• GridDB Server: 5.6

QuickStart

Build and Run

1. Execute the command on project directory.

   $ cd webapi-ce
   $ ./gradlew build

   The following jar file is created.

   • webapi-ce/build/libs/griddb-webapi-ce-X.X.X.jar

2. Set the GS_WEBAPI_HOME variable for GridDB WebAPI home directory .

   $ export GS_WEBAPI_HOME=$PWD/..

   Default is /var/lib/gridstore/webapi.

3. Edit parameter files

   Edit the following files on the ${GS_WEBAPI_HOME}/conf directory

   When you change port (default is 8081) used in URI, please do the following steps.
   1. Copy webapi-ce/src/main/resource/application.properties to your working directory
   2. Edit server.port in it

4. Run with Jar

   java -jar ./build/libs/griddb-webapi-ce-X.X.X.jar

Execution Example

GridDB Server need to be started in advance.

1. Create a container

   #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers 
   $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
   '{"container_name":"test", "container_type":"COLLECTION", "rowkey":true, 
   "columns":[{"name":"col1", "type":"STRING", "index":["TREE"]}, 
     {"name":"col2", "type":"INTEGER"}, {"name":"col3", "type":"BOOL"}]}' 
   http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers

2. Append a row data

   #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers/[containerName]/rows 
   $ curl -X PUT --basic -u admin:admin -H "Content-type:application/json" -d 
   '[["value", 1, true]]' 
   http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers/test/rows 

3. Get a row data

   #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers/[containerName]/rows 
   $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
   '{"limit":1000}'
   http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers/test/rows 
   --> {"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
         {"name":"col3","type":"BOOL"}],"rows":[["value",1,true]],"offset":0,"limit":1000,"total":1}

4. Query with TQL

   #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/tql 
   $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
   '[{"name":"test", "stmt":"select *", "columns":[]}]' 
   http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/tql 
   --> [{"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
          {"name":"col3","type":"BOOL"}],"results":[["value",1,true]],"offset":0,"limit":1000000,"total":1}]

5. Query with SQL

   #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/sql/select 
   $ curl -X POST -u admin:admin -H "Content-type:application/json; charset=UTF-8" 
   -d '[{"stmt":"select * from test"}]' 
   http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/sql/select 
   --> [{"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
          {"name":"col3","type":"BOOL"}],"results":[["value",1,true]]}]

6. Update with SQL

   #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/sql/update 
   $ curl -X POST -u admin:admin -H "Content-type:application/json; charset=UTF-8" 
   -d '[{"stmt":"update test set col3 = false where col2 = 1"}]' 
   http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/sql/update 
   --> [{"status":1, "updatedRows":1,
          "stmt":"update test set col3 = false where col2 = 1", "message":null}]
