我需要修改数据库,并且需要查找包含列名“sysnames”的所有表。
我还需要在语句中搜索也包含“sysnames”的视图和存储过程,以便我可以相应地更新它们。
这适用于SQL2000。
TIA, DLackey

有些hacky,但你可以使用这些:
select *
from information_schema.columns
where column_name = 'sysnames'
select *
from information_schema.views
where view_definition like '%sysnames%'
select *
from information_schema.routines
where routine_definition like '%sysnames%'

发布此消息后,我刚刚注意到问题中的SQL Server 2000
免责声明。我没有在SQL Server 2000上运行它,所以它可能无法在那里工作。
这里有两个查询可以满足您的需求:
这将在表和视图中找到列,并将返回有用的信息(ObjectType,DataType,Nullable等)
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
+CASE
WHEN sc.column_id IS NULL THEN ''
ELSE ' computed('+ISNULL(sc.definition,'')+')'
END
+CASE
WHEN cc.object_id IS NULL THEN ''
ELSE ' check('+ISNULL(cc.definition,'')+')'
END
AS MiscInfo
FROM sys.columns s
INNER JOIN sys.types t ON s.system_type_id=t.system_type_id and t.is_user_defined=0
INNER JOIN sys.objects o ON s.object_id=o.object_id
INNER JOIN sys.schemas sh on o.schema_id=sh.schema_id
LEFT OUTER JOIN sys.identity_columns ic ON s.object_id=ic.object_id AND s.column_id=ic.column_id
LEFT OUTER JOIN sys.computed_columns sc ON s.object_id=sc.object_id AND s.column_id=sc.column_id
LEFT OUTER JOIN sys.check_constraints cc ON s.object_id=cc.parent_object_id AND s.column_id=cc.parent_column_id
WHERE s.name LIKE '%sysnames%'
查找过程,函数和触发器中的用法
SELECT DISTINCT
LEFT(s.name+'.'+o.name, 100) AS Object_Name,o.type_desc
FROM sys.sql_modules m
INNER JOIN sys.objects o ON m.object_id=o.object_id
INNER JOIN sys.schemas s ON o.schema_id=s.schema_id
WHERE m.definition Like '%sysnames%'
ORDER BY 1
