Retrieve primary key values

You can use the following example to derive your own scripts to read the primary key values:

1. Start SMA-SM and then log in as an administrator.

2. Navigate to dbdict.

3. Create a testkey table with a primary key defined.

4. Create a detailed form based on the testkey table.

5. Insert several data points into the testkey table.

6. Navigate to ScriptLibrary.

7. Create a new script by copying the code below:

   var retValue;
   var retCode;
   var keyValues = new SCDatum();
   var file = new SCFile("testkey");
   file.doSelect( "true" );
   file.getFirst();
   retValue = system.functions.rtecall("getprimary", retCode, keyValues, file );
   print( "file testkey is ", file );
   print( "The return value of getprimary is ", retValue );
   print( "The value of primary key is ", keyValues );
   

8. Execute the script.  You should see output that resembles the following:

   The value of primary key is  [C++ object SCDatum] - {'12/12/12 00:00:00', "54343"}
   The return value of getprimary is  true
   File testkey is  [C++ object SCFile] - testkey={['12/12/12 00:00:00', "fgdf", , "54343"]}
