The importline statement imports a line of text into the current record.
This statement has three parameters:
text – text to import. (If you want to import text from a file, use the fileload( function to generate this parameter value).
option – An option for customizing the way the import works. See below for descriptions of each option. The option can be specified in either upper or lower case.
value – The value for this option.
This statement imports text into the current record, replacing whatever is already in the record. The text should be a single line organized into fields separated either by commas (often called comma separated text, or CSV), or by tabs. In its simplest form you simply supply the data to be imported:
importline "Wilson,Smith,289 Markle Place,Pleasantville,AX"
In addition to the text to import, you can also specify multiple option/value pairs in a single importline statement, like this:
The possible options are separator, quote, excessfieldserror, addfields and rearrange. Each of these options is described in detail below.
This option is used to explicitly specify the column separator character, for example comma, tab, or semicolon.
importtext sometext,"Separator","," ☞ comma separated importtext sometext,"Separator",tab() ☞ tab separated importtext sometext,"Separator",";" ☞ semicolon separated
If the separator parameter is omitted, Panorama will automatically choose the separator to use. It does this by scanning the first line of the text – if it finds one or more tabs, it assumes the text is tab separated. If no tabs are found, it normally will assume the text is comma separated. However, if the decimal point is configured to comma instead of period, it will assume the text is semicolon separated. (The decimal point character is controlled by the Language & Region panel in the System Preferences window.)
When importing comma separated text, the importline statement normally ignores commas inside quoted text. This allows commas to appear in the data itself, like this:
"Washington, George",Virginia "Adams, John",Masachusetts "Jefferson, Thomas",Virginia
Quoted text can also contain quotes, like this:
"Washington said ""I cannot tell a lie""",false
This option allows you to change the quote character, or you can specify
"" to disable this special quote processing altogether, like this:
Note: Special quote processing is normally disabled when importing tab delimited text, you can use this option to enable it.
If the imported text contains more columns than the database, the extra columns are normally ignored. Use this option if you would like an error to occur in this situation:
The next option describes an alternate way to handle excess fields – add them to the database!
The importline statement normally ignores any extra fields in the imported text. Another option is to actually add additional fields to the database to accomodate the extra data.
Any new fields added will be assigned alphabetical field names – E, F, G, H, etc.
Note: The importline statement handles this option differently than the importtext statement. For the importline statement, this option defaults to OFF, and no error is generated if there are excess fields (unless you set the excessfieldserror option, see above).
The importline statement normally imports data in left to right order – the leftmost column of the imported text is imported into the first database field, the next column is imported into the second field, etc. The rearrange option allows this order to be changed, or can even be used to combine, ignore, or otherwise manipulate the imported data as it is brought into the database. (Legacy note: The rearrange option performs the same function as the importusing statement in previous versions of Panorama.)
Using the rearrange option, you specify a formula that is used to process the import data. This formula is “inserted” into the middle of the import process. The formula must be designed to take in a line of text, then transform it into a different line of text. The importline statement uses this formula to transform each raw line of the import data into a new, manipulated line. This new manipulated line is then imported into the database instead of the original line.
Panorama has a two special functions that allow the import translation formula to access the line that has been read from the disk: import( and importcell(. The import( function returns the entire line that has been imported. The importcell( function has one parameter that specifies the number of the cell you want, for example
importcell(14). (Note that importcell( uses 0 for the leftmost field, not 1).
For more information and examples of this option, see the importtext statement.
