Use a PostgreSQL native interface database connection to insert product data from MATLAB® into a new table in a PostgreSQL database. Then, reverse the changes made to the database.

Create a PostgreSQL native interface database connection to a PostgreSQL database using the data source name, user name, and password. The database contains the tables productTable and suppliers.

datasource = "PostgreSQLDataSource";
username = "dbdev";
password = "matlab";
conn = postgresql(datasource,username,password);

Allow manual committing of changes to the database by setting the AutoCommit property to off.

conn.AutoCommit = "off";

Create a MATLAB table that contains data for two products. The data is stored in the productTable and suppliers tables.

data = table([30;40],[500000;600000],[1000;2000],[25;30], ...
    ["Rubik's Cube";"Doll House"],'VariableNames',["productNumber" ...
    "stockNumber" "supplierNumber" "unitCost" "productDescription"]);

Insert the product data into a new table named toytable.

tablename = "toytable";
sqlwrite(conn,tablename,data)

Import the contents of the database table into MATLAB and display the rows. The results contain two rows for the inserted products.

rows = sqlread(conn,tablename)

rows=2×5 table
    productnumber    stocknumber    suppliernumber    unitcost    productdescription
    _____________    ___________    ______________    ________    __________________

         30             5e+05            1000            25         "Rubik's Cube"  
         40             6e+05            2000            30         "Doll House"    

Reverse the changes made to the database.

rollback(conn)

Search for the table. The table no longer exists.

data = sqlfind(conn,tablename)

data =

  0×5 empty table

Close the database connection.

close(conn)
