Linking between two columns not working

[Former Member]

I have 2 columns, they are both patient numbers. One is defined as a string

and the other is defined as Float, null. So the link is not working. What must I do to the one defined as number? It comes from an excel. I have changed the cells there to text, it's showing this change when I upload to SQL Server, but Crystal reports sees it as a number and it won't link on the string column.

Hello Paul,

Crystal only links Columns that have same data type. If you want this to be linked then either you have to convert one of the field in the table itself or in Crystal Database expert do not Join it. In the report Record Selection you can convert the String field to number type and have it compared with other Patient number or Vice Versa.

But this would degrade the performance if you have huge amount of data.

However, since your data is in Excel, it really won't degrade the performance since the join would be done in memory anyway.
