Arithmetic overflow error converting expression to data type nvarchar.

  • Is there a way to find the field this error is being generated by? I am trying to bring data from an AS400 to SQL.  I am attempting to convert 3 fields to date formats. I have a staging table that converts them to nvarchar(10) then when inserting into the final table I do IDATE(field) = 1 then I convert to date else I insert null. if I comment out the date fields it still throws that error. I have increased the size of all the fields, most were decimal, char and numeric. I will post the code of original table and staging table.

  • Is your data really double-byte (from double-byte languages like Arabic and Japanese?) If not, just use VARCHAR instead.

  • No it isn't and youre talking about the decimal fields correct?

  • Here is some sample data, I have removed any data that had identifying information, phone numbers and faxs and names and addresses

  • NVARCHAR() fields are text.

  • Yes they are, no calculations will be done on them.

  • few comments on this

    1. do not use nvarchar unless you have double byte data - use varchar instead
    2. do not use names that require use of [] around them - remove the spaces and drop special chars like /
    3.  use clear names
    4. if a field is not used on AS400 do not create it on SQL - that would most likely be the case of the "do not use" and the "filler2"

    Date fields - they look like numbers representing a date on format DDMMYYYY but you need to speak with the owner of the software on the AS400 to confirm this and to see if they have values representing particular dates which you may need to reproduce.

    to convert these dates you should do something like - right('0' + convert(varchar(8), datefield), 8) to get a string representation of the date and then use substrings on it to convert to format yyyymmdd for easy conversion to a date

    DO NOT use isdate - it will return true even for bad representations of a date - e.g. isdate('2007' will yield a valid date)

  • To find out which values are causing the problem, you could use TRY_CAST(YourColumn AS DATE). The values that can't be cast will be null in the new table. Then you can look at the same rows in the originating table to see what was in those columns. Note: this will still allow a few invalid dates through (as mentioned by Frederico regarding ISDATE above).

  • I think you also find that the Date data coming from an AS400 or IBM PowerSystem will contain all 0's for "null" dates.

    Also, don't use VARCHAR(10) to hold string representations of dates.  You're just chewing up an additional 2 bytes (20%) per entry.  Use CHAR(10) instead and, like the other said, don't use NVARCHAR(10) for such things.

    And, seriously... using NVARCHAR(9) for a Zip Code column is just a crazy waste of byte space.
