Member Function Documentation

disconnectAllQueries()

void sptk::PoolDatabaseConnectionQueryMethods::disconnectAllQueries ( )

protected

Close all queries, connected to this connection, free their statements, and empty connected query list.

linkQuery()

bool sptk::PoolDatabaseConnectionQueryMethods::linkQuery ( Query *  q )

protected

Attaches (links) query to the database

notImplemented()

void sptk::PoolDatabaseConnectionQueryMethods::notImplemented ( const String &  methodName ) const

protected

Stub function to throw an exception in case if the called method isn't implemented in the derived class

paramMark()

virtual String sptk::PoolDatabaseConnectionQueryMethods::paramMark ( unsigned  paramIndex )

protectedvirtual

Returns parameter mark

Parameter mark is generated from the parameterIndex.

Parameters

paramIndex

unsigned, parameter index in SQL starting from 0

queryAllocStmt()

virtual void sptk::PoolDatabaseConnectionQueryMethods::queryAllocStmt ( Query *  query )

protectedpure virtual

Allocates an ODBC statement

queryBindParameters()

virtual void sptk::PoolDatabaseConnectionQueryMethods::queryBindParameters ( Query *  query )

protectedpure virtual

Binds the parameters to the query

queryCloseStmt()

virtual void sptk::PoolDatabaseConnectionQueryMethods::queryCloseStmt ( Query *  query )

protectedpure virtual

Closes an ODBC statement

queryColAttributes() [1/2]

virtual void sptk::PoolDatabaseConnectionQueryMethods::queryColAttributes ( Query *  query, int16_t  column, int16_t  descType, char *  buff, int  len  )

protectedpure virtual

In a dataset returned by a query, retrieves the column attributes

queryColAttributes() [2/2]

virtual void sptk::PoolDatabaseConnectionQueryMethods::queryColAttributes ( Query *  query, int16_t  column, int16_t  descType, int32_t &  value  )

protectedpure virtual

In a dataset returned by a query, retrieves the column attributes

queryColCount()

virtual int sptk::PoolDatabaseConnectionQueryMethods::queryColCount ( Query *  query )
