Having issues with UPDATE command

Using this SP I keep getting an error on the UPDATE statement indicating that I have conversion problem or something. But ID is an integer in all of my tables....

Conversion failed when converting the varchar valu开发者_开发技巧e 'UPDATE tblLangenUS SET [lang_String] = ' - asdfgsdfg', [prev_LangString] = ' ', [needsTranslation] = 'false' WHERE [ID] = '' to data type int.

    @currTable varchar(100),
    @ID int,
    @short_Text varchar(250),
    @brief_Descrip varchar(250) = Null,
    @needsTranslation varchar(10) = Null,
    @prev_LangString varchar(250) = Null,
    @lang_String varchar(250) = Null,
    @original_lang_String varchar(250) = Null,
    @StringID_from_Master varchar(250),     
    @GUID varchar(250) = Null

RETURN

If the ID is an int, you must CAST it to an nvarchar

SET @sql = 'UPDATE ' + @currTable + ' SET [lang_String] = ''' + @lang_String + ''', [prev_LangString] = ''' + @prev_LangString + ''', [needsTranslation] = ''' + @needsTranslation + ''' WHERE [ID] = ''' + CAST(@ID as nvarchar(10)) + '''; '

Otherwise, you are trying to add a string and an integer together, which won't work.

Notice this part:

   ' WHERE [ID] = ''' + CAST(@ID as nvarchar(10)) + '''

I think you must also change your EXEC syntax to:

EXEC(@sql)
