In SQL Server, how can I find everywhere a column is referenced? [duplicate]

Answer 1

I would like to avoid using sys.sql_dependencies because this feature will be removed in a future version of Microsoft SQL Server. I also cannot use OBJECT_DEFINITION function because all my objects are encrypted. So I came up with the following query which seems pretty simple and works for me so well that I even wrapped it to the function:

-- =============================================
-- Description: Gets all the stored procedures, functions and triggers referencing the specified column.
-- Example:     SELECT * FROM dbo.UFN_GET_SP_FN_TR_REFERENCING_COLUMN(N'dbo', N'MY_TABLE', N'MY_COLUMN');
-- =============================================
CREATE FUNCTION dbo.UFN_GET_SP_FN_TR_REFERENCING_COLUMN 
(
    @SchemaName sysname,
    @TableName sysname,
    @ColumnName sysname
)
RETURNS TABLE
AS 
RETURN

    SELECT R.referencing_schema_name + N'.' + R.referencing_entity_name AS referencing_entity_name
    FROM sys.dm_sql_referencing_entities(@SchemaName + N'.' + @TableName, 'OBJECT') AS R 
        INNER JOIN sys.objects AS O 
            ON R.referencing_id = O.object_id
    WHERE O.[type] IN ('FN'/*SQL scalar function*/, 'IF'/*SQL inline table-valued function*/, 'TF'/*SQL table-valued-function*/, 'P'/*SQL Stored Procedure*/, 'TR' /*SQL DML trigger*/)
          AND EXISTS(SELECT 1 FROM sys.dm_sql_referenced_entities (R.referencing_schema_name + N'.' + R.referencing_entity_name, 'OBJECT') AS RE WHERE RE.referenced_entity_name = @TableName AND RE.referenced_minor_name = @ColumnName);
