That's all about "Arithmetic overflow error converting numeric to data type numeric in SQL Server". out -of -range for defined numeric typeĪrithmetic overflow error converting numeric to data type numeric. 999 / / error because after rounding value will be 55 / / no rounding because value is under defined precision 554 / / no rounding because the extra digit is less than 5 SELECT AS Result Here are some more SQL queries which will confirm the behavior of the NUMERIC variable and its range: making NUMERIC(6,2) will solve this error as shown below.Īrithmetic overflow error converting numeric to data type numeric in SQL Server Examples You need to increase the width of the variable to store this number e.g. This time SQL Server throws the error because we are trying to store 1000 but the maximum value a NUMERIC(5,2) can hold is 999 before the decimal point. SELECT overflow error converting numeric to data type numeric. Here is an SQL query to prove these points: the maximum possible value is 999.99.Īnother thing SQL programmers don't know and remember about NUMERIC or DECIMAL data types in Microsoft SQL Server is that it doesn't throw this error if you specify more digits than permitted after the decimal point, instead, it does rounding for example if you store 100.999 then it will store 101.00 after rounding. This is wrong.Ī NUMERIC(5,2) means, the total number of digits in the value cannot exceed 5 and decimal precision is 2 digits i.e. For example, many SQL Server DBAs and developers think that a NUMERIC(5,2) variable can hold a 7 digit floating point number where 5 digits are before the decimal and 2 digits are after the decimal. One of the common reasons for this error is the ignorance and misunderstanding of the NUMERIC data type. For example, if your NUMERIC or DECIMAL variable is defined as NUMERIC(5,2) then the maximum value it can hold is 999.99, if you try to store something like 1000.00 then it will throw "Arithmetic overflow error converting numeric to data type numeric". This error comes when you try to store an out-of-range floating point value into a numeric variable.
