Filemaker: values form related table - filemaker

Question

I have 2 tables, DATA and IMAGES, in a relationship based on item_number.
Records in DATA each have 3 records from IMAGES gathered.
For example, a record with item_number 010050 is linked to these records in IMAGES:
010050.eps
010050_table.tif
010050_drawing.png
In the corresponding record in DATA I have the fields:
main
table
drawing
My aim is to set the fields in DATA like:
010050.eps => main
010050_table.tif => table
010050_drawing.png => drawing
I tried:
ExecuteSQL("SELECT filename FROM images WHERE filename = ?"; ""; ""; "010050_drawing")
Who could give me a hint?

Answer 1

I couldn't figure out how I can do that in xslt.
To take a simplified example, suppose you have exported from your Data table, with only two fields included in the export: Data::ItemNumber and Images::FileName. Your raw export would then look something like this (two records shown):
XML
<?xml version="1.0" encoding="UTF-8"?>
<FMPXMLRESULT xmlns="http://www.filemaker.com/fmpxmlresult">
<ERRORCODE>0</ERRORCODE>
<PRODUCT BUILD="" NAME="FileMaker" VERSION=""/>
<DATABASE DATEFORMAT="" LAYOUT="" NAME="" RECORDS="" TIMEFORMAT=""/>
<METADATA>
<FIELD EMPTYOK="YES" MAXREPEAT="1" NAME="ItemNumber" TYPE="NUMBER"/>
<FIELD EMPTYOK="YES" MAXREPEAT="1" NAME="Images::FileName" TYPE="NUMBER"/>
</METADATA>
<RESULTSET FOUND="2">
<ROW MODID="0" RECORDID="1">
<COL>
<DATA>010050</DATA>
</COL>
<COL>
<DATA>010050.eps</DATA>
<DATA>010050_table.tif</DATA>
<DATA>010050_drawing.png</DATA>
</COL>
</ROW>
<ROW MODID="0" RECORDID="2">
<COL>
<DATA>2345</DATA>
</COL>
<COL>
<DATA>2345_extra.gif</DATA>
<DATA>2345_table.gif</DATA>
<DATA>2345_drawing.jpg</DATA>
<DATA>2345.tiff</DATA>
</COL>
</ROW>
</RESULTSET>
</FMPXMLRESULT>
Note the different order as well as the extra image in the second record.
After applying the following stylesheet:
XSLT
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fmp="http://www.filemaker.com/fmpxmlresult"
exclude-result-prefixes="fmp">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<root>
<xsl:for-each select="fmp:FMPXMLRESULT/fmp:RESULTSET/fmp:ROW">
<xsl:variable name="item-no" select="fmp:COL[1]/fmp:DATA"/>
<item>
<number>
<xsl:value-of select="$item-no"/>
</number>
<main>
<xsl:value-of select="fmp:COL[2]/fmp:DATA[starts-with(., concat($item-no, '.'))]"/>
</main>
<table>
<xsl:value-of select="fmp:COL[2]/fmp:DATA[starts-with(., concat($item-no, '_table.'))]"/>
</table>
<drawing>
<xsl:value-of select="fmp:COL[2]/fmp:DATA[starts-with(., concat($item-no, '_drawing.'))]"/>
</drawing>
</item>
</xsl:for-each>
</root>
</xsl:template>
</xsl:stylesheet>
you would obtain:
Result
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item>
<number>010050</number>
<main>010050.eps</main>
<table>010050_table.tif</table>
<drawing>010050_drawing.png</drawing>
</item>
<item>
<number>2345</number>
<main>2345.tiff</main>
<table>2345_table.gif</table>
<drawing>2345_drawing.jpg</drawing>
</item>
</root>

Answer 2

Honestly, unless there's more happening than what you've described, you're making this too hard.
If there will always be exactly 3 IMAGE records for each DATA record, and especially if you want to directly relate each image to a specific type, you don't need the IMAGE table. A much simpler solution would be to add 3 container fields to your DATA table (say, main_image, table_image, drawing_image). You wouldn't need SQL or a portal, and you wouldn't have to worry about keeping related images linked to their type.
OTOH, if you truly need a separate table, consider hard-wiring three dedicated 1:1 relationships, one for each image type. To do this, add 3 special key fields in DATA: (main_image_id, etc.) and create a relationship for each image type, each between one of these fields and the primary IMAGE. Then, whenever you create a DATA record and 3 related IMAGE records, put the key of the matching image in the matching DATA::xxx_image_id field. That way, you'd have a clean 1:1 relationship, and each related image would be locked to its type.

Answer 3

thanks for your replies
I need the value of the images in those fields to get it exported to XML and InDesign (into table cells).
The issue is that I know the filenames , namely the item_number followed by _drawing or _table, but don't know the extension on forehand (many files and from different sources)
File formats differ therefore.
My solution now is:
- imported all the images in a related (item_number, his is also part of the filename) a FMP table
- I calculated whether the file is a table, drawing or illustration and put those values in a field 'kind' by:
Case (
PatternCount ( filename ; "_drawing." ) ;
"drawing" ;
PatternCount ( filename ; "_table." ) ;
"table" ;
Length ( filename )=10 ;
"main" ;
""
)
- then I did the query in each of the fields, main - table - drawing. The one below is the calculation in the 'table' field.
ExecuteSQL("
SELECT path_xml
FROM images
WHERE item_number = ? and kind = ?";
"";""; item_number ; "table"); ""
)
Perhaps a bit clumsy, but it works now.
