TUNJUKKAN HIBAH
Menampilkan hibah untuk pengguna, peran, atau objek. Objek dapat berupa database, skema, tabel, fungsi, atau templat. Saat Anda menentukan objek, seperti tabel atau fungsi, Anda harus memenuhi syarat dengan notasi dua bagian atau tiga bagian. Misalnya, schema_name.table_name atau database_name.schema_name.table_name.
Jika lebih dari 10.000 baris akan dihasilkan dari SHOW GRANTS, maka perintah tersebut menimbulkan kesalahan.
Izin yang diperlukan
Untuk menjalankan SHOW GRANTS bagi pengguna atau peran target, pengguna saat ini harus memenuhi salah satu kriteria berikut:
-
Jadilah superuser
-
Jadilah pengguna target
-
Jadilah pemilik peran target
-
Diberikan peran
SHOW GRANTS untuk objek target hanya akan menampilkan hibah yang terlihat oleh pengguna saat ini. Hibah dapat dilihat oleh pengguna saat ini jika pengguna saat ini memenuhi salah satu kriteria berikut:
-
Jadilah superuser
-
Jadilah pengguna target
-
Diberikan pemilik peran yang diberikan
-
Diberikan peran yang ditargetkan oleh hibah objek
Sintaksis
Berikut ini adalah sintaks untuk menunjukkan hibah pada objek. Perhatikan bahwa cara kedua menentukan fungsi hanya berlaku untuk skema eksternal dan database yang dibuat dari datashare.
SHOW GRANTS ON { DATABASE database_name | FUNCTION {database_name.schema_name.function_name | schema_name.function_name } ( [ [ argname ] argtype [, ...] ] ) | FUNCTION {database_name.schema_name.function_name | schema_name.function_name } | SCHEMA {database_name.schema_name | schema_name} | { TABLE {database_name.schema_name.table_name | schema_name.table_name} | table_name } TEMPLATE {database_name.schema_name.template_name | template_name} } [FOR {username | ROLE role_name | PUBLIC}] [LIMIT row_limit]
Berikut ini adalah sintaks untuk menampilkan hibah untuk pengguna atau peran.
SHOW GRANTS FOR {username | ROLE role_name} [FROM DATABASE database_name] [LIMIT row_limit]
