mysqlstmtinit

mysqlstmtinit is a function within the MySQL C API that initializes a prepared statement object. It takes a MySQL connection handle and a SQL query string as arguments and returns a MYSQL_STMT structure. This structure represents the prepared statement and is used for subsequent operations like binding parameters, executing the statement, and fetching results. The function prepares the SQL query for efficient execution by parsing, compiling, and optimizing it on the database server. This preparation step is performed only once, and the compiled statement can then be executed multiple times with different parameter values, which can significantly improve performance for repetitive queries. If the preparation is successful, mysqlstmtinit returns a pointer to the MYSQL_STMT structure. If an error occurs during preparation, it returns NULL, and the error can be retrieved using mysql_stmt_error. Proper initialization of a prepared statement is crucial before performing any other statement-related operations.
