Pour obtenir le
1) nom complet de la colonne
2) nom de l'objet (y compris le schéma)
3) type d'objet (table/vue)
4) type de données (format agréable : varchar(6) ou numeric(5,2), etc.)
5) nul/non nul
6) informations sur l'identité, la contrainte de contrôle et les informations par défaut.
Essayez ceci :
DECLARE @Search varchar(200)
SET @Search='YourColumnName' --can be a partial or a complete name
SELECT
s.name as ColumnName
,sh.name+'.'+o.name AS ObjectName
,o.type_desc AS ObjectType
,CASE
WHEN t.name IN ('char','varchar') THEN t.name+'('+CASE WHEN s.max_length<0 then 'MAX' ELSE CONVERT(varchar(10),s.max_length) END+')'
WHEN t.name IN ('nvarchar','nchar') THEN t.name+'('+CASE WHEN s.max_length<0 then 'MAX' ELSE CONVERT(varchar(10),s.max_length/2) END+')'
WHEN t.name IN ('numeric') THEN t.name+'('+CONVERT(varchar(10),s.precision)+','+CONVERT(varchar(10),s.scale)+')'
ELSE t.name
END AS DataType
,CASE
WHEN s.is_nullable=1 THEN 'NULL'
ELSE 'NOT NULL'
END AS Nullable
,CASE
WHEN ic.column_id IS NULL THEN ''
ELSE ' identity('+ISNULL(CONVERT(varchar(10),ic.seed_value),'')+','+ISNULL(CONVERT(varchar(10),ic.increment_value),'')+')='+ISNULL(CONVERT(varchar(10),ic.last_value),'null')
END

ELSE ' computed('+ISNULL(sc.definition,'')+')'
END
+CASE
