The <TABLE_INSTANCE> used in the code below is the instance defined in the Table Instance page .

    

        
copy
        

            

        
    
    

         <TABLE_INSTANCE>.getRow(id : Int64, completion: @escaping (Result<ZCatalystRow, ZCatalystError>) -> Void)
    

Parameters:

• id: The unique ROWID of the particular row that needs to be retrieved
• completion: If the operation is successful, the completion block will return the details of the row. Else, it will return an error.

copy
        

            

        
    
    

         ZCatalystApp.shared.getDataStoreInstance().getTableInstance(id: 1096000000002071).getRow(id: 1096000000002845){( result ) in
// Replace this with your Table ID and ROW ID here       
switch result{
  case .success ( let row) :
   print(row.id)
  case .error( let error ) :
   print( "Error occurred >>> \( error )" )
 }
}

copy
        

            

        
    
    

         <TABLE_INSTANCE>.getRows(completion: @escaping (Result<[ZCatalystRow], ZCatalystError>) -> Void)
    

Parameters:

• completion: If the operation is successful, the completion block will return the details of all the rows. Else, it will return an error.

A sample code snippet is shown below:

//Replace this with your table name             
switch result{
  case .success ( let rows) :
   for row in rows{
