An incremental query result
DB::DBIncResult< a >
= DBIncRes(DB::DBHandle<a> con,Int rows,Int cols,[String] colnames,Ptr resptr)
DBIncResult holds data about the result of an incremental query, if the database-specific library supports these.
- rows is the number of rows in the result set.
- cols is the number of columns in each row of the result set.
- colnames is a list of the names of the columns
- resptr is an internal pointer kept by the relevant database interface.
An incremental query returns data only one row at a time, which may save memory on large result sets. Depending on the internal implementation in the database-specific library, the rows field may not contain useful information. Database-specific libraries should throw an Exception if an attempt is made to read more rows than exist.
res = incExec(conn,"SELECT id,name FROM People"); row = getRow(res); // row[0] = DBInt(id) // row[1] = DBText(name)
