Arithmetic Overflow Fault Converting Numeric To Information Type Numeric Inwards Sql Server
This fault comes when you lot endeavour to shop an out-of-range floating betoken value into a numeric variable. For example, if your NUMERIC or DECIMAL variable is defined every bit NUMERIC(5,2) than the maximum value it tin fit is 999.99, if you lot endeavour to shop something similar 1000.00 thus it volition throw "Arithmetic overflow fault converting numeric to information type numeric". One of the mutual argue of this fault is the ignorance together with misunderstanding of the NUMERIC information type. For example, many SQL Server DBAs together with developers think that a NUMERIC(5,2) variable tin fit a seven digit floating betoken number where five digit is earlier decimal together with ii digits are later the decimal. This is wrong. Influenza A virus subtype H5N1 NUMERIC(5,2) means, the full number of digits inward the value cannot top five together with decimal precision is ii digits i.e. the maximum possible value is 999.99.
Another matter SQL programmers don't know together with retrieve close NUMERIC or DECIMAL information types inward Microsoft SQL Server is that it doesn't throw this fault if you lot specify to a greater extent than digits than permitted later the decimal point, instead it does rounding for instance if you lot shop 100.999 thus it volition shop 101.00 later rounding.
Here is an SQL enquiry to seek out this points:
Output
Arithmetic overflow fault converting numeric to information type numeric.
Explanation:
This fourth dimension SQL Server throws the fault because nosotros are trying to shop k but the maximum value a NUMERIC(5,2) tin fit is 999 earlier the decimal point. You require to growth the width of the variable to shop this number e.g. making @sample NUMERIC(6,2) volition solve this fault every bit shown below:
Here is simply about more SQL queries which volition confirm the behaviour of NUMERIC variable together with its range:
That's all close "Arithmetic overflow fault converting numeric to information type numeric inward SQL Server". You tin run across that movement of the fault is normally out-of-range value for the defined NUMERIC type. Just cheque the source of value together with right or growth the precision degree of your column.
Always retrieve that NUMERIC(5,2) agency full five digits alongside ii digits later the decimal point, together with maximum value it tin fit is 999.99. Beware of rounding due to to a greater extent than additional digits later decimal point, which tin every bit good movement "Arithmetic overflow fault converting numeric to information type numeric" inward Microsoft SQL Server.

Here is an SQL enquiry to seek out this points:
DECLARE @sample NUMERIC(5,2) SET @sample = 1000.554 SELECT @sample
Output
Arithmetic overflow fault converting numeric to information type numeric.

Here is simply about more SQL queries which volition confirm the behaviour of NUMERIC variable together with its range:
DECLARE @sample NUMERIC(5,2) SET @sample = 100.554 // no rounding because the extra digit is less than 5 SELECT @sample AS Result Result 100.55 DECLARE @sample NUMERIC(5,2) SET @sample = 100.555 // rounding volition hap SELECT @sample AS Result Result 100.56 DECLARE @sample NUMERIC(5,2) SET @sample = 100.55 // no rounding because value is nether defined precision SELECT @sample AS Result Result 100.55 DECLARE @sample NUMERIC(5,2) SET @sample = 100.999 // Rounding to nearest value SELECT @sample AS Result Result 101.00 DECLARE @sample NUMERIC(5,2) SET @sample = 999.999 // fault because later rounding value volition live on out-of-range for defined numeric type SELECT @sample AS Result Result Arithmetic overflow fault converting numeric to information type numeric.
