thanks.

@spra8560 Hey Ramon - Could you send me a note at mike@seekwell.io? Happy to help you get set up with this.

Hi @mike-seekwell
Thanks for really helpful scripts.
In my case, I want to retrieve only 1 certain table in database. How should I edit the code?
Thanks again Mike.

Hi, Thanks for the script - We secure our db by whitelisting ips - do you know where I can find which ips to whitelist to make this work?
