Systems and methods for cancelling a query

A server computing device for querying a database, comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the server computing device to:
• receive a query input from a client device over a network connection;
• establish a non-blocking socket between the client computing device and the server computing device;
• generate a database query based on the query input;
• cause the database query to begin executing against one or more databases;
• perform a read request on the non-blocking socket;
• receive a code in response to the read request on the non-blocking socket;
• determine whether the network connection exists between the client device and the server device based on the received code;
• and
• cause the database query to be cancelled when the server determines that the network connection does not exist between the client device and the server device.

A client computing device for querying a database, comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the client computing device to:
• transmit a query input to a server computing device over a network connection, wherein a non-blocking socket is established between the client computing device and the server computing device, and wherein a database query is generated and executed against one or more database based on the query input;
• receive a read request from the server computing device on the non-blocking socket;
• and
• transmit a code to the server computing device in response to the read request on the non-blocking socket, wherein the code allows the server computing device to determine whether the network connection still exists between the client device and the server computing device based on the received code, and wherein the server computing device is able to cause the database query to be cancelled when the server computing device determines that the network connection does not exist between the client device and the server computing device.
