Dear All,
I need to implement the percentage functionality in T-SQL which is very similar to Excel 2007 where i can round off and display proper value.
And also need to concatenate the % symbol to it,pls help me.
Input Output
Ex: -4.0283739395038591 --> -4%
9.8039215686274508 --> 1%
-6.358128786459309 --> -6%

Ganga

Hi,

This should do it.

DECLARE @table TABLE (number DECIMAL(19,15))

INSERT INTO @table VALUES (-4.0283739395038591)

INSERT INTO @table VALUES (9.803921568627450)

INSERT INTO @table VALUES (-6.358128786459309)

SELECT CONVERT(VARCHAR(4),CONVERT(INT,ROUND(CAST(number AS DECIMAL(4,2)), 0))) + '%'

FROM @table

Thanks,

Simon

This is something that is best left to the presentation layer.

Hi,

I am using the data format as below.

DECLARE @table TABLE (number nvarchar(max))

INSERT INTO @table VALUES (4.5267489711934158E-2)

INSERT INTO @table VALUES (8.8356729975227088E-2)

INSERT INTO @table VALUES (9.9356025758969638E-2)

SELECT CONVERT(VARCHAR(4),CONVERT(INT,ROUND(CAST(number AS DECIMAL(4,2)), 0))) + '%'

FROM @table

But its not returning with proper result.

Completely agree. This is something that should be done in the client app, not in the database.

DECLARE @table TABLE (number nvarchar(max))

Why on earth are you using an NVarchar(max)? Expecting numbers with 2 billion unicode digits somehow?

But its not returning with proper result.

With that level of detail, there's not a chance in hell anyone's going to be able to help you.

A clue:

You need to multiply by 100.0 somewhere in there ! 🙂

Again (as Gail asked), why nvarchar(max)?
