<h1 class="topictitle1">Copy database source files to database source files</h1>
|
||
|
|
<div><p>When you copy database source files to database source
|
||
|
|
files, you use SRCOPT(*SEQNBR) and the SRCSEQ parameter to assign sequence
|
||
|
|
numbers to the copied records.</p>
|
||
|
|
<p>You can copy between database source files by using the <a href="../cl/cpysrcf.htm">CPYSRCF</a> or <a href="../cl/cpyf.htm">CPYF</a> command. The CPYSRCF command
|
||
|
|
might be easier to use because the parameter defaults are better suited for
|
||
|
|
copying database source files.</p>
|
||
|
|
<p>If you specify SRCOPT(*SEQNBR) to update the sequence numbers, the server
|
||
|
|
considers the SRCSEQ parameter. The SRCSEQ parameter specifies the starting
|
||
|
|
value that is assigned to the first record that is copied and the increment
|
||
|
|
value. The defaults are 1.00 and 1.00. You can specify a whole number of no
|
||
|
|
more than 4 digits or a fraction of no more than 2 digits for the starting
|
||
|
|
value and the increment value. You must use a decimal point for fractions.</p>
|
||
|
|
<p>For example, if you specify SRCSEQ(100.50), then the records copied will
|
||
|
|
have sequence numbers 100.00, 100.50, 101.00, 101.50, and so on.</p>
|
||
|
|
<p>Suppose that you have a file that contains more than 9999 records. Use
|
||
|
|
a fractional increment value so that each record has a unique sequence number.
|
||
|
|
If you specify a starting value of .01 and an increment value of .01, the
|
||
|
|
maximum number of records copied with unique sequence numbers is 999 999.
|
||
|
|
When the maximum sequence number is exceeded (9999.99), all remaining records
|
||
|
|
on that copy are initialized to 9999.99. The server does not wrap back to
|
||
|
|
1.00.</p>
|
||
|
|
<p>If the database source file that you are copying to has only an arrival
|
||
|
|
sequence access path, the records are always physically placed at the end
|
||
|
|
of the file. (Because the file does not have a keyed sequence access path,
|
||
|
|
you cannot insert records into the middle of the file keyed access path.)</p>
