# CassStatement

### struct CassStatement

A statement object is an executable query. It represents either a regular (adhoc) statement or a prepared statement. It maintains the queries’ parameter values along with query options (consistency level, paging state, etc.)

**Note:** Parameters for regular queries are not supported by the binary protocol version 1. 

### Public Functions

### [CassStatement](#_CPPv413CassStatement) \*cass_statement_new(const char \*query, size_t parameter_count)

Creates a new query statement.

#### SEE ALSO
[cass_statement_free()](#struct_cass_statement_1aa32f29a76e0c2f5d9a381a9af7d3f719)

* **Parameters:**
  * **query** – **[in]** The query is copied into the statement object; the memory pointed to by this parameter can be freed after this call. 
  * **parameter_count** – **[in]** The number of bound parameters. 
* **Returns:**
  Returns a statement that must be freed.

### [CassStatement](#_CPPv413CassStatement) \*cass_statement_new_n(const char \*query, size_t query_length, size_t parameter_count)

Same as [cass_statement_new()](#struct_cass_statement_1a87a8e954fa8e6df9728b9e7e7eed1ee5), but with lengths for string parameters.

#### SEE ALSO
[cass_statement_new()](#struct_cass_statement_1a87a8e954fa8e6df9728b9e7e7eed1ee5)
