问题
I have tried to modify and existing search all tables script that I found (in this answer from 2009) to include INT option, but I'm getting an error:
Msg 4104, Level 16, State 1, Line 1
The multi-part identifier "dbo.ADACS_MAPS" could not be bound.
for every single column in the database when I run it.
ALTER PROC [dbo].[SearchAllTables]
(
@SearchStr nvarchar(100),
@SearchInt int = 0
)

Can somebody please point out what I'm doing wrong, as this (I'm not ashamed to admit) is beyond my knowledge.
You should be able to run this on any DB, so I have not included demo data.
Edit 1:
The only parts I have modified is:
- added the param
- changed the final select from:
EXEC
(
'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630)
FROM ' + @TableName + ' (NOLOCK) ' +
' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
)
to what it is now.
Edit 2:
Found a solution here that works well, but I will work on my script to see why its not working.
Thanks to the first 2 commentators for the assist, I will look at that code a little more closely using the select as suggested.
回答1:
When i am debugging/developing dynamic code i tend to use the print statement to see where my code goes wrong. I break away the procedure and then print the variable containing the dynamic sql. You could also use the debugger.
Whats happening is that in your dynamic code you are searching for a column which does not exist. This happens because you are missing extra quotes to convert into a string. Below is a print of the first bit of dynamic code when i use your procedure on the Northwind database and search for 'cat'.
if exists (SELECT name
FROM SYSOBJECTS
WHERE xtype = 'U'
-- SQL server sees [dbo].[Categories] as a non existing column
and name like trim(']' from SUBSTRING([dbo].[Categories] , 8, 100)))
BEGIN
SELECT '[dbo].[Categories].[CategoryID]', LEFT([CategoryID], 3630)
FROM [dbo].[Categories] (NOLOCK) WHERE
[CategoryID] = 1 END
ELSE
BEGIN SELECT '[dbo].[Categories].[CategoryID]', LEFT([CategoryID], 3630)
FROM [dbo].[Categories] (NOLOCK) WHERE [CategoryID] LIKE '%cat%' END
Below are two changes to your code to make it work. Extra quotes and an extra variable which strips away the schema since the schema is not present in the name column of the table you are looking in.

(
@SearchStr nvarchar(100),
@SearchInt int = 0
