Fetch Metadata Test
--DESCRIPTION--
Verifies that "sqlsrv_field_metadata returns" the same number of fields
as "sqlsrv_num_fields".
Verifies the metadata array (NAME, TYPE, SIZE, PRECISION, SCALE and NULLABLE)
for all SQL types currently supported (28 types).
Validates functionality with statement in both prepared and executed state.
