Описание

string pg_field_type ( resource result, int field_number )

pg_field_type() returns a string containing the base type name of the given field_number in the given PostgreSQL result resource.

Замечание: If the field uses a PostgreSQL domain (rather than a basic type), it is the name of the domain's underlying type that is returned, rather than the name of the domain itself.

Замечание: This function used to be called pg_fieldtype().

  int8 (bigint)
  numeric
  float4 (real / float)
  float8 (double)
