Delete an Existing Database

{ deleteDataBase }

This will permanently delete a database on the selected data source server.

Method

Input Parameters

Output Response

Notes

This function should be used very cautiously, because it will delete the selected server. This does not apply to MS OLAP, Tabular or Hana databases.

Examples

Data Source Operations (JavaScript):

This example demonstrates how to operate with data sources.

The example uses API authentication driven from JavaScript. See Authentication APIs for alternatives.

// URL of the Pyramid installation and the path to the API 2.0 REST methods
var pyramidURL = "http://mysite.com/api2/";

// step 1: authenticate admin account and get token
// NOTE: callApi method is a generic REST method shown below.
let token = callApi("auth/authenticateUser",{
	"data":{
		"userName":"adminUser",
		"password":"12345678"
	}
},false);
log("got token "+token);

// step 2: find roles in the system
let findRole = callApi("access/getRolesByName",{
	"data": {
		"searchValue": "role1",
		"searchMatchType": 2//SearchMatchType.Equals
	},
	"auth": token // admin token generated above
});
let roleId=findRole.data[0].roleId;
log("found role with id= "+ roleId);

// step 3: add a new data source server (IMDB)
let createDataServer = callApi("dataSources/createDataServer",{
	"serverData": {
		"serverName": "new server",
		"serverType":13,// use the server type enumeration. 13 = IMDB
		"serverIp": "172.29.3.178",
		"port":5060,
		"serverAuthenticationMethod":0,//ServerAuthenticationMethod.UserPassword
		"userName":"default",
		"password":"password",
	},
	"auth": token // admin token generated above
});
let dataServerId=createDataServer.data.modifiedList[0].id;
log("created dataserver= "+ dataServerId);

// step 4: secure server from step 3 with roles
let addRolesToServer = callApi("dataSources/addRolesToServer",{
	"itemRoles": {
		"itemId":dataServerId,
		"itemRolePairList":[{
			"roleId":roleId,
			"accessType":2//AccessType.Read
		}]
	},
	"auth": token
});
log("added role1 to the newly created server");

// step 5: optional: check the roels on the server
let getRolesByServer= callApi("dataSources/getRolesByServer",{
	"serverId": dataServerId,
	"auth": token
});

// step 6: recognize an existing database on the server
//use this method when you want to address the database in Pyramid
let recognizeDataBase = callApi("dataSources/recognizeDataBase",{
	"dataBaseRecognitionObject": {
		"serverId":dataServerId, //this comes from step 3 above
		"dbName":"PyramidDemo"
	},
	"auth": token
});
let databaseId=recognizeDataBase.data.modifiedList[0].id;
log("found database "+databaseId+" at the dataserver");

// step 7: secure the database from step 3 with roles
let addRolesToDataBase = callApi("dataSources/addRolesToDataBase",{
	"itemRoles": {
		"itemId":databaseId,
		"itemRolePairList":[{
			"roleId":roleId,
			"accessType":3//AccessType.Write
		}]
	},
	"auth": token
});

// step 8A: read in an existing data model from a PIE file
let file="http://myOtherSite.com/SampleModel.pie";
let modelData=readPieFile(file);

// step 8B: import the file content into Pyramid
let importModel = callApi("dataSources/importModel",{
	"modelApiObject": {
		"fileZippedData":modelData, //model data from step 8A
		"databaseId":databaseId, //from step 6
		"materializedRoleAssignmentType":3//MaterializedRoleAssignmentType.ForceParentRoles
	},
	"auth": token
}).data;


// step 9: secure the model from step 3 with roles
let addRolesToModel = callApi("dataSources/addRolesToModel",{
	"itemRoles": {
		"itemId":importModel.modelId, //from step 8B
		"itemRolePairList":[{
			"roleId":roleId,
			"accessType":3//AccessType.Write
		}]
	},
	"auth": token
});

//step 10: delete the model
let deleteMaterializedModel = callApi("dataSources/deleteMaterializedModel",{
	"modelId": importModel.modelId,
	"auth": token
});


//step 11: delete the database
let deleteDataBase=callApi("dataSources/deleteDataBase",{
	"databaseId": databaseId,
	"auth": token
});

//step 12: delete the dta source (server)
let deleteDataSource = callApi("dataSources/deleteDataSource",{
	"sourceId": dataServerId,
	"auth": token
});

	document.write(msg);

//example function to read in the contents of a 'PIE' file that contains
//exported Pyramid content.
