renderTranslateExecuteSql: Render, translate, execute SQL code

In quinterpriest/DatabaseConnector: Connecting to Various Database Platforms

Render, translate, execute SQL code

Description

This function renders, translates, and executes SQL consisting of one or more statements.

Usage

renderTranslateExecuteSql(
  connection,
  sql,
  profile = FALSE,
  progressBar = TRUE,
  reportOverallTime = TRUE,
  errorReportFile = file.path(getwd(), "errorReportSql.txt"),
  runAsBatch = FALSE,
  oracleTempSchema = NULL,
  tempEmulationSchema = getOption("sqlRenderTempEmulationSchema"),
  ...
)

Arguments

connection	The connection to the database server.
sql	The SQL to be executed
profile	When true, each separate statement is written to file prior to sending to the server, and the time taken to execute a statement is displayed.
progressBar	When true, a progress bar is shown based on the statements in the SQL code.
reportOverallTime	When true, the function will display the overall time taken to execute all statements.
errorReportFile	The file where an error report will be written if an error occurs. Defaults to 'errorReportSql.txt' in the current working directory.
runAsBatch	When true the SQL statements are sent to the server as a single batch, and executed there. This will be faster if you have many small SQL statements, but there will be no progress bar, and no per-statement error messages. If the database platform does not support batched updates the query is executed as ordinarily.
oracleTempSchema	DEPRECATED: use tempEmulationSchema instead.
tempEmulationSchema	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.
...	Parameters that will be used to render the SQL.

Details

This function calls the render and translate functions in the SqlRender package before calling executeSql.

Examples

## Not run: 
connectionDetails <- createConnectionDetails(
  dbms = "postgresql",
  server = "localhost",
  user = "root",
  password = "blah",
  schema = "cdm_v4"
)
conn <- connect(connectionDetails)
renderTranslateExecuteSql(connection,
  sql = "SELECT * INTO #temp FROM @schema.person;",
  schema = "cdm_synpuf"
)
disconnect(conn)
