Hello. I’m one of people who wants to study CDM a lot even it’s hard than I expected.
When I run this code, I’ve got an error below.
cmData ← getDbCohortMethodData(connectionDetails = connDetails,
cdmDatabaseSchema = cdmDbSchema,
oracleTempSchema = NULL,
targetId = 1,
comparatorId = 2,
outcomeIds = 3,
studyStartDate = “”,
studyEndDate = “”,
exposureDatabaseSchema = cohortDbSchema,
exposureTable = cohortTable,
outcomeDatabaseSchema = cohortDbSchema,
outcomeTable = cohortTable,
cdmVersion = cdmVersion,
firstExposureOnly = FALSE,
removeDuplicateSubjects = FALSE,
restrictToCommonPeriod = FALSE,
washoutPeriod = 0,
covariateSettings=FALSE)
|===================================================================== | 50%Error in nchar(object, type = “chars”) :
invalid multibyte string, element 4
What should I do??
