MemSQL version 6.7 and later supports prepared statements; however, server-side prepared statements are not supported when using Audit Logging. If Audit Logging is enabled, attempting to run server-side prepared statements will return the error Feature 'Audit logging with binary protocol' is not supported by SingleStore.

If you are using an older version of SingleStore, or using SingleStore with Audit Logging enabled, SingleStore does not support server-side prepared statements. Instead, many client drivers support a configuration option to allow client-side prepared statements. 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 the MySQL Connector/J (JDBC) driver, set useServerPrepStmts=false, which is the default configuration.

• In MariaDB Connector/J, set useServerPrepStmts=false.

• In ODBC, set no_ssps=1.

• In the Go MySQL driver, set interpolateParams=true.

• In PHP PDO, set PDO::ATTR_EMULATE_PREPARES=TRUE.

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.
