varchar 值的转换溢出了 sql server 的 int 列

Question

The conversion of the varchar value '82332617284' overflowed an int column.

I have data such as

BreakID = 82332617284

Thus I have line of code to pull out the number only, so it looks like the following:

join dst.ExceptionsDST d on f.BreakOwnerId = replace(substring(d.dstbreakid,charindex('=',d.dstbreakid) + 1,99),' ','')

What do I need to do in order to just pull the numbers and do the join without getting this error?

It is definitely something with this part

replace(substring(d.dstbreakid,charindex('=',d.dstbreakid) + 1,99),' ','')

Answer 1

int is too small a datatype for your number. You'll have to get rid of so big numbers, or change the column datatype to bigint .

Answer 2

It's clear that your value is bigint. Int datatype can't hold it.

For Example, I'm trying to insert your value #t which is int data type. Will end up with same error

create table #t (id int)
insert into #t values(82332617284)

but this wont error out because it is bigint.

create table #t1 (id bigint)
insert into #t1 values(82332617284)

So if you can change your code like below will help,

join dst.ExceptionsDST d on  f.BreakOwnerId = CAST(replace(substring(d.dstbreakid,charindex('=',d.dstbreakid) + 1,99),' ','') as Bigint)

Answer 3

You can use TRY_CONVERT to avoid this error:

SELECT dstbreakid, TRY_CONVERT(INT, SUBSTRING(d.dstbreakid, CHARINDEX('=', d.dstbreakid) + 1, 99))
FROM (VALUES
    ('x = 82332617284 '),
    ('x = 823326172 ')
) d(dstbreakid)

Output:

| dstbreakid      | (No column name) |
|-----------------|------------------|
| x = 82332617284 | NULL             |
| x = 823326172   | 823326172        |

If f.BreakOwnerId is of datatype int then it cannot contain the value 823326172 .
