    Hello all,

    I am trying to select row from a table where the column contains values from a list. I tried the following but that query gave me an error (Conversion failed when converting the varchar value '1 OR [AttributeID] = 3 OR [AttributeID] = 6 OR [AttributeID] = 2808' to data type int.):

    DECLARE @strSearch VARCHAR(100) = '1,3,6,2808'

    SELECT *

    FROM [AttributeList]

    WHERE [AttributeID] = REPLACE(@strSearch, ',', ' OR [AttributeID] = ')

    The [AttributeID] is an integer type column and i use SQL Server 2012.

    Can someone help me with this, and is this the most efficient way to search?

    Best christmas wishes

    Dynamic SQL (watch for SQL injection) or a string splitter function. I recommend the latter. Search this site for 'Delimited8kSplit'

    Oh, and as for why your attempt failed, that equates to this:

    SELECT *

    FROM [AttributeList]

    WHERE [AttributeID] = '1 OR [AttributeID] = 3 OR [AttributeID] = 6 OR [AttributeID] = 2808';

    ie where the attribute is equal to that long string, which I'm sure you'll agree isn't going to do what you want

    Here's the link for the DelimitedSplit8K splitter.

    If you need something more sophisticated or need to handle something longer than 8K bytes, I strongly recommend a CLR.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
