Printing SQL in C - c

Question

I'm looking for help with printing the results of an SQL statement out in C. I'm trying not to set each variable to a pointer and then using that pointer to print the variable out. If I did, I'd have like a couple hundred variables. This is what I've tried so far. I'm literally lost on how to get this to output correctly. Any help would be appreciated.
int hstmt = DBActivateSQL(hdbc, "SELECT * FROM REG_RESULTSTABLE");
if (hstmt <= 0)
{
ShowError();
}
sprintf(uutNum, "%s \n", hstmt);
while((resCode = DBFetchNext(hstmt)) == DB_SUCCESS) {
SetCtrlVal(panelHandle, PANEL_lstregulator, uutNum);
}

Answer 1

Prototype of DBActivateSQL is
int DBActivateSQL (int connectionHandle, char SQLStatement[]);
It is returns int.
Hence hstmt should be declared as int type.
int hstmt = DBActivateSQL(hdbc, "SELECT * FROM REG_RESULTSTABLE");
To print it to string you need use %d not %s as hsmt is of type int.
sprintf(uutNum, "%d",hstmt);
^^------------------------//Using %d instead of %s here

The functions that you want are DBFetchNext and DBGetCol* (DBGetColChar, DBGetColDouble, ...). According to the documentation page on DBGetColChar, the flow should be something like this, where you only need one variable per column:
void print_MyTable(int hdbc)
{
char *var1;
int var2;
float var3;
int statement = DBActivateSQL(hdbc, "SELECT col1, col2, col3 FROM MyTable");
int resultCode;
while ((resultCode = DBFetchNext(statement)) == DB_SUCCESS) {
if ((resultCode = DBGetColChar(statement, 1, &var1, "")) != DB_SUCCESS) {
// Handle the error
break;
}
if ((resultCode = DBGetColInt(statement, 2, &var2)) != DB_SUCCESS) {
// Handle the error
DBFree(var1);
break;
}
if ((resultCode = DBGetColFloat(statement, 3, &var3)) != DB_SUCCESS) {
// Handle the error
DBFree(var1);
break;
}
// Print the values
printf("col1: %s, col2: %d, col3: %f\n", var1, var2, var3);
// Free the string's memory
DBFree(var1);
}
statement = DBDeactivateSQL(statement);
}
