SQL 挖掘过去 n 年的数据时出现算术溢出错误

Question

im new to SQL. I am trying to extract data from a table for the last 4 years but I am getting the below error

SELECT * FROM fact.ClaimDetail WHERE EobPrintDateCode > DATEADD(year,-4,GETDATE())

Msg 8115, Level 16, State 2, Line 30
Arithmetic overflow error converting expression to data type datetime.

The date format is as below YYYMMDD

df['EobPrintDateCode']
Out[89]: 
0    20060113
1    20060113
2    20060113
3    20060113
4    20060113

Do I need to convert this to another format before I do my select query? Please help

Answer 1

If your datecode is an integer, you can convert it to a date in a two-step process:

SELECT *
FROM fact.ClaimDetail
WHERE TRY_CONVERT(date, TRY_CONVERT(VARCHAR(255), EobPrintDateCode)) > DATEADD(year,-4, GETDATE())

You can also phrase this using operations only on GETDATE() . Once again, assuming an integer:

WHERE EobPrintDateCode >= (YEAR(GETDATE()) - 4) * 10000 + MONTH(GETDATE()) * 100 + DAY(GETDATE())

Because you are subtracting 4 years, the date arithmetic just works like this even for leap years.

Answer 2

you can use cast to convert value to date

SELECT *
FROM fact.ClaimDetail
WHERE cast(cast(EobPrintDateCode AS varchar(8)) AS date) > DATEADD(year,-4, GETDATE())

Answer 3

SELECT * 
FROM fact.ClaimDetail 
WHERE year(EobPrintDateCode) > year(getdate())-4;
