If you are using SET syntax in INSERT statement, you should not use parenthesis around it.

-- One way to insert
INSERT INTO table SET col1 = 'val1', col2 = 'val2';

-- other way
INSERT INTO table(col1,col2) VALUES('val1','val2');

Also use native errors provided by the driver to see what’s wrong with your query
