Question

I am trying to execute a SQL-Statement

SELECT * 
FROM Menu
WHERE ISNumeric(Data) = 1
AND Data = 296

where the Data field may contain numeric or non-numeric contents.
But I am getting syntax error something like

Syntax error on converting the varchar-value ‘/home’ in a column of Data type int.

Answer 1

since DATA column is varchar, you need to enclosed the value (296) with single quote

SELECT * 
FROM   Menu
WHERE  ISNumeric(Data) = 1 AND Data = '296'

you can still directly query without using ISNUMERIC here, and increases performance since you don;t have to check every record for numeric values.

Using IsNumeric is pointless, I guess, in your situation.

SELECT * 
FROM   Menu
WHERE  Data = '296'
