How to alter the precision of a decimal column in SQL?

Is there a way to alter the precision of an existing decimal column in Sql Server? Just put decimal (precision, scale), replacing the precision and scale with your desired values. I haven’t done any testing with this with data in the table, but if you alter the precision, you would be subject to losing data if the new precision is lower.

How to increase precision or scale of number column?

Another way is to move values into temporary colum, then increase length of ED_RATE and move values back: You need create new table with structure from source table, but with new precision of column ED_DATE. Then copy all data from source table to new table, drop source table and after that rename destination table as source table.

What happens when you add 9 digits of precision?

The 9 digits of precision being added to the column would presumably come at the cost of precision to the left of the decimal place. Hence, this could cause some of your data to be truncated. If you want to add 9 digits of decimal precision, I believe you will have to also increase the total precision. Hence, the following should work:

How to increase precision of column Ed _ date?

You need create new table with structure from source table, but with new precision of column ED_DATE. Then copy all data from source table to new table, drop source table and after that rename destination table as source table. Thanks for contributing an answer to Stack Overflow!

What do precision and scale of a field mean?

Precision and scale of a field describe the precision and the maximum size of data which can be stored in a field. The precision describes the number of digits which can be stored in a field while scale describes the number of decimal places for double and float fields.

Is it possible to change the data type of an existing field?

For more information, read ArcMap Help: ArcGIS field data types. While it is not possible to change the data type of an existing field, the same results can be achieved by transferring attributes from one field/data type to another desired field/data type.

Why is a number field not allowed in ArcMap?

In ArcMap, attempting to insert numbers into an attribute table is not allowed. Instead, a generic error such as the following is returned,”This number field can only have 2 digits to the left of the point.” This occurs due to the difference between the precision and scale of either a float or double type field with the input value.
