Search in what? A column in a table, all columns in a table, all tables in a schema, all tables in a database?

Shows the framework of how to loop through the entire database.  

Just change the last exec statement to not bring back the Left part of the column.

and change the where to @ColumnName = @SearchStr2

ged325,

Real number is approximate not precise,  I need to set a tolerance like  abs(@ColumnName - @SearchStr2)/@SearchStr2 < Tolerance to see if @ColumnName = @SearchStr2.  Tolerance can be 10E-6

In that case do a between:

declare @min
declare @max


set @min = subtract tolerance from value

set @max = add tolerance to value

where @columnName between @min and @max
