In OCI (the language is C), how can I know the number of rows fetched by a sql select? I can read the number of columns after executing a query with the OCIAttrGet() on a statement handle with the prameter OCI_ATTR_PARAM_COUNT set, but trying with the same function whit OCI_ATTR_ROW_COUNT I obtain nothing!!!!
please help me! GePs

there are two ways: fetch all rows and keep a counter, or select count(*). If you are not selecting count(*), you will not know how many rows match your query criteria, till you actually fetch the rows.
