◆ BindBlob()

void cyclus::SqlStatement::BindBlob ( int i,
const void * val,
int n )

Binds the templated sql parameter at index i to the value pointed to by val.

n is the length in bytes of the value.

◆ BindDouble()

void cyclus::SqlStatement::BindDouble ( int i,
double val )

Binds the templated sql parameter at index i to val.

Definition at line 56 of file sqlite_db.cc.

◆ BindInt()

void cyclus::SqlStatement::BindInt ( int i,
int val )

Binds the templated sql parameter at index i to val.

Definition at line 52 of file sqlite_db.cc.

◆ BindText()

void cyclus::SqlStatement::BindText ( int i,
const char * val )

Binds the templated sql parameter at index i to val.

Definition at line 60 of file sqlite_db.cc.

◆ Exec()

void cyclus::SqlStatement::Exec ( )

Executes the prepared statement.

Definition at line 16 of file sqlite_db.cc.

◆ GetDouble()

double cyclus::SqlStatement::GetDouble ( int col)

Returns a double value for the specified column of the current query row.

Definition at line 39 of file sqlite_db.cc.

◆ GetInt()

int cyclus::SqlStatement::GetInt ( int col)

Returns an int value for the specified column of the current query row.

Definition at line 35 of file sqlite_db.cc.

◆ GetText()

char * cyclus::SqlStatement::GetText ( int col,
int * n )

Returns a byte array value for the specified column of the current query row.

This can be used for retrieving TEXT and BLOB column data.

Definition at line 43 of file sqlite_db.cc.

◆ Reset()

void cyclus::SqlStatement::Reset ( )

Executes the prepared statement.

Definition at line 21 of file sqlite_db.cc.

◆ Step()
