Odpowiedzi:
SELECT Col.Column_Name from
INFORMATION_SCHEMA.TABLE_CONSTRAINTS Tab,
INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE Col
WHERE
Col.Constraint_Name = Tab.Constraint_Name
AND Col.Table_Name = Tab.Table_Name
AND Constraint_Type = 'PRIMARY KEY'
AND Col.Table_Name = '<your table name>'
a
, b
i c
(w tej kolejności), a następnie moja tabela ma klucz podstawowy kompozytowych o abc
?
Ogólnie zaleca się teraz używanie sys.*
widoków INFORMATION_SCHEMA
w SQL Server, więc jeśli nie planujesz migracji baz danych, użyłbym ich. Oto, jak byś to zrobił z sys.*
widokami:
SELECT
c.name AS column_name,
i.name AS index_name,
c.is_identity
FROM sys.indexes i
inner join sys.index_columns ic ON i.object_id = ic.object_id AND i.index_id = ic.index_id
inner join sys.columns c ON ic.object_id = c.object_id AND c.column_id = ic.column_id
WHERE i.is_primary_key = 1
and i.object_ID = OBJECT_ID('<schema>.<tablename>');
Jest to rozwiązanie, które wykorzystuje tylko sys -tables.
Zawiera listę wszystkich kluczy podstawowych w bazie danych. Zwraca schemat, nazwę tabeli, nazwę kolumny i poprawną kolejność sortowania kolumn dla każdego klucza podstawowego.
Jeśli chcesz uzyskać klucz podstawowy dla określonej tabeli, musisz przefiltrować SchemaName
i TableName
.
IMHO, to rozwiązanie jest bardzo ogólne i nie używa żadnych literałów ciągów, więc będzie działać na dowolnej maszynie.
select
s.name as SchemaName,
t.name as TableName,
tc.name as ColumnName,
ic.key_ordinal as KeyOrderNr
from
sys.schemas s
inner join sys.tables t on s.schema_id=t.schema_id
inner join sys.indexes i on t.object_id=i.object_id
inner join sys.index_columns ic on i.object_id=ic.object_id
and i.index_id=ic.index_id
inner join sys.columns tc on ic.object_id=tc.object_id
and ic.column_id=tc.column_id
where i.is_primary_key=1
order by t.name, ic.key_ordinal ;
Oto inny sposób z pytania, aby uzyskać klucz podstawowy tabeli za pomocą zapytania sql :
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE OBJECTPROPERTY(OBJECT_ID(CONSTRAINT_SCHEMA+'.'+CONSTRAINT_NAME), 'IsPrimaryKey') = 1
AND TABLE_NAME = '<your table name>'
Używa KEY_COLUMN_USAGE
do określenia ograniczeń dla danej tabeli.
Następnie używa do określenia, czy każdy jest kluczem podstawowymOBJECTPROPERTY(id, 'IsPrimaryKey')
Korzystając z MS SQL Server możesz:
--List all tables primary keys
select * from information_schema.table_constraints
where constraint_type = 'Primary Key'
Możesz również filtrować według kolumny nazwa_tabeli, jeśli chcesz mieć określoną tabelę.
- To jest kolejna zmodyfikowana wersja, która jest również przykładem dla zapytania związanego
SELECT TC.TABLE_NAME as [Table_name], TC.CONSTRAINT_NAME as [Primary_Key]
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS TC
INNER JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE CCU
ON TC.CONSTRAINT_NAME = CCU.CONSTRAINT_NAME
WHERE TC.CONSTRAINT_TYPE = 'PRIMARY KEY' AND
TC.TABLE_NAME IN
(SELECT [NAME] AS [TABLE_NAME] FROM SYS.OBJECTS
WHERE TYPE = 'U')
Powinno to zawierać listę wszystkich ograniczeń (klucz podstawowy i klucze obce), a na końcu zapytania podać nazwę tabeli

Dzięki Guy.
Z niewielkimi różnicami użyłem go do znalezienia wszystkich kluczy podstawowych dla wszystkich tabel.
SELECT A.Name,Col.Column_Name from
INFORMATION_SCHEMA.TABLE_CONSTRAINTS Tab,
INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE Col ,
(select NAME from dbo.sysobjects where xtype='u') AS A
WHERE
Col.Constraint_Name = Tab.Constraint_Name
AND Col.Table_Name = Tab.Table_Name
AND Constraint_Type = 'PRIMARY KEY '
AND Col.Table_Name = A.Name
SELECT A.TABLE_NAME as [Table_name], A.CONSTRAINT_NAME as [Primary_Key]
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS A, INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE B
WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' AND A.CONSTRAINT_NAME = B.CONSTRAINT_NAME
Ten daje kolumny, które są PK.
SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE WHERE TABLE_NAME = 'TableName'
Poniżej zapytania będzie lista kluczy podstawowych z określonej tabeli :
SELECT DISTINCT
CONSTRAINT_NAME AS [Constraint],
TABLE_SCHEMA AS [Schema],
TABLE_NAME AS TableName
FROM
INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
TABLE_NAME = 'mytablename'
Mówię prostą technikę, którą śledzę
SP_HELP 'table_name'
uruchom ten kod jako zapytanie. Wymień nazwę swojej tabeli w miejscu nazwa_tabeli, dla której chcesz znać klucz podstawowy (nie zapomnij o pojedynczych cudzysłowach). Wynik będzie wyglądał jak załączony obraz. Mam nadzieję, że to ci pomoże
Aby uzyskać listę oddzielonych przecinkami kolumn klucza podstawowego dla danego TableName i Schema:
Select distinct SUBSTRING ( stuff(( select distinct ',' + [COLUMN_NAME]
from INFORMATION_SCHEMA.KEY_COLUMN_USAGE
where OBJECTPROPERTY(OBJECT_ID(CONSTRAINT_SCHEMA + '.' + QUOTENAME(CONSTRAINT_NAME)), 'IsPrimaryKey') = 1
AND TABLE_NAME = 'TableName' AND TABLE_SCHEMA = 'Schema'
order by 1 FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,0,'' )
,2,9999)
Spróbuj:
SELECT
CONSTRAINT_CATALOG AS DataBaseName,
CONSTRAINT_SCHEMA AS SchemaName,
TABLE_NAME AS TableName,
CONSTRAINT_Name AS PrimaryKey
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE CONSTRAINT_TYPE = 'Primary Key' and Table_Name = 'YourTable'
Ta wersja wyświetla schemat, nazwę tabeli i uporządkowaną listę kluczy podstawowych oddzielonych przecinkami. Object_Id () nie działa dla serwerów odsyłających, więc filtrujemy według nazwy tabeli.
Bez REPLACE (Si1.Column_Name, '', '') pokazywałoby otwierające i zamykające tagi XML dla Column_Name w bazie danych, na której testowałem. Nie jestem pewien, dlaczego baza danych wymagała zastąpienia kolumny „nazwa_kolumny”, więc jeśli ktoś wie, to proszę o komentarz.

I ten sam wzorzec, używając zapytania George'a:

Znalazłem to przydatne, podaje listę tabel z przecinkami oddzielną listę kolumn, a następnie również oddzielną przecinkami listę, które są kluczem podstawowym
SELECT T.TABLE_SCHEMA, T.TABLE_NAME,
STUFF((

ORDER BY T.TABLE_SCHEMA, T.TABLE_NAME
Tabela Sys.Objects zawiera wiersz dla każdego zdefiniowanego przez użytkownika obiektu o zasięgu schematu.
Ograniczenia utworzone jak klucz podstawowy lub inne będą obiektem, a nazwa tabeli będzie obiektem nadrzędnym
Zapytaj o sys.Objects i zbierz identyfikatory obiektu wymaganego typu
declare @TableName nvarchar(50)='TblInvoice' -- your table name
declare @TypeOfKey nvarchar(50)='PK' -- For Primary key
SELECT Name FROM sys.objects
WHERE type = @TypeOfKey
AND parent_object_id = OBJECT_ID (@TableName)
Czy mogę zasugerować dokładniejszą prostą odpowiedź na pierwotne pytanie poniżej

AND cons.CONSTRAINT_NAME = keys.CONSTRAINT_NAME
WHERE cons.CONSTRAINT_TYPE = 'PRIMARY KEY'
Uwagi:
Może zostać niedawno opublikowane, ale mam nadzieję, że pomoże to komuś zobaczyć listę kluczy podstawowych na serwerze sql za pomocą tego zapytania t-sql:
SELECT schema_name(t.schema_id) AS [schema_name], t.name AS TableName,
COL_NAME(ic.OBJECT_ID,ic.column_id) AS PrimaryKeyColumnName,
i.name AS PrimaryKeyConstraintName
FROM sys.tables t
INNER JOIN sys.indexes AS i on t.object_id=i.object_id
INNER JOIN sys.index_columns AS ic ON i.OBJECT_ID = ic.OBJECT_ID
AND i.index_id = ic.index_id
WHERE OBJECT_NAME(ic.OBJECT_ID) = 'YourTableNameHere'
Możesz zobaczyć listę wszystkich kluczy obcych, używając tego zapytania, jeśli chcesz:
SELECT
f.name as ForeignKeyConstraintName
,OBJECT_NAME(f.parent_object_id) AS ReferencingTableName
,COL_NAME(fc.parent_object_id, fc.parent_column_id) AS ReferencingColumnName
,OBJECT_NAME (f.referenced_object_id) AS ReferencedTableName
,COL_NAME(fc.referenced_object_id, fc.referenced_column_id) AS
ReferencedColumnName ,delete_referential_action_desc AS
DeleteReferentialActionDesc ,update_referential_action_desc AS
UpdateReferentialActionDesc
FROM sys.foreign_keys AS f
INNER JOIN sys.foreign_key_columns AS fc
ON f.object_id = fc.constraint_object_id
--WHERE OBJECT_NAME(f.parent_object_id) = 'YourTableNameHere'
--If you want to know referecing table details
WHERE OBJECT_NAME(f.referenced_object_id) = 'YourTableNameHere'
--If you want to know refereced table details
ORDER BY f.name
Znalazłem to od mojego przyjaciela, bardzo skuteczne, jeśli szukasz wszystkich kluczy podstawowych tabeli w określonym schemacie.
SELECT tc.constraint_name AS IndexName,tc.table_name AS TableName,tc.table_schema
AS SchemaName,kc.column_name AS COLUMN_NAME

AND kc.constraint_name = tc.constraint_name AND tc.table_schema='<SCHEMA_NAME>'

select

, NUMERIC_PRECISION
from

order by
