Hi,

In a table there is a column as Formulae varchar(50), When the data getting inserted column can have data as "(TP*12.00)+12". So in procedure user send in parn TP value.

First of all the TP has to be replaced with In parn value, then procedure need to value then return final value.

For Ex:
TP [In Parn] = 1.5

"(TP*12.00)+12" => (1.5*12.00)+12
return value as 30

pl. help how can I achieve this,

Thanks

It's not going to be easy. You either have to build your own parser or use dynamic sql exec() to do it.

Only way is using Dynamic sql

declare @data varchar(50)
select @data='(TP*12.00)+12'
select @data='select '+replace(@data,'TP','1.5')
exec(@data)

But if you put them in each column, it would be easier
