What is the procedure to get the parameter and return types of a stored procedure? (Google is of no help :-( ).
Something along the lines of:
using (var conn = new Npgsql.NpgsqlConnection(connectionString: c))
{
conn.Open();
using (var cmd = con.CreateCommand())
{
cmd.CommandText = "\"GetAllDx\"";
cmd.CommandType = CommandType.StoredProcedure;
cmd.GETPARAMETERS()????????
}
}
PostgreSQL 9.5
Npgsql 3.0.5
Here is one way:
SELECT pg_get_function_result(oid), pg_get_function_arguments(oid)
FROM pg_proc
WHERE proname = 'GetAllDx'
You may also find this useful (although this query returns more than you've asked for):
SELECT oid::regprocedure FROM pg_proc WHERE proname = 'GetAllDx'
