Class Description


  SQL statement class for ODBC

  See TSQLStatement class documentation for more details

________________________________________________________________________
TODBCStatement(SQLHSTMT stmt, Int_t rowarrsize, Bool_t errout)
constructor
~TODBCStatement()
destructor
void Close(Option_t *)
 Close statement
Bool_t Process()
 process statement
Int_t GetNumAffectedRows()
get number of affected rows
Bool_t StoreResult()
 Store result of statement processing.
 Results set, produced by processing of statement, can be stored, and accessed by
 TODBCStamenet methoods like NextResultRow(), GetInt(), GetLong() and so on.
Int_t GetNumFields()
return number of fields
const char* GetFieldName(Int_t nfield)
return field name
Bool_t NextResultRow()
next result row
Bool_t ExtractErrors(SQLRETURN retcode, const char* method)
 Extract errors, produced by last ODBC function call
Bool_t NextIteration()
run next iteration
Int_t GetNumParameters()
return number of parameters
void SetNumBuffers(Int_t isize, Int_t ilen)
set number of buffers
void FreeBuffers()
 Free allocated buffers
Bool_t BindColumn(Int_t ncol, SQLSMALLINT sqltype, SQLUINTEGER size)
 Bind result column to buffer. Allocate buffer of appropriate type
Bool_t BindParam(Int_t npar, Int_t roottype, Int_t size)
 Bind query parameter with buffer. Creates buffer of appropriate type
void* GetParAddr(Int_t npar, Int_t roottype, Int_t length)
 Get parameter address
long double ConvertToNumeric(Int_t npar)
convert to numeric type
const char* ConvertToString(Int_t npar)
convert to string
Bool_t IsNull(Int_t npar)
 Verifies if field value is NULL
Int_t GetInt(Int_t npar)
get parameter as integer
UInt_t GetUInt(Int_t npar)
get parameter as unsigned integer
Long_t GetLong(Int_t npar)
get parameter as Long_t
Long64_t GetLong64(Int_t npar)
get parameter as Long64_t
ULong64_t GetULong64(Int_t npar)
get parameter as ULong64_t
Double_t GetDouble(Int_t npar)
get parameter as Double_t
const char* GetString(Int_t npar)
get parameter as string
Bool_t GetBinary(Int_t npar, void* &mem, Long_t& size)
 return parameter as binary data
Bool_t GetDate(Int_t npar, Int_t& year, Int_t& month, Int_t& day)
 return field value as date
Bool_t GetTime(Int_t npar, Int_t& hour, Int_t& min, Int_t& sec)
 return field value as time
Bool_t GetDatime(Int_t npar, Int_t& year, Int_t& month, Int_t& day, Int_t& hour, Int_t& min, Int_t& sec)

 return field value as time stamp
Bool_t SetNull(Int_t npar)
 Set NULL as parameter value
 If NULL should be set for statement parameter during first iteration,
 one should call before proper Set... method to identify type of argument for
 the future. For instance, if one suppose to have double as type of parameter,
 code should look like:
    stmt->SetDouble(2, 0.);
    stmt->SetNull(2);
Bool_t SetInt(Int_t npar, Int_t value)
set parameter as Int_t
Bool_t SetUInt(Int_t npar, UInt_t value)

set parameter as Long_t
Bool_t SetLong64(Int_t npar, Long64_t value)
set parameter as Long64_t
Bool_t SetULong64(Int_t npar, ULong64_t value)
set parameter as ULong64_t
Bool_t SetDouble(Int_t npar, Double_t value)
set parameter as Double_t
Bool_t SetString(Int_t npar, const char* value, Int_t maxsize)
set parameter as string
Bool_t SetBinary(Int_t npar, void* mem, Long_t size, Long_t maxsize)
set parameter value as binary data
Bool_t SetDate(Int_t npar, Int_t year, Int_t month, Int_t day)
 set parameter value as date
Bool_t SetTime(Int_t npar, Int_t hour, Int_t min, Int_t sec)
 set parameter value as time
Bool_t SetDatime(Int_t npar, Int_t year, Int_t month, Int_t day, Int_t hour, Int_t min, Int_t sec)
 set parameter value as date & time
Bool_t SetTimestamp(Int_t npar, Int_t year, Int_t month, Int_t day, Int_t hour, Int_t min, Int_t sec, Int_t frac)
 set parameter value as timestamp
Bool_t IsParSettMode()
{ return fWorkingMode==1; }
Bool_t IsResultSet()
{ return fWorkingMode==2; }
TODBCStatement(SQLHSTMT stmt, Int_t rowarrsize, Bool_t errout = kTRUE)
