ODBC CSV / REST API Driver

ODBC CSV / REST API Driver

ODBC CSV / REST API Driver can be used to read / write data from Web API (Cloud / Internal Data) or Local CSV / TSV files. Easily integrate virtually any Web API inside your BI / ETL / Reporting / Tools or Programming Languages. Write familiar SQL queries to read /write data. This driver supports latest API security standards (i.e. OAuth 2.0, JWT, X509), and optimized for large data files.

This driver is using same high performance data processing engine which was originally developed for CSV / REST Connector in SSIS PowerPack. ODBC PowerPack and SSIS PowerPack, both products share many UI elements and concepts. We wrote many articles to explain various features in one product but concepts are mostly same in both products so hope you can reuse steps explained in different articles even though screenshots /steps may be slightly different.

Integration Scenarios (Reporting / ETL / BI / Programming)

ZappySys ODBC Drivers built using ODBC standard which is widely adopted by industry for a long time. Which mean the majority of BI Tools / Database Engines / ETL Tools already there will support native / 3rd party ODBC Drivers. Below is the small list of most popular tools / programming languages our Drivers support. If your tool / programming language doesn’t appear in the below list, which means we have not documented use case but as long as your tool supports ODBC Standard, our drivers should work fine.

ZappySys ODBC Drivers for REST API, JSON, XML - Integrate with Excel, Power BI, Tableau, QlikView, QlikSense, Informatica PowerCenter, Excel, SQL Server, SSIS, SSAS, SSRS, Visual Studio / WinForm / WCF, Python, C#, VB.net, PHP. PowerShell

SQL Query Language Examples

ZappySys introduced most innovative way to transform your complex API into Flat table using familiar SQL Query Language. Here are some examples of SQL Queries our drivers understand.

To see all examples check this link (JSON / REST examples) Select correct driver node in help file – e.g. JSON here, XML here, CSV here

Familiar SQL Syntax (Where, Group By, Order By)

/* SQL Language Support to query API or JSON/XML Files */
SELECT Country as Invoice_Country, SUM(UnitPrice * Quantity) Total 
FROM value 
WHERE Discount > 0
GROUP BY Country
HAVING SUM(UnitPrice * Quantity)>1000
ORDER BY Total DESC
WITH (SRC='https://services.odata.org/V3/Northwind/Northwind.svc/Invoices?$format=json')

Read from Local File

/* Query JSON/XML File(s) */
SELECT * FROM $ WITH (SRC=@'C:\Data\Customer*_??.json')

GET data from URL (Read Example)

SELECT * FROM value 
WITH ( 
METHOD='GET', 
SRC='https://services.odata.org/V3/Northwind/Northwind.svc/Invoices?$format=json' 
)

POST data to URL (Write Example)

/* Submit data to API - POST Request. You can POST data from file content or supply body as direct string.*/
SELECT * FROM $  
WITH 
(  
 METHOD='POST'  
,HEADER='Content-Type:text/plain||x-hdr1:AAA'  
,SRC='http://httpbin.org/post'  
,BODY='@c:\files\dump.json'  
,IsMultiPart='True'  
)

API Pagination – Paginate based on URL Path (Loop until no record)

This example shows how to paginate API calls where you need to pass page number via URL Path. Driver keeps incrementing page number and calls next URL until last page is detected. There are few ways to indicate last page (e.g. By status code, By row count, By response size). If you don’t specify end detection then it will use default (i.e. No records found).

SELECT * FROM $
WITH (
SRC='https://zappysys.com/downloads/files/test/cust-<%page%>.json'
,PagingMode='ByUrlPath'
,PagingByUrlAttributeName='<%page%>'
,PagingByUrlEndStrategy='DetectBasedOnRecordCount'
,IncrementBy=1
)

Advanced URL JOIN – Pass parent URL data to Child URL

This example shows how to perform URL JOIN. Using this pattern you can pass parent URL data to child API URL in one query. You can pass parent data in child URL or Body (for POST). Placeholder syntax is [$parent_alias.parent_col_name$]. Each level must have ALIAS attribute. For root level you dont have to Prefix JOINxxxxxxx but for any other level you must Prefix JOINxxxxx before each attribute name. For more information on API JOIN Pattern check https://zappysys.com/links/?id=10092

SELECT
c.custid,c.name,c.city
,o.orderid,o.orderdate,o.total
/* ,i.itemid,i.qty,i.shipped */
FROM $
WITH(
--1st level (root)--
Src='https://zappysys.com/downloads/files/test/join/customers.json'
,NextUrlAttributeOrExpr='$.nextpage'
,Filter='$.customers[*]'
,Alias='c'
,WaitTimeMs='500' --2nd level-- --You can pass parent column to child URL using placeholder [$parent_alias.parent_col_name$] syntax (e.g. [$c.custid$] )
,Join1_src='https://zappysys.com/downloads/files/test/join/c[$c.custid$]/orders.json'
,Join1_filter='$.orders[*]'
,Join1_alias='o'
,Join1_NextUrlAttributeOrExpr='$.nextpage'
,Join1_WaitTimeMs='500'
/*
--3rd level--
--You can pass parent column to child URL using placeholder [$parent_alias.parent_col_name$] syntax (e.g. [$c.custid$] and [$o.orderid$])
,Join2_src='https://zappysys.com/downloads/files/test/join/c[$c.custid$]/o[$o.orderid$]/items.json'
,Join2_filter='$.items[*]'
,Join2_alias='i'
,Join2_NextUrlAttributeOrExpr='$.nextpage'
,Join2_WaitTimeMs='500'
--maximum 7 levels deep you can go. Any attributes allowed in WITH clause can be prefixed by by joinN_xxx
-- join3_xxxxx, join4_xxxxxx .......... join7_xxxxx
*/
)

URL JOIN Pattern – Download files to local disk / Use functions

This example shows how to download files to local disk. It first gets records by calling first URL and then pass it to seconds URL. For more information on API JOIN Pattern check https://zappysys.com/links/?id=10092

SELECT a.url,b.data,file_write_binary(base64_to_bytes(b.data) ,'c:\temp\' || name  ) as bytes_written
from $
WITH (
SRC='https://zappysys.com/downloads/files/test/imagelist.json',
FILTER='$.list[*]',
ALIAS='a',

JOIN1_SRC='[$a.url$]',
JOIN1_ALIAS='b',
JOIN1_SaveContentAsBinary='true'
)

Query Large Compressed File (From URL or Local disk)

This example shows how to read very large file from local disk or URL. You can read uncompressed or compressed file (in our example its GZip compressed file). Using –FAST option in your Filter enables Streaming Mode. To use STREAM Mode you must turn off IncludeParentColumns option as per the example.

SELECT * FROM $
--LIMIT 10
WITH(
Filter='$.LargeArray[*]--FAST' --//Adding --FAST option turn on STREAM mode (large files)
,SRC='https://zappysys.com/downloads/files/test/large_file_10k_largearray_prop.json.gz'
--,SRC='C:\Data\large_file*.json.gz'
,IncludeParentColumns='False'  --//This Must be OFF for STREAM mode (read very large files)
,FileCompressionType='GZip' --Zip or None (Zip format only available for Local files)
)
