Purpose
Inserts lines into a text file.
Format
@DTWF_INSERT(filename, transform, delimiter, table, retry, rows, startrow)
@DTWF_INSERT(filename, transform, delimiter, table, retry, rows)
@DTWF_INSERT(filename, transform, delimiter, table, retry)
@DTWF_INSERT(filename, transform, delimiter, table)
Parameters
Table 172. DTWF_INSERT Parameters
Data Type | Parameter | Use | Description |
---|---|---|---|
string | filename | INOUT | The name of the file to which records are inserted. On successful completion of the call, this parameter returns the fully qualified file name. |
string | transform | IN | The format of the file:
|
string | delimiter | IN | A character string to indicate the ends of values. This parameter is case sensitive. Ignored if transform is ASCIITEXT. |
table | table | IN | The table variable from which records are inserted into the file.
For non-OS/400 users: The maximum length of a row in an FFI table is 16383 characters. This limit includes a null character for each column in the Net.Data macro table. |
integer | retry | IN | The number of times to retry if the file cannot be written to immediately. The default is not to retry. |
integer | rows | IN | The maximum number of rows to insert from table. The default is to insert all the rows. A value of 0 inserts all the rows. |
integer | startrow | INOUT | The line number from which to begin inserting. If the value is greater than the number of lines in the file, the value is changed to the last record and returned as an error. Specifying 0 means to insert after the beginning of the file. The default is to start at 1. |
Return Codes
Table 173. DTWF_INSERT Return Codes
Return Code | Explanation |
---|---|
-1001 | The server could not process a Net.Data request to allocate memory. |
1001 | An input parameter contained a NULL value. |
1002 | An input parameter contained a string value which consisted of the null-terminating character. |
1003 | The number of parameters passed on a function call either exceeded the maximum number allowed, or was less than the minimum number required by the function. |
1004 | A parameter passed on a function call, required to be a Net.Data macro table variable, was of a different variable type. |
1005 | A parameter passed on a function call, required to be a string variable, was of a different variable type. |
1006 | A literal string was passed on a function call for a parameter which was required to be an output parameter. |
1007 | A parameter contains a value which is not valid. |
2000 | An flat file interface built-in function could not find the specified file. |
2001 | A flat file interface built-in function could not open the specified file because it was in use by this or another process, and could not be shared in the specified mode. |
2003 | A flat file interface built-in function could not read a row of data into a table variable because the number of bytes in the row exceeded the maximum supported number of bytes. |
2004 | A flat file interface built-in function was attempting to find a file, but encountered a path in the FFI_PATH configuration file variable that was longer than the maximum supported number of bytes, which is 4095. |
2005 | A call to a system function failed. |
2006 | A flat file interface built-in function could not access the specified file because it was in use by this or another process and could not be shared in the specified mode. |
Examples
Example 1:
%DEFINE { myFile = "c:/private/myfile" myTable = %TABLE myWait = "3000" %} @DTWF_INSERT(myFile, "Delimited", "|", myTable, myWait)
Example 2:
%DEFINE { myFile = "c:/private/myfile" myTable = %TABLE myStart = "1" myRows = "2" %} @DTWF_INSERT(myFile, "Asciitext", "|", myTable, "0", myRows, myStart)
