After this point you will need to drop any indexes and triggers
E.G of recreating the phone tables
 
  SELECT * INTO Phone_new1 FROM phone
 
  SELECT * INTO PhoneLink_new1 FROM PhoneLink
   
  EXEC sp_rename 'Phone', 'Phone_old1'
  go
 
  EXEC sp_rename 'Phone_new1', 'Phone'
  go
 
  EXEC sp_rename 'PhoneLink', 'PhoneLink_old1'
  go
 
  EXEC sp_rename 'PhoneLink_new1', 'PhoneLink'
  go

To get the reference id via SQL you run the code as follows:

 Declare @id nvarchar(128) 
 DECLARE @return_value int 
 execute @return_value = [eware_default_values] 'Cases', 'Case_CaseId', 'Case_ReferenceId', 00, @default_value = @id output 
 select id = @id

to run this code in ASP you would have to create the case record using "CreateRecord" and then update the case_referenceid

 var _sp='Declare @id nvarchar(128) '+
       'DECLARE @return_value int  '+
 'execute @return_value = [eware_default_values] \'Cases\', \'Case_CaseId\', \'Case_ReferenceId\', 00, @default_value = @id output  '+
 'select id = @id '+
 'update Cases '+
 'set Case_ReferenceId=@id '+
 'where Case_CaseId=1';
 var rec=CRM.ExecSQL(_sp);



If you need to re-create a table (say the triggers are corrupted or not running for example) you can do the following.

Copy a table into new table with/without data - SQL Server

Copy only the structure of an existing table into new table:

 SELECT * INTO tblNew FROM tblOld WHERE 1=2

The above query will copy the structure of an existing table(tblOld) into the new table(tblNew).

Copy only the structure with data of an existing table into new table:

 SELECT * INTO tblNew FROM tblOld

E.G of recreating the phone tables

 SELECT * INTO Phone_new1 FROM phone
 
 SELECT * INTO PhoneLink_new1 FROM PhoneLink
   
 EXEC sp_rename 'Phone', 'Phone_old1'
 go
 
 EXEC sp_rename 'Phone_new1', 'Phone'
 go
 
 EXEC sp_rename 'PhoneLink', 'PhoneLink_old1'
 go
 
 EXEC sp_rename 'PhoneLink_new1', 'PhoneLink'
 go
