These functions are critical when writing functions that translate R
functions to sql functions. Typically a conversion function should escape
all its inputs and return an sql object.
sql(...)
is.sql(x)
as.sql(x, con)
Arguments
- ...
Character vectors that will be combined into a single SQL
expression.
- x
Object to coerce
- con
Needed when x is directly supplied from the user so that
schema specifications can be quoted using the correct identifiers.
