Detailed Description

SQL_HANDLE_STMT

Constructor & Destructor Documentation

◆ cODBCStatement()

GrayLib::cODBCStatement::cODBCStatement ( cODBCBase *  pParent,
const cSQLCmd &  oCmd 
)
inline

Member Function Documentation

◆ CloseStatement()

HRESULT GrayLib::cODBCStatement::CloseStatement ( bool  bDrop)
overridevirtual

ISQLStatement Alternate / Replaces ::SQLFreeHandle() for SQL_HANDLE_STMT handle type.

◆ ExecCancel()

void GrayLib::cODBCStatement::ExecCancel ( )
overridevirtual

ISQLStatement

◆ ExecuteAndFetch()

HRESULT GrayLib::cODBCStatement::ExecuteAndFetch ( bool  bResultsExpected)
overridevirtual

ISQLStatement maybe SQL_ATTR_AUTOCOMMIT is in effect? This command may or may not have a data response. select vs insert or exec etc.

◆ FetchNext()

HRESULT GrayLib::cODBCStatement::FetchNext ( bool  bMore = false)
overridevirtual

ISQLStatement

Are there more results for the fetch? Current fetch returned HResult(FACILITY_WIN32,ERROR_DS_BUSY). Not really sure why this happens.

◆ FillException()

virtual HRESULT GrayLib::cODBCStatement::FillException ( cSQLException *  pException = nullptr)
inlineoverridevirtual

Reimplemented from GrayLib::cODBCBase.

◆ GetColumnVar()

bool GrayLib::cODBCStatement::GetColumnVar ( SQL_COLUMN_t  iColumn,
cSQLColumnInfo *  pColInfo,
OUT cVariant &  vValRet 
)
virtual

ISQLStatement Get a field value as a cVariant.

◆ GetColumnVarBlob()

bool GrayLib::cODBCStatement::GetColumnVarBlob ( SQL_COLUMN_t  iColumn,
cSQLColumnInfo *  pColInfo,
OUT cVariant &  vValRet 
)

◆ GetColumnVarNumber()

bool GrayLib::cODBCStatement::GetColumnVarNumber ( SQL_COLUMN_t  iColumn,
cSQLColumnInfo *  pColInfo,
OUT cVariant &  vValRet,
SQL_TYPE_t  nCType 
)

Get a field value as a cVariant. fixed length types can just be poked directly into memory.

◆ GetColumnVarText()

bool GrayLib::cODBCStatement::GetColumnVarText ( SQL_COLUMN_t  iColumn,
OUT cVariant &  vValRet 
)

◆ GetColumnVarTime()

bool GrayLib::cODBCStatement::GetColumnVarTime ( SQL_COLUMN_t  iColumn,
OUT cVariant &  vValRet 
)

◆ GetData_Raw()

void GrayLib::cODBCStatement::GetData_Raw ( SQL_COLUMN_t  iColumn,
SQL_TYPE_t  nType,
OUT void *  pBuffer,
size_t  nSizeBuffer,
OUT INT_PTR *  pnSizeRet 
)

◆ IUNKNOWN_DISAMBIG()

GrayLib::cODBCStatement::IUNKNOWN_DISAMBIG ( SUPER_t  )

◆ ReadColumnCount()

ITERATE_t GrayLib::cODBCStatement::ReadColumnCount ( )
overridevirtual

ISQLStatement Get number of columns not including column 0.

Note
This was SQLNumResultCols()?

◆ ReadColumnInfo()

bool GrayLib::cODBCStatement::ReadColumnInfo ( SQL_COLUMN_t  iColumn,
OUT cSQLColumnInfo &  info 
)
overridevirtual

ISQLStatement

◆ SetSQLAttr()

bool GrayLib::cODBCStatement::SetSQLAttr ( long  nAttribute,
void *  pValue 
)
overridevirtual

cODBCBase

  • nAttribute = SQL_ATTR_CURSOR_SCROLLABLE

Implements GrayLib::cODBCBase.

◆ UpdateColType()

SQL_TYPE_t GRAYCALL GrayLib::cODBCStatement::UpdateColType ( cSQLColumnInfo *  pColInfo)
static

Convert SQL_INTEGER to SQL_C_SLONG
