ibatis - Nested ResultMaps with ambiguous database columns -



ibatis - Nested ResultMaps with ambiguous database columns -

i have couple of nested resultmaps in ibatis have same database column names. causing ambiguity , resulting in wrong result beingness retrieved different database tables.

for e.g., `

<sql namespace="shipment"> <resultmap id="consignment" class="com.model.consignment"> <result property="consignmentid" column="consignment_cd" /> <result property="shipmentcd" column="shipment_cd" /> <result property="shipmentunit" column="shipment_unit" /> <result property="location" resultmap="shipment.size" /> </resultmap> <resultmap id="size" class="com.model.size"> <result property="consignmentid" column="consignment_cd" /> <result property="shipmentcd" column="shipment_cd" /> <result property="shipmentunit" column="shipment_unit" /> </resultmap> </sql>

`

now when write select query joining size & consignment tables, same values shipment code , shipment unit returned, whereas there different values these 2 columns in database. please note need both shipment code , unit both size , consignment levels pulled in single query.

could help me solve problem?

the solution found issue prefixing column names table name or short name. writing queries right?

your select like

select consignment.shipment_cd consignment_shipment_cd, size.shipment_cd size_shipment_cd consignment bring together size on whatever

and yes pretty heavy if want lot of stuff in same query

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
