Using Prepared Statements
Notice
For SingleStore Managed Service, use the endpoint (available in the Portal) to run the commands discussed in this topic.
If you are using an older version of SingleStore DB, or using SingleStore DB with Audit Logging enabled, server-side prepared statements are not supported. 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 just 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 https://dev.mysql.com/doc/connector-j/5.1/en/connector-j-reference-configuration-properties.html.In MariaDB Connector/J, set
useServerPrepStmts=falsehttps://mariadb.com/kb/en/about-mariadb-connector-j/.In ODBC, set
no_ssps=1https://dev.mysql.com/doc/connector-odbc/en/connector-odbc-configuration-connection-parameters.html.In the Go MySQL driver, set
interpolateParams=truehttps://github.com/go-sql-driver/mysql#interpolateparams.In PHP PDO, set
PDO::ATTR_EMULATE_PREPARES=TRUEhttps://www.php.net/manual/en/pdo.setattribute.php.
In many other databases, server-side prepared statements provide performance advantages, but SingleStore DB already compiles and caches query plans internally, so SingleStore DB does not need server-side prepared statements to get most of those performance advantages.
