TDE - Remove schema name and view name in column name - sql

Question

I'm trying to create an simple SQL TDE template for XML documents in Marklogic DB.
Sample template:
<template xmlns="http://marklogic.com/xdmp/tde">
<context>/match</context>
<collections>
<collection>source1</collection>
</collections>
<rows>
<row>
<schema-name>soccer</schema-name>
<view-name>matches</view-name>
<columns>
<column>
<name>id</name>
<scalar-type>long</scalar-type>
<val>id</val>
</column>
<column>
<name>document</name>
<scalar-type>string</scalar-type>
<val>docUri</val>
</column>
<column>
<name>date</name>
<scalar-type>date</scalar-type>
<val>match-date</val>
</column>
<column>
<name>league</name>
<scalar-type>string</scalar-type>
<val>league</val>
</column>
</columns>
</row>
</rows>
</template>
I have inserted a sample document in the content database and the above template into Schemas database.
Now I'm trying to run a SQL query using XQuery as below:
xdmp:sql("select * from matches","map")
The above query returns the below response
soccer.matches.id
soccer.matches.document
soccer.matches.date
soccer.matches.league
1234567
/soccer/match/1234567.xml
2016-01-12
Premier
In json format it is,
[
{
"soccer.matches.id": 1234567,
"soccer.matches.document": "/soccer/match/1234567.xml",
"soccer.matches.date": "2016-01-12",
"soccer.matches.league": "Premier"
}
]
In the above response the key name is returned as schema-name.view-name.column_name.E.g.,soccer.matches.id
But I need the key name to have only the column name.E.g., "id": 1234567
Could anyone please share the easiest way to achieve this in XQuery?

You could probably se the names in the SQL statement using AS. You could always iterate over thr the results in a FLWOR statement to modify your results.
However, I suggest that you use the optic API and tune the results as you wish.
Using an op:from-view would be the suggested course of action. You could still use op:from-sql(). In both cases, experiment with the qualifier parameter including omitting it . For the final results, you can use an op:as() with op:select() or op:group-by() to define exactly what you want.
