I would suggest using ISNUMERIC, however it has several disadvantages that can lead one to a false conclusion.

I would suggest that you read the following article by Jeff Moden to determine to see if it is helpful.

If everything seems to be going well, you have obviously overlooked something.

EXEC Stored_procedure1 ('abc')
EXEC Stored_procedure1 ('123')
EXEC Stored_procedure1 ('abc112')

Yes. The core of the logic is this:

CASE WHEN <string_value> LIKE '%[^0-9]%' THEN <string> ELSE <int> END

For example:

SELECT
data,
CASE WHEN data LIKE '%[^0-9]%' THEN 'string' ELSE 'int' END AS type
FROM (
SELECT 'abc' AS data UNION ALL
SELECT '123' UNION ALL
SELECT 'abc112'
) AS test_data

Will you ever have negative integers?

In SQL 2008 and 2005 a simple SQLCLR function that leverages the TryParse method of the Int32 object is the most complete way to check for whether a string value can be cast to a SQL INTEGER. Here is a SQLCLR for you:

using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;

public partial class UserDefinedFunctions
{
    [Microsoft.SqlServer.Server.SqlFunction]
    
public static SqlBoolean IsInt32(SqlString Input)
    
{
        
if (Input.IsNull)
            
return SqlBoolean.False;
        
else
        
{
            Int32 i
;
            
return Int32.TryParse(Input.Value, out i);
        
}
    }
}



It is worth noting that in SQL 2012 the TRY_PARSE function was added to T-SQL language making this a trivial chore.
