how to show columns with two decimal places

HI ,

I've table whose output is some coumns. The colums show 6 digits after decimal point . My problem is i want to show only two digits after decimal point .. How to do using query..

Thanks

From your question i seem that you are having the FLOAT datatype. You can do this in two ways

1) Modify the table column to DECIMAL(10,2), if you always want to have results in the 2 deciaml place

or

2) SELECT cast (2.456576 AS decimal(10,2)), if you want temp. solution.

Note: This will Round-off the values.

You can use the following approaches,

With Rounded Value:

select convert(Numeric(7,2),ColumnName) From TableName

here it will round/adjust your number to 2 digit decimal

Without Rounded Value:

Select Convert(Numeric(7,2), Round(ColumnName,2,1)) From TableName

here it will truncate the number upto 2 digit decimal and it only show the 2 digit dicimal on your output

Two best practices:

1. The best thing to do is change the table to store the data as the datatype you want to use.

2. If the data needs to be stored like this, but you want to display it this way, the absolute best way of doing this is to use the front end to format the data as you want it. The front end already has to work to display the data in some format, so specifying it as you desire will be best

If you need to do it in T-SQL, then the other replies to use CAST is the next best thing.

|||Already my table datatype is fixed i can't change the datatype. I'm just show output in gridview ...Tell me something which can be done in Grid view or else i've change the whole datatype of table|||As suggested by others, i too says "the best place to do this is the FRONT END". As, when the front end read the data from Database, it internally converts the data into its readable form.

ok tell us which Language you are using & its version ?
which Grid ? and other information. like connection type ...etc.

Is this what ou want - SELECT CAST(32.0 * 100/1722 AS decimal(5,2)) ?

always got
1.00, which was not good. However, now I tried 32*100.00 and it worked

In T-SQL we do not denote data types for literal values like, for example,
in C#. So SQL Server uses it's own logic, and takes 32 and 100 as integers.
First operand data type is then used for result as well. You can also check
topics on data types precendence in Books OnLine.

How to set precision of a decimal number

there is a column which type is float in a table, i want to set the precision of its value, for example if its value is 10.333888, i want to get its value as 10.33, how to complete it in a select Sql?

thks

You can change yourcolumn to numeric or decimal data type, for example, decimal(18,2) or numeric(18,2), which will return 10.33 in your case.

You can look up the difference between numeric and float data type from Books Online which covers everything you need for SQL Server.

How to set MONEY data-type to scale 2

Hi All,

Is there a way to set a MONEY datatype to a scale (decimal places) of 2?
The default is set to 4 and I can't seem to find any resources on how to change it.

Do I have to add a check constraint to manually round to 2 decimals??
That seems unneccessary... but if it is, boo-urns to sql server.

thanks!alter the column to decimal(15,2)?

Why is 4 positions a problem?

how to set integer value in buffer

I am trying to set a decimal value to the pipelinecolumn buffer, but it doesnt get set, and the value is NULL.

Here is the portion of the code of what I am trying to do:

if (columnInfos[x].colName.EndsWith("_CRC"))

{

int a;

a_cmp tst = new a_cmp();

a= tst.a_crc32(inputbufferstream); this function returns a integer value

buffer.SetDecimal(colInfo.bufferColumnIndex, Convert.ToDecimal(a));

}

Please let me know how to set a decimal value in the buffer.

That line of code looks correct, assuming the bufferColumnIndex is correct and the column is of type DT_CY, DT_DECIMAL, or DT_NUMERIC.

Are you seeing an exception?

Thanks
Mark

|||

Do you want to set an integer or do you wanta decimal. Subject says one thing, text says another.

An agnostic way of doing this is to just assign direct, e.g.

buffer[colInfo.bufferColumnIndex] = a;
