PolarDB:SHOW GLOBAL INDEX

Sintaksis

SHOW GLOBAL {INDEX | INDEXES} [FROM [schema_name.]tbl_name]

schema_name dan tbl_name bersifat opsional. Abaikan keduanya untuk menampilkan daftar GSI dari semua tabel dalam database saat ini. Sertakan schema_name untuk mengkueri tabel di database lain.

Contoh:

-- Menampilkan semua GSI dalam database saat ini
SHOW GLOBAL INDEX;

-- Menampilkan GSI pada tabel tertentu dalam database saat ini
SHOW GLOBAL INDEX FROM xxx_tb;

-- Menampilkan GSI pada tabel di database lain (kueri lintas-database)
SHOW GLOBAL INDEX FROM xxx_db.xxx_tb;

Contoh output

mysql> show global index;
