Description

Append cohort data from multiple cohort tables.

Usage

appendCohortTables(
  connectionDetails = NULL,
  connection = NULL,

  targetCohortDatabaseSchema = NULL,
  targetCohortTable,
  isTempTable = FALSE,

)

Arguments

connectionDetails

An object of type connectionDetails as created using the createConnectionDetails function in the DatabaseConnector package. Can be left NULL if connection is provided.

connection

An object of type connection as created using the connect function in the DatabaseConnector package. Can be left NULL if connectionDetails is provided, in which case a new connection will be opened at the start of the function, and closed when the function finishes.

sourceTables

A data.frame object with the columns sourceCohortDatabaseSchema, sourceCohortTableName.

targetCohortDatabaseSchema

Schema name where your target cohort tables reside. Note that for SQL Server, this should include both the database and schema name, for example 'scratch.dbo'.

targetCohortTable

The name of the target cohort table.

isTempTable

Is the output a temp table. If yes, a new temp table is created. This will required an active connection. Any old temp table is dropped and replaced.

Some database platforms like Oracle and Impala do not truly support temp tables. To emulate temp tables, provide a schema with write privileges where temp tables can be created.

Value

Nothing is returned
