I have this query which works well but without parametrization in index. emp is an index, and NUM_OFC_CA is an emp number (key in emp index), to simplify i want to return NME_CA.
curl -X POST http://xyzhost:7474/db/data/ext/CypherPlugin/graphdb/execute_query -H "Content-Type: application/json" --data-binary '{
"query": "START ca=node:emp(\"NUM_OFC_CA: 997015\") RETURN distinct ca.NME_CA as `CA Name`",
"params": {
}
}'
How can i parametrize above REST query, i have tried something like this:
curl -X POST http://xyzhost:7474/db/data/ext/CypherPlugin/graphdb/execute_query -H "Content-Type: application/json" --data-binary '{
"query": "START ca=node:emp(\"NUM_OFC_CA: {num_ofc_ca}\") RETURN distinct ca.NME_CA as `CAName`",
"params": {
"num_ofc_ca": "997015"
}
}'
I am getting this error:
{
"message" : "org.apache.lucene.queryParser.ParseException: Cannot parse 'NUM_OFC_CA: {num_ofc_ca}': Encountered \" \"}\" \"} \"\" at line 1, column 23.\nWas expecting one of:\n \"TO\" ...\n <RANGEEX_QUOTED> ...\n <RANGEEX_GOOP> ...\n ",
"exception" : "BadInputException",
"stacktrace" : [ "org.neo4j.server.plugin.cypher.CypherPlugin.executeScript(CypherPlugin.java:61)", "java.lang.reflect.Method.invoke(Method.java:597)", "org.neo4j.server.plugins.PluginMethod.invoke(PluginMethod.java:57)", "org.neo4j.server.plugins.PluginManager.invoke(PluginManager.java:168)", "org.neo4j.server.rest.web.ExtensionService.invokeGraphDatabaseExtension(ExtensionService.java:300)", "org.neo4j.server.rest.web.ExtensionService.invokeGraphDatabaseExtension(ExtensionService.java:122)", "java.lang.reflect.Method.invoke(Method.java:597)" ]
}
Need help to resolve this issue. Thanks!
If you need a plain index query, the syntax is as follows:
curl -X POST http://<host>:7474/db/data/ext/CypherPlugin/graphdb/execute_query -H "Content-Type: application/json" --databinary '{
"query": ca=node:emp(NUM_OFC_CA = {num_ofc_ca}) RETURN distinct ca.NME_CA as `CAName`",
"params": {
"num_ofc_ca": "997015"
}
}'
For a general lucene index query , you need to parametrize the full query:
curl -X POST http://<host>:7474/db/data/ext/CypherPlugin/graphdb/execute_query -H "Content-Type: application/json" --databinary '{
"query": ca=node:emp({num_ofc_ca_query}) RETURN distinct ca.NME_CA as `CAName`",
"params": {
"num_ofc_ca_query": "NUM_OFC_CA:997015"
}
}'
