Use CR to generate SQL to change selected records.

The database was wrong. We could see it had incorrect values for some of the records. We could write a Crystal Report to find the errors and even to calculate the correct value to put back in the field. So why not use CR to generate the SQL we needed for the update?

Use the error report as the foundation for a new report. Remove all fields and create a new formula that looks like:

“UPDATE myTable SET ThisField=’” + {@NewValue} + “’ WHERE RecordID=” + {Table.RecordID} 

The report is now a long list of SQL UPDATE commands. Export the Report to a Text File and then use the Text in a SQL Query tool. This can update hundred of records with a few mouse clicks.
