Hi All<br />
<br />
I have a situation where I have 3 datasources in the database expert.<br />
There is a main table which contains a complete list of data that I want ( Ive checked the query, the total number of records agree with the front end and there is no duplicates )<br />
<br />
I have two descriptions fields which are contained in two other command query datasources.<br />
I linked them in the database expert but it ends up excluding 425 records because there are nulls in the main table.<br />
<br />
How do I handle these nulls? I just want no field description to come through if there isnt one... not to exclude the record entirely....<br />
<br />
thanks!<br />

Hi All

I have a situation where I have 3 datasources in the database expert.
There is a main table which contains a complete list of data that I want ( Ive checked the query, the total number of records agree with the front end and there is no duplicates )

I have two descriptions fields which are contained in two other command query datasources.
I linked them in the database expert but it ends up excluding 425 records because there are nulls in the main table.

How do I handle these nulls? I just want no field description to come through if there isnt one... not to exclude the record entirely....

thanks!

Crystal Report Linking where link may contain nulls

Crystal Reports is a business intelligence application from SAP SE. It is used to graphically design data connections and report layouts from a wide range of data sources including Excel spreadsheets, Oracle, SQL Server databases and Access databases, BusinessObjects Enterprise business views, and local file-system information. Report designers can place fields from these sources on the report design surface, and can also deploy them in custom formulas (using either BASIC or Crystal's own syntax), which are then placed on the design surface. Crystal Reports also supports subreports, graphing, and a limited amount of GIS functionality.
