Function documentation

TMySQLStatement(MYSQL_STMT* stmt, Bool_t errout = kTRUE)
 Normal constructor.
 Checks if statement contains parameters tags.
~TMySQLStatement()
 Destructor.
void Close(Option_t* = "")
 Close statement.
Bool_t Process()
 Process statement.
Int_t GetNumAffectedRows()
 Return number of affected rows after statement is processed.
Int_t GetNumParameters()
 Return number of statement parameters.
Bool_t StoreResult()
 Store result of statement processing to access them
 via GetInt(), GetDouble() and so on methods.
Int_t GetNumFields()
 Return number of fields in result set.
const char* GetFieldName(Int_t nfield)
 Returns field name in result set.
Bool_t NextResultRow()
 Shift cursor to nect row in result set.
Bool_t NextIteration()
 Increment iteration counter for statement, where parameter can be set.
 Statement with parameters of previous iteration
 automatically will be applied to database.
void FreeBuffers()
 Release all buffers, used by statement.
void SetBuffersNumber(Int_t n)
 Allocate buffers for statement parameters/ result fields.
const char* ConvertToString(Int_t npar)
 Convert field value to string.
long double ConvertToNumeric(Int_t npar)
 Convert field to numeric value.
Bool_t IsNull(Int_t npar)
 Checks if field value is null.
Int_t GetInt(Int_t npar)
 Return field value as integer.
UInt_t GetUInt(Int_t npar)
 Return field value as unsigned integer.
Long_t GetLong(Int_t npar)
 Return field value as long integer.
Long64_t GetLong64(Int_t npar)
 Return field value as 64-bit integer.
ULong64_t GetULong64(Int_t npar)
 Return field value as unsigned 64-bit integer.
Double_t GetDouble(Int_t npar)
 Return field value as double.
const char * GetString(Int_t npar)
 Return field value as string.
Bool_t GetBinary(Int_t npar, void*& mem, Long_t& size)
 Return field value as binary array.
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 date & time.
Bool_t GetTimestamp(Int_t npar, Int_t& year, Int_t& month, Int_t& day, Int_t& hour, Int_t& min, Int_t& sec, Int_t& )
 Return field value as time stamp.
Bool_t SetSQLParamType(Int_t npar, int sqltype, bool sig, int sqlsize = 0)
 Set parameter type to be used as buffer.
 Used in both setting data to database and retriving data from data base.
 Initialize proper MYSQL_BIND structure and allocate required buffers.
void * BeforeSet(const char* method, Int_t npar, Int_t sqltype, Bool_t sig = kTRUE, Int_t size = 0)
 Check boundary condition before setting value of parameter.
 Return address of parameter buffer.
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 value as integer.
Bool_t SetUInt(Int_t npar, UInt_t value)
 Set parameter value as unsigned integer.
Bool_t SetLong(Int_t npar, Long_t value)
 Set parameter value as long integer.
Bool_t SetLong64(Int_t npar, Long64_t value)
 Set parameter value as 64-bit integer.
Bool_t SetULong64(Int_t npar, ULong64_t value)
 Set parameter value as unsigned 64-bit integer.
Bool_t SetDouble(Int_t npar, Double_t value)
 Set parameter value as double.
Bool_t SetString(Int_t npar, const char* value, Int_t maxsize = 256)
 Set parameter value as string.
Bool_t SetBinary(Int_t npar, void* mem, Long_t size, Long_t maxsize = 0x1000)
 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 = 0)
 Set parameter value as timestamp.
TMySQLStatement(MYSQL_STMT* stmt, Bool_t errout = kTRUE)
 Normal constructor.
 For MySQL version < 4.1 no statement is supported
Bool_t IsSetParsMode()
{ return fWorkingMode==1; }
Bool_t IsResultSetMode()
{ return fWorkingMode==2; }
