Returns the value of a specified field in the current record. An overloaded version that accepts a column name as input is available, but not as efficient.
qid (scalar) – query number.
idx_or_name (scalar or string) – index or name of the field whose value should be returned.
Specifying a string name may result in much slower performance than a numeric index. Use with caution.
The fields are numbered from left to right using the text of the
statement, e.g. in
// Execute query qid = dbExecQuery(db_id, "SELECT forename, surname FROM people"); do while dbQuerySeekNext(qid); // Using field index forename = dbQueryGetField(qid, 1); // Using field index surname = dbQueryGetField(qid, 2); // Using field name forename = dbQueryGetField(qid, "forename"); // Using field name surname = dbQueryGetField(qid, "surname"); endo;
Field 1 is forename and field 2 is surname. Using
SELECT * is not
recommended because the order of the fields in the query is undefined.
