AddTable Method

Description
This method adds a parameter to a database.

Usage
OParamArray AddTable(const char *name, int iotype, int servertype, int ArraySize, int ElementSize)

Arguments

name	The parameter name.
value	The initial value of the parameter.
iotype	Specifies whether this parameter is an input variable, an output variable, or both. The value should be one of: OPARAMETER_INVAR // in parameter OPARAMETER_OUTVAR // out parameter OPARAMETER_INOUTVAR // in/out parameter
servertype	The Oracle type of parameter. The value should be one of: OTYPE_VARCHAR2 OTYPE_NUMBER OTYPE_LONG OTYPE_ROWID OTYPE_DATE OTYPE_RAW OTYPE_LONGRAW OTYPE_CHAR OTYPE_MSLABEL
ArraySize	Defines the number of elements in the parameter array. The maximum length of the buffer is 32512 bytes. This parameter is used to calculate the maximum buffer length. The valid range for this parameter depends on the VarType parameter as shown below:

VarType	Dimension
OTYPE_NUMBER	Valid range from 1 to 1477
OTYPE_SINT
OTYPE_FLOAT
OTYPE_UINT
OTYPE_VARCHAR2	Valid range from 1 to 32512. The maximum legal value of Dimension depends on the Size parameter. Size * Dimension should be less than 32512 bytes.
OTYPE_STRING
OTYPE_VARCHAR
OTYPE_CHARZ
OTYPE_CHAR
OTYPE_DATE	Valid range from 1 to 4644.

ElementSize

Defines the size of the array element for character or string type table parameters.

Remarks
These methods attach an OParamArray to an ODatabase. The name argument specifies the name of the parameter. To refer to the value of the OParameter within SQL statements, use :name.

The parameter that is created is referenced by the returned OParamArray object.

Return Value
An OParamArray, which will be open on success, closed on failure.

Example
OSession ses;

ODatabase odb;

long dbopt = 0; //the default is either no option, or the default set

char Msg[255];

char *pCharBuff = NULL;

int empno;

if (ses.Open() != OSUCCESS)

{

AfxMessageBox("session failed to open");

return;

}

odb.Open(ses, "ExampleDb", "scott", "tiger");

if(odb.IsOpen() != TRUE)

{

AfxMessageBox("database failed to open");

return;

}

else

AfxMessageBox("database open succeeded");

OParameterCollection params = odb.GetParameters();

params.Add("ArraySize", 3, OPARAMETER_INVAR, OTYPE_NUMBER);

OParamArray empnoarray = params.AddTable("EMPNOS", OPARAMETER_INVAR, OTYPE_NUMBER, 3);

OParamArray empnamesarray = params.AddTable("ENAMES", OPARAMETER_OUTVAR, OTYPE_VARCHAR2, 3, 10);

// Initialize EMPNOS array elements

empnoarray.SetValue(7698,0);

empnoarray.SetValue(7782,1);

empnoarray.SetValue(7654,2);

if(odb.ExecuteSQL("Begin Employee.GetEmpNamesInArray(:ArraySize, :EMPNOS, :ENAMES); End;" ) != OSUCCESS){

MessageBox("ExecuteSQL failed");

MessageBox(odb.GetServerErrorText());}

else

MessageBox("ExecuteSQL passed");

for (int count=0;count<3;count++){

empnamesarray.GetValue((const char **)&pCharBuff,count) ;

empnoarray.GetValue(&empno,count);

sprintf(Msg, "Emp name for emp#: %d is %s ", empno, pCharBuff);

MessageBox(Msg);
