Create the results tables to store PatientLevelPrediction models and results into a database
Source:R/uploadToDatabase.R
createPlpResultTables.RdThis function executes a large set of SQL statements to create tables that can store models and results
Usage
createPlpResultTables(
connectionDetails,
targetDialect = "postgresql",
resultSchema,
deleteTables = TRUE,
createTables = TRUE,
tablePrefix = "",
tempEmulationSchema = getOption("sqlRenderTempEmulationSchema"),
testFile = NULL
)Arguments
- connectionDetails
The database connection details
- targetDialect
The database management system being used
- resultSchema
The name of the database schema that the result tables will be created.
- deleteTables
If true any existing tables matching the PatientLevelPrediction result tables names will be deleted
- createTables
If true the PatientLevelPrediction result tables will be created
- tablePrefix
A string that appends to the PatientLevelPrediction result tables
- tempEmulationSchema
The temp schema used when the database management system is oracle
- testFile
(used for testing) The location of an sql file with the table creation code
Examples
# create a sqlite database with the PatientLevelPrediction result tables
connectionDetails <- DatabaseConnector::createConnectionDetails(
dbms = "sqlite",
server = file.path(tempdir(), "test.sqlite"))
createPlpResultTables(connectionDetails = connectionDetails,
targetDialect = "sqlite",
resultSchema = "main",
tablePrefix = "plp_")
