# S4 method for DatabaseConnectorConnection,character
dbExistsTable(conn, name, databaseSchema = NULL, ...)



A DBIConnection object, as returned by dbConnect().


The table name, passed on to dbQuoteIdentifier(). Options are:

  • a character string with the unquoted DBMS table name, e.g. "table_name",

  • a call to Id() with components to the fully qualified table name, e.g. Id(schema = "my_schema", table = "table_name")

  • a call to SQL() with the quoted and fully qualified table name given verbatim, e.g. SQL('"my_schema"."table_name"')


The name of the database schema. See details for platform-specific details.


Other parameters passed on to methods.


dbExistsTable() returns a logical scalar, TRUE if the table or view specified by the name argument exists, FALSE otherwise.

This includes temporary tables if supported by the database.


The databaseSchema argument is interpreted differently according to the different platforms: SQL Server and PDW: The databaseSchema schema should specify both the database and the schema, e.g. 'my_database.dbo'. Impala: the databaseSchema should specify the database. Oracle: The databaseSchema should specify the Oracle 'user'. All other : The databaseSchema should specify the schema.
