PA_CountTables

version 2003

PA_CountTables → short

The command PA_CountTables returns the number of tables in the database.

Tables are numbered from 1 to N in the order of their creation. The current version of 4D lets programmers create up to 255 tables.

Note that if the virtual structure mode is on, this routine returns the count of virtual tables.

Verifying a table number before calling PA_CreateRecord.

   short Wrap_CreateRecord (short tableNum)
   {
      short   err = eER_NoErr;
 
   // if the table number is less than 0 or higher than
   //  the number of tables, return an error
      if( (tableNum <= 0) || (tableNum > PA_CountTables) )
         return MY_CONSTANT_BAD_TABLE_NUMBER;
   // OK, lets create the record
      PA_CreateRecord(tableNum);
      return PA_GetLastError();
   }
