const char* odbx_field_value(
odbx_result_t* result,
unsigned long pos )
Description:
Returns the field value specified by "pos" of the current row. The value of "pos" must be in the range from 0 to odbx_column_count()-1. All values except binary objects are returned as \0 terminated strings but NULL is also a valid field value. Numbers have to be converted to their binary representation before arithmetic operations are allowed.
Parameters:
- result: Object created by odbx_result()
- pos: Column number in the current result set
Return values:
- Address of a string or binary object for the specified field. Is NULL if the field is a NULL value or pos is out of range.
