Constructor & Destructor Documentation

CQuery() [1/3]

CQuery::CQuery

(

void

)

Empty constructor of query object.

Object created this way cannot be used for anything except assigning from the other query object.

Definition at line 3884 of file sdbapi.cpp.

~CQuery()

CQuery::~CQuery

(

void

)

Definition at line 3896 of file sdbapi.cpp.

CQuery() [2/3]

CQuery::CQuery

(

const CQuery &

q

)

Copying of query object from other one.

The copy of query object behaves with the same internal result set as the original object. So that if you increment iterator created from one object it will move to the next row in another query object too.

Definition at line 3892 of file sdbapi.cpp.

CQuery() [3/3]

CQuery::CQuery ( CDatabaseImpl *  db_impl )

private

Create query object for given database object.

Definition at line 3887 of file sdbapi.cpp.

References m_Impl, and CRef< C, Locker >::Reset().

Member Function Documentation

begin()

CQuery::CRowIterator CQuery::begin

(

void

)

const

Start iterating through next result set.

If a query was supplied but not explicitly executed, automatically execute it before proceeding. If iteration was already in progress, purge the remainder of the current result set and advance to the next, if there is one.

Definition at line 4186 of file sdbapi.cpp.

References CQueryImpl::BeginNewRS(), CRef< C, Locker >::GetNCPointer(), and m_Impl.

Cancel()

void CQuery::Cancel

(

void

)

Cancel the current statement or procedure call.

May be called asynchronously to force a "timeout" within one second.

Definition at line 4057 of file sdbapi.cpp.

References CQueryImpl::Cancel(), and m_Impl.

ClearParameter()

CQuery & CQuery::ClearParameter

(

CTempString

name

)

Remove parameter with given name from parameter list.

Definition at line 4022 of file sdbapi.cpp.

References CQueryImpl::ClearParameter(), and m_Impl.

end()

CQuery::CRowIterator CQuery::end

(

void

)

const

Get iterator pointing to the end of the current result set or to the end of all result sets (depending on the setting changed with SingleSet() and MultiSet()).

Method cannot be used to take two different iterators - one for the end of result set and one for the end of all result sets. Which end is pointed to depends on the last call to SingleSet() or MultiSet() even if it was made after call to this method.

Execute()

CQuery & CQuery::Execute

(

const CTimeout &

timeout = CTimeout(CTimeout::eDefault)

)

Explicitly execute sql statement.

All result sets left from previous statement or stored procedure execution are purged. The query reverts to SingleSet mode, with no row count requirements.

Definition at line 4043 of file sdbapi.cpp.

References CQueryImpl::Execute(), and m_Impl.

ExecuteSP()

CQuery & CQuery::ExecuteSP	(	CTempString	sp,
		const CTimeout &	timeout = CTimeout(CTimeout::eDefault)
	)

Execute stored procedure with given name.

All result sets left from previous statement or stored procedure execution are purged. The query reverts to SingleSet mode, with no row count requirements.

Definition at line 4050 of file sdbapi.cpp.

References CQueryImpl::ExecuteSP(), and m_Impl.

GetColumnName()

string CQuery::GetColumnName

(

unsigned int

col

)

const

Get name of the column with given number in the current result set.

All columns are numbered starting with 1.

Definition at line 4174 of file sdbapi.cpp.

References CQueryImpl::GetColumnName(), and m_Impl.

GetColumnType()

ESDB_Type CQuery::GetColumnType

References CQueryImpl::GetColumnType(), and m_Impl.

GetParameter()

const CQuery::CField & CQuery::GetParameter

(

CTempString

name

)

Get value of the parameter.

For eSP_In parameter value set to it will always be returned. For eSP_InOut parameter value set to it will be returned before stored procedure execution and value returned from procedure after executing it and reading its row results (or confirming that it produced none). Throw an exception if no such parameter exists, or if it's an output parameter but not yet available because the caller hasn't finished processing results.

Definition at line 4016 of file sdbapi.cpp.

References CQueryImpl::GetParameter(), and m_Impl.

GetPrintOutput()

const list< string > & CQuery::GetPrintOutput

(

void

)

const

Get any PRINT output from the latest procedure call (or statement).

This output may be incomplete until the caller has explicitly read or purged all result sets.

Note

Many actions can invalidate this output, even working with other CQuery objects associated with the same CDatabase object or a normal (non-clone) copy thereof.

Definition at line 4132 of file sdbapi.cpp.

References CQueryImpl::GetPrintOutput(), and m_Impl.

GetResultSetNo()

unsigned int CQuery::GetResultSetNo

(

void

)

const

Get number of currently active result set.

All result sets are numbered starting with 1.

References CQueryImpl::GetResultSetNo(), and m_Impl.

GetRowCount()

int CQuery::GetRowCount

(

void

)

const

Get number of rows read after statement execution.

This number is available only when all result sets are read or purged by call to PurgeResults(). At all other times, the method throws an exception.

Definition at line 4120 of file sdbapi.cpp.

References CQueryImpl::GetRowCount(), and m_Impl.

GetRowNo()

unsigned int CQuery::GetRowNo

(

EHowMuch

how_much = eAllResultSets

)

const

Get row number currently active.

Row numbers are assigned consecutively to each row in all result sets returned starting with 1. With eAllResultSets (default) or in MultiSet mode, row number is not reset after passing result set boundary.

Definition at line 4114 of file sdbapi.cpp.

References CQueryImpl::GetRowNo(), and m_Impl.

GetStatus()

int CQuery::GetStatus

(

void

)

const

Get return status of stored procedure.

Status is available only if stored procedure is executed via ExecuteSP() method and all result sets returned from the procedure are read or purged by call to PurgeResults().

Definition at line 4126 of file sdbapi.cpp.

References CQueryImpl::GetStatus(), and m_Impl.

GetTheOnlyRow()

CQuery::CRow CQuery::GetTheOnlyRow

(

void

)

Provides the only row for the executed query.

It makes sure that there is exactly one row available and that the required row count range includes 1. VerifyDone() is called in the method so the user does not need to call it. In case of any problems a CSDB_Exception exception is generated.

Definition at line 4077 of file sdbapi.cpp.

(

void

)

Check if any more result sets are available for reading.

Advances to the next result set purging all remaining rows in current one if reading of it was already started (begin() method was called).

Definition at line 4138 of file sdbapi.cpp.

References CQueryImpl::HasMoreResultSets(), and m_Impl.

MultiSet()

CQuery & CQuery::MultiSet

(

void

)

Convert this query to not merge different result sets, i.e.

iterator will be equal to end() at the end of each result set and to switch to the next one you'll have to call begin() again. Method impacts not only this CQuery object and all iterators created from it but all copies of this CQuery object too.

RequireRowCount() [1/2]

void CQuery::RequireRowCount	(	unsigned int	min_rows,
		unsigned int	max_rows
	)

Indicate the minimum and maximum number of rows the active query should return.

In MultiSet mode, the requirement applies to individual result sets. (Callers may specify the requirement for each set as it comes up, or let it carry over unchanged.) Any call to this method must follow Execute or ExecuteSP, which reset any such requirements.

Parameters

min_rows	Minimum valid row count.
max_rows	Maximum valid row count. (kMax_Auto for no limit.)

(

unsigned int

n

)

Indicate precisely how many rows the active query should return.

In MultiSet mode, the requirement applies to individual result sets. (Callers may specify the requirement for each set as it comes up, or let it carry over unchanged.) Any call to this method must follow Execute or ExecuteSP, which reset any such requirements.

SetNullParameter()

CQuery & CQuery::SetNullParameter	(	CTempString	name,
		ESDB_Type	type,
		ESP_ParamType	param_type = eSP_In
	)

Assign null value to the parameter.

Data type should be given explicitly to show which type of data should be sent to server.

Definition at line 4007 of file sdbapi.cpp.

References m_Impl, and CQueryImpl::SetNullParameter().

Referenced by SetOutputParameter().

SetOutputParameter()

CQuery & CQuery::SetOutputParameter ( CTempString  name, ESDB_Type  type  )

inline

Declare an output-only parameter.

Equivalent for now to calling SetNullParameter with a param_type value of eSP_InOut because MSSQL and Sybase (and hence FreeTDS) don't support true output-only parameters. However, if SDBAPI ever gains support for database engines with this feature, this method will arrange to make use of it as appropriate.
