The multi-part identifier could not be bound again

问题

I am trying to create a stored procedure like this,

CREATE PROCEDURE [dbo].[SP_Name]
(
    @ID varchar(50),
    @URL varchar(256)
)
AS
    SELECT DISTINCT 
       Table1.CID, Table2.Name, Table2.aID, Table2.bID,
       Table3.SchemeName, Table2.cURL
    FROM Table4
    INNER JOIN Table5 ON Table5.eID = Table1.eID
    INNER JOIN Table2 ON Table2.ID = Table1.CID
    INNER JOIN [Table3] ON Table3.aID = Table2.aID AND Table3.bID = Table2.bID
    WHERE 
        Table5.ID = @ID 
        AND Table2.cURL LIKE '%' + @URL + '%'

but I'm getting this error:

Msg 4104, Level 16, State 1, Procedure SP_Name, Line 7
The multi-part identifier "Table1.eID" could not be bound.
Msg 4104, Level 16, State 1, Procedure SP_Name, Line 7
The multi-part identifier "Table1.cID" could not be bound.
Msg 4104, Level 16, State 1, Procedure SP_Name, Line 7
The multi-part identifier "Table1.cID" could not be bound.

Even though syntax is right.

You have to add inner join with Table1

SELECT DISTINCT Table1.CID, 
Table2.Name, Table2.aID, Table2.bID,
Table3.SchemeName, Table2.cURL

FROM Table4
INNER JOIN Table1 ON ....
INNER JOIN Table5 ON Table5.eID = Table1.eID
INNER JOIN Table2 ON Table2.ID = Table1.CID
INNER JOIN [Table3] ON Table3.aID = Table2.aID AND Table3.bID = Table2.bID

WHERE Table5.ID=@ID AND Table2.cURL LIKE '%' + @URL + '%'

or use Table1 instead of Table4

SELECT DISTINCT Table1.CID, 
Table2.Name, Table2.aID, Table2.bID,
Table3.SchemeName, Table2.cURL

FROM Table1
INNER JOIN Table1 ON ....
INNER JOIN Table5 ON Table5.eID = Table1.eID
INNER JOIN Table2 ON Table2.ID = Table1.CID
INNER JOIN [Table3] ON Table3.aID = Table2.aID AND Table3.bID = Table2.bID
WHERE Table5.ID=@ID AND Table2.cURL LIKE '%' + @URL + '%'
