Incorrect syntax near ''

问题

I'm trying to run the following fairly simple query in SQL Server Management Studio:

SELECT TOP 1000 * 
FROM 
    master.sys.procedures as procs
left join 
    master.sys.parameters as params on procs.object_id = params.object_id

This seems totally correct, but I keep getting the following error:

Msg 102, Level 15, State 1, Line 6
Incorrect syntax near ''.

It works if I take out the join and only do a simple select:

SELECT TOP 1000 *
FROM 
    master.sys.procedures as procs

But I need the join to work. I don't even have the string '' in this query, so I can't figure out what it doesn't like.

Such unexpected problems can appear when you copy the code from a web page or email and the text contains unprintable characters like individual CR or LF and non-breaking spaces.

Panagiotis Kanavos is right, sometimes copy and paste T-SQL can make appear unwanted characters...

I finally found a simple and fast way (only Notepad++ needed) to detect which character is wrong, without having to manually rewrite the whole statement: there is no need to save any file to disk.

It's pretty quick, in Notepad++:

Click "New file"
Check under the menu "Encoding": the value should be "Encode in UTF-8"; set it if it's not
Paste your text
From Encoding menu, now click "Encode in ANSI" and check again your text

You should easily find the wrong character(s)

The error for me was that I read the SQL statement from a text file, and the text file was saved in the UTF-8 with BOM (byte order mark) format.

To solve this, I opened the file in Notepad++ and under Encoding, chose UTF-8. Alternatively you can remove the first three bytes of the file with a hex editor.

I was using ADO.NET and was using SQL Command as:

 string query =
"SELECT * " +
"FROM table_name" +
"Where id=@id";

the thing was i missed a whitespace at the end of "FROM table_name"+ So basically it said

string query = "SELECT * FROM table_nameWHERE id=@id";

and this was causing the error.

Hope it helps

I got this error because I pasted alias columns into a DECLARE statement.

DECLARE @userdata TABLE(
f.TABLE_CATALOG nvarchar(100),
f.TABLE_NAME nvarchar(100),
f.COLUMN_NAME nvarchar(100),
p.COLUMN_NAME nvarchar(100)
)
SELECT * FROM @userdata

ERROR: Msg 102, Level 15, State 1, Line 2 Incorrect syntax near '.'.

DECLARE @userdata TABLE(
f_TABLE_CATALOG nvarchar(100),
f_TABLE_NAME nvarchar(100),
f_COLUMN_NAME nvarchar(100),
p_COLUMN_NAME nvarchar(100)
)
SELECT * FROM @userdata

NO ERROR
