Even if you don’t have any values to create a NumPy array, you can still create an array that is empty. Actually, an empty array isn’t empty, it just contains very small, meaningless values. Usenumpy.empty()function to create an empty NumPy array, pass it a shape tuple. The code...
In practice, the effective limit is lower because of tuple-length constraints. The optional constraint clauses specify constraints or tests that new or updated rows must satisfy for an INSERT or UPDATE operation to succeed. A constraint is an SQL object that helps define the set of valid ...
