Member Function Documentation

bindDouble()

void Statement::bindDouble ( int32_t  pos, double  value  )

inlineoverridevirtual

Bind the designated parameter to the given 64bit floating point number value.

Parameters

pos	The position of the parameter in the query
value	The value to bind

Implements ledger::core::api::DatabaseStatement.

bindFloat()

void Statement::bindFloat ( int32_t  pos, float  value  )

inlineoverridevirtual

Bind the designated parameter to the given 32bit floating point number value.

Parameters

pos	The position of the parameter in the query
value	The value to bind

Implements ledger::core::api::DatabaseStatement.

bindInt()

void Statement::bindInt ( int32_t  pos, int32_t  value  )

inlineoverridevirtual

Bind the designated parameter to the given 32bit integer value.

Parameters

pos	The position of the parameter in the query
value	The value to bind

Implements ledger::core::api::DatabaseStatement.

bindLong()

void Statement::bindLong ( int32_t  pos, int64_t  value  )

inlineoverridevirtual

Bind the designated parameter to the given 64bit integer value.

Parameters

pos	The position of the parameter in the query
value	The value to bind

Implements ledger::core::api::DatabaseStatement.

bindNull()

void Statement::bindNull ( int32_t  pos )

inlineoverridevirtual

Bind the designated parameter to the NULL value in SQL.

Parameters

pos	The position of the parameter in the query
value	The value to bind

Implements ledger::core::api::DatabaseStatement.

bindShort()

void Statement::bindShort ( int32_t  pos, int16_t  value  )

inlineoverridevirtual

Bind the designated parameter to the given 16bit integer value.

Parameters

pos	The position of the parameter in the query
value	The value to bind

Implements ledger::core::api::DatabaseStatement.

bindString()

void Statement::bindString ( int32_t  pos, const std::string &  value  )

inlineoverridevirtual

Bind the designated parameter to the given string.

Parameters

pos	The position of the parameter in the query
value	The value to bind

Implements ledger::core::api::DatabaseStatement.

close()

void Statement::close ( )

inlineoverridevirtual

Close the statement and release all allocated resources. The statement shouldn't be used after this call.

Implements ledger::core::api::DatabaseStatement.

describeColumn()

std::shared_ptr<api::DatabaseColumn> Statement::describeColumn ( int32_t  colNum )

inlineoverridevirtual

Describe the metadata attached to the designated column (e.g. data type, column name...)

Returns

Column metadata descriptor

Implements ledger::core::api::DatabaseStatement.

execute()

std::shared_ptr<api::DatabaseResultSet> Statement::execute ( )

inlineoverridevirtual

Execute the statement with the past bound values.

Returns

The result of the execution of the statement on the database.

Implements ledger::core::api::DatabaseStatement.

getColumnCount()

int32_t Statement::getColumnCount ( )

inlineoverridevirtual

Get the number of column that will be available into the result row (e.g. "SELECT name, age FROM USERS" would return 2).

Returns

The number of the columns available in the result

Implements ledger::core::api::DatabaseStatement.

reset()

void Statement::reset ( )

inlineoverridevirtual

Reset all bindings. This call is used before reusing a statement instance in order to repeat it multiple time.

Implements ledger::core::api::DatabaseStatement.
