odbcConnectionColumns_,Snowflake,character-method {odbc}

Connecting to Snowflake via ODBC

Description

odbcConnectionColumns()

If the catalog, or the schema arguments are NULL, attempt to infer by querying for CURRENT_DATABASE() and CURRENT_SCHEMA(). We do this to aid with performance, as the SQLColumns method is more performant when restricted to a particular DB/schema.

Usage

## S4 method for signature 'Snowflake,character'
dbExistsTableForWrite(conn, name, ..., catalog_name = NULL, schema_name = NULL)

Arguments

conn

A DBIConnection object, as returned by dbConnect().

name

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"')

...

Other parameters passed on to methods.

catalog_name, schema_name

Catalog and schema names.
