varchar值的转换溢出了sql server 2012中的int列

Question

I'm getting an error with a query to get data... The error message is: Msg 248, Level 16, State 1, Line 1: The conversion of the varchar value overflowed an int column... I cant resolve this problem, so if any one can help me, thanks in advance, Here is My Sql:

This happens when I inserted 3 new joins in the query, I made them BOLD, otherwise it works perfectly...

SELECT DISTINCT 
   ACR_ART_ID, DES_TEXTS.TEX_TEXT AS CRITERIA_DES_TEXT,
   COALESCE(DES_TEXTS2.TEX_TEXT, ACR_VALUE) AS CRITERIA_VALUE_TEXT,
   (DES_TEXTS.TEX_TEXT + ': ' + COALESCE(DES_TEXTS2.TEX_TEXT, ACR_VALUE)) AS CEL_OPIS
FROM              
   Inventory.dbo.ARTICLE_CRITERIA
LEFT JOIN 
   Inventory.dbo.DESIGNATIONS AS DESIGNATIONS2 ON DESIGNATIONS2.DES_ID = ACR_KV_DES_ID 
LEFT JOIN 
   Inventory.dbo.DES_TEXTS AS DES_TEXTS2 ON DES_TEXTS2.TEX_ID = DESIGNATIONS2.DES_TEX_ID
LEFT JOIN 
   Inventory.dbo.CRITERIA ON CRI_ID = ACR_CRI_ID 
LEFT JOIN 
   Inventory.dbo.DESIGNATIONS ON DESIGNATIONS.DES_ID = CRI_DES_ID
LEFT JOIN 
   Inventory.dbo.DES_TEXTS ON DES_TEXTS.TEX_ID = DESIGNATIONS.DES_TEX_ID
INNER JOIN 
   Inventory.dbo.ART_LOOKUP al ON ARTICLE_CRITERIA.ACR_ART_ID = al.ARL_SEARCH_NUMBER
    AND al.ARL_KIND in (1,3)
INNER JOIN 
   Inventory.dbo.ARTICLES a ON al.ARL_ART_ID = a.ART_ID and (a.ART_SUP_ID=21 or a.ART_SUP_ID=11091)
INNER JOIN 
   Inventory.dbo.SUPPLIERS ON SUPPLIERS.SUP_ID = ART_SUP_ID**
WHERE  
   (DESIGNATIONS.DES_LNG_ID IS NULL OR DESIGNATIONS.DES_LNG_ID = 25)
   AND (DESIGNATIONS2.DES_LNG_ID IS NULL OR DESIGNATIONS2.DES_LNG_ID = 25);

As Commented by @TI

The varchar col is implicitly converted to an int and is overflowing (ie is >larger than 2,147,483,647). To resolve this try casting the columns to bigint

you can cast column value data type as

select cast( max(columnname) AS bigint)+1 from atable ;

But if you will get a varchar than it will fail, with error So it is better to change your DB schema. Use this approach only if you are sure that only numeric string will be present.
