#include <preparedstatement.h>
A prepared statement is precompiled by the driver and/or datasource, and can be executed multiple times with different parameters.
Parameters are set using the setXXX methods. Note that it's advisable to use the set method compatible with the parameter's SQL type - for example, for a Types::DATE
, setDate()
should be used. Question marks ("?"
) are used in the SQL statement to represent a parameter, for example:
std::auto_ptr<PreparedStatement> pstmt =stdauto_ptr<PreparedStatement>(con->prepareStatement ("INSERT INTO SOMETABLE(AN_INTEGER_COL,A_VARCHAR_COL) VALUES(?,?)")); pstmt->setInt(1,10); pstmt->setString(2,"Hello, world!"); int affectedRows=pstmt->executeUpdate();
void odbc::PreparedStatement::clearParameters | ( | ) |
Clears the parameters.
The set of parameters stays around until they are set again. To explicitly clear them (and thus release buffers held by the driver), this method should be called.
bool odbc::PreparedStatement::execute | ( | ) |
Executes this statement.
