How to use sqlwrite

Hi,

I am running into some problems with sqlwrite. I am trying to duplicate the example found here (https://www.mathworks.com/help/database/ug/database.odbc.connection.sqlwrite.html#namevaluepairarguments) where I want to add one row of data to an existing table.

However when I use sqlwrite I get the following error message: Error using database.odbc.connection/sqlwrite (line 85) Multiple table entry found for 'database_table'. Must provide 'Catalog' and 'Schema' values.

I have read the documentation but Im still stuck. I dont understand what the problem is nor how to fix it. Thoughts / ideas ?

Thank you,

conn = database('tt', 'username', 'password'); 

productNumber = [13, 14, 15]';
stockNumber = [47082, 51010, 89975]';
supplierNumber = [1012, 1011, 1011]';
unitCost = [17, 19, 20]';
productDescription = {'Pancakes', 'Shawl', 'Snacks'}';

database_table = table( productNumber, stockNumber, supplierNumber, unitCost, productDescription);

data = table(30, 500000, 1000, 25, "Rubik's Cube", ...
    'VariableNames',{'productNumber' 'stockNumber' ...
    'supplierNumber' 'unitCost' 'productDescription'});

sqlwrite(conn, database_table, data);

close(conn);

Hi Blue,

The error in the code is beacuse of the following lines in your code

database_table = table( productNumber, stockNumber, supplierNumber, unitCost, productDescription);
sqlwrite(conn, database_table, data);

"sqlwrite" function expects second argument to be name of the database table.

This line of code creates a MATLAB table.

database_table = table( productNumber, stockNumber, supplierNumber, unitCost, productDescription);

The code works fine by replacing second argument in "sqlwrite" to any database table name such as 'productTable'

sqlwrite(conn,'productTable',data)

Refere to the sqlwrite documentation for more information on input arguments of sqlwrite.
