This configuration option may also be referred to as client-side prepared statement emulation or parameter interpolation. You can use the same code in your application, but change a flag in the client driver configuration. For example:

In many other databases, server-side prepared statements provide performance advantages, but SingleStore already compiles and caches query plans internally, so SingleStore does not need server-side prepared statements to get most of those performance advantages.
