DSQL (datly SQL)

The general structure for DSQL

SELECT mainViewAlias.*  [EXCEPT COLUMN]
[, secondViewAlias.* ]
[, NviewAlias.* ]
FROM (
    SELECT
    ID  [ColumnConfig],
    ...,
     other_column   
    FROM table1
    ) mainViewAlias [ViewConfig],
[
 JOIN (
    SELECT OTHER_ID,
        ...,
        other_column
    FROM table2
    ) secondViewAlias  [ViewConfig] ON mainViewAlias.ID = secondViewAlias.OTHER_ID

]    

Where

• RouteConfig is JSON representation of Route settings i.e {"URI":"app1/view1/{Id}"}
• OutputConfig is JSON representation of Output settings
• ColumnConfig is JSON representation of Column settings i.e {"DataType":"bool"}
• ViewConfig is JSON representation of View settings i.e {"Cache":{"Ref":"aerospike"}}

View SQL column type codec

SELECT

    employee.* EXCEPT DEPT_ID, 
    organization.* 
FROM (SELECT * FROM DEPARMENT t) dept
JOIN (SELECT ID, NAME, DEPT_ID, 
    (CASE WHEN COLUMN_X = 1 THEN
            'x1,x2'
             WHEN COLUMN_X = 2 THEN

    FROM EMP t) employee ON dept.ID = employee.DEPT_ID
JOIN ORG organization ON organization.ID = demp.ORG_ID AND 1=1
WHERE ID = $Id

Supported conversion Codecs

- AsStrings: converts coma separated value into []string

Setting matching URI

/* {"URI":"dept/"} */
SELECT
dept.* EXCEPT ORG_ID
employee.* EXCEPT DEPT_ID
FROM (SELECT * FROM DEPARMENT t) dept               
JOIN (SELECT ID, NAME, DEPT_ID FROM EMP t) employee 
 ON dept.ID = employee.DEPT_ID

Setting data caching

/* {"URI":"dept/", 
   "Cache":{
         "Name": "fs"
         "Location": "/tmp/cache/${view.Name}",
         "TimeToLiveMs": 360000
         }
   } */
SELECT
dept.* EXCEPT ORG_ID
employee.* EXCEPT DEPT_ID
FROM (SELECT * FROM DEPARMENT t) dept                /* {"Cache":{"Ref":"fs"}} */
JOIN (SELECT ID, NAME, DEPT_ID FROM EMP t) employee  /* {"Cache":{"Ref":"fsgit p"}} */
 ON dept.ID = employee.DEPT_ID

/* {"URI":"dept/", 
   "Cache":{
         "Name": "aerospike",
         "Provider": "aerospike://127.0.0.1:3000/test",
         "Location": "${view.Name}",
         "TimeToLiveMs": 360000
         }
   } */
SELECT
dept.* EXCEPT ORG_ID
employee.* EXCEPT DEPT_ID
FROM (SELECT * FROM DEPARMENT t) dept                /* {"Cache":{"Ref":"aerospike"}} */
JOIN (SELECT ID, NAME, DEPT_ID FROM EMP t) employee  /* {"Cache":{"Ref":"aerospike"}} */
 ON dept.ID = employee.DEPT_ID

Setting selector

SELECT
dept.* EXCEPT ORG_ID
employee.* EXCEPT DEPT_ID
FROM (SELECT * FROM DEPARMENT t) dept                /* {"Selector":{"Limit": 40, "Constraints"{"Criteria": false}}} */
JOIN (SELECT ID, NAME, DEPT_ID FROM EMP t) employee  /* {"Selector":{"Limit": 80, "Constraints"{"Criteria": false, "Limit": false, "Offset": false}}} */
 ON dept.ID = employee.DEPT_ID

Persisting routes/config to the local folder
