DCS Using Script

DCS now can have data without questionnaire, it's setting by script

DCS using with script, required a workflow. The workflow get 5 parameters:

1: Any parameter you have specified in the setup

2: The DateTime (or Empty) from which to include data in a partial rebuild

3: The Entire array of Non Unique Ids from last rebuild (or empty if full rebuild)

4: The Entire array of Unique Ids from last rebuild (or empty if full rebuild)

5: The extraParameter, can be set when the rebuild is instanciated from cgscript

And must return CustomDataCacheSpecificationBuildResult

The first parameter can be set on UI or by cgscript

Or can set by cgscript:

Dictionary d1 = {"Key1":1, "Key2": 2};
Dictionary d2 = {"": "xxxx"};
DataCacheSpecification dcs = new DataCacheSpecification(dcsRId);
dcs.BuildUsingWorkflowScriptResourceId = workflowRId;
//dcs.BuildUsingWorkflowScriptParameter=1;// number 
//dcs.BuildUsingWorkflowScriptParameter="xyz"; // string 
//dcs.BuildUsingWorkflowScriptParameter={"xyz",1};// array of string and number 
dcs.BuildUsingWorkflowScriptParameter={d1,d2};// array of Dictionary 
dcs.Save();

The fifth parameter can be set when rebuild DCS

dcs.Rebuild(true, true, 0, true, "abc");

Example for using script:

A simple DCS with 5 rows and one column "test"; value for each row is a random number

How to do it:

- Create a new DCS:

+ Choose using script

+ Add a custom column

- Create a workflow and insert the workflow in to the DCS

Code on workflow must return CustomDataCacheSpecificationBuildResult, how many rows on DCS belonging the length of res. In this example, res is returned with array 5 items, therefor the DCS have 5 rows

CustomDataCacheSpecificationBuildResult res = new CustomDataCacheSpecificationBuildResult();
res.NonUniqueIds.AddRange({1,2,3,4,5});
res.Ids.AddRange({5,6,7,8,9});
return res;

Let continue with another example using parameter Add another column "Order" in to the above DCS, value for each row is a text: "Order number 1" to "Order number 5"

Add custom column name "Order", type full column on the DCS:

Because on script of Order custom column, have an undefined variables x, therefore we can not create that Order column on UI, just make by cgscrip:

DataCacheSpecification dcs = new DataCacheSpecification(15640179);
QcsCustomColumn cc = new QcsCustomColumn("Order", "string", true, dcs);
cc.CgScript = "array param = Workflow_getParameters();
Dictionary localCache = param[0];
FullCustomColumnSettings fs = param[1];
array result = {};
number numberRows = fs.UpdatedNumberOfRows;
for(number i = 0; i < numberRows; i++) {

    result.Add(x + convertToString(i+1));
}
return result;";
cc.Save();
dcs.Save();

In workflow, add 1 more line:

res.AddVariableForFullCustomColumns("x", "Order number ");

After rebuild the DCS, "x" will be replace by "Order number "
