comment obtenir le nom de schéma de la table

Question

J'utilise SQL Server 2008 et ont la requête suivante:

SELECT SO1.name AS Tab, 
     SC1.name AS Col, 
     SO2.name AS RefTab, 
     SC2.name AS RefCol, 
     FO.name AS FKName 
FROM dbo.sysforeignkeys FK 
INNER JOIN dbo.syscolumns SC1 ON FK.fkeyid = SC1.id AND FK.fkey = SC1.colid 
INNER JOIN dbo.syscolumns SC2 ON FK.rkeyid = SC2.id AND FK.rkey = SC2.colid 
INNER JOIN dbo.sysobjects SO1 ON FK.fkeyid = SO1.id 
INNER JOIN dbo.sysobjects SO2 ON FK.rkeyid = SO2.id 
INNER JOIN dbo.sysobjects FO ON FK.constid = FO.id 

Comment récupérer-vous le nom de schéma de la table?

Merci pour votre aide

Answer 1

Utilisez OBJECT_SCHEMA_NAME

SELECT 
    OBJECT_SCHEMA_NAME(f.parent_object_id) AS TableNameSchema, -- this 
    OBJECT_NAME(f.parent_object_id) AS TableName, 
    COL_NAME(fc.parent_object_id,fc.parent_column_id) AS ColumnName, 
    OBJECT_SCHEMA_NAME(f.referenced_object_id) AS ReferenceTableNameSchema, 
    OBJECT_NAME (f.referenced_object_id) AS ReferenceTableName, 
    COL_NAME(fc.referenced_object_id,fc.referenced_column_id) AS ReferenceColumnName, 
    f.name AS ForeignKey 
FROM 
    sys.foreign_keys AS f 
    INNER JOIN sys.foreign_key_columns AS fc ON f.OBJECT_ID = fc.constraint_object_id 
    INNER JOIN sys.objects AS o ON o.OBJECT_ID = fc.referenced_object_id

Comme par Sql Server 2008:

SELECT Object_name(f.parent_object_id) 
     AS 
     TableName, 
     Col_name(fc.parent_object_id, fc.parent_column_id) 
     AS ColumnName, 
     Object_name (f.referenced_object_id) 
     AS ReferenceTableName, 
     Col_name(fc.referenced_object_id, fc.referenced_column_id) 
     AS 
     ReferenceColumnName, 
     f.name 
     AS ForeignKey, 
     Quotename(Schema_name(f.schema_id)) + '.' + Quotename( 
     Object_name(f.parent_object_id)) AS 
     schemaname, 
     Quotename(Schema_name(o.schema_id)) + '.' + Quotename( 
     Object_name(f.referenced_object_id)) 
             AS ReferenceSchemaName 
FROM sys.foreign_keys AS f 
     INNER JOIN sys.foreign_key_columns AS fc 
     ON f.OBJECT_ID = fc.constraint_object_id 
     INNER JOIN sys.objects AS o 
     ON o.OBJECT_ID = fc.referenced_object_id 

Si vouloir connaître le nom de schéma sur la base de object_id puis utilisez OBJECT_SCHEMA_NAME(), si vous voulez obtenir le nom de schéma sur la base de schema_id puis utilisez SCHEMA_NAME().
