Question

我发现此代码将找到引用单个特定列的任何存储过程。现在我想创建一个查找引用多个特定列的存储过程的文件。

SELECT DISTINCT Name 
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%tbl_name%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%';

如果可能，我有时可以指定列可能来自哪个表（有时是多个表）？

Answer 1

当然，只需扩展您的SQL以包含其他AND子句，如：

SELECT DISTINCT Name 
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%tbl_name%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%Other_tbl_name%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%Other_CreatedDate%';

这会对你有用吗？

另外，除非你的列名是每个表唯一的，否则你可能会得到误报，所以例如tbl_name可能被引用为CreatedDate列，但这并不意味着对CreatedDate的列引用来自tbl_name.CreatedDate。

此外，我不认为这会捕获动态SQL中的任何引用，因为只有文本的引用，并且不能绑定到系统对象。

这应该可以解决问题：

CREATE TABLE dbo.TableA ( RowID INT, Name VARCHAR(20), StartDate DATETIME, EndDate DATETIME )
GO
CREATE TABLE dbo.TableB ( RowID INT, Name VARCHAR(20), StartDate DATETIME, EndDate DATETIME )
GO

CREATE VIEW dbo.ViewA AS SELECT RowID, StartDate, EndDate FROM dbo.TableA;
GO
CREATE VIEW dbo.ViewB AS SELECT RowID, StartDate, EndDate FROM dbo.TableB;
GO

CREATE PROC dbo.ProcA AS
    SELECT RowID, Name, StartDate FROM dbo.TableA
RETURN
GO

CREATE PROC dbo.ProcB AS
    SELECT RowID, Name, StartDate FROM dbo.TableB
RETURN
GO

SELECT  o1.type_desc AS ReferencingObjectType
        ,OBJECT_SCHEMA_NAME(d.[object_id]) AS ReferencingSchema
        ,OBJECT_NAME(d.[object_id]) AS ReferencingObject
        ,COALESCE(COL_NAME(d.[object_id], d.column_id), '(n/a)') AS ReferencingColumn
        ,o2.type_desc AS ReferencedObjectType
        ,OBJECT_SCHEMA_NAME(d.referenced_major_id) AS ReferencedSchema
        ,OBJECT_NAME(d.referenced_major_id) AS ReferencedObject
        ,COALESCE(COL_NAME(d.referenced_major_id, d.referenced_minor_id), '(n/a)') AS ReferencedColumn
        ,d.class_desc
        ,d.is_selected
        ,d.is_updated
        ,d.is_select_all
FROM    sys.sql_dependencies d
        INNER JOIN sys.objects o1 ON o1.[object_id] = d.[object_id]
        INNER JOIN sys.objects o2 ON o2.[object_id] = d.referenced_major_id
WHERE   OBJECT_SCHEMA_NAME(referenced_major_id) = 'dbo'
AND     OBJECT_NAME(referenced_major_id) = 'TableA'
AND     COALESCE(COL_NAME(referenced_major_id, referenced_minor_id), '(n/a)') = 'StartDate'

请注意，sys.sql_dependencies将从SQL Server的未来版本中删除。我尝试使用推荐的目录视图（sys.sql_expression_dependencies）编写等效查询，但这似乎并没有提供所有table.column依赖项。

您需要使用OR运算符代替AND

SELECT name
FROM   sys.procedures
WHERE  Object_definition(object_id) LIKE '%Table1%'
OR Object_definition(object_id) LIKE '%Table2%'
OR Object_definition(object_id) LIKE '%Table3%'
OR Object_definition(object_id) LIKE '%Table4%'

查找引用特定列的存储过程
